Fully working prototypes within 2–3 days

Validate your idea and your business model before you commit a budget to it. Real software, real feedback, real fast.

01 / how it works

From idea to evidence in three days

Day 0 — Sharpen the idea

A focused call to cut your idea down to the one thing worth validating. We define what “working” means before anything is built.

Day 1–2 — Build

AI-first development with a senior engineer’s judgment: a fully working prototype, not a clickable mockup.

Day 3 — Validate

You put it in front of real users or stakeholders. We iterate on what the feedback actually says — or you walk away having spent days, not months.

02 / why it works

Prototypes beat pitch decks

A prototype answers the questions a slide deck can only speculate about: will users get it, will they use it, will anyone pay for it. An AI-first approach makes this affordable — twenty years of engineering experience make it reliable.

And because it’s real software, a successful prototype is a head start, not a throwaway: the learnings (and often the code) carry directly into the actual product.

03 / proof

A recent example

A habit-building Lovable prototype I use daily with a few friends — built Lovable-only, with a fully working Supabase backend behind it.

Have an idea worth testing?

Tell me about it. If it can be validated in three days, we’ll do exactly that.
