Design your first customer test with AI.
Describe a business idea and the validator writes a Lean Canvas, a hypothesis you can pass or fail, and a first experiment to run with real customers. Then, with a free Rapidly account, turn the experiment into a ready-to-use prompt for the AI you already use.
Free, no signup, about two minutes. 4,000+ ideas tested so far.
“Using rapid experimentation to validate ideas before committing resources almost feels like a cheat code.”
Here's what came back for one of the examples
We ran “Adaptive employee onboarding” through the validator. This is the result, trimmed to fit the page. Yours comes back in the same shape, and the last part is the one you act on: a prompt that builds the experiment for you.
Employee onboarding that adapts training to each role
Lean Canvas
- Problem
- New hires get one-size-fits-all onboarding. Managers rebuild training for every role.
- Solution
- Role-based paths, manager check-ins and readiness tracking.
- Key metrics
- Time to productivity. Manager hours saved.
- Unique value
- New hires productive sooner, with training that fits their actual job.
- Unfair advantage
- A growing library of role templates.
- Channels
- HR communities and LinkedIn outreach.
- Customer segments
- HR and L&D leaders at SaaS companies hiring 10+ people a month.
- Cost structure
- Content setup, integrations, customer success.
- Revenue streams
- Per-seat subscription after a paid pilot.
Hypothesis
AT LEAST 20% OF HR and L&D leaders at fast-growing SaaS companies WILL commit to a paid 60-day pilot IF their onboarding is one-size-fits-all and slows new hires down.
First experiment
Put up a landing page offering the pilot and invite qualified HR leaders to book a call. Nothing is built yet. You run the first group by hand. This is a Fake Door, one of Alberto Savoia's Pretotyping methods.
- Passes if
- 20% of qualified leaders book a call
- Runs for
- 2 weeks
Your experiment prompt
Paste it into Claude, ChatGPT or the AI tool you already use, and it builds what you need to run the test. Here, that's the landing page. Create a Rapidly account to get yours. Your idea comes with you.
Create a one-page landing page for the experiment “Offer the role-based onboarding pilot before it exists”.
It offers a paid 60-day pilot of onboarding that adapts training to each role, for HR and L&D leaders at SaaS companies hiring 10 or more people a month. Open with their problem: new hires get one-size-fits-all onboarding and managers rebuild training for every role.
Use one call to action, “Book a pilot call”, linked to a simple booking form. Don't build the onboarding product. Make it easy to count how many qualified visitors book a call: the test passes if 20% do within 2 weeks.
Frequently asked questions
What is an AI idea validator?
It takes a business idea and writes the first test plan for it: a Lean Canvas, a hypothesis with a number you can pass or fail, and a first experiment to run with real customers.
How does the AI Idea Validator work?
You describe the idea in a sentence or two. The validator uses Pretotyping to fill in a Lean Canvas (problem, customers, solution, channels and so on), write a hypothesis you can test and design a first experiment you can start this week.
Is the AI Idea Validator free?
Yes. It's free and there's no signup. Run as many ideas as you like. To run experiments with your team and track the evidence, Rapidly software has a 30-day free trial.
What's the difference between idea validation and pretotyping?
Idea validation is the goal: finding out whether people actually want what you're planning to build. Pretotyping is the method Alberto Savoia created at Google to get there. You run quick, cheap experiments with real customers and trust what they do, not what they say, before you invest in building.
Try it with your own idea
Give it a go and let us know what you think. If you'd rather work in Claude, Codex or ChatGPT, Rapidly MCP runs the same method through your AI agent.
