AI-assisted MVP

AI-assisted prototypes and MVPs to validate your idea

Before spending months on development, you need to know whether the idea works with real users. I combine product design with AI tools to get to a working prototype or a lean MVP you can test, using AI to iterate on something concrete.

Who it's for

  • Founders with an idea that needs to move from idea to something people can use and test.
  • Teams that want to test a new feature without slowing down the roadmap.
  • Entrepreneurs who need something concrete to show investors or first customers.

What's included

  • Kickoff workshop: problem, user, hypotheses and what the MVP has to prove.
  • Scope cut: what goes into the first version and what does not.
  • Essential flows and UI.
  • Functional prototype or web MVP, with technologies chosen according to what each project needs.
  • Basic guide for testing it with users.
  • Recommendations for the next stage.
  • Maintenance and management, if you need it: I take care of the project's accounts, connect the services and integrations required, the server when the project needs it and the database.

How I use AI (and where I don't)

Development is assisted by AI and large language models (LLMs). They let me generate interface variations, starter code and placeholder content, which lets me iterate on something concrete instead of staying at the idea stage. I choose the technologies for each project according to what it needs; there is no fixed stack.

What I don't delegate: defining which problem is being validated, UX decisions and code review. I review what I deliver and I am accountable for it. An MVP built with AI is still an MVP: it is for learning, not a replacement for a product ready to scale.

How I work

  1. Definition workshop.
  2. Quick flows and wireframes.
  3. AI-assisted build.
  4. Review and polish.
  5. Delivery and test plan.

Frequently asked questions

What is the difference between a prototype and an MVP?

A prototype simulates the experience so it can be tested. An MVP actually works, with the minimum needed for real people to use it.

Is the code useful afterwards?

It depends on how it is built. We discuss it when defining the scope: sometimes it makes sense for it to be disposable.

Do I need to have everything defined?

No. Sorting out the idea is part of the work.

How much does it cost?

It depends on what needs testing and how much the prototype has to work. We start with a 30-minute call about your idea, then I send a proposal with scope, stages and a fixed price.
