PennyMac grew from a crisis-era mortgage buyer into a $731 billion servicing machine. Its next act is more ambitious: turn the software and operating muscle behind that machine into a product for the rest of the industry.

Kastle is a San Francisco startup building AI voice and messaging agents purpose-built for consumer lending, starting with mortgage servicing.

Founded in 2024 by Rishi Choudhary and Nitish Poddar and backed by Y Combinator (S24), Kastle plugs into existing systems of record such as ICE MSP and works with large mortgage servicers, including Carrington Mortgage Services.
Haven is a New York-based mortgage technology company that gives servicers, subservicers, and lenders a white-labeled platform to keep talking to homeowners long after the loan closes. Instead of a relationship that ends at payment collection, Haven layers borrower-intent prediction, prepayment analysis, personalized offers, and financial education on top of existing servicing systems through a single API integration. Its consumer-facing Haven Wallet lets borrowers pay their mortgage and shop home services in one place regardless of who owns the servicing rights, helping lenders boost recapture, retention, and revenue per borrower.
