The US Justice Department is examining whether investment partners at Andreessen Horowitz are improperly sitting on the boards of competing artificial intelligence companies, according to people familiar with the inquiry. The companies said to be at issue include Databricks, where co-founder Ben Horowitz is a director, and Fivetran, where partner Martin Casado sits on the board. Both firms sell tools for collecting and analysing large amounts of data, and the probe has not resulted in any public action.
