Outcome

Whop automates their $5.4B/yr back office with FRAGMENT

Problem

To build and run an internet business via API, Whop needs a back office that bills, collects and accounts for payments as they’re made.

Solution

With FRAGMENT all of Whop’s financial events live in one unified system.

Coding agents read and inspect existing entry patterns, propose and validate new financial flows and iterate until the money movement balances. If a developer wants to add a new fee, payout, balance, or restriction, the agent can author the flow — and FRAGMENT enforces whether it is financially correct.

Most of our code now is agentically built. If there’s a clear pattern established, the agent can conform to it with no human involvement.

Whop extends FRAGMENT’s correctness guarantees from engineering into finance operations: agents read from FRAGMENT to detect reconciliation discrepancies, investigate anomalies, automate month-end close, and generate accurate reporting.

FRAGMENT helps our agents navigate complex money flows. Agents propose and test payment flows, investigate anomalies, and run reconciliation and close workflows against it.
