I turn one product hypothesis into a working prototype you can put in front of users, investors or your team to see if the idea holds up.

Timeline: Scoped per hypothesis, up to 7 working days

Price: $4,000 - $8,000 Optional: presentation demo for investors: $1,000 - $2,000

Founders before a pilot or investor demo, and teams testing a complex feature before committing engineering.

the hypothesis and the one scenario that tests it,

a working, hosted prototype with a shareable link,

a GitHub repo and a Figma file with designs matching the prototype,

a summary of the assumptions behind it, backed by desk research, and what to test with users,

a 1-hour validation workshop with up to 5 people from your team.

Production-ready code, backend and integrations (the demo runs on mock data), new user interviews and usability tests. They can follow as a separate step.

Continue with Design Partner: if testing confirms the idea, I stay with your team through the build and we skip part of the onboarding.
