Frequently asked questions
Who runs investment decisions at Ursula Management?
Jonathan Sobel, the firm's managing partner, makes investment decisions. Sobel was a partner at Goldman Sachs prior to founding the family office in 2008 and brings nearly four decades of experience across fixed income, mortgage trading, and risk management. The office does not publicly list other investment professionals, indicating a lean, principal-led structure.
How does Ursula Management source its real estate investments?
The firm primarily engages in direct origination and senior mortgage lending rather than bidding on widely marketed assets. Sobel's deep network from Goldman Sachs and his board roles at Jackson National Life Insurance and Prudential plc provide proprietary deal flow, particularly in structured-credit and income-producing real estate. The office likely co-invests alongside former Goldman colleagues and boutique operators known to the principal.
Does Ursula Management operate more like a venture firm or a traditional family office?
Ursula Management operates as a traditional single-family office, allocating across asset classes rather than raising external funds. While venture capital is one component of the portfolio, the firm is not structured as a venture fund — it makes direct investments using the Sobel family's permanent capital. No evidence exists of outside limited partners or a fee-generating management company.
How is Ursula Management's investment approach different from a typical multi-family office?
Ursula Management manages capital for a single principal, not multiple families. This creates complete alignment — no investment committee negotiations, no client-reporting overhead, and the ability to hold illiquid assets through market cycles without redemption pressure. The office leverages Sobel's fixed-income and risk-management background to structure bespoke credit and real estate transactions that would be difficult for a consensus-driven MFO to underwrite.
Where does the underlying wealth come from?
The wealth was generated by Jonathan Sobel's career at Goldman Sachs, where he was a partner until 2008. Sobel held senior roles in mortgage trading and risk management during a period of significant value creation at the firm. The family office was capitalized with the proceeds of that partnership, making it a Wall Street-origin single-family office.
