AssumptionViability!!5 Critical#pricing

Capture after a meeting, an interview, or a realization. Takes 30 seconds.

You've launched before. You know how this goes.

Someone opens a spreadsheet. Everyone dumps assumptions into it. Then Monday happens — and six months later, the fatal bet was sitting in row 47, untouched since week two.

From hoping to knowing

Without Assumption Mapper
  • Assumptions buried in docs nobody opens
  • Gut feelings you can’t defend in a board meeting
  • That nagging sense you might be building the wrong thing
With Assumption Mapper
  • Every critical bet visible and ranked
  • Evidence connected as you go — from interviews, analytics, experiments
  • The confidence to say: here’s what we’ve tested, here’s what we know

Nothing falls through the cracks

Four views. One system. Everything connected.

Built from the trenches

“After 13 years building ventures across Europe and Greater China, I built the tool I wished I had on every single engagement. Every team I worked with tracked assumptions in spreadsheets — or worse, not at all. This is the system that was missing.”
