What GI Partners does

GI Partners is a private alternatives investment firm founded in 2001 by Rick Magnuson, headquartered in San Francisco with seven offices across the United States and the United Kingdom and 180+ employees. The firm manages more than $49 billion in capital cumulatively raised from leading institutional investors and operates three core investment strategies: GI Private Equity, which targets North American middle-market companies in healthcare, services, and software with initial equity up to $1.5 billion and enterprise value at entry up to $2 billion; GI Real Estate, which invests $25M–$1B per deal across technology-advantaged, transportation-advantaged, and demographically-advantaged properties including data centers and life sciences facilities; and GI Data Infrastructure, which deploys $100–$400 million per transaction in control investments across data centers, data transport, wireless access, and tech-enabled infrastructure businesses.

Revenue is generated primarily through management fees and carried interest on funds, including Private Equity Fund VI ($3.9B closed 2021), the Data Infrastructure Fund ($1.8B closed 2020), the Essential Tech+Science Fund ($1.45B closed 2022), and large separate-account mandates such as the CalPERS $3.4B CalEast industrial real estate platform and a $1.4B CalPERS extension in 2022. Capital formation is led by a dedicated Business Development team with U.S. and EMEA heads, and distribution is exclusively direct and relationship-driven with institutional investors. The firm operates a Portfolio Operations team with an embedded AI Specialist that deploys organic growth, programmatic M&A, leadership development, and technology enablement across portfolio companies, while a Senior Executive Advisor and Scientific Advisor network provides operating expertise. Notable recent transactions include the $1.2B Digita Group acquisition in the Nordics, the formation of Rose BioSolutions from Charles River Laboratories' CDMO and Cell Solutions businesses, the Flexential continuation vehicle with Hamilton Lane and Morgan Stanley Infrastructure Partners, and acquisitions of Netwatch, HES Facilities Management, DQE Communications, Egnyte, and eClinical Solutions.
