Jonathan Kanter, who left the Justice Department’s Antitrust Division in 2024, and former acting chief Doha Mekki have started a new company called FluxCap. The startup offers an AI‑powered legal research platform that pulls facts, legal frameworks and potential weaknesses from large case files. It is aimed first at antitrust lawsuits but the team plans to add other practice areas. FluxCap’s first client is antitrust boutique firm Kressin Powers, and the company says the tool gives a small team the capacity of “20‑plus people” working around the clock.

## The facts

- FluxCap was founded by former DOJ antitrust chief Jonathan Kanter and former acting chief Doha Mekki.
- Kressin Powers is named as one of FluxCap’s first customers.

## Why it matters

Small antitrust teams can use FluxCap’s AI to analyze massive evidence piles, letting them challenge large tech companies with far fewer resources.
