About Stonepeak

Stonepeak is a New York based infrastructure investment firm that has positioned itself as a thematic investor across digital infrastructure, transport and logistics, and energy transition sectors. Founded in 2011, the firm manages capital on behalf of institutional investors and operates through a portfolio of holdings rather than as a direct data center operator, distinguishing it from traditional facility owners.

The company's approach to digital infrastructure differs fundamentally from pure play data center operators. Rather than building and managing individual facilities, Stonepeak acquires controlling stakes in established operators and platform companies, providing both capital and operational expertise to drive consolidation and optimization. This strategy has resulted in a diverse portfolio spanning over 60 countries, with AGP serving as its primary data center vehicle alongside tower operator Vertical Bridge and other infrastructure assets.

The firm targets enterprise, hyperscale, and government customers primarily across North America, Europe, and Asia Pacific markets. Its infrastructure investment model creates flexibility to pursue opportunities across segments, whether through platform consolidation, technology modernization, or geographic expansion. With 190 employees operating globally, Stonepeak functions as a capital allocator and operational partner rather than a facility-focused operator, competing indirectly with larger regional and global data center companies through its portfolio companies. This structure positions the firm to benefit from infrastructure sector consolidation trends while maintaining diversification across digital and energy infrastructure.

Stonepeak is a leading alternative investment firm specializing in infrastructure and real assets, including investments in digital infrastructure relevant to data centers, telecom, cloud computing, and AI sectors.
