- Axios and The Decoder, citing Bloomberg, reported that the DOJ is examining Andreessen Horowitz’s board roles at Databricks and Fivetran. [1][2] - Ben Horowitz is identified in public company and industry records as a Databricks director; a16z’s official biography identifies Martin Casado as a Fivetran director. [3][4] - Databricks and Fivetran overlap in parts of the data-infrastructure market but also maintain a formal partnership in which Fivetran moves data into Databricks. [5] - Section 8 of the Clayton Act turns on competition, statutory financial thresholds and limited exceptions; it does not require proof of actual competitive harm when the prohibition applies. [6][7]
The Justice Department is examining whether Andreessen Horowitz created an illegal board interlock by placing partners at two enterprise data companies that compete in parts of the same market, according to reporting by Axios and The Decoder, which cited Bloomberg. [1][2]
The reported inquiry centers on Ben Horowitz’s board seat at Databricks and Martin Casado’s seat at Fivetran. The DOJ has not publicly confirmed the matter; Axios reported that the department declined to confirm or deny the investigation. [2]
The board roles under scrutiny #
Andreessen Horowitz’s official biography for Martin Casado lists him as a current Fivetran director. It also lists his prior board service at dbt Labs, which Fivetran acquired. [3]
Public company and industry records identify Ben Horowitz as a Databricks director. The Information’s Databricks organizational chart lists Horowitz among the company’s outside directors, while Databricks’ own public materials identify him as a co-founder and general partner at Andreessen Horowitz. [4] Axios reported that the DOJ is examining whether partners at the venture firm can simultaneously sit on boards of rival companies. It also reported that Andreessen Horowitz did not respond to a request for comment. [2]
What Section 8 prohibits #
Section 8 of the Clayton Act, codified at 15 U.S.C. §19, generally prohibits a person from simultaneously serving as an officer or director of two corporations that are engaged in commerce and are competitors, if eliminating competition between them by agreement would violate the antitrust laws. The statute includes a financial threshold and de minimis exceptions tied to competitive sales. [6]
The Federal Trade Commission describes Section 8 as a structural prohibition. When the statutory conditions are met and no exception applies, the government does not need to prove that the interlock caused higher prices or another measurable competitive injury. The FTC announced 2026 thresholds of $54.402 million for the larger-company test and $5.4402 million for one of the exceptions. [7]
The DOJ has previously argued that an investment firm can face Section 8 exposure when its employees or other representatives act as its deputized directors at competing companies. In prior matters, the department reported that directors resigned or companies declined to exercise board-appointment rights without admitting liability. [8]
Competitors, partners or both #
Databricks and Fivetran do not sell identical products. Databricks markets a broader data and AI platform, while Fivetran specializes in automated data movement and connectors that transfer information from applications and databases into destinations such as Databricks. [5]
The companies’ commercial relationship is documented. Fivetran and Databricks announced a partnership in February 2020, and Databricks continues to offer Fivetran through its Partner Connect system. Fivetran markets the integration as a way to move data into Databricks for analytics and machine-learning workloads. [5]
That partnership does not, by itself, resolve the Section 8 question. The statute asks whether the corporations are competitors in a relevant line of commerce and whether the financial thresholds and exceptions apply. The reported inquiry could therefore concern narrower overlaps in data ingestion, transformation or analytics rather than treating the companies as interchangeable across their entire businesses. That is an inference from their public product descriptions, not a stated DOJ conclusion. [5][6]
No public finding of wrongdoing #
The reported inquiry is not a public charge or finding that Andreessen Horowitz, Databricks or Fivetran violated antitrust law. Axios reported that the DOJ declined to confirm or deny the investigation and published only a general statement about prioritizing affordability and competition. [2]
A review of the DOJ Antitrust Division’s public case filings, closing statements and public-documents pages did not identify a complaint, settlement or other public filing naming Andreessen Horowitz, Databricks or Fivetran in this matter as of August 18, 2026. The absence of a public filing does not establish that the department has not issued a confidential civil investigative demand. [9]
If the department concludes that the relevant overlaps and statutory thresholds are satisfied, the public Section 8 matters reviewed by DOJ suggest that a likely remedy would involve a director or designee leaving one board. Whether that occurs here will depend on facts that have not been publicly disclosed, including the firms’ competitive overlap, the legal status of the a16z representatives and any statutory exception.
