‘AI for litigators’ startup Callidus raises $10m with participation from Foley & Lardner

Callidus Legal AI, an US AI platform that automates and accelerates core litigation workflows, today (15 July) announced $10m in funding, bringing the company’s total funding to date to $13M. The round was led by Cervin Ventures, with participation from AI Fund, Myriad Venture Partners, Tandem Ventures, Active Capital, Capital Factory and notably Am Law 100 law firm Foley & Lardner, plus a consortium of partners from an undisclosed top 25 law firm. Foley, which is a leading tech law firm, operates a fund called Foley Ventures, which is structured to invest in clients.

Callidus was founded in 2023 and, after gathering 10 million US cases from sources including CourtListener and OpenLaws and building a database, launched specialised agents to enrich the database with detailed metadata. The company says it plans to roll out transformative new platform features throughout the second half of 2025.

“AI has advanced to the point where substantially automating legal work is no longer a question of possibility; it’s a series of tough but solvable engineering challenges. We’re building the most advanced and interactive AI platform for litigators,” said Justin McCallon, CEO and co-founder of Callidus Legal AI. “Success requires the right combination of a world-class user experience, a robustly engineered middle-layer, and high-quality legal data. Callidus brings all of that together cohesively. With the support of our partners, and on the shoulders of the research labs, we’re reinventing litigation legal tech.”

Callidus expects to triple its team size over the coming months, with new hires across product, engineering, customer success, and legal AI research in both Texas and California.
