San Francisco-based hedge fund SoMa Equity Partners is winding down after returning capital to investors, bringing the curtain down on a technology-focused equity manager that once oversaw more than $4bn in assets, according to a report by Business Insider.

The report cites regulatory findings and unnamed people familiar with the matter as revealing that the firm, founded in 2016 and led by former Apex Capital chief investment officer Gil Simon, was managing around $2bn before deciding to close,.

The reasons for the shutdown have not been disclosed, although Simon appeared to confirm the end of the firm in a LinkedIn post, describing it as the “end of an era” while thanking SoMa’s employees, investors, partners and other supporters.

SoMa and Simon had reportedly not responded to requests for comment at the time of publication.

The manager built its investment strategy around technology companies, with its San Francisco base providing what it described as a geographical and philosophical advantage in identifying opportunities across the sector.

Regulatory filings have shown SoMa holding significant positions in some of the world’s largest technology companies, including Nvidia, Amazon and Alphabet.

The hedge fund’s assets had declined substantially from their 2021 peak of more than $4bn, filings indicate. Among its investors at various points were the foundation of Google co-founder Larry Page and Citigroup’s corporate pension, according to data from institutional-investor research provider Old Well Labs.
