Cleantech investment firm SJF Ventures has closed its third fund, raising more than $90 million in capital.

The total outstrips the $75 million target Durham-based SJF set for the fund and more than triples the size of the firm’s $28 million second fund, which is still investing. In March, SJF disclosed in securities filings that investments in the fund had grown to $48 million.

“We are particularly excited that a wide variety of bank, insurance, foundation, family office, pension, mutual fund, and individual investors have recognized that SJF’s impact investing strategy can yield above market financial and mission results,” SJF Managing Director David Kirkpatrick said in a statement.

Investors in SJF’s third fund include banks such as Citi, Deutsche Bank and State Street Bank; the endowments of the Annie E. Casey, F. B. Heron , Jesse Smith Noyes, and Park Foundations and the Wallace Global Fund; insurances and financial services firms MetLife and Prudential Financial, Inc.; mutual and pension funds Calvert Equity Portfolio and MMBB Financial Services.

SJF Ventures invests in “high growth, positive impact companies” seeking expansion capital rounds of $1 million to $10 million. The company has invested in technologies and companies in solar energy, energy efficiency and food safety. In the last ten years, SJF has invested in 36 portfolio companies, such as Troy, N.C.-based Aseptia, a sustainable food processing company; and CleanScapes, a Seattle company that provides sustainable solid waste and recyclables collection.
