Tailwise — prototype to fundraising-ready demo

Founding-engineer prototype work with a clear outcome: a demo that made fundraising real.

2017–2018 Helped close ~$200K in pre-seed funding.

Context

  • Early-stage startup with an idea that needed to become a working product quickly.
  • The goal was a demo that could survive real conversations—without hand-wavy "we'll build it later."

What shipped

  • A working prototype that proved the core flow.
  • The boring essentials so it was usable: basic reliability, a clear user path, and the ability to iterate fast.

Outcome

  • The prototype helped close ~$200K in pre-seed funding.

What made it work

  • Tight scope: one core flow, not "the whole product."
  • Fast iteration using real feedback (not assumptions).
  • Pragmatic engineering choices so the prototype wasn't a dead end.
