  • The DOJ investigation has been ongoing for almost a year.

DOJ Probe Initiated

The Department of Justice (DOJ) has begun an investigation into Andreessen Horowitz (a16z) regarding its partners' roles on the boards of Databricks and Fivetran. This probe, which has been ongoing for nearly a year, centers on whether these board positions violate antitrust regulations.

Conflict of Interest Concerns

Ben Horowitz, a16z co-founder, serves on the Databricks board, while partner Martin Casado is on the Fivetran board. Although Databricks and Fivetran were not direct competitors when a16z initially invested, Databricks' expansion into AI data pipelines and application connectors with its Lakeflow product now places it in direct competition with Fivetran's core business. Holding board seats in competing companies raises conflict of interest concerns, as directors have access to sensitive strategic information.

Legal Basis and Industry Reaction

The investigation cites Section 8 of the Clayton Act, a 112-year-old law that prohibits individuals from serving on the boards of competing companies. This law has rarely been applied to venture capital firms, making the current probe a significant event for the industry. Several venture capitalists have expressed surprise at the DOJ's focus on this issue.

Potential Implications for Venture Capital

The outcome of this investigation could have broad implications for the venture capital industry. If a16z is compelled to relinquish a board seat, it might reduce the perceived value of board commitments from top-tier VCs, as investors could be forced to step down if portfolio companies evolve into competitors. While a 'Chinese wall' could theoretically separate the partners, the legal precedent set by this probe is being closely watched.
