Petershill Partners

Ali Raissi-Dehkordy and Robert Hamilton Kelly serve as Co-Heads of Petershill Partners, overseeing the acquisition and management of minority equity stakes in alternative investment firms (per the firm's official communications, 2023). They operate within Goldman Sachs Asset Management's broader permanent capital platform, sourcing and evaluating GP-stake opportunities globally.

Petershill sources opportunities through Goldman Sachs' extensive institutional network, building relationships with alternative-asset managers seeking growth capital, succession liquidity, or strategic partnerships. The firm's reputation as a passive minority investor — one that does not interfere with investment decisions or operational management — often places it in competitive processes where founders prioritize non-control transactions.

No. Petershill Partners does not manage commingled LP funds, direct co-investment vehicles, or any product that competes with the general partners in which it invests. Its sole activity is acquiring and holding minority equity stakes in the management companies of alternative investment firms, thereby participating in their fee and earnings streams without operating as a fund manager itself.

Petershill Partners targets established alternative asset managers across private equity, hedge funds, private credit, real assets, and secondaries. The firm seeks platforms with durable franchises, multi-cycle track records, and institutional LP bases. Confirmed portfolio firms include Accel-KKR, Industry Ventures, and Riverstone Holdings — managers that collectively oversee hundreds of billions in LP capital.

Petershill Partners originated as a business unit within Goldman Sachs Asset Management in 2007. In 2021, it listed on the London Stock Exchange as a standalone public company, though Goldman Sachs retained a substantial ownership stake. The firm continues to benefit from Goldman's origination, due diligence, and operational infrastructure while maintaining independent public-company governance.

Petershill Partners generates returns through the fee-related earnings and balance-sheet co-investment income of its portfolio firms. By owning minority GP stakes, it collects a pro-rata share of management fees, carried interest, and investment returns from the funds those GPs manage — creating a diversified income stream that is structurally distinct from direct fund investing.

Petershill Partners exclusively acquires passive, non-voting minority stakes in its investee firms. Founders and management teams retain full operational and investment control. This structure is central to Petershill's value proposition — it appeals to managers who want growth capital or partial liquidity without ceding autonomy over their investment processes or firm culture.
