01 — Challenge

Eight weeks of runway left to prove the product before the next raise.

The founding team had a strong thesis and no working product — every week spent building the wrong feature was a week closer to running out of cash.

Previous attempts at an MVP had sprawled into a half-built platform instead of a testable core loop.

02 — Approach

PHASE 01 Discover Scoped the smallest version of the product that could actually test the core thesis.

PHASE 02 Design A design system built to scale past the first hire, not just the demo.

PHASE 03 Build Shipped the core loop first, then onboarding and analytics around it.

PHASE 04 Launch Instrumented from day one so growth signal was visible immediately.

03 — Solution

Built for the workflow

Scoped MVP architecture

Built to prove the thesis fast, and to not need a rewrite when it worked.

Design system

Tokens and components that let the team ship new screens without re-deciding basics.

Onboarding flow

Activation designed around the moment the product actually proves its value.

Analytics & growth instrumentation

Every key action tracked from launch, so the team could see what was working, not guess.
