Primer.io

Primer.io builds a unified payment infrastructure platform intended to let merchants connect any payment provider, optimise transactions and scale internationally without reworking their payment stack. The platform brings payment processors, fraud tools and identity or verification services into a single integration layer, replacing fragmented, provider-by-provider connections with one API-driven system. Work spans payment orchestration, fraud-tool integration, transaction optimisation and broader API and integration-platform engineering.

The company sells to merchants across retail, travel and fintech. Named customers include GetYourGuide, Printify, Maisons du Monde and AppsFlyer. Its stated ambition is an open, interoperable payments ecosystem in which complexity is abstracted away so businesses can concentrate on their own products; the company describes itself as early in that effort.

Primer.io operates with a global geographic remit. Its engineering agenda centres on payment infrastructure, orchestration and optimisation, alongside fraud and verification integrations. Founders include a co-founder, Paul, and a second co-founder who authored the company's platform description.
