Pylon builds enterprise-grade APIs for the mortgage industry, re-wiring every layer of the mortgage stack from capital markets to origination. Its APIs are intended to make mortgages programmatic, accessible and efficient, serving an asset class the company puts at $12 trillion. The firm has raised over $30M, with investors including Peter Thiel, Naval Ravikant and Citi.
The engineering work draws on technical domains uncommon in financial technology: operations research, programming language theory, distributed systems and strong typing. The company describes its product as foundational infrastructure rather than CRUD applications or wrappers around existing models.
Pylon is a small, ambitious engineering team organised around real ownership of systems. It states a preference for first-principles thinking and vigorous technical debate, and sets a standard of craftsmanship in which 'good enough' is not acceptable across code and interface design.
