How it works

Three layers between you and the noise.

We surface founders the tier-1 funds never see, do the verification work, ship a memo. You read it on the train.

01

Hunt where they don't.

Indie Hackers, MicroAcquire, App Store new launches in emerging markets, niche industry forums, regional X / LinkedIn signal. Not YC batches. Not "exited stealth today" PR loops.

02

Verify what's real.

Domain age (Wayback), GitHub 90-day shipping cadence, App Store ratings, competitor funding, regulatory landscape, three citations per claim. Numbers over vibes.

03

Ship the memo.

One dossier per vertical per day, branded PDF. Investor memo template, not a marketing tear-sheet. Read in 6 minutes.

Active verticals

Pick the lens you're hunting through.

Each vertical has its own sourcing rules, scoring rubric and editorial team. Subscribe to one, several, or all.

Five tiers. You pick how wide you hunt.
