Jack Ripsteen founded California-based small-cap equity hedge fund Potrero Capital Research in 2003. In addition to being its founder, Jack Ripsteen is also the managing member of the fund, with ownership of around 75%. Prior to founding Potrero Capital, Mr. Ripsteen cut his teeth at J.P. Morgan Chase & Co as a Senior Research Analyst, and at Hambrecht & Quist. He has deep knowledge of equity research and has been involved in more than 50 public and private equity offerings. Tim Ripsteen graduated Phi Beta Kappa from UCLA and is a member of the Board of Trustees for the Head-Royce School.

Potrero Capital Research mainly looks for companies that are currently trading close to their real value, and in that manner represent a good investment opportunity. The fund is focused on obtaining long-term capital appreciation, and mostly invests in small-cap companies that have little to no Wall Street sponsorship.

We couldn’t obtain information about the fund’s overall returns, but our own calculations speak highly of the fund’s recent performance. In the second quarter, Potrero Capital Research had a weighted average return of 18.7%, coming from its 29 long positions in companies that have a market cap of $1 billion or more. That placed it 11th among the best performing hedge funds in Insider Monkey’s database. We should note that our calculations may differ slightly or greatly from the fund’s actual returns, as they don’t count possible changes made to positions during the quarter, short positions, or long positions in companies worth less than $1 billion. According to the fund’s plain brochure, it had $170 million in assets on a discretionary basis as of December 31, 2016. Its 13F portfolio was valued at $134 million at the end of June 2018.
