The problem

60 million workers.
Zero financial infrastructure.

01
Payment delays
Freelancers wait 24-48 hours for batch-processed payouts. The work is real-time. The payment is not.
02
Cross-border fees
Up to 8.78% lost on international payments before it reaches the worker. Compounding across every invoice.
03
No financial history
Years of completed work lives in inboxes and chat threads. Invisible to banks, credit systems, and future clients.
04
Client payment risk
Clients can ghost after delivery. There is no escrow layer. No protection. No recourse.
The Stablelane answer

Circle products at every layer.
