We are Rithm

An asset manager focused on real estate and financial services.

Delivering over 10 years of strong and stable results

We were founded in 2013 under Fortress Investment Group to capitalize on a compelling investment opportunity in mortgage servicing rights (MSR). What was once solely a manager of MSRs, Rithm has grown into an investment platform with a diverse and opportunistic portfolio across the real estate and financial services sectors. Our portfolio of investments and operating companies has a successful track record of performing across changing economic environments.

Exceptional operational expertise

Over time, we’ve developed scalable asset manufacturing capabilities with the addition of companies like Newrez, Genesis Capital, and others. This ecosystem of closely managed operating companies allows us to better source, acquire, securitize, and manage assets—capturing long-term value and market insights for a competitive advantage.

Redefining the manager-to-investor relationship

We believe success is defined by the strength of our relationships. Only through the collaboration found in more bespoke, nimbler environments, can we capitalize on a dynamic, continuously evolving market. We bring an exceptional level of transparency and access to our investment partnerships—which we think is critical to driving superior results.

Welcoming a new era of company growth

In 2023, Rithm acquired Sculptor Capital Management, a leading global alternative asset manager with $33bn in AUM. Sculptor is built to capitalize on a wide spectrum of market opportunities through deep expertise, swift action and an open, best idea culture. Sculptor focuses on corporate and structure credit, real estate and manages an opportunistic multi-strategy hedge fund. With more than 70% of its client partnerships exceeding a decade, Sculptor is well aligned with our foundational principle of “the power of partnership."
