The Justice Department has opened an investigation into Andreessen Horowitz, one of Silicon Valley’s most influential venture firms, focusing on its presence on the boards of two competing data companies, according to people familiar with the matter. The inquiry centers on whether the firm’s general partners, sitting simultaneously on the boards of Databricks and Fivetran, have used those positions to gather competitive intelligence.
The probe was first reported by TechCrunch and Axios, and it has left much of the venture industry puzzled. Venture firms routinely hold stakes in companies that compete with each other; portfolio overlap is so common that it has a name in the industry. The new theory the Justice Department appears to be testing is different: that a board seat is not just an investment position but a pipeline for competitive information, and that a firm holding seats at two rivals is in a position to move information between them.
Databricks and Fivetran are both data companies, but they operate at different layers of the stack. Databricks builds the platforms where companies store and analyze their data, and it has become one of the most valuable private software companies in the world. Fivetran automates the movement of data between systems, a critical piece of infrastructure for the same customers Databricks serves. Their customers overlap, their roadmaps converge, and the two companies are increasingly rivals for the same enterprise budgets.
The Justice Department’s interest reflects a broader shift in antitrust enforcement. Regulators have spent years focusing on mergers and acquisitions, blocking deals they say would harm competition. The a16z inquiry goes further, testing whether the structure of venture investing itself, with its overlapping boards and information flows, creates antitrust problems. If the theory prevails, it could change how venture firms staff their boards and how they disclose their portfolio relationships.
The venture industry’s response has been near-universal confusion. General partners said the investigation misunderstands how venture capital works: firms invest across categories, sit on boards to help companies grow, and routinely see information from many companies at once. The idea that a board seat is a channel for stealing trade secrets, they argue, inverts the fiduciary duties that govern the role. Board members are legally obligated to act in the interests of the companies they serve, not to harvest their secrets.
The legal questions are novel. Antitrust law has traditionally concerned itself with markets, prices and market power, not with information flows between investors and their portfolio companies. The a16z probe would require the Justice Department to show that the overlap in board seats gave the firm, or its portfolio companies, an unfair advantage that harmed competition. That is a theory with few precedents, and one that lawyers said would be difficult to prove.
The investigation also touches the delicate relationship between venture capital and the companies it funds. Startups accept venture money in part because their investors bring expertise, connections and board-level guidance. If board service becomes a legal liability, firms may become more cautious about which boards they take, and startups may find it harder to attract the kind of hands-on investors they have relied on.
The timing is awkward for a16z, which has been one of the most aggressive investors in the AI boom. The firm’s bets on data infrastructure and AI companies have made it a central player in the industry’s biggest deals, and a federal investigation into its governance practices adds a layer of risk to a portfolio built on relationships. The firm has said it cooperates with regulators and believes its practices comply with the law.
What happens next depends on where the inquiry leads. The Justice Department could close the matter after gathering information, or it could escalate, demanding documents, depositions and possibly changes to how the firm operates. The venture industry will be watching closely, because a precedent here would reshape the rules for every firm with overlapping board seats, and the uncertainty alone is already affecting how some funds think about accepting new directorships.
For the two companies at the center of the probe, the stakes are different. Neither Databricks nor Fivetran is accused of wrongdoing, and both have said they operate independently. But both are preparing for public markets, and a federal investigation touching their boards is not the footnote they would have chosen for their prospectuses. The probe may prove to be nothing, or it may prove to be the beginning of a new era in how Silicon Valley’s most important relationships are regulated. Either way, the question it raises has already been heard: whether the people who fund the next generation of technology companies are also, in the government’s view, the people who police their competition.
