Get ListedWhite Space Signal is a subscription research platform that ranks two parallel frontiers: ventures worth creating (BUILD) and existing business categories worth acquiring (BUY), both filtered through the lens of advancing AI capability. Each dossier carries three independent scores — Opportunity Quality, Conviction and remaining White Space — letting an operator separate an attractive market from the strength of the evidence behind it.
Candidates start as observed shifts in technology, regulation, procurement or infrastructure. The team then works forward to the constraint each shift creates, asking whether a real buyer with a real budget exists. Ideas are actively rejected rather than collected: duplicates merge, weak cases drop out, and survivors are challenged against incumbent bundling, current competitors and a plausibly stronger AI.
BUILD runs an 18-factor model; BUY runs 20, reflecting the different economics of launching versus acquiring. The public White Space Atlas plots the field, with colour showing remaining White Space, position showing AI compounding against commercial quality, and orb size reflecting conviction.
The current #1 BUILD and #1 BUY reports are published in full without signup. The membership costs $59 per month and unlocks both Top 10s, the Emerging sets, the Atlas, NOW, DECIDE, the Catalyst / Risk Clock, watch functionality and a dated historical track record.
