Former DOJ antitrust chiefs launch FluxCap to bring AI to plaintiffs

Jonathan Kanter and Doha Mekki, former heads of the US Justice Department’s antitrust division, launched FluxCap on October 28, 2026, a legal AI startup for plaintiffs’ lawyers and government enforcers, with $6.4 million in seed funding from investors including Y Combinator, Bloomberg Beta and Burford Capital. The company aims to help smaller legal teams pursue complex cases against better-funded opponents. FluxCap’s three connected engines are Almanac, which organizes legal precedents; FluxFacts, which links claims to evidence; and Vision Manager, which helps lawyers refine strategy. Former Palantir lead engineer Marshall Seid is chief technology officer, and the startup is beginning with antitrust while planning other specialties.
