Private alpha — invite only

FSP is the Flow Signal Protocol for AI agents.

Flow's decision intelligence is in daily use by world-class executives and investors representing $450B+ AUM and operating companies valued at $10T+ in combined market cap. FSP exposes that intelligence as a protocol.

The importance layer for the agent economy.

Modern systems can retrieve information. They cannot reliably determine what matters. FSP exposes Flow's judgment as a protocol — agents query before acting.

Built for agents

MCP-native protocol. Drop-in server shipping to alpha partners.

Calibrated, not generic

Each key is tied to a Flow user. Agents get that user's read.

Falsifiable by design

Every output ships with a counter-signal — what would make it wrong.

Production-grade

The same engine behind Flow's daily briefs.

What an FSP response carries

  • ·The read. What changed, what it means, what the agent should do.
  • ·The timing. Why this matters now and not last week.
  • ·The watch-fors. What to monitor as the situation develops.
  • ·The counter-signal. What would make this judgment wrong.

Approved partners receive

  • API access calibrated to a Flow user
  • Integration documentation and example payloads
  • Direct support during integration
  • Anonymized use-case patterns showing FSP in practice

The frame

DNS resolves where something is.
FSP resolves whether it matters.
