Financial Services San Francisco, California 51–200 employees Founded 2015 Privately Held
finix.com LinkedIn

Finix operates a payment processing platform targeting software platforms, marketplaces, and mid-market businesses. The tech stack is frontend-heavy (React, Redux, TypeScript) with native mobile support (iOS/Android/Kotlin) and cloud infrastructure (AWS, Kubernetes), suggesting a product-centric rather than enterprise-integrations-first approach. Sales hiring outpaces engineering 4.5:1, and active projects focus on sales playbooks, partnership distribution, and payment dashboards — positioning Finix as sales-driven while building out product infrastructure to support scale.
