Edinburgh-based legal technology startup Wordsmith AI has raised $25 million in Series A funding led by Index Ventures, pushing its valuation above $100 million and establishing it as one of Scotland's fastest-growing tech companies.

The company is revolutionizing how legal departments operate by deploying AI agent fleets to support legal teams across organizations. Wordsmith ambitiously describes its goal as enabling "legal engineering" – embedding legal intelligence directly into business workflows through intelligent agents that review contracts, answer queries, and streamline decision-making processes.

In parallel with developing its platform, the company has made a significant investment to train and upskill legal professionals, so they can take advantage of the full potential of the Wordsmith platform. Following this approach, says the startup, "[l]egal stops firefighting—and starts engineering."

"Gone are the days of legal being seen as a blocker; it is now a revenue accelerator," said CEO Ross McNairn, who founded the company after transitioning from lawyer to engineer. The platform integrates seamlessly into existing tools like Slack, email, and Google Docs, allowing legal teams to scale their expertise without expanding headcount.

Major clients including Deliveroo, Trustpilot, Remote.com, and Multiverse are already using the platform to reduce deal cycles and eliminate bottlenecks. The company is pioneering a new role – the "legal engineer" – that combines legal expertise with technical skills to manage AI agent deployments.

With this funding, Wordsmith plans to expand operations to London and New York while deepening its AI infrastructure capabilities.
