Andreessen Horowitz is facing scrutiny from the US Justice Department over board roles held by its partners at competing data companies. The investigation, reported by Bloomberg, centers on whether those seats create a possible antitrust violation in a fast-growing corner of the AI economy.
What the DOJ is examining
The core issue is simple: Andreessen Horowitz backs both Databricks and Fivetran, and partners from the venture capital firm sit on both companies' boards. Cofounder Ben Horowitz sits on the Databricks board, while partner Martin Casado sits on the Fivetran board.
According to Bloomberg, both companies help businesses collect, organize, and analyze large amounts of data. That overlap matters because it puts them in competition with each other. The DOJ is now looking at whether those board positions cross a legal line.
Andreessen Horowitz is not a small investor on the edge of the market. The firm has about $90 billion in assets under management and holds stakes in AI companies including OpenAI, SpaceX, and ElevenLabs. Databricks was most recently valued at $190 billion.
Why competing board seats matter
The concern comes from a 1914 law that bans so-called interlocking directorates. In plain terms, the same person is not supposed to sit on the boards of two directly competing companies, because that arrangement could allow sensitive information to move between rivals and weaken competition.
In this case, the DOJ is not only looking at one person holding two seats. The more notable question is whether a venture firm can have multiple partners serving on boards across companies that compete with each other.
That distinction is important. Venture capital firms often invest across related markets, and board seats can give investors influence, information, and a role in company strategy. When portfolio companies compete, those advantages can become legally sensitive.
How Databricks, Fivetran, and dbt Labs fit in
Databricks and Fivetran are the central companies in the reported investigation. Both are backed by Andreessen Horowitz, and both operate in data infrastructure for businesses.
Casado also sat on the board of dbt Labs, which Fivetran acquired in June. The DOJ reviewed that merger for months before clearing it without conditions.
Bloomberg reports that the nearly year-old probe began around the same time and remains ongoing. That means the merger review ended, but the broader question about board seats and competition has not been resolved.
What usually happens in cases like this
These matters often end with directors leaving one of the boards. Under the Biden administration, the DOJ forced executives to resign in about a dozen cases.
The Andreessen Horowitz matter stands out because the reported probe focuses on the firm itself. Bloomberg says the DOJ is examining the company because several of its directors sit on competing boards.
That makes the case more than a narrow question about one board member. It raises a broader issue for large venture firms with many investments across overlapping areas of artificial intelligence, data infrastructure, and enterprise software.
The political backdrop
The investigation also arrives against a political backdrop involving Andreessen Horowitz and the second Trump administration. According to Bloomberg, the firm has aligned itself closely with the White House and successfully pushed to roll back many AI safety rules that benefit its own portfolio.
Horowitz and cofounder Marc Andreessen donated millions to a pro-Trump group in 2024. Those ties add another layer of attention to an already high-profile antitrust probe.
For now, the reported DOJ investigation remains ongoing. The immediate question is whether the board roles at Databricks and Fivetran violate antitrust rules. The larger question is how regulators will treat the influence of major AI investors when their portfolio companies compete with one another.
