GeminiWe build internal tools on Retool, not just in theory.
Most Retool trainings are run by people who read the docs the night before. At Hack'celeration it's the opposite: Apps assembled from components, resources wired into Postgres and APIs, Workflows that run the ops, that's our daily agency work. Everything we teach you, we practice on shipped projects. We know the traps (the unconfirmed mutation that wrecks a row, the RBAC bolted on after the fact) because we've already solved them.
- We build internal tools on Retool for real clients every week, not just in theory
- 1-on-1 format: the trainer adapts to your level, beginner or seasoned dev
- We tell you when Retool isn't the right call (sometimes a spreadsheet or a normal customer app is enough)
- We start from your real account and your actual data sources, not a dummy example
Four pillars so your internal tools actually get used.
A badly built Retool means a half-finished dashboard nobody opens, mutations with no guardrails, an app glued onto a manual process. Most of the trouble comes from the build, not the tool. We pick up your real account and work through the four pillars together.
- Apps and components
Internal tools you build yourself
We teach you to assemble your Retool Apps from the component library: tables, forms, buttons, charts, modals, tabs, file uploads. You start from your own need (a CRUD admin panel, an ops dashboard, an approval flow) and put it on screen, wired to live data. By the end you can build the screen your team needs without waiting a quarter of dev time.

Wire Retool into your databases and your APIs
An internal tool is only as good as the data behind it. Together we set up Retool resources on your Postgres, MySQL, MongoDB, BigQuery, Snowflake, your REST and GraphQL APIs, Stripe. You learn to write the queries (SQL, REST, GraphQL) that read and write safely, to use the Retool Database when you need a quick store, and to keep mutations behind confirmation and permissions.

Workflows that run the ops behind the app
The UI is half the job. We teach you to build Retool Workflows for automation: scheduled jobs, webhooks, data syncs, alerts, the cron tasks you run by hand today. An approval in the app triggers a workflow, the workflow updates the database and pings Slack. Since we're an automation agency first, you leave knowing how to think of the app and the pipeline as one system.
See the automation - RBAC, audit logs, self-hosting
Lock down access and deploy it safely
Internal tools touch your real data, so access control isn't optional. You learn to set RBAC and permission groups so each team only sees what it should, to turn on audit logs to know who changed what, and to deploy self-hosted or on-prem when compliance demands your data stays in your VPC. We also cover version control and release stages. And if you want to go further on the pipeline, we run an n8n training too.

Meet our trainers, leave with a plan.
Drop your email. We get back to you to connect you with a Hack'celeration-certified trainer: we look at your Retool account, spot the manual work to kill and your data sources, and tell you where to start. No commitment, even if you don't take the training.
- A diagnosis of your need (tools to build, spreadsheets, data sources)
- The first Apps to build, in priority order
- The right 1-on-1 format for your level and your team's
- An honest take: Retool or another tool for your case
Your Retool program, step by step.
Five steps, no skipping. Each one on your real account, with a clear deliverable. From the first session we map the manual work to kill. By the end, you build your Apps and ship your Workflows without us.
- Step 1 · Scoping your need
We open your real Retool and find the manual work to kill
First session, we share your screen and look together. Which spreadsheet is secretly your CRM? Which database query do you run by hand every morning? Which approval lives in email threads? We list the screens that would actually save your team time and the data sources behind them. You leave with a clear target and the order we'll build in. No theory, your real account.
- Step 2 · Connect the data
Retool resources on your databases and APIs, safely
We go after the data first, because an App without reliable data is useless. We set up Retool resources on your Postgres, MySQL, MongoDB, BigQuery, Snowflake and your REST and GraphQL APIs, then you learn to write the queries that read and write what the app needs. We set permissions and confirmations on anything destructive from day one, so you can't silently corrupt your source of truth while you're learning.
- Step 3 · Build the App
Apps and components on your real cases, not a dummy
We build your tool. We assemble Retool Apps from the components: tables, forms, charts, modals, tabs, the screens your team actually needs. You practice on your own case, not a fake demo. We wire the queries behind every action and keep destructive buttons behind confirmation. You finish with an App that works, connected to your real data, and the reflex to build more.
- Step 4 · Workflows and automation
We plug Retool Workflows in behind the app
This is where Retool gets powerful. We build Retool Workflows for automation: scheduled jobs, webhooks, data syncs, alerts, the cron jobs you run by hand. An approval in the app triggers a workflow, the workflow updates the database and alerts on Slack. The app and its automation ship together. You leave knowing how to think of the tool and the pipeline as one system, not two disconnected projects.
- Step 5 · Security and autonomy
You lock down access and ship without us
The number one goal: you become autonomous. You learn to set RBAC and permission groups, to turn on audit logs, to deploy self-hosted or on-prem if your data must stay in your VPC, and to use version control and release stages to review changes before prod. By the end, your team edits queries, adds components and ships without us. And if you want to delegate later, we also run a Retool agency, but that's not the point here.
Why train 1-on-1 with us.
- 300+Pros already trained on no-code and AI
More than 300 people have gone through our trainings across France and Europe. Ops teams, devs, small-business founders. Not vanity numbers: people who left knowing how to build their own internal tools instead of waiting for them.
- 4.7/5Rating across 334 verified reviews
Average rating of 4.7 out of 5, across 334 reviews. We won't promise it's all magic: you have to build on your real account and your real data. But the 1-on-1 format makes the difference on a tool as broad as Retool.
- 1:1A dedicated expert, not a class of 100
You're not a number in a webinar. A trainer opens your real Retool account, looks at your data sources, and works through your actual cases. We schedule sessions around your availability, replays included.

The questions we get the most.
What is a 1-on-1 Retool training?
An individual program with an expert who builds internal tools on Retool, not a class of 100 people. We open your real account, look at your data sources, and work through your actual cases: Apps and components, resources and queries, Workflows, RBAC. You ask your questions live, the trainer adapts the pace to your level. We schedule sessions around your availability, and you leave with a working App every time. That's what makes the difference on a tool as broad as Retool.How much does the Retool training cost?
There is no single price. We connect you with a trainer certified by Hack'celeration, matched to your need and your level. It varies from one trainer to another, based on their profile and the format that fits your project.Which databases and APIs do you teach connecting Retool to?
Most of what you already run. Retool resources connect to Postgres, MySQL, MongoDB, Microsoft SQL Server, Amazon Redshift, BigQuery and Snowflake, plus REST and GraphQL APIs and services like Stripe, Twilio and Slack. We teach you to write the queries that read and write your data with the right permissions and confirmations. If you need a quick store, we cover the Retool Database and how to migrate the data cleanly once you outgrow it. We start from your real sources, not an example.Do I need to be technical to take the Retool training?
No, not necessarily. Retool has a visual interface to assemble Apps from components. To go further (SQL and API queries, Workflows), a bit of technical logic helps, but the 1-on-1 format is built exactly for that: we start from your exact level. Beginner, we go step by step and write the queries together. Seasoned dev, we jump straight to advanced resources, Workflows and self-hosting. You move at your own pace on your real cases.What are Retool Workflows and do I need them?
Retool Workflows are the automation layer behind your apps: scheduled jobs, webhooks, data syncs and alerts that run on a trigger or a schedule. You need them when the app isn't the whole job: an approval has to update a database and ping Slack, or a nightly sync has to pull data from an API. In training, we teach you to think of the app and its Workflows as one system. If your tool is just read-and-edit with no automation behind it, we tell you and we don't pile on needless complexity.Can Retool be self-hosted and is it safe for our data?
Yes. Retool can be deployed self-hosted or on-prem so your data stays in your VPC, which matters when compliance won't allow it on a vendor's cloud. Security is a real part of the training: we teach you to set RBAC and permission groups so each team only sees what it should, to turn on audit logs to know who changed what, to keep destructive actions behind confirmation, and to use version control and release stages so changes are reviewed before prod.When is Retool NOT the right call?
We'll tell you straight. Retool is built for internal tools, so it's a poor choice for a polished customer-facing or marketing app where you need full design control and pixel-perfect rendering; you'll fight the framework. And if your need is genuinely tiny, a few rows two people edit, a spreadsheet is enough and a Retool App is overkill. We'd rather tell you than train you on a tool for a problem it doesn't solve. Where Retool shines is internal software wired to real data.After the training, can my team maintain the tools alone?
Yes, that's the whole point. The project lives in your own Retool org, under version control, so your team can edit queries, add components and ship changes without us. We train you to give a full tour of your Apps and Workflows so whoever maintains them knows how it's wired. If you ever leave Retool, the data in your databases is yours. The 1-on-1 training aims precisely at you no longer needing an agency for your internal tools.How long until I can build a Retool App?
For a first scoped App (one or two data sources, the key screens, basic permissions), a few sessions are often enough, that's the whole appeal of Retool. Mastering Workflows, fine-grained RBAC and self-hosting takes a bit longer. We move in batches so you get a working tool fast and practice on something real, rather than stacking theory. From the first session, we build on your real account so you see the effect quickly.Is the training online or in person?
100% online, over video, 1-on-1. You join the sessions from anywhere, we share your screen and your Retool account live. Sessions are recorded if you want to revisit them. The individual format means real interaction: you're not a number in a webinar of 100, the trainer answers your questions about your setup and your real data sources. That's what makes learning concrete on a tool as broad as Retool.
