DOJ Probes Andreessen Horowitz Over Competing Board Seats
Original: DOJ’s probe into Andreessen Horowitz over board seats baffles VCs
Why This Matters
This rare DOJ application of antitrust law to VC board seats could reshape how venture firms manage portfolio conflicts.
The U.S. Department of Justice has launched a nearly year-long probe into Andreessen Horowitz (a16z) over partners holding board seats at competing companies Databricks ($190B valuation) and Fivetran, invoking Section 8 of the 112-year-old Clayton Act.
The DOJ is investigating Andreessen Horowitz for potential violations of Section 8 of the Clayton Act, which bars individuals or entities from serving on the boards of competing companies. The probe focuses on co-founder Ben Horowitz's board seat at Databricks and partner Martin Casado's seat at Fivetran, which merged with dbt Labs in June. Databricks, valued at $190 billion, expanded into AI data pipelines via its Lakeflow product — directly competing with Fivetran's core business. Multiple VCs told TechCrunch the investigation surprised them, noting the two companies were not competitors when a16z originally invested. One potential resolution is a 'Chinese wall' between Horowitz and Casado to prevent sharing of confidential information, rather than surrendering a board seat. Because regulators have rarely applied the Clayton Act to venture capital, the industry is watching the case closely. If a16z is forced to relinquish a seat, founders may devalue board commitments from top-tier VCs, fearing future portfolio conflicts could trigger similar exits. Andreessen Horowitz, Databricks, and the DOJ all declined to comment.
