BriefCatch, a legal technology company devoted to helping legal professionals improve their legal writing, has raised a $6 million Series A led by the growth equity investing firm Full In.

BriefCatch says the round comes amid its highest revenue growth rate to date, with 126% net enterprise revenue retention among large law-firm customers. The start-up’s customers include more than 50 of the AmLaw 200 and many of the nation’s state and federal courts.

The funding will support both AI product expansion and a targeted acquisition strategy, as BriefCatch builds toward a unified, Word-native AI platform for elite legal writing, editing, and research, according to founder and CEO Ross Guberman.

Guberman says that more than three dozen funds approached the company to lead its Series A. He selected Full In based on its instant understanding of BriefCatch’s technical roadmap and the experience of its founding partner Elodie Dupuy in scaling and exiting like-minded start-ups.

“This investment lets us accelerate two things at once: disciplined acquisitions and deeper product development,” Guberman said. “Our goal is to give lawyers and judges a single, integrated AI platform for elite legal writing and editing, and we’re already building capabilities that leap past what existing editing tools — or generic genAI — can do today.”

Earlier this year, BriefCatch introduced version 4 of its software, which included two new features that use gen AI to enhance legal document preparation: AI-driven Bluebook citation correction and a context-aware writing advisor.
