Greenhill Capital Advisory

Robert H. Niehaus makes all investment decisions as Chairman. He was a founding partner of Greenhill & Co., the independent investment bank, and spent over 20 years there building its private equity advisory and commercial services practices. He operates through a lean team with no formal investment committee disclosures.

Robert Niehaus was a founding partner of Greenhill & Co. in 1996 and served as a Vice Chairman until his departure. Greenhill Capital Advisory is an entirely separate entity established by Niehaus in 2009 and has no ownership or operational ties to the publicly traded advisory firm.

No. The firm does not raise traditional blind-pool private equity funds. It structures investments on a deal-by-deal basis through special-purpose vehicles, sourcing capital from Niehaus's personal assets and a network of co-investors including former Greenhill partners and family offices.

The firm targets control-oriented equity investments in middle-market companies, typically in North America. Specific check-size ranges are not publicly disclosed, but the focus is on companies where proprietary origination and an active governance role can drive operational returns rather than financial engineering.

The three stated verticals are business services, infrastructure and energy transition, and financial services. Within energy transition, the firm has demonstrated interest in gas-fired power generation and related mid-market infrastructure assets.
