The payment model for professional services work is broken in two predictable ways. Upfront retainers give the service provider no incentive to deliver on time, because they've already been paid. Time-and-materials billing misaligns the client's interest in efficiency with the provider's interest in hours billed. Both models create adversarial incentives that add friction to every milestone.
Milestone-based escrow solves both problems simultaneously. The total contract value is locked in escrow at signing — so the client knows the funds are committed and the provider knows they'll be paid. Funds are released only when both parties approve a milestone. The platform's fee is deducted at release, so the platform earns only when work is approved. Everyone's incentives point in the same direction.
How it works technically
Stripe Connect handles all escrow mechanics on GameChangers. When a contract is signed by both parties, the agreed contract value is held in a Stripe-managed escrow account. When a milestone is submitted by the provider and approved by the client, the milestone value minus the platform fee is released to the provider's connected bank account within 7 business days.
The audit trail captures every submission, every approval, every dispute, every release — with IP address and timestamp on each action. In the event of a dispute, the full audit trail is available to both parties and, if necessary, to legal counsel.
What changes about the risk profile
For mission leads, escrow eliminates the risk of non-delivery after payment. For professionals, it eliminates the risk of non-payment after delivery. For the platform, it makes every transaction verifiable and auditable — which is a compliance requirement for programs operating under DFARS or ITAR.
For underfunded programs and independent specialists, this is the mechanism that makes participation viable. A researcher at an early-stage organization doesn't need to invoice and wait 60 days. A defense program doesn't need to set up a contract vehicle for every independent specialist. The escrow system handles both sides of the trust gap.
