I've seen too many freelancers, founders, and office managers lose sleep over unpaid invoices. Or worse, damage client relationships just trying to get paid. After 10+ years building software for others, I decided to tackle this one myself.

That's why I'm building Yetty.

I spent 3 years at Gravitee, working on their core API Management platform.
