DOJ Probes Andreessen Horowitz Over Databricks and Fivetran Board Seats
DOJ probes Andreessen Horowitz board seats at $190 billion Databricks and Fivetran under Clayton Act Section 8, raising VC concerns about future conflicts.
Summary
On August 18, 2026, Bloomberg reported that the Justice Department has spent nearly a year investigating Andreessen Horowitz over seats on competing companies’ boards. The inquiry centers on $190 billion Databricks, where a16z co-founder Ben Horowitz is a director, and Fivetran, whose board includes partner Martin Casado and which combined with dbt Labs in June. An anonymous Databricks investor said the companies were not competitors when a16z invested, but Databricks has moved beyond cloud storage with Lakeflow, an AI data pipeline and application connector product targeting Fivetran’s core market. With hundreds of portfolio companies, a16z can face new overlap as startups pivot or expand.
The DOJ is invoking Section 8 of the 112-year-old Clayton Act, which prohibits an individual or entity from serving on competing companies’ boards. Although backing direct rivals has become more accepted, as VCs investing in both Anthropic and OpenAI show, directors receive sensitive strategy unavailable to ordinary investors, creating sharper conflicts. A partner could resign from one board, while one investor said a Chinese wall could separate Horowitz and Casado because different partners hold the seats. VCs were surprised because regulators have rarely applied Section 8 to venture capital. A forced surrender could weaken founders’ confidence in top-tier VC board commitments that later portfolio overlap may undo. Andreessen Horowitz answered neither TechCrunch nor Bloomberg, while Databricks and the DOJ declined comment.
Positives
- $190 billion Databricks and Fivetran were not competitors when a16z invested, according to an anonymous Databricks investor.
- Ben Horowitz and Martin Casado hold the seats separately, allowing a16z to establish an internal confidentiality wall, one investor said.
- A resignation from one board offers a direct remedy if regulators determine the positions conflict.
- Databricks’ Lakeflow expansion adds AI data pipelines and application connectors to its established cloud storage products.
Risks & concerns
- The DOJ’s nearly yearlong investigation could force Andreessen Horowitz to surrender a Databricks or Fivetran board seat.
- Board directors receive sensitive strategic information, making simultaneous representation of competitors more conflicted than ordinary cross investment.
- Databricks’ Lakeflow now enters Fivetran’s core market for AI data pipelines and application connectors.
- A forced exit could reduce how much founders value board commitments from top-tier VCs whose portfolios may later overlap.
- Andreessen Horowitz did not answer TechCrunch or Bloomberg, while Databricks and the DOJ declined comment.
