Former DOJ antitrust chief launches AI startup for monopoly cases
🎧 Listen to this story
Jonathan Kanter, the former head of the US Justice Department’s Antitrust Division, and Doha Mekki, the division’s former acting chief, launched FluxCap. The startup sells a platform built with proprietary technology and large language models for legal research and analysis, initially focused on antitrust cases and planned to expand into other practice areas. Kanter says the tool can identify weaknesses in legal arguments, sift through large volumes of documents and find signals of potentially anticompetitive conduct.
The team includes former Justice Department staffers and former Palantir engineers. Antitrust boutique Kressin Powers is among FluxCap’s first customers, and Kanter says the company is in talks with public and private enforcers. He says the platform can give a small team the capacity of “20-plus people” working around the clock, acting as a force multiplier for investigators and lawyers.
Why it matters · editorial interpretation
FluxCap puts large language models into a high-impact legal role: supporting research, analyzing documents and assessing arguments in antitrust cases. Because the described capacity comes from Kanter, the tool’s practical reach still depends on how legal teams and authorities validate it in real-world work.
