Financial Services San Francisco, California 51–200 employees Founded 2015 Privately Held

Finix operates a payment processing platform with a mobile-first tech footprint (Android, Swift, Kotlin, React) and an API-driven integration layer. Active development spans SDKs, embeddable payment components, and dashboard tooling, with recent focus on iOS transaction support and compliance automation. The hiring mix is sales-heavy relative to engineering—7 sales roles against 4 engineering—and skewed toward senior talent (12 of 18 open roles), pointing to a revenue-acceleration phase rather than platform expansion.
