# Economic Model & Fee Structure

Sigma3 aligns revenue with verified performance.

* **Performance-Based Fees:** GPT360 earns only after successful milestone completion.
* **No Fees on Failed Rounds:** Refunds cancel all platform charges.
* **Provider Coordination Fees:** Paid externally by partners, not from escrow.
* **Transparency:** Each campaign displays full fee breakdown (platform % + provider costs).

This ensures GPT360 profits only when verified projects succeed.
