Built different

Real signals, not vibes

Every gap is sourced from a real builder post, GitHub issue, or product review — never invented. Click any source chip to verify.

Transparent scoring

Our 5-signal model (Pain · Demand · Supply · Trigger · Pay) is open. See exactly why each gap ranked where it did.

Early, not late

Surface opportunities before mainstream coverage arrives. Build on the trend, not after.

STEP 2

Each gap is graded on 5 signals — pain, demand, supply, trigger, willingness to pay — and ranked by build likelihood.

STEP 3
