Oak Investment Partners Splits by Sector

Oak HC/FT grew out of Oak Investment Partners, a venture capital firm founded in 1978. In March 2014, while investing its thirteenth fund, Oak Investment Partners announced a restructuring: its healthcare and financial technology investors and its IT investors would each raise their own dedicated funds, with no shared back-office services and no further generalist funds, while both would continue managing the existing portfolio. Oak’s most recent fund had targeted $1.5 billion but closed on less than $800 million, with about 25 percent allocated to healthcare and financial technology.⁠[1][2][2][2][2][2][2]

Oak HC/FT was established by the leaders of Oak Investment Partners’ healthcare and fintech team as part of Oak’s strategy to develop sector-specific funds. The team’s prior Oak investments included athenahealth, Benefitfocus, Castlight Health, NetSpend, Argus Information & Advisory Services, iHealth Technologies, and PharMEDium, with a record of 20 realizations, four IPOs, and six companies valued at more than $1 billion.⁠[3][3][3][3]
