DOJ's a16z investigation puzzles venture capitalists

The Department of Justice has been investigating venture firm Andreessen Horowitz (a16z) for holding board seats at rival AI companies, Bloomberg reported, a probe that has reportedly been underway for nearly a year. Venture capitalists told TechCrunch they were baffled by the news; on TechCrunch’s Equity podcast, co-host Kirsten Korosec questioned why board-seat conflicts would rise to the top of the DOJ’s priorities at all.

At issue are board seats held by a16z figures at companies that have become competitors as they moved into AI: general partner Ben Horowitz sits on the board of Databricks, and partner Martin Casado sits on the board of Fivetran. Conflict-of-interest rules around competing board seats exist but are not typically enforced closely, according to Equity co-host Anthony Ha, who previously worked at an early-stage VC firm; startups often evolve into competitors of companies a firm already backs as they pivot into a hot sector like AI.

The investigation reportedly began under the Trump administration, with which a16z’s leadership has close ties — the firm’s principals have sat on administration councils. That makes the firm’s public silence notable: Equity co-host Sean O’Kane pointed out that a16z was vocal about policy changes affecting crypto during the Biden administration but has said little publicly about the DOJ probe.

The length of the investigation struck the hosts as unusual for a matter that, on its face, could simply be resolved by asking the firm to give up specific board seats. Panelists speculated that the DOJ could be using a16z, one of the industry’s largest firms, to set an example other venture firms would then follow, or that a longer, slower process reflects internal DOJ dynamics rather than the scale of the underlying issue — though they cautioned that neither is confirmed.

The panel noted that the Trump-era DOJ and SEC have both said prosecuting public companies isn’t a priority, preferring to pursue individuals instead — a shift they said made the length and target of the a16z probe even harder to explain, given the firm’s political proximity to the administration.

Why it matters

If the DOJ is treating VC board-seat conflicts as an antitrust priority even against an administration-friendly firm, other venture firms with overlapping AI board seats may need to reassess exposure regardless of political alignment.
