Ex-DOJ antitrust chiefs launch AI legal startup

· Fact-checked before it aired. Unconfirmed claims from this segment are not shown.

On October 28, 2026, former DOJ antitrust chiefs Jonathan Kanter and Doha Mekki launched FluxCap, an AI litigation platform focused initially on antitrust. The company raised $6.4 million in seed funding from Y Combinator, Bloomberg Beta, Burford Capital, Omidyar Network, Deep Work Capital, and Coalition Operators. Its CTO is Marshall Seid, a former Palantir tech lead. The product includes modules called Almanac, FluxFacts, and Vision Manager.

Kanter says the DOJ was only able to pursue about 10% of the cases it believed were worth bringing because of resource constraints. FluxCap is designed to help smaller legal teams litigate complex cases against well-resourced opponents. Mekki frames the mission as expanding economic justice and legal representation.

What the hosts said

MTwo people who ran federal antitrust just raised six point four million dollars... to sell AI tools to plaintiffs.
CSo the referees quit the league, then opened a store selling fouls.
MThat's the cynical read. The Index Brief on X flagged the launch: Jonathan Kanter and Doha Mekki started FluxCap.
CKanter and Mekki. These are the people who took on Google and Apple for the DOJ.
MLaw360 confirms it. The seed round includes Y Combinator, Bloomberg Beta, Burford, and Omidyar.
CBurford. That's litigation finance, not a charity.
MRight. The product is aimed at smaller legal teams fighting complex antitrust cases.
CDo I automatically trust ex-enforcers selling litigation tech? No.
MWhy not? They built major cases against some of the biggest companies.
CBecause they now know exactly how to package that inside knowledge.
MKanter says the DOJ only had resources for about ten percent of the cases it thought were worth bringing.
CTen percent! That's an admission the system was starved. So they left and built a subscription.
MThat's exactly my point. If Congress won't fund it, private plaintiffs need tools.
CNo, no, wait— that's the revolving door with a Y Combinator batch number.
MIt's the opposite of the usual sellout. They didn't go work for Google or Apple.
CThey're monetizing inside knowledge. Same behavior, better branding.
MThe product includes modules called Almanac, FluxFacts, and Vision Manager. Very legal tech.
CDon't pivot to product names. The conflict matters.
MI'm not pivoting. Mekki says, and I quote, 'More people can have representation and have better access to economic justice.' That's a real mission.
CFine. But they took money from Burford. People who profit from lawsuits now back the people bringing them.
MLitigation finance already exists. This is software, not a case fund.
CThe software tells plaintiffs which cases to bring, and Burford is standing by with cash.
MMaybe. I'd rather have more cases brought than the ten percent Kanter described.
CCareful, you're starting to sound like a class-action ad.
MHa. I'll own that. Ask yourself: if this helps a small firm match a team of Big Tech lawyers, isn't that good?
CIt could be. I just want a cooling-off period before top regulators sell into the same market.
MThat's fair. At minimum, Kanter and Mekki know where the enforcement gaps are.
CThey do. And Kanter says 'We're not trying to be a better lawyer; we're trying to help lawyers be better.' That I believe.
MSo we agree more than we think.
CDon't tell anyone. But I still wouldn't call FluxCap a public service. It's a startup.
MA startup with six point four million in seed and a very specific customer list.
CAnd a former Palantir tech lead as CTO. This isn't two lawyers with a PowerPoint.
MThat tells me they'll actually build the AI, not just sell access.
CWhich makes the conflict question more urgent, not less.
MFair enough. But the bigger scandal is that DOJ could only chase one in ten cases.
CIf this moves it to one in eight, I'll call it a win. But I'll watch who funds them next.
MSame. Legal Tech Circle says this six point four was the only legal tech equity round on its tracker that week.
CSo little money, such big antitrust energy. That's the story.
MAnd the first customer might be someone who never got their day in court.
CThat's the pitch. Turns out justice has a software layer now.
MWe'll see if it works. I'm not ready to call it a public good.
CNeither am I. But I'm watching.
