Biro is a P2P marketplace for late-stage private company shares. Every participant is verified. Every order is real. Gecko — our AI layer — filters intent and qualifies matches before you ever speak to a counterparty.
Every verified participant sees the number of bids and asks on each company. No prices. No sizes. No names. Just a signal that the market exists — and how active it is.
Register your interest — buy or sell, size, structure. Instantly unlock the volume and structure of counterparty orders. Price is optional — disclosed only when both sides agree.
Click Match and Gecko — our AI navigator — asks both sides a short series of questions. Timeline, structure, capital readiness. Only compatible mandates proceed. One bad match = a flag on your account.
Once Gecko confirms compatibility, you see each other's profile — type of fund, AUM tier, jurisdiction. Names are revealed only by mutual consent. You can request an NDA before proceeding further.
Gecko is not a broker. It has no interest in closing your deal. It is a filter — trained to ask the right questions, match compatible mandates, and protect every participant's time.
