Analysis
Greenbelt Capital Partners expands its leadership bench, signaling heightened focus on portfolio value creation within the energy transition landscape.
New joiners include Katie Kiersey, appointed as Chief of Strategy and Operating Partner and head of a newly formed Value Optimization team; Erika Mapes, Managing Director; Austin Major, Principal; and Elouise Roche, Vice President. These hires reflect Greenbelt’s commitment to accelerating portfolio performance as it deploys capital from its latest fund.
CEO and Managing Partner Chris Manning welcomed the quartet, noting that they bring decades of senior operating and investing experience to bear on portfolio companies with a focus on strategic redirection, commercial acceleration, and operational discipline.
Backgrounds for the new leaders span premier global and private equity ecosystems: Kiersey previously led private equity diligence and value creation efforts at Bain & Company, Mapes arrived from Onex Partners and Oaktree Capital Management, Major previously held roles at Blackstone and Vista Equity Partners, and Roche comes with credits from Goldman Sachs Private Equity. Their combined expertise broadens Greenbelt’s capabilities across energy infrastructure, electrification, and industrials transformations.
Greenbelt has stood out in the New Energy Economy, with approximately $3 billion in assets under management and a history of deploying capital across middle-market platforms that enable resilient, carbon-conscious growth. The firm’s senior leadership has collectively committed roughly $6 billion of equity to portfolio companies and has orchestrated more than $70 billion of M&A and financings across over 260 transactions.
The timing aligns with a broader industry cadence: private equity firms are intensifying value creation programs for energy transition investments, aiming to de-risk portfolios through operational improvements, commercial acceleration, and governance enhancements. Greenbelt’s Value Optimization initiative is designed to translate strategic plans into measurable performance gains, positioning portfolio companies to navigate grid modernization, demand growth, and decarbonization pressures more effectively.
