# Online Payment Platform (OPP)

> OPP provides embedded payment infrastructure for online marketplaces and platforms. We handle merchant onboarding and KYC, end-to-end payment flows, split payments, escrow, payouts, and buyer/seller support, so platforms can monetise transactions without becoming a regulated payment institution themselves. Founded in 2013, headquartered in Delft, the Netherlands, serving platforms across Europe.
