Proxy

Proxy (Y Combinator, Summer 2016) was a San Francisco digital-identity startup founded by Denis Mars and Simon Ratner that built a mobile and wearable digital wallet for payments, identity, and authentication, later expanding into biometric identity verification and vaccine-credential verification. The company was acquired by OURA in 2023; the proxy.com domain no longer resolves to an active product and there is no public developer platform, API, or documentation surface to enrich. This profile is retained as a historical/acquired-company record.

Proxy is profiled on the APIs.io network. Tagged areas include Company, Digital Identity, Authentication, Wearables, and Access Control.
