Analysis
The Justice Department has opened an investigation into Andreessen Horowitz over partners sitting on the boards of companies that compete, Bloomberg reported and TechCrunch confirmed Tuesday. The nearly year-long probe focuses on two seats: co-founder Ben Horowitz at Databricks, now valued at $190 billion, and partner Martin Casado at Fivetran, which merged with dbt Labs in June. Pulse has previously covered Andreessen Horowitz's expanding footprint of board seats across the AI infrastructure stack, the same footprint that put this probe in motion. Reuters has separately confirmed the DOJ inquiry is active, citing people familiar with the matter, in its own reporting on the probe.
The overlap is recent and was not there at investment. Databricks built its business on cloud data storage and analytics. Its Lakeflow product pushed the company into AI data pipelines and application connectors -- which is precisely Fivetran's core business. Neither a16z partner joined a competitor's board; the companies grew into each other underneath them.
Why VCs are confused
Several investors told TechCrunch they were surprised the probe exists at all. A firm that has funded hundreds of companies will inevitably see some of them pivot into the same market. Backing direct rivals has become normal in this cycle -- plenty of the same funds hold positions in both OpenAI and Anthropic -- but a board seat is categorically different from a passive position. Directors receive strategic detail, pricing plans, and pipeline data that no non-board investor ever sees.
Section 8 of the Clayton Act, passed in 1914, bars an individual or entity from serving on the boards of competing companies. It has been enforced sporadically and almost never against venture firms; the FTC's most visible modern use was pressuring directors off corporate boards in 2022 and 2023. Applying it to a venture portfolio, where competitive overlap emerges years after the check clears, is a genuinely new posture.
The available remedies
The straightforward fix is for one partner to resign a seat. Because a16z has two different individuals on the two boards, the firm can also erect an internal information barrier between Horowitz and Casado -- one investor suggested that structure to TechCrunch. Whether the DOJ accepts a screen from a single firm with a shared carry pool and a shared partnership meeting is the actual question, and the answer sets the rule for every multi-stage fund with a broad portfolio.
What it does to term sheets
Here is the counterweight to the industry's shrug: even if a16z prevails, the probe's existence changes negotiating behavior. Founders take board seats from top-tier firms partly as a signal of durable commitment. If that commitment can be voided later by a portfolio conflict the founder did not create and cannot control, the seat is worth less. Expect more board-observer structures, more explicit conflict-waiver language in financing documents, and more insistence from founders that a named partner -- not the firm -- carries the obligation.
The enforcement history is thin enough to make prediction hard. The FTC used Section 8 in 2022 and 2023 to push directors off overlapping corporate boards, resolving each matter with resignations rather than litigation, and the DOJ's antitrust division has periodically warned that the statute applies to private funds. What has never happened is a contested Section 8 case against a venture firm where the competitive overlap emerged organically. Whether the DOJ can establish that Databricks and Fivetran are 'competitors' within the meaning of a 1914 statute -- when one is a $190 billion data and AI platform and the other is a data-integration business that just merged with dbt Labs -- is a genuine legal question, not a formality.
There is also a timing element worth flagging: the probe has been running for nearly a year without a public filing. Long, quiet investigations often end in a negotiated resolution rather than a complaint, and the most likely outcome remains a resignation or a documented information barrier. But the mere fact that the DOJ chose venture capital as the venue to test Section 8 -- rather than the public-company boards where it has been enforced before -- is what has the industry's attention.
Andreessen Horowitz did not respond to TechCrunch's or Bloomberg's requests for comment. Databricks and the DOJ declined to comment. No enforcement action has been filed, and an investigation is not a finding.
