Rami Karabibar and Ray Mieszaniec were rejected from Y Combinator at least three times. And that was just the beginning.“We lost track, but we had hundreds of meetings with VCs,” said Karabibar, who in 2019 cofounded legal AI startup EvenUp with Mieszaniec and Saam Mashhad. “They kept saying to us: ‘What are you doing? Legal tech sucks, AI sucks, personal injury sucks. Those are three negatives.’”Mieszaniec adds, “Some investors said: ‘Your founding team is great, but this is the dumbest idea.’”Karabibar, Mieszaniec, and I are talking five years later—and the conversation has radically changed. Legal AI companies are some of the hottest in the market, and EvenUp, focused on the $61 billion personal injury space, has gone from chasing to being chased: The company has now secured its fourth funding round in about two years. EvenUp has raised a $150 million Series E, led by Bessemer Venture Partners, Fortune has learned. This brings the company’s valuation to north of $2 billion. B Capital, SignalFire, Lightspeed, HarbourVest, Adams Street, and Broadlight Capital all invested in the round, as did the venture arm of Lexis Nexis owner RELX. EvenUp’s total capital raised is now at $385 million, and the company is solving personal injury’s relentless paperwork problem.“The average case takes about two years,” said Karabibar. “We see cases dragged on far longer than they need to, and they settle for less than they should. Attorneys are grinding, doing about 100 cases a year. So, it’s hard for them to stay on top of everything.”EvenUp is growing in a moment where the economics of AI startups are in flux—you have to triage rising compute costs with customer pricing. It’s a delicate dance: If a customer loves the product, they’ll use it a lot, and you’d better have the compute to back that up (and be pricing accordingly so you don’t drown). Success, they say, depends on delivering quantifiable value; otherwise, a law firm customer just churns. (One example: Karabibar and Mieszaniec say that EvenUp’s largest customer pays over $4 million annually, is clocking around $40,000 revenue per employee.)Right now, Mieszaniec says, as big of a legal practice as personal injury is, there are still cases that are getting left on the table. The idea: That AI will help create enough efficiency that it changes what’s possible in terms of caseload, and for personal injury victims. “Attorneys are probably turning down one or two cases,” Mieszaniec told Fortune. “Maybe half of these injury cases are actually represented by an attorney. For the other half where you don’t have support, these cases are settling a lot lower.”Industries are often, I think, forged in the image of their customers. And this will continue to be true at the intersection of personal injury law (which is experiencing its own floor-is-lava economics) and AI. Personal injury is famously competitive and visceral, most known to outsiders as “the law firms with the billboards and commercials.” EvenUp has, so far, helped resolve more than 200,000 personal injury cases and more than 2,000 U.S. firms are using the platform. Still, they have personal injury-focused competitors, from a16z-backed Eve to Supio. Companies like Harvey, valued $5 billion, loom large.“I don’t think there’s gonna be 100 players in this space,” said Karabibar. “I think it’s going to be a winner-take-most dynamic, and ultimately it’s our game to lose.”Mieszaniec is even more direct: “It’s not winner-take-all. It’s the last man standing. And I don’t care. We’re ready to stand here for as long as we have to.”See you tomorrow,Allie GarfinkleX: @agarfinksEmail: alexandra.garfinkle@fortune.comSubmit a deal for the Term Sheet newsletter here.Joey Abrams curated the deals section of today’s newsletter.
