Clearbrief, a legal technology company that uses AI to help lawyers find and insert facts to support their legal writing, has raised an additional funding round of approximately $4 million. This brings the company’s total funding since its founding in 2021 to nearly $8 million.

This latest round was led by Authentic Ventures, How Women Invest, and existing investor Reign Ventures, which are all funds with track records of investing in women-led and diverse teams.

Also participating in the round were an investment fund affiliated with law firm Wilson Sonsini and existing angel investors.

Clearbrief CEO Jacqueline Schafer, who founded Clearbrief based on her own experiences as a litigator and appellate lawyer, said that this latest round was driven by the product’s rapid growth among AmLaw 200 law firms.

“It was an opportune time to take in some additional capital to fuel the expansion of our team,” she said. “We liked the opportunity to partner with investors who believe in responsible AI built by diverse teams, with a focus on building a sustainable, profitable business that’s here for the long haul.”

Clearbrief is a Microsoft Word Add-In that helps attorneys find, insert, and check facts when drafting briefs and in other legal writing. It can also be used to check factual and legal references in an opponent’s brief.

“Our vision is that litigators and in-house teams will draft and analyze every single Word document with Clearbrief,” Schafer said. “In an AI-powered world, colleagues and courts demand a secure, seamless experience that lets them view the factual and legal evidence behind legal prose while reading and writing.”

“We chose to invest in Clearbrief because we heard so emphatically from customers that Clearbrief’s AI tools are making an impact on the day-to-day work of the most sophisticated law firms, distinct from other AI platforms that haven’t yet established their concrete value to litigators,” Julie Castro Abrams, managing partner of How Women Invest, said in a statement.
