Wordsmith AI has announced a $14 million extension to their Series B, led by new investment from Intact Private Capital alongside existing investors Highland Europe and Index Ventures. FT Ventures has also become a shareholder in Wordsmith.

The additional investment follows a period of rapid growth for Wordsmith, with the company stating that revenue has grown 14x year over year and the platform is now used by more than 500 companies, including BT, FT, Sage, Starling, Canva, and Safelite. The funding deepens Wordsmith’s presence in North America, where demand from enterprise legal teams is accelerating, and strengthens its footprint in the financial services and insurance sectors.

Unlike legal AI startups serving both law firms and corporate legal departments, Wordsmith is built exclusively for in-house legal teams. Wordsmith believes the two markets require fundamentally different products: while law firms manage external matters and operate around billable hours, in-house teams need to resolve more work internally, control outside counsel spend, and provide faster support to every part of the business.

“Intact Private Capital is excited to support Wordsmith at this stage of growth,” said Justin Smith-Lorenzetti, Managing Director at Intact Private Capital.

“In-house legal teams at financial services and insurance companies need legal infrastructure that can operate at enterprise scale while maintaining the control and auditability required in highly regulated environments. Wordsmith is built precisely for that challenge, with a deep understanding of how these organizations work and the infrastructure to match.”

Enterprises serving more than 10,000 employees are running on Wordsmith today. Customers are seeing seven-figure savings in outside counsel spend in the first weeks of use. Teams that previously spent 70 to 80% of their week on routine work are reclaiming that time for higher-value matters. Regulatory and multi-jurisdiction questions that once went straight to external counsel are now handled in-house first, with outside support reserved for where it genuinely adds value.

“Wordsmith’s solutions for in-house legal teams are rethinking not only how lawyers work, but also how commercial and legal teams engage with each other,” said Alexandra Calinikos, Chief Investment Officer at FT Ventures.

“FT’s own in-house legal team has chosen Wordsmith as its enterprise legal AI platform, providing the FT’s business faster access to legal support. Alongside this operational relationship, FT Ventures is excited to support Wordsmith in their next phase of growth as they deliver the infrastructure to make legal work more efficient for businesses globally.”

“Every dollar that leaves a legal team and goes to outside counsel is a decision,” said Ross McNairn, CEO and co-founder of Wordsmith.

“Too often, those decisions are made by default rather than by design, because legal teams have never had the infrastructure to handle the work internally. Wordsmith gives them that infrastructure. Requests come in, AI agents complete the routine work, lawyers approve what requires judgment, and every step is recorded. The result is a legal function that keeps more work in-house, spends less on external counsel, and can finally show the business the impact it delivers.”
