Backed by operators who've scaled the category

Founder advisors from across institutional private markets, anchored by Steffen Pauls, founder of Moonfare.

TrancheBook is building the trust infrastructure that institutional private market research has lacked — calibrated, source-traceable, and built to be wrong in public when it is wrong.

The trust infrastructure

The advantage isn't that we use AI — every competitor will. It's the verification stack around the AI.

We reject deals that don't fit

Every memo passes deterministic kill gates before it ships. An LBO request on a $300B GSIB will be turned down — and the reasoning logged.

Memos carry a public accuracy track record

Every prediction is resolved against eventual reality and published. We are willing to be wrong in public — that's what makes the track record real.

Every claim links to its source

EDGAR filings, S-1s, named news sources, GDELT entries — every assertion in a memo is hyperlinked to its origin. No black-box reasoning.
