Bedrock Capital

Bedrock Capital is a venture firm associated with Geoff Lewis, whom TechCrunch calls its founder. We did not find the firm's own website, and no page we read states its stage, sector focus or typical check size. The domain bedrockcapital.co is a different business: it describes itself as a consultancy for managers of private equity, real estate and venture capital funds.^[1],[2]

A note on identity. The SEC filings below name the issuers Bedrock Capital I, II and III and an Entrepreneurs Fund II, and list Geoff Lewis Tabachnick and Eric Stromberg as managing members of the general partner. TechCrunch calls Geoff Lewis the founder of Bedrock Capital. No page we opened says outright that the filings belong to Lewis's firm. The match rests on the name and the fund names, so treat the link as likely but unconfirmed.^{[3],[4],[5],[6],[1]}

The earliest filing we found is for Bedrock Capital I, LP, organized in Delaware in 2017 with a first sale dated 6 November 2017, together with a parallel vehicle. Its principal address is in New York. Bedrock Capital II, LP and Bedrock Capital Entrepreneurs Fund II, LP were organized in 2019 and give a different New York address, and the 2021 filing for Bedrock Capital III, LP gives an address in Plainview, New York. TechCrunch reports that Lewis led the Series A of the defense company Mach Industries a few months after its June 2023 seed round.^{[3],[4],[6],[5],[1]}

Geoff Lewis is the person TechCrunch names as Bedrock's founder. The Form D filings list Geoff Lewis Tabachnick (written Geoffrey Lewis in the Fund III filing) and Eric Stromberg as managing members of the general partner. The Fund I filing names Bedrock Capital GP, LLC as the general partner and Bedrock Fund Management, LLC as the management company. No other partners, staff or biographies appear on the pages we read.^{[1],[3],[4],[5]}

Mach Industries is the one investment we can document. TechCrunch reports that Lewis led Mach's $79 million Series A. In June 2025 he joined Keith Rabois of Khosla Ventures to lead a $100 million round at a $470 million valuation, with Sequoia also participating, which TechCrunch said brought Mach's total raised to about $185 million. In September 2026 TechCrunch listed Bedrock Capital among the investors in both tranches of Mach's Series C, a $300 million round at a $1.8 billion valuation and a $600 million extension that raised the valuation to $3.7 billion, alongside Ribbit Capital, Infinite Capital and Sequoia.^[1],[7]

Neither article says how much Bedrock itself put into any of these rounds. Mach makes unmanned military vehicles and weapons, including vertical-takeoff drones, long-range strike systems and counter-drone systems. No other portfolio company is confirmed here, so this is not a full portfolio list, and we found no exits.^[7]
