It manages the day-to-day life of residential mortgages - collecting payments, running escrow, handling modifications and hardship relief - and offers third-party subservicing to investors and lenders. Authorized to service in all 50 states, the District of Columbia and the U.S. Virgin Islands, RoundPoint became a wholly owned subsidiary of Two Harbors Investment Corp. (NYSE: TWO) in 2023.

William 'Bill' Greenberg is a theoretical-physicist-turned-financier who runs Two Harbors Investment Corp (rebranded 'Two'), the mortgage REIT whose in-house servicing engine is RoundPoint Mortgage Servicing LLC. He holds a PhD in theoretical nuclear physics and has spent 25+ years managing structured-finance portfolios at Natixis, UBS and the Swiss National Bank's StabFund before joining Two Harbors in 2012 and becoming CEO in 2020. He pushed the company to bring mortgage servicing in-house by acquiring RoundPoint in 2023, then steered the firm through a high-profile 2025-2026 takeover battle that ended with UWM Holdings agreeing to buy the company.
