EarnOS, a platform built on verifiable user engagement, has raised $18.5M from investors including 1kx, Circle Ventures, Coinbase Ventures, and Social Graph Ventures.
The company's platform allows users to connect third-party accounts and complete "missions" – from product demos to social engagement – earning stable-coin rewards. Leveraging zkTLS for verifiability, EarnOS promises brands better unit economics than traditional web2 ad networks, enabling hyper-granular targeting, such as Uber campaigns specifically reaching Doordash power users.
