BriefCatch Secures $6M Series A to Scale Secure, AI-Assisted Legal Writing

BriefCatch has closed a $6 million Series A led by Full In to speed up product development and expand its footprint across the legal profession. The focus: expert-guided editing, practical AI assistance, and strict data safeguards that fit how lawyers actually draft.

As firms adopt generative AI and digitize core workflows, the stakes around accuracy, accountability, and security keep rising. This raise backs a platform built for legal writers who need clear guidance, tight controls, and tools that make arguments sharper without giving up ownership of the work product.

Why this matters for legal writers

Founded by legal-writing specialist Ross Guberman, BriefCatch integrates directly into Microsoft Word and delivers feedback grounded in proven writing principles. The platform offers optional, security-conscious AI features to tighten prose, sharpen reasoning, and keep lawyers in full control.

Lead investor Elodie Dupuy puts it plainly: firms feel the pull of AI, but also the risk. BriefCatch aims to accelerate associate development and serve as a check and balance on AI-generated text that's entering the drafting flow whether firms like it or not.

Dupuy also points to domain depth: focused expertise beats generic tools. That focus translates to customer value-and retention.

Traction and trust

BriefCatch reports a 99% customer retention rate, 100% gross retention among law firms and courts, and 126% net revenue retention-signals that usage is expanding and the product is sticking. For teams raising quality while keeping to style, precedent, and professional standards, those numbers matter.

Dupuy notes the company's momentum so far came with modest means. The new capital and operator network are set to unlock latent demand.

What the funding will fuel

  • Faster product development, including advanced AI-assisted writing tuned to legal workflows
  • Team growth and broader market presence across firms and legal organizations
  • Deeper investment in security, accuracy, and user control so lawyers retain oversight of final work

"We're excited to pair first-rate legal writing with a custom AI system that delivers real, career-advancing wins," said founder Ross Guberman, thanking customers across top firms and courts for their loyalty.

Practical next steps for firms and litigators

  • Set clear guidance for when and how AI can assist drafting, with partner review as the final gate.
  • Evaluate vendors on data handling, on-prem or private-cloud options, and audit trails.
  • Use tools like BriefCatch for objective, repeatable editing feedback that levels up associate work and reduces partner rewrites.
  • Track outcomes: turnaround time, edits per page, motion success rates, and client feedback on clarity.
  • Offer targeted AI and writing training so teams get faster without sacrificing judgment. For role-based upskilling, see AI courses by job role.
