About Us

Pursuit of truth in credit.

We strive to be the preferred partner to lending platforms, providing not only access to capital but also underwriting technology capabilities to allow innovative lending platforms to grow their business. 

Our firm is made up of 60+ professionals working in San Mateo (HQ) and New York, working in-office on Tuesdays and Thursdays. We are passionate, hard-working, relentlessly-resourceful, impact-focused individuals.

The Role

    • Move us from our Jenkins based CI/CD to GitHub actions or similar

  • Security

    • Design and implement access management strategy for both human and machine resources following the principle of least privilege
