The funds will be used to provide investment to CIC's portfolio of technology businesses developed by the University of Cambridge and the wider Cambridge cluster, Europe's largest technology hub.
CIC launched in 2013 to provide growth capital to local tech businesses providing long term capital to support the sustained growth of investee companies.
A team at Pinsent Masons was led by corporate partner Russell Booker, assisted by corporate associate James Kaye.
Commenting on the deal Booker said: "This fundraising will be transformational for CIC and for the businesses it invests in. There has been a significant increase of new tech-based investment opportunities signalling a healthy pipeline of opportunities for CIC. We are delighted to have played a significant role in ensuring this valuable work continues."
