The best AI agency for your company in 2026: 11 firms compared
We compared AI agencies and AI consulting firms on published prices, client reviews, measured results and what their contracts let you keep.
The short answer, by budget. You want a US team that takes AI to production: NineTwoThree AI Studio in Boston, from $100,000. You want a US-headquartered firm under $100,000: HatchWorks AI (from $25,000) or Azumo (from $10,000, at $25 to $49 an hour). Both have engineers in Latin America on US hours. You run a mid-sized company and want prices before the first call: ScienceSoft, which publishes its own price for each type of AI project and lists a $5,000 minimum on Clutch.
By sector and size. You work in health or insurance: ScienceSoft again, ISO 27001 certified (the international security standard); in banking or wealth management: Neurons Lab. You are a startup: Krazimo, which caps its team at 15 engineers. You are a large company on AWS: Provectus (on Google Cloud: Quantiphi).
This page is for you if you want to hire an AI agency, not start one: a good part of what ranks for "ai agency" speaks to people launching their own. If you are starting one, read it the other way round: it shows what buyers compare, from published prices to measured results and ownership terms. We compared 39 AI agencies, AI consulting companies and AI development companies on what they publish: prices, client reviews, named results and contract terms. The order follows our scores and can't be bought, and a sponsored spot is always labeled "Sponsored". If you only need a chatbot or an agent, a specialist AI agent developer may be enough. For visibility in ChatGPT answers, you want an AI SEO agency. And if you want AI for campaigns, content and ads, an AI marketing agency is a different job: it runs your marketing with AI, it does not build your systems.
The order can't be bought, and a sponsored spot is always labeled "Sponsored", with its limits written. No link is an affiliate link. Hack'celeration is not ranked. The scores are ours, averaged over five criteria; the Clutch ratings quoted are each agency's own.
The right AI agency for your situation

Best for regulated B2BFocused on financial services, with governance built in. Health or insurance data: ScienceSoft and its ISO 27001.
Best on a small budget$25 to $49 an hour, $10,000 minimum, developers on US hours.
Best for international programsThe largest firm here, with offices in the US, Canada and India, and partner of Google Cloud, AWS and Azure.
AI agencies and AI development companies: budget, rate, score
Minimum budgets and hourly rates come from each agency's site or Clutch profile, in US dollars. The minimum budget is the smallest project an agency accepts: it tells you fastest whether a firm is within reach. The last column says where each team works. Eight of the eleven have offices or engineers outside the US, so check the time zone before the price.
Each overall score is the average of five scores out of 5: expertise, track record, client reviews, transparency and team. It measures public proof (named results, reviews, published prices), not the fit with your profile. Quantiphi ranks last on public proof, but it is the largest firm here, the one built for a program across several countries. At equal scores, track record decides, then client reviews: Vstorm, HatchWorks AI and ScienceSoft share 3.8, in that order. The firms we compared but did not rank are listed in step 2 of the guide below.

One scale for every agency, each criterion from 2 to 5: client reviews by the number of independent reviews (3 under 5, 3.5 from 5, 4 from 20, 4.5 from 50, 5 from 100, minus 0.5 under a 4.0 average), track record by named AI projects with a number (3.5 for one, 4 for two to four, 4.5 for five or more), and transparency by what the agency's own site publishes (3 for a method or terms, 3.5 for an entry price, 4 for prices, 4.5 with the contract length, 5 with the reporting). Expertise gives 3.5 for an AI service page, 4 for an AI specialist or a vendor's entry partner level, 4.5 for an intermediate level and 5 for the top level, read in the vendor's own directory, never on the agency's site; team gives 3 under 10 people, 3.5 from 10 and 4 from 50, plus 0.5 for a published follow-up and 0.5 for a team that works in the US.

NineTwoThree AI Studio
NineTwoThree has built products since 2012 and presents itself as an AI studio of more than 70 people in Boston, with clients such as Experian, FanDuel, Consumer Reports, SimpliSafe, HP and NPR. The method is public: a free strategy call, a discovery sprint, then a rapid validation sprint (a short proof of concept) before the build and the move to production. After launch, it maintains the system or trains your team.
- K&L Wines: 14+ hours saved daily with 99% accurate product matching; VSAC: financial aid comparison time cut by 70%
- Prisonology: legal consultation time cut by 90%; OnTrac: revenue doubled with route sequencing; Amerit: error detection time cut by 90%
- ✓Team based in the US, in your time zone
- ✓A validation sprint before the big budget
- ✗$100,000 minimum rules out most small companies
- ✗Clutch reviews mention team turnover that caused some delays
One of the strongest records of shipped, measured projects here, and our first pick if your budget starts at $100,000. Below that, HatchWorks keeps a US office from $25,000, and ScienceSoft prints its prices.
Vstorm
Vstorm has built AI systems since 2017 from Wrocław, Poland, with more than 25 AI engineers. It does agents, RAG, evaluation and observability (measuring what the model answers), and it rescues stalled pilots and hardens prototypes written fast with AI coding tools. Each mission starts with one workflow and a success threshold agreed before building, then a Proof of Value (a test on your own data that shows whether the gain is real). Its Clutch profile says the work ends in a go or no-go decision backed by measured accuracy and running costs, and that it hands over the code, the prompts and the decision logic.
- Mixam: conversion from about 20% to about 40%; Schmitt-Thompson (health): accuracy from 42% to 98%; Synera: building a workflow from up to an hour to about 2 minutes
- OpenAI Select Partner and Claude Certified Services Partner badges on its own site; 4,000+ GitHub stars on its open source work
- ✓Says it hands over the code, the prompts and the decision logic
- ✓A measured go or no-go before the big spend
- ✓Published engagement lengths, from a 4 to 8 week advisory
- ✗Small team, limited capacity
- ✗European time zone for US clients
The specialist when an agent must work on real data. If all you need is a chatbot, a smaller agent shop may cost less.
HatchWorks AI
HatchWorks AI was founded in 2016 and has 250 to 999 people, with offices in Atlanta, Chicago and Dallas. Its nearshore teams (engineers in nearby countries, in your time zone) work in Costa Rica, Colombia and Peru. It sells three things under one roof: an AI roadmap, AI-assisted software development and change management so your teams adopt what was built. Clients include Cox, AT&T and PwC; partners include Anthropic, Google Cloud and OpenAI.
- Cox: delivery speed up almost 300% with bugs near zero; Cox2M: a chat assistant above 90% accuracy
- One roadmap prioritized 50+ AI ideas for a single company
- ✓Adoption is part of the offer
- ✓Its Clutch profile says you keep ownership of your IP
- ✓Nearshore teams on US hours in Costa Rica, Colombia and Peru
- ✗Many engagements embed its engineers in your team (forward-deployed engineers, AI pods), so you still need someone on your side to direct the work
- ✗No published prices
Our pick when your real risk is that nobody uses the tool: strategy, build and adoption come from one team, on US hours. If you only need engineers to build a spec you already wrote, Azumo charges about half the hourly rate.
ScienceSoft
ScienceSoft is a software company based in McKinney, in the Dallas area of Texas, founded in 1989, with more than 750 IT professionals. Its AI practice does strategy, governance, proofs of concept, generative AI (chatbots, copilots, agents) and forecasting or vision models. Its prices are public: $10,000 to $100,000 for a narrow feature such as an FAQ chatbot, and $50,000 to $150,000 and more for a workflow or an agent. A large platform goes up to $1,000,000 and more.
- ISO 27001, extended by ISO 27701 for personal data; AWS Partner since 2017
- Medical imaging analysis taken from 30% to 90% accuracy
- ✓A $5,000 minimum project on Clutch
- ✓Certificates your compliance team will recognize
- ✗A generalist firm: ask for the AI team by name
- ✗Most public reviews are about apps and security testing, not AI
Our pick for a mid-sized company that wants prices on paper, and the safe pick when security paperwork weighs as much as the model.
Provectus
Provectus, based in San Francisco since 2010, counts more than 400 AI builders and consultants, including over 200 AWS and Claude certified architects. Its engagement model is the clearest we found at this size. A one-week Sprint at a fixed price measures your baseline and runs a cost-benefit analysis. Enable then runs 8 to 14 weeks, paid by milestone. Realize is paid on results, with a quarterly review that proves the value or ends the engagement.
- AWS Premier Tier Services Partner; Preferred partner in Claude's partner directory
- Convex (insurance): a 100-page risk report summarized in 10 minutes; PepsiCo: 2x ROI on optimized campaigns
- Johnson Lambert: a 20% audit efficiency gain across its book
- ✓AWS Premier Tier services partner
- ✓A fixed-price first week before any big commitment
- ✗No verifiable public client reviews
- ✗Built for companies already on AWS
The first call for a large company already on AWS that wants to test the value in a fixed-price week before committing. No public review ties to it, so ask for two references in your industry; on Google Cloud, look at Quantiphi instead.
Azumo
Azumo has built AI apps since 2016, from an office in San Francisco and with developers mainly in South America, many in Argentina. Its team builds chatbots, voice apps, agents, computer vision, RAG and fine-tuned models (models retrained on your data), or joins your team as extra developers. Clients include Meta and Omnicom. It holds SOC 2 (an independent audit of its security controls) and stays independent of model vendors: OpenAI, Anthropic, Gemini or open models.
- Licata Law Firm reports staff time cut by 85% in a Clutch review
- Fairwater Holdings (shipping) says it moved its whole fleet of 41 vessels onto the new platform within six months
- Runs its own open-weight model platform, Valkyrie, next to Claude and other models
- ✓Cheapest hours in the ranking
- ✓No lock-in to one model vendor
- ✓Developers who share your working day, from Latin America
- ✗Team turnover mid-project comes up in reviews, including a recent one
- ✗Sells staff augmentation next to full builds: in that model, you steer the work yourself
Our pick when the hourly rate decides and you can steer the project yourself. Put named engineers in the contract, since reviews mention turnover; if you want the agency to lead, HatchWorks costs more per hour but sells adoption with the build.
InData Labs
InData Labs is a data and AI firm founded in 2014, headquartered in Nicosia, Cyprus, with a US sales office in Miami and an office in Vilnius, Lithuania. It employs 50 to 249 people. It covers generative AI (LLMs, the large language models behind ChatGPT, plus RAG), classic machine learning, data engineering and MLOps (keeping models running in production).
Its site does not print a price list of its own. It gives market price ranges instead: $15,000 to $50,000 for a proof of concept or MVP (a first version you can test), and $75,000 to $200,000 for a project of medium complexity. An enterprise platform runs $400,000 to $2,000,000 and more. A cost calculator turns your project type and size into a range. Its timeline is public too: 1 to 2 weeks of discovery, 1 week of architecture, then 6 to 16 weeks of build before deployment.
- Named clients: Wargaming (fraud detection), AsstrA (freight prices), Flo
- 60% fewer stockouts per quarter in retail, 85% less manual reporting, full ROI in 8 months on demand forecasting
- ✓Phase-by-phase timelines and market price ranges on its site
- ✓A cost calculator before any call
- ✓Data engineering and AI in one team
- ✗Its only US office is a sales office: the other two are in Cyprus and Lithuania, seven hours ahead of New York
- ✗A 2024 client review says it could be more efficient with project proposals and planning calls
- ✗A 3.5-star review of a trading algorithm project says the end result was not met and the cost was well overpriced
A good pick for a mid-sized company that wants a budget range and a schedule early. If you want a team based in the US, NineTwoThree costs more.
Krazimo
Krazimo was founded in 2023 by former Google engineers. Clutch places it in New York, with a second office in Bengaluru, India. It limits its team to 15 engineers and caps active work at 10 projects. It builds custom AI, RAG systems, agents, chatbots and automations, and offers "sovereign AI": open models hosted on your side, so your data stays with you. Clutch lists a $10,000 minimum, but its own budget form starts under $5,000: ask before you rule it out. It also advertises a risk-free trial.
- Pure Restore: revenue from $4.15M to $5.12M (+23%), profit from $445K to $2.04M (+358%), also stated by the client in its Clutch review
- Arivihan: grading time cut by 60%
- ✓A small senior team
- ✓A trial before you commit
- ✗Very young firm
- ✗Capacity capped, so it may ask you to wait
- ✗No office address on its site
The risk is its age: it opened in 2023. Keep the code in your own repository from day one.
Neurons Lab
Neurons Lab, founded in 2019, works from London and Singapore with 50 to 249 people, and focuses on financial services: wealth management, banking and insurance. It builds custom agents with governance, trains teams and delivers through forward-deployed engineers (engineers who sit inside your team). In its own guide, it says a pilot can reach scaled deployment in 8 to 12 weeks. It holds the AWS AI Competency for agentic AI, and says it was named an OpenAI and Anthropic Select partner.
- HSBC: a program that aligns 50+ senior leaders
- Visa: a content system across 9+ markets; a large Asian bank: an assistant that doubles team capacity
- AWS AI Competency in agentic AI; OpenAI and Anthropic Select partner status announced on its site
- ✓Knows finance regulation and governance
- ✓Engineers embedded in your team
- ✗Its 5 public reviews date from 2022 or earlier, before its finance focus
- ✗$100,000 minimum and no US office
Our pick for a bank, insurer or wealth manager that needs AI its regulator can follow. Its public reviews predate its finance focus, so ask for a recent reference; outside finance, or under $100,000, look at ScienceSoft.
Addepto
Addepto was founded in 2017 in Warsaw and is now part of KMS Technology, with a second office in Los Angeles. Its services run from an AI discovery workshop and proofs of concept to data engineering, data governance and Databricks consulting, then agents, LLM apps and MLOps. It says its consulting method draws on 100+ AI projects. It built its own tool, ContextCheck, to evaluate RAG chatbots: a good sign that it checks answers before launch.
- EAG Aero (aviation): an LLM chatbot that drafts aircraft sourcing documents on the client's own AWS setup, a $50,000 to $199,999 project rated 4.5 on Clutch
- Teezily (e-commerce): an image quality detection engine
- ContextCheck, its own tool to test RAG chatbots before launch
- ✓Strong when the data foundation is the real problem
- ✓Entry budget within reach
- ✓Backed by a larger group, KMS Technology
- ✗Few published numbers, many anonymous clients
- ✗An aviation client wanted more say in architecture choices
Our pick when your data is the real problem, before any model. For named, measured results, Vstorm or Krazimo publish more.
Quantiphi
Quantiphi was founded in 2013 and has 1,000 to 9,999 people, with offices in the US (Boston, Princeton, San Jose), Canada (Toronto, Fredericton) and India (Mumbai, Bengaluru, Trivandrum). It builds agents, conversational AI, document AI (reading contracts, forms and invoices) and generative AI, plus the data and cloud work around them. It partners with Google Cloud, AWS, Azure, NVIDIA and Snowflake, and lists 86 patents filed, 19 granted. It won Google Partner of the Year in four categories in 2026, and two industry analyst reports name it a leader in AI services.
- 2026 Google Partner of the Year in four categories; named a leader in AI services in two analyst reports
- A US bank, unnamed: 75% call containment (calls resolved without a human agent) with Five9 and Google Cloud
- Public-sector work for the State of Idaho Controller's Office (budget and audit reporting) and the Commonwealth of Kentucky
- ✓Scale for multi-country programs
- ✓Deepest Google Cloud recognition here
- ✗Not built for a small or mid-sized company
- ✗Almost no public client reviews (none on Clutch)
The Google Cloud counterpart to Provectus, for a company-wide program across several countries. It publishes no client reviews or prices, so get references directly; for a single use case, start with a firm that prints its entry price, such as ScienceSoft or Azumo.
How to choose your AI agency, step by step
How we compare AI consulting services, turned into steps you can follow, for a $10,000 proof of concept or a six-figure program.
Fix the process before you buy AI
Before the callAI on a broken process gives you the same problems, faster. Write down the task, who does it, how long it takes and the one number that says it worked: hours saved, error rate, answers with no human fix. Send that brief to three agencies. If the answer is a simple rule, you need an automation, not AI: our n8n agency ranking compares the firms that build them, and n8n vs Make helps you pick the tool. If your data sits in five tools that disagree, fix that first: AI on bad data gives confident wrong answers.
- Send to
- 3 agencies
- Must include
- One success number
Check the source, then ask for live systems
ShortlistMost "top AI development company" articles come from an agency that ranks itself first, and some still list firms that have closed. Check that reviews are recent and about AI. Then ask for two named projects in production with a measured result. Watch for "agent washing": old chatbots and scripts renamed AI agents.
Also compared, not ranked:
- Tribe AI names no client and shows no client reviews on its site.
- Agency (agen.cy) builds custom AI agents and sells agent consulting, plus its own AgentOps monitoring tool. It publishes no location, prices or client project.
- Agency (agency.inc) sells customer success agents as a product, and has announced it is winding down after its acquisition by Klaviyo.
- Use All Five is a design and technology agency where AI is one service among five, with no AI price or measured AI result.
- Keenfolks is an AI marketing agency for global consumer brands (Nestlé, Coca-Cola, Mars): it runs marketing with AI, it does not build AI systems.
- LeewayHertz ranks itself first in its own list of AI consulting firms. It puts The Hackett Group, which bought it, second, without saying so.
- Master of Code and EffectiveSoft each rank themselves first in a list they publish.
- Appinventiv has two recent Clutch reviews at 0.5 and 2 out of 5, one calling the project an overall failure.
- Ask for
- 2 named live projects
- Red flag
- Unnamed pilots
Pay for a short discovery phase before the firm quote
Before signingA quote written after one call is a guess. Pay for one to two weeks of scoping at a fixed price, then move to milestones: a one-week Sprint at Provectus, a validation sprint at NineTwoThree, a success threshold set before building at Vstorm.
- Length
- 1 to 2 weeks
- Billing
- Fixed price
Compare two quotes line by line
Before signingPut the quotes side by side: scope, named people and their seniority, hourly rate, milestones, what happens after launch. Many leave out the running costs: model usage fees (inference), monitoring, maintenance and retraining. Ask each agency to price the first year of running the system, not only the build.
- Compare
- Scope, team, run cost
- Often missing
- Inference, maintenance
Put ownership and your data in the contract
ContractAsk for full transfer of the code, the prompts, any fine-tuned model weights (the trained model itself) and your data once you pay; a license-only contract is a warning sign. Get a written promise that your data will not train their models, with a deletion deadline, and the right to export everything if you switch. Add how quality is monitored over time.
- You own
- Code, prompts, weights, data
- Must have
- No-training clause
Name the people and call a technical reference
ContractAsk for named engineers and a rule for replacing them: turnover mid-project comes up again and again in client reviews, even at agencies rated 4.9 out of 5. Call a technical lead rather than a buyer, ideally on a project that went badly.
- Ask for
- Named engineers
- Read
- The 4-star reviews
Plan who will use it, and train them
After launchOne large consulting firm estimates that the AI application brings only about 10% of the value of an AI transformation; data and technology bring 20%, people and process 70%. Ask what the agency does for training and handover. If your need is mostly skills, compare our ranking of AI training for employees first.
- Value from the tool
- About 10%
- Value from people
- About 70%
What an AI agency costs, with real numbers
Few agencies print their own prices, so we gathered the ranges they publish. Expect $15,000 to $50,000 for a proof of concept, $75,000 to $200,000 for a project of medium complexity, and $300,000 to $2,000,000 and more for an enterprise platform.
A typical project
Across verified client reviews of AI development projects, the average project comes to about $120,600; the average monthly cost is about $11,550, and a typical project runs 10 months. The most common budget sits between $10,000 and $49,999. The ranked agencies accept projects from $5,000 (ScienceSoft) to $100,000 (NineTwoThree, Neurons Lab).
Hourly rates, agencies and freelancers
Agencies charge from $25-49 an hour (Azumo, nearshore) to $100-149 (NineTwoThree, Vstorm, Krazimo), and up to $150-199 at some product studios. A senior freelance AI engineer charges $130 to $200 an hour in the US, $80 to $140 in Eastern Europe and $65 to $125 in Latin America.
A US-based team under $100,000
In this ranking, NineTwoThree builds from a team in Boston, from $100,000. Under that budget, four ranked firms have a US office, but not all their engineers sit there. HatchWorks (from $25,000) has offices in Atlanta, Chicago and Dallas and engineers in Costa Rica, Colombia and Peru. Azumo (from $10,000) is based in San Francisco, with developers mostly in South America, many in Argentina, one to two hours ahead of Eastern time, depending on the season. ScienceSoft (from $5,000 on Clutch) is headquartered in McKinney, Texas, and Krazimo (from $10,000 on Clutch) lists New York and Bengaluru. Ask each one, in writing, where the engineers on your project will work and how many hours of your day they overlap with.
Prices by type of work
A narrow feature such as an FAQ chatbot: $10,000 to $100,000. A workflow or an agent: $50,000 to $150,000 and more. A full AI application: $100,000 to $300,000 and more. Consulting alone: $6,000 to $140,000 in a large company. Liquid Technologies sells three fixed consulting packages on its Clutch profile. Small, $18,000: a strategy workshop, use-case discovery, a roadmap, a proof of concept and post-deployment support. Medium, $48,000: adds model development, deployment with MLOps, drift monitoring, team training and a dedicated project manager. Large, $140,000: adds computer vision, private or on-premise deployment and compliance alignment (ISO 27001, HIPAA, GDPR, SOC 2).
The billing models
Time and materials: you pay the hours worked, flexible but open-ended. Fixed price: one amount for a set scope, ideal for discovery. Milestones: paid stage by stage, the usual model for a build. Outcome-based: part of the fee depends on the result, offered by a few enterprise firms. Retainer: a monthly fee for ongoing work and maintenance. Whatever the model, usage fees, monitoring, maintenance and retraining are often missing from the quote. Fine-tuning your own model adds 40% to 80% compared with building on an existing API: ask whether you really need it.
Below $10,000
One AI automation agency founder reports that half of potential clients named a budget under $2,000. The same founder advises agencies to target clients with at least $10,000 to $20,000. Below $10,000, a freelancer or a no-code automation usually serves you better than an AI agency. Under $5,000, aim for one automated workflow with an AI step rather than a custom build. Our n8n agency ranking compares the firms that build them, and Krazimo's own budget form starts under $5,000.
- The minimum project size, asked on the first call
- A fixed-price discovery phase before the full quote
- The rate and seniority of each named person
- The cost of one year of running the system
- Who owns the code, prompts, weights and data
AI agency: your questions answered
What is an AI agency?
A company you pay to plan, build and run AI systems for your business. The term covers three kinds of firms. AI marketing agencies use AI for campaigns, content and ads: they run your marketing, they do not build your systems. AI automation agencies add AI steps to the workflows you already run, often with tools such as n8n (see our n8n agency ranking). AI development and consulting companies set the strategy and build custom models, apps and agents: that is what this page ranks, and the best firms here both advise and build. An AI agent, the word you will hear most, is a program that decides its next steps and takes actions, such as updating your CRM, to reach a goal. A chatbot only answers questions, and an automation follows fixed rules someone wrote in advance.
Is hiring an AI agency worth it?
Yes, when your use case has one success number and a budget of at least $10,000 to $20,000. No, when a simple rule would do: an automation handles that for less. And no when a ready-made platform already does the job: compare the best AI agent platforms before you pay for a custom build. The risk is real. Research on enterprise generative AI found a 95% failure rate, with most pilots stalling at little or no measurable impact on profit and loss. The same research found the best returns in back-office automation, while more than half of budgets go to sales and marketing tools. So start with a back-office task you can measure, and pay for a short proof before the full build.
How much does an AI agency cost?
Most AI development projects reviewed on Clutch typically cost $10,000 to $49,999. Most firms listed there charge $24 to $49 an hour; the ranked firms go up to $149. In the price grids agencies publish, the model itself rarely moves a project into the higher bands. What does is the integration with your older systems, compliance requirements, and a model trained on your own data rather than an existing API. So ask each agency which of the three your quote includes, and what the first year of running it will cost. Advice alone can cost less: ScienceSoft prints $15,000 for AI product consulting for a startup.
How long before an AI project shows results?
Expect 4 to 8 weeks for a strategy, 2 to 4 months for a proof of concept, and 6 to 12 months or more for a full deployment. Narrow use cases go faster: one finance specialist says it can take a pilot to scaled deployment in 8 to 12 weeks.
Should you hire an AI agency, a freelancer or an in-house team?
It depends on how central AI is to your product. A freelancer fits small automations under $10,000. An in-house hire fits when AI is your core product for years: a senior AI engineer costs $180,000 to $280,000 in base salary in North America. An agency fits in between: a full team for a few months, and someone accountable. Research on generative AI projects found that buying from specialized vendors succeeded about 67% of the time. Internal builds succeeded only one-third as often (a correlation, not a proof).
What are good alternatives to the big AI consulting firms?
Specialized AI agencies and boutiques. BCG X, Accenture, Deloitte, EY and IBM Consulting suit company-wide transformations with seven-figure budgets. For one use case or a first product, a specialist ranked here works at a smaller scale and closer to your team. If you mostly need adoption, firms such as Every Consulting focus on training and strategy, run by people who build with AI rather than management consultants.
What certifications should an AI development company have?
ISO 27001 or SOC 2 Type II for security, plus a signed HIPAA business associate agreement if you handle US health data. Here, ScienceSoft holds ISO 27001, and HatchWorks shows a SOC 2 Type 1 report. Azumo shows SOC 2 without naming the type, and NineTwoThree an AICPA SOC badge. So ask for the Type II report, which tests the controls over several months. NineTwoThree also shows HIPAA. Check any claimed AWS or Google Cloud partner level yourself in the free AWS Partner and Google Cloud partner directories: a logo on a website proves nothing. If you already know your model (see our reviews of Claude and ChatGPT), check the vendor's own partner list too. In Claude's partner directory, Provectus is a Preferred partner and Quantiphi a Select partner. Vstorm, Krazimo and Neurons Lab announce OpenAI Select Partner badges, and ScienceSoft, Vstorm and Neurons Lab Claude partner badges, on their own sites; Claude's directory lists none of them, so ask the vendor to confirm before you count them.
What questions should you ask an AI agency?
Six questions sort most agencies in one call. (1) Which two projects like yours are in production, with a measured result, and can you call their technical lead? (2) Who owns the code, the prompts, any trained model and your data once you pay? (3) Will your data train any model, and when is it deleted? (4) Which engineers will work on your project, where do they work, and how are they replaced if they leave? (5) What will the first year of running the system cost? (6) How will you see progress during the build? InData Labs, for one, publishes weekly demos and shared Jira and Slack access during its build sprints. Be wary of any promise of a guaranteed return: every result quoted on an agency's site is self-reported, including the ones on this page.
