The DOJ is investigating a16z. What does this mean for venture capital?

The Department of Justice has been examining Andreessen Horowitz for close to twelve months concerning board seats held by partners Ben Horowitz, who sits on Databricks’ board, and Martin Casado, who serves on Fivetran’s board. The inquiry is based on a 1912 antitrust provision that is rarely invoked against venture capital firms. The probe reportedly began in early 2023 and has involved requests for internal communications and board meeting minutes.

When a16z originally backed Databricks and Fivetran, the two companies operated in distinct niches. Over time, each has broadened its product suite into data‑integration and analytics domains that now intersect, creating potential competitive tension. The DOJ’s review raises the question of how venture firms should oversee board membership when the market boundaries of their portfolio companies evolve.

• The investigation centers on alleged interlocking directorates that may limit competition.
• Both Databricks and Fivetran have expanded into overlapping data‑management services.
• The case tests the applicability of early‑20th‑century antitrust law to modern VC structures.

Why this matters

Source facts indicate that the DOJ is applying a century‑old antitrust statute to examine VC board interlocks, a practice that has historically attracted little regulatory attention. From this, one can infer that the agency may be signaling a broader willingness to scrutinize venture capital governance as portfolio companies increasingly encroach on each other’s markets, potentially prompting VCs to adopt more rigorous conflict‑of‑interest policies and board‑seat oversight mechanisms. This shift could alter how firms allocate governance resources and influence the structuring of future investments.
