Pattern 01
Which hypothesis types your team gets right
Pricing changes? Onboarding tweaks? New surface launches? See the shapes of bets your team is actually calibrated on — and the ones it isn’t.
For product teams that ship to learn, not to look busy
The shipping discipline behind product teams
that actually learn.
Every product decision your team makes — scored, searchable, and impossible to forget. Write the hypothesis before you ship. Score it after. Together.

Your team’s calibration at a glance — built from the same hypotheses you’d already write before shipping.
What you’ll know after 30 hypotheses
One quarter of structured predictions and your team has answers it couldn’t get any other way.
Pattern 02
Where confidence and outcome diverge
Spot systematic over-confidence and under-confidence by PM, by tag, by quarter. The blind spots show up before they become expensive.
Pattern 03
Who tends to be early, late, or right
Mechanical scoring — no manager override anywhere. The data tells you who’s actually right, not who’s loudest in the room.
A learning library that survives team changes
Every resolved hypothesis becomes a permanent, searchable record. When a PM moves on, their reasoning stays. When a new PM joins, the team’s track record is the onboarding.
- →Search by tag, outcome, confidence band, or product area.
- →Private hypotheses stay private — never surface to team views.
- →Lessons-learned notes attached to every resolution.
The team practice
Three steps. Same loop every time. Calibration emerges from the ritual, not from heroic effort.
- 1
Predict
Before shipping, write a causal-chain hypothesis with a pre-mortem and a confidence rating. Choose from 14 templates or build your own.
- 2
Ship
Build, launch, and let the world push back. The hypothesis sits on the team dashboard, waiting for resolution at the date you set.
- 3
Resolve
Mark each claim Held, Wrong Magnitude, or Broke. The score is mechanical — no override, no rewriting history. Lessons attach to the record.
What a single hypothesis looks like
A four-link causal chain: intervention to outcome, with every step visible.
Stop shipping on vibes.
Your team is making predictions every week. Hypothesis Lab is the only place those predictions become evidence.
