Two former senior US Justice Department antitrust officials have launched an artificial intelligence startup designed to help lawyers manage complex litigation, moving from government enforcement into a fast-growing market for legal technology.
Jonathan Kanter, who led the Justice Department’s antitrust division under President Joe Biden, and Doha Mekki, a former acting head of the division, have founded FluxCap, an AI-powered platform intended to help legal teams analyze evidence, evaluate claims and develop litigation strategies.
The launch was reported Wednesday by The New York Times in its DealBook coverage. The company separately announced that it had secured $6.4 million in seed financing from investors including Y Combinator, Bloomberg Beta, Burford Capital, Omidyar Network, Deep Work Capital and Coalition Operators.
The venture represents a new chapter for two lawyers who helped shape the Biden administration’s aggressive approach to corporate competition, particularly in the technology industry.
Rather than pursuing antitrust cases on behalf of the federal government, Kanter and Mekki are now seeking to equip lawyers with technology that could reduce the financial and operational barriers to bringing major lawsuits.
AI Takes Aim at the Cost of Litigation
FluxCap is entering a legal technology industry attracting substantial investor interest as artificial intelligence promises to change how attorneys research cases, review documents and prepare arguments.
According to the company’s announcement, FluxCap spent more than a year in development before its public debut. Its initial focus is antitrust litigation, a field that frequently involves extensive document discovery, complicated economic evidence and lengthy court proceedings.
The platform combines three systems designed to organize legal precedent, connect factual assertions with supporting evidence and assist lawyers in developing case strategies.
The company says the technology can help attorneys prepare complaints, analyze discovery materials and identify weaknesses in opposing arguments while preserving human oversight of legal decisions.
Its central commercial proposition is that smaller teams could handle litigation workloads traditionally requiring much larger groups of attorneys.

Mekki said in the company’s announcement that the time and expense associated with major litigation can prevent potentially valid claims from reaching court. FluxCap aims to address those constraints by providing lawyers with more sophisticated analytical capabilities.
Former Regulators Enter a Competitive Market
The startup’s arrival comes amid growing investment in AI-powered legal services, where established firms and newer technology companies are competing to automate parts of the legal workflow.
According to industry figures cited by We Are the Frontier, legal technology startups attracted approximately $3.2 billion in financing in 2025, nearly 150% more than in 2024.
FluxCap is seeking to differentiate itself by focusing on specialized legal reasoning rather than general-purpose document automation.

The company says its technology was developed jointly by experienced antitrust lawyers and engineers, including former employees of Palantir Technologies.
Marshall Seid, previously a technology lead at Palantir and chief technology officer of Quiller, serves as FluxCap’s chief technology officer.
The startup’s founding group also includes former Justice Department and White House officials, bringing together legal expertise and software engineering experience.
According to FluxCap, its platform is designed to allow attorneys to review and verify factual assertions, legal citations and analytical conclusions generated through the system. That approach addresses a persistent concern surrounding generative AI in legal practice: the possibility of inaccurate or fabricated information appearing in legal work.
A New Role for Washington’s Antitrust Veterans
Kanter and Mekki’s move into the private technology sector is notable given their previous roles in federal competition enforcement.
During the Biden administration, the Justice Department’s antitrust division pursued major cases involving dominant technology companies, reflecting a broader effort to strengthen enforcement against alleged anticompetitive business practices.
Their new venture approaches the challenges of corporate power from a different direction, seeking to make sophisticated litigation tools available to legal teams with fewer resources.
FluxCap says its technology is intended to supplement lawyers’ professional judgment rather than replace attorneys.
The company is making the platform available to law firms, corporate legal departments and government enforcement agencies through research licenses, litigation support and enterprise offerings.
Although antitrust is its initial specialty, FluxCap says additional areas of legal practice are under development.
The startup’s ability to compete will depend partly on whether its specialized approach can deliver reliable results in cases where mistakes can have significant financial and legal consequences.
