DOJ Investigates a16z Board Seats at Competing Portfolio Companies
Original: Why is the DOJ investigating Andreessen Horowitz’s board seats?
Why This Matters
The probe signals growing regulatory scrutiny of VC board governance under antitrust law, with broad implications for the venture industry.
The U.S. Department of Justice has been investigating Andreessen Horowitz for nearly a year over two partners — Ben Horowitz at Databricks and Martin Casado at Fivetran — holding board seats at companies that have become competitors, invoking a rarely used 112-year-old antitrust law.
Andreessen Horowitz (a16z) is under DOJ scrutiny for a board seat arrangement involving two of its partners: Ben Horowitz serving on the board of Databricks, and Martin Casado sitting on the board of Fivetran. The two portfolio companies have increasingly moved into each other's markets, raising antitrust concerns under a 112-year-old law that has rarely been applied to venture capital firms. The DOJ investigation has reportedly been ongoing for close to a year. At the time a16z made its initial investments, Databricks and Fivetran were not considered direct competitors, but as both companies expanded their product offerings, the overlap grew. The case highlights a structural challenge facing the venture capital industry: as portfolio companies evolve and their markets converge, firms holding multiple board seats may find themselves in legally and ethically complex territory. TechCrunch's Equity podcast — hosted by Kirsten Korosec, Anthony Ha, and Sean O'Kane — covered the probe and its broader implications for how VC firms manage governance responsibilities across expanding portfolios.
