One Stone Energy Partners

The firm invests in the energy sector through three transaction types: growth equity for expanding companies, private investment in public equity (PIPE) for listed businesses seeking discrete capital, and recapitalizations for restructuring existing balance sheets. This multi-tool approach allows One Stone to deploy capital across private and public markets, which is relatively uncommon among small and mid-sized energy specialists.

Public records do not indicate a formal blind-pool fund structure. The firm's minimal digital footprint and focused strategy are consistent with a deal-by-deal or independent-sponsor model, where capital is raised on a transaction basis from co-investors and limited partners sourced through the principals' personal networks.

The firm's Miami headquarters positions it for energy deal flow across the US Gulf Coast and Latin America. Given the firm's sector concentration, deal origination likely flows through specialized energy investment banks, regional operators, and service-company relationships rather than broad auction processes.

Most energy private equity funds specialize in a single transaction type — typically control buyouts or early-stage venture. One Stone's mandate spans growth equity, PIPE, and recapitalization in one vehicle, allowing it to pivot between private and public market opportunities and serve as both a minority and structured capital provider depending on the cycle.

The firm's formal strategy documents do not explicitly separate renewable from conventional energy. The three deal-structure pillars — growth, PIPE, and recap — are applicable across upstream, midstream, downstream, oilfield services, and energy transition verticals. Actual portfolio weights have not been publicly disclosed.
