The best demand generation agency for B2B in 2026: 9 compared
We compared demand generation agencies on published prices, independent reviews, named results and the terms of their contracts.
The short answer: SmartBug Media leads our ranking at 4.4 out of 5, with 825 reviews at 5.0 in HubSpot's partner directory and HubSpot's highest partner tier, Elite. By profile: for a long, technical B2B sale, Ironpaper, a demand gen specialist and HubSpot Platinum partner. For SaaS that wants part of the fee tied to results, Kalungi, with seven named clients and a pay-for-performance option. For a smaller budget, Gripped, from £3,500 a month on a rolling contract. For a large budget across several countries, Directive, from $250,000 a project on Clutch, with offices in the US, Mexico City, London and Toronto. To test a team before a retainer, Powered by Search, which sells a $14,900 audit. For heavy ad budgets, Refine Labs, from $14,000 a month with a 6-month minimum.
Demand generation means creating interest among buyers who are not shopping yet, so they think of you when they are. Lead generation is different: it captures people already looking, often with cold outreach or booked meetings. Several pages that rank for this search mix the two. We kept agencies that run multichannel demand programs (content, paid media, search, ABM) and left out appointment-setting firms. We compared 30 agencies on what they publish. The order follows our scores, and a sponsored spot is always labeled "Sponsored".
The ranking is editorial: a sponsored spot is always labeled on its listing, and no affiliate link changes a score. Hack'celeration is not ranked. The scores are ours, averaged over five criteria; the Clutch and HubSpot ratings quoted are each agency's own.

Demand generation agencies: price, terms, score
Prices come from each agency's own site when it publishes them, otherwise from HubSpot's partner directory or Clutch, in the currency the agency uses. Only three of the nine print prices: Refine Labs, Powered by Search and Gripped.
Also compared and left out: The ABM Agency, which ranks on Google for this search with a page that names no client (it is an account-based marketing specialist first); ProperExpression, whose demand gen page shows no named client and no number; PAN Communications, a PR agency that adds demand gen to its press work; Callbox, SalesCaptain and Salesbread, which sell outbound prospecting and booked meetings (lead generation), as do Belkins, Martal Group, CIENCE and SalesRoads; Hey Digital, a paid ads agency; Single Grain, which ranks for this search with a full-service demand gen page that names clients (Amazon, Nextiva) but no figure and no price; inBeat, whose demand gen page gives only unnamed averages and whose core is creator and paid social work; and The B2B Playbook, whose site now sells a revenue alignment framework rather than an agency service.
Each overall score is the average of five scores out of 5. At equal scores, track record decides, then the number of independent reviews: Kalungi and Ironpaper both score 4.1, Kalungi first on track record; Gripped, Directive and Powered by Search all score 4.0, Gripped first on track record, then Directive on reviews.

One scale for all nine agencies, each criterion from 2 to 5. Client reviews follow the number of independent reviews: 2 with none, 3 under 5 or with only quotes on the agency's own site, 3.5 from 5, 4 from 20, 4.5 from 50, 5 from 100, minus 0.5 under a 4.0 average. Track record counts named clients with a measured demand gen result: 3 for named clients without a number, 3.5 for one result, 4 for two to four, 4.5 for five or more, 5 for five or more measured over time. Transparency reflects what the agency's own site publishes: 3 for a method, terms or a directory price, 3.5 for an entry price, 4 for prices, 4.5 with the contract length, 5 with the reporting. Expertise gives 3 when demand gen is one service among others, 3.5 for a service page with named projects, 4 for a specialist and 4.5 for a specialist with five named projects; a HubSpot partner tier counts too, and the higher of the two is kept: 4 for Partner, 4.5 for Gold, Platinum or Diamond, 5 for Elite. Team gives 3 under 10 people or when the size is unknown, 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 English-speaking market.

SmartBug Media
SmartBug Media was founded in 2007 and has grown to nearly 300 people working remotely from Montreal to Mexico City. Its demand generation page builds on inbound (content and search that buyers find on their own) and adds paid media, partner marketing, review sites and PR. HubSpot lists it as an Elite Solutions Partner, the top tier of its agency program, which tells you the CRM side will be handled by people who know it well.
- CloudVelox: +540% marketing-generated leads and +2,422% traffic from social media
- Ashling Partners: 7x booth visitors and 183 new MQLs (marketing qualified leads) from one conference
- 825 reviews at 5.0 in the HubSpot directory, Elite Solutions Partner
- ✓Review volume no other agency here comes close to
- ✓CRM, automation and campaigns handled by the same team
- ✗Fees are quoted on the first call; the HubSpot directory only shows a $5,000+ floor
- ✗Few named demand gen numbers for its size; ask for two in your sector
Our first pick if HubSpot is your CRM and you want proof that many clients stayed happy. If you want a firm price before the first call, look at Powered by Search, or at the starting prices Refine Labs and Gripped publish.
Kalungi
Kalungi, based in Kirkland near Seattle, works only with B2B SaaS and says it has served 280+ SaaS companies. Its engagements are sized by revenue: a full-service team for $5 to $10 million ARR, lighter tiers below. On contracts of three months or more, part of the fee depends on quarterly OKRs (objectives and key results): you can pay as little as 0% of the variable part, or up to 125% if the team overdelivers.
- DataGuard: +330% MQLs and $4M in pipeline; CPGvision: $4.7M in pipeline
- Avid: from under $300K to $3M+ ARR; Patch: +1,500% MQLs
- Diamond Solutions Partner in HubSpot's directory, 34 reviews at 5.0
- ✓The deepest set of named SaaS results on this page
- ✓Part of the fee tied to goals you agree on
- ✗SaaS only: a manufacturer or a services firm should look elsewhere
- ✗No price list, and overperformance can cost you 25% more on the variable part
The strongest record of named results here for a SaaS company. Read the OKR clause carefully: the same mechanism that lowers your bill in a bad quarter raises it in a good one.
Ironpaper
Ironpaper was founded in New York in 2003 and has 70 people. Its service page explains demand gen as reaching buyers who are 70% to 90% through their research before they talk to a vendor. HubSpot lists it as a Platinum Solutions Partner. It also runs account-based programs (ABM: campaigns aimed at a named list of target companies).
- Solartis: +86% MQLs over six months and 10 SQLs (sales qualified leads) in a month
- Goddard Technologies: +732% website conversions and $3.5M in influenced opportunities
- Platinum Solutions Partner in HubSpot's directory, 23 reviews at 5.0
- ✓Demand gen is its main offer, not a side service
- ✓Fits long sales cycles with several decision makers
- ✗No prices published
- ✗Only one of its named results (Goddard) is stated in pipeline value
A focused demand gen shop with a long history and real reviews. Ask it to tie a result in your sector to pipeline value, as it did for Goddard, since most of the numbers it publishes stop at the lead.
Gripped
Gripped is a London agency for B2B SaaS, AI and tech companies between £2 million and £20 million ARR. Its pricing page lists three tiers, from strategic guidance at £3,500 a month to a full outsourced team at £15,000 a month, and says most clients spend £8,000 to £12,000 a month. Ad budgets are billed separately and typically run £5,000 to £150,000+ a month.
- Crownpeak: £1.3M in pipeline in one quarter
- Cloudbooking: £2.4M in pipeline; Blackdot: £2.1M in pipeline from demand generation
- Nexstor: £2M return from a £60K paid budget
- Rolling contract, three months' notice at any point
- ✓Prices and exit terms in writing
- ✓Strong review base on Clutch
- ✗Prices in pounds and a London team: less natural for a US-only company
- ✗Three months' notice still binds you for a quarter
A solid choice for a SaaS team that wants to read the price and the exit before the call. For a US company, check that its hours match yours.
Directive
Directive has served B2B companies since 2013. It has 130+ strategists and offices in Orange County, Austin, New York, Mexico City, London and Toronto. Its demand gen page mixes content-led SEO with paid campaigns, and it publishes real client reports with the recommendations behind each result.
- Case Status: +135% quarter-over-quarter demo requests; AxisCare: +200% demos and +70% traffic
- Inscribe: +237% keyword rankings and +32% organic traffic from content-led SEO
- 56 Clutch reviews at 4.8
- ✓Large, senior team across six offices
- ✓Client reports you can read before the call
- ✗The highest minimum on this page: $250,000+ on Clutch
- ✗Hourly rate of $300+ prices out most small companies
A safe choice if your budget is large: reviews, named results and a big team. Below a $250,000 project budget, Kalungi, Gripped or Powered by Search fit better.
Powered by Search
Powered by Search is a Toronto agency for B2B SaaS that says it has helped 200+ companies. Its pricing page is unusually complete: three monthly plans for paid media, and three one-time offers. If you sign a retainer within 30 days of the $2,500 Power Hour or the $14,900 audit, the full amount is credited to your first invoice. It says plainly who it is not for: B2C brands and buyers looking for the cheapest CPM.
- TouchBistro: +324% demos in six months
- PointClickCare: 2,000+ leads from LinkedIn Ads
- Audit fee credited to the first invoice within 30 days
- Platinum Solutions Partner in HubSpot's directory
- ✓Prices for every plan, monthly or one-time
- ✓A low-risk way to test the team: the audit
- ✗Almost no independent reviews
- ✗No minimum term or notice period published: ask before signing
The best way on this page to try before you commit: buy the audit, judge the plan, then decide. Ask for references, since reviews are thin.
Refine Labs
Refine Labs, fully remote across the US and Canada, says it has served 300+ B2B tech companies since 2019. Its pricing page lists paid media management from $14,000 a month, a full demand and media service from $26,000 a month (both with a 6-month minimum), creative only from $5,000 a month (3-month minimum), and a six-week diagnostic from $35,000. It has acquired MOBI Solutions, a marketing operations and analytics firm.
- Loxo: +45% ARR, with hand raisers up more than 50% in the first month of ads
- Clari: 64% higher deal conversion and 67% lower acquisition cost in nine months; Firstup: +46% hand raisers and +59% high-intent pipeline
- Full Service includes board-ready pipeline reporting and a monthly review
- ✓You know the starting price, the term and the reporting before the call
- ✓Strategy and paid media run by the same people
- ✗No independent reviews to check
- ✗Built for companies spending heavily on ads: $14,000 a month is the floor
Starting prices, terms and reporting are in writing, but each price is a floor that grows with your ad budget. The missing piece is independent reviews, so ask for two client references before you sign.
Walker Sands
Walker Sands was founded in 2001 and says it has served hundreds of B2B clients. It started in PR and now runs demand gen, paid media and SEO under a method it calls Outcome-based Marketing: agree on the business outcome first, then pick the channels. Its demand gen page links three case studies with figures: Sendbird, CloudCraze and Miller Heiman Group.
- Sendbird: 4,028 MQLs and 342 opportunities worth $6.4M in pipeline from the paid program
- CloudCraze: 3,434 leads and $2.7M+ in new business
- Miller Heiman Group: web leads +100% year over year
- PR and demand gen in one agency
- ✓Useful if press coverage is part of your plan
- ✓A method focused on business outcomes
- ✓4.8 out of 5 from 9 Clutch reviews
- ✗No price published, and only nine reviews on Clutch
- ✗Its results sit on separate case study pages, not on its demand gen page
Worth a call if PR matters to your launch. Ask how the Sendbird pipeline was attributed between paid media and the rest of the program before you compare it with the agencies above.
Elevation B2B
Elevation B2B, run by its founders, calls itself one of the first B2B-focused marketing agencies in the US. Its demand gen page sets out seven pillars, from research and positioning to measurement, and its work spans rebrands, ABM and marketing technology. Two measured cases are on the page: JCB, a global brand new to the US market, with 2,968 qualified leads in less than three months, and Cox Automotive, where a campaign revived inactive leads into 700 extra car sales.
- JCB: 2,968 qualified leads in less than three months
- Cox Automotive: 700 extra car sales from revived inactive leads
- A published method in seven pillars, from research to measurement
- ✓Brand and demand under one roof
- ✓A clear step-by-step method on its page
- ✗Thin public proof: two named results, no reviews, no team size
- ✗No price published
Ranked for its method more than its proof. Ask for a named result closer to your sector before you shortlist it.
How to choose your demand generation agency, step by step
The checks we used to compare agencies, turned into steps you can follow before you sign.
Decide if you need demand gen or lead gen
Before the searchIf your sales team needs meetings next month, you are buying lead generation: outbound emails, calls, booked demos. Our ranking of B2B prospecting agencies covers that job. Demand gen works on the buyers who are not shopping yet, with content, paid social, search and events, so that you are on the shortlist when they start. Most companies need both, but they need to know which one they are paying for. An agency that promises a set number of meetings per month is selling the first one.
- Lead gen
- Meetings now
- Demand gen
- Pipeline in 3 to 6 months
Write a brief around pipeline, not leads
Before the callGive each agency the same four numbers: your average deal size, your sales cycle, your monthly marketing budget (fee plus ads) and the pipeline you need per quarter. Add the CRM you use; if it is HubSpot, our HubSpot review shows what the tool already does without an agency. An agency that asks about your win rate and sales cycle in the first call is thinking about revenue; one that asks only about lead volume is not. If your CRM is still a spreadsheet, fix that first: our CRM ranking helps.
- Send to
- 3 agencies
- Must include
- Deal size and sales cycle
Ask for a named result in pipeline or revenue
ShortlistAn MQL count proves activity, not demand. Ask for two named clients close to your size, with pipeline or revenue before and after, then call one of them. On this page, Kalungi, Gripped, Walker Sands, Refine Labs and Ironpaper (for Goddard) publish named pipeline or ARR results; SmartBug's $3M pipeline story and Refine Labs' portfolio averages name no client, so they tell you less. Most of the ranked agencies wrote or appear in the rankings that rank for this search, some ranking themselves first: read those with that in mind.
- Ask for
- 2 named clients
- Metric
- Pipeline or revenue
Meet the people who will run your account
ShortlistThe most common complaint about agencies is the switch: senior people in the pitch, juniors on the account. Ask who your day-to-day contact is, how many other clients they run, and meet them before you sign. Refine Labs' full-service plan names two dedicated people, a Director of Demand Generation and a Performance Marketing Manager; Powered by Search names the roles in each plan, from one strategist to a team of five or six.
- Ask
- Clients per manager
- Meet
- The day-to-day lead
Read the term, the notice and who owns the accounts
Before signingCheck three things. The minimum term: Refine Labs asks for 6 months on its main plans, Gripped works on a rolling contract with three months' notice. Who owns the ad accounts, the tracking and the content: open them in your company's name and give the agency access, never the reverse. And who pays the ads: at Gripped, ad budgets are billed outside the retainer, which is the norm. If the agency also runs your marketing automation, our marketing automation agency ranking covers what to keep in your own hands.
- Typical term
- 3 to 6 months
- Accounts
- In your name
Start with an audit or a short first term
First 90 daysSeveral agencies sell a first step before the retainer: Powered by Search's $14,900 Pipeline Audit (credited to the first invoice if you sign within 30 days), Refine Labs' six-week assessment from $35,000. Agree on what the first 90 days should show: engagement from your target accounts, more inbound conversations, then pipeline. Agree too on how it is measured: self-reported attribution (asking buyers where they heard of you) and CRM data, not each ad platform's own count. Our ranking of marketing attribution software covers the tools.
- Audit
- $14,900 to $35,000
- First review
- Day 90
What a demand generation agency costs, with real numbers
Expect two bills: the agency fee and the ad spend, which goes to LinkedIn, Google or Meta. Among the agencies here that print prices, monthly fees start at £3,500 (Gripped) and $5,000 billed quarterly, or $6,000 month to month (Powered by Search), and full programs start at $26,000 a month (Refine Labs).
Monthly retainer
The standard model. Gripped lists £3,500, £7,500 and £15,000 a month, and says most clients spend £8,000 to £12,000. Powered by Search lists $5,000, $12,000 and $18,000 a month for paid media when billed quarterly, or $6,000, $14,400 and $21,600 month to month. Refine Labs starts at $14,000 for paid media and $26,000 for strategy plus paid media. Published retainers in this market run from about $2,250 to beyond $20,000 a month.
Agency, consultant or in-house
An agency makes sense when you need several channels run at once (content, paid social, search, ABM) and cannot hire for each. A consultant fits when you only need the strategy and a team to run it already exists: a one-time audit, such as Powered by Search's $14,900 Pipeline Audit or Refine Labs' assessment from $35,000, is the closest thing among the agencies here. Building in-house wins once you can fund about two senior marketers for the long run, since you keep the knowledge and the accounts. Many companies mix the two: an audit or a short agency contract first, then the plan moved in-house.
One-time audit or sprint
A fixed fee to diagnose before you commit: $2,500 for a one-hour strategy session and $14,900 for a pipeline audit at Powered by Search, $25,000 for an execution sprint, and from $35,000 for Refine Labs' six-week assessment. Ask whether the fee is credited if you sign afterwards.
Pay for performance
Kalungi ties part of the fee to quarterly goals on contracts of three months or more: from 0% to 125% of the variable part. It lowers your risk in a bad quarter and raises your bill in a good one. Define the goals in pipeline, not in lead counts.
Minimum project size
Agencies without a price list show a floor in directories: $5,000+ in HubSpot's directory for SmartBug Media, Kalungi and Ironpaper; $250,000+ and $300+ an hour on Clutch for Directive.
Ad spend on top
Media is billed separately everywhere on this page. Gripped's clients typically spend £5,000 to £150,000+ a month on ads. A common starting point is $3,000 to $5,000 a month on LinkedIn and as much on Google. If paid media is most of the job, our performance marketing agency ranking compares the specialists.
- The fee at your budget, and what it covers
- Ad spend: billed directly by the platforms

- Ad accounts, tracking and content in your name

Demand generation agency: your questions answered
What does a demand generation agency do?
It makes the buyers who are not shopping yet know and trust you, so you are on their shortlist when they start. In practice: positioning, content, paid social (LinkedIn first in B2B), search, events and ABM, measured on pipeline rather than on lead counts. Unlike a lead gen firm that sells booked meetings (Belkins, Callbox, SalesRoads), it works on buyers before they raise their hand. If you want AI built into that work, our AI marketing agency ranking covers it.
What is the difference between a demand generation agency and an ABM agency?
An ABM (account-based marketing) agency aims at a named list of target companies, with ads, content and sales plays built for each account. A demand gen agency reaches the whole market you could sell to, then lets the best-fit buyers come forward. Many do both: Ironpaper runs account-based programs next to its demand gen work, while The ABM Agency, which ranks for this search, is an ABM specialist first. Pick ABM when your deals are large and your buyers fit on a known list; pick demand gen when you do not yet know all of them.
Should I hire a demand generation agency, a consultant or build in-house?
An agency for multichannel execution you cannot staff, a consultant when you only need the strategy, in-house once you can fund about two senior marketers for the long run. A common middle path is a paid audit, then running the plan yourself. Before buying one, ask for a sample deliverable: it should be a plan your team can run without the agency, with channels, budgets and a calendar. Refine Labs' assessment, for example, ends with a 12-month demand plan.
How long before a demand generation agency shows results?
Count about 90 days for the first sales-qualified leads, and revenue from month four or later. The ABM Agency puts the average at 90 days from launch to the handoff of sales-qualified leads. Ask the agency what it will report at day 30 and day 60, before pipeline exists: target-account engagement, branded search, self-reported attribution. An agency that promises pipeline in the first month is probably doing lead gen.
How much does a demand generation agency cost per hour?
Most do not sell by the hour, but their Clutch profiles show the band they quote from: $100 to $149 an hour for Gripped and Kalungi, $300+ for Directive. Kalungi's Clutch profile also lists a $25,000+ minimum project, above the $5,000+ floor in HubSpot's directory, so ask which floor applies to a demand gen retainer before you compare quotes.
What should I ask a demand generation agency before signing?
Five questions: who runs my account day to day, and how many other clients do they have? Can you show two named clients with pipeline before and after? What is the minimum term and the notice? Who owns the ad accounts and the data? How will you measure results in my CRM? Write the answers into the contract.
Is a demand generation agency worth it for a small company?
Only if you can fund it for at least six months, ads included. Below roughly $5,000 to $10,000 a month in total, a freelancer or one senior hire often does more. Read the ideal client each agency describes before you call: several size their offer by revenue, such as Kalungi by ARR band or Gripped for £2 million to £20 million ARR. A lighter first step is a one-time audit, then running the plan in-house.
What KPIs should a demand generation agency report?
Five, all read in your CRM: pipeline created, pipeline influenced, self-reported attribution (the "how did you hear about us" field), cost per opportunity and sales cycle length. Leads and clicks can sit in the report, but not as the goal. Ask for a partner seat in your own CRM, not a separate portal, so the data stays yours. Four of the ranked agencies show a HubSpot partner tier in its directory (SmartBug Media as Elite, Kalungi as Diamond, Ironpaper and Powered by Search as Platinum).
Do demand generation agencies guarantee results?
We found no revenue guarantee among the nine agencies here; Kalungi's pay-for-performance option, tied to quarterly goals, is the closest thing. If an agency offers a guarantee, check four points in the clause: the metric (pipeline or meetings in your CRM, not leads counted by the ad platforms), who measures it, over which period, and the remedy if it is missed (a refund, free work, or an exit without notice).
