Theorem

Theorem is a profitable fintech platform that uses machine learning and data science to underwrite and invest in marketplace lending loans, managing a $2B+ portfolio of whole loans and asset-backed securities. The company's core technology — the Theorem Loan Score (TLS) — evaluates default risk at the individual loan level rather than assigning a generic credit score, trained on millions of historical loan records. Backed by Y Combinator and Two Sigma Ventures, Theorem offers partners Custom Loan Integration Programs (CLIP) and Securitization as a Service (SaaS) to help originators expand volume and access capital markets. The company has been operational since 2014 and maintains offices in the Bay Area and New York.
