Most legal AI startups are being built for law firms. That is where the money is, and where the billable hour still reigns. Wordsmith is building for the other side of the table — the in-house teams whose job is to help companies move faster, not bill more hours.
The Edinburgh-based legal AI company today announced a $70M Series B led by Highland Europe and Index Ventures, bringing total funding to $100M. The round comes alongside new enterprise wins, including Sage and Starling, and accelerates a scaling push that will take the company toward 300 employees by the end of 2026. Wordsmith was founded in 2023 by Ross McNairn (CEO), Volodymyr Giginiak (CTO), and Robbie Falkenthal (COO), and is headquartered in Edinburgh with offices in New York and London. The company currently employs around 110 people.
McNairn is a lawyer-turned-technology executive who sold his first startup Dorsai Travel to Skyscanner, then spent five years as CPTO at TravelPerk — helping scale it to $170M ARR — and previously led Letgo’s product engineering organisation during its unicorn rise. Giginiak spent more than a decade at Facebook and Instagram.Falkenthal spent more than six years at KPMG Dublin before senior leadership roles at TravelPerk.
What it does
Wordsmith gives in-house legal teams a single platform to receive, route, resolve, and record every legal request that comes in from across the business — whether it arrives via email, Slack, Salesforce, or Teams. The platform reads the request, assigns ownership and priority, applies the legal team’s existing playbook to handle routine work automatically, and routes to a lawyer only when genuine judgment is required. Every action is logged as it happens: what was decided, by whom, and on what basis. The result is less reliance on outside counsel, faster business decisions, and a measurable record of legal’s impact.
“Legal does not need another filing cabinet, and it does not need another copilot that simply helps one lawyer work faster,” said McNairn. “Wordsmith is the front door that does the work. Requests come in, AI agents process the routine, lawyers approve what needs judgment, and every step is recorded as it happens.”
The round
Index Ventures, which led both the $5M seed round in June 2024 and the $25M Series A in June 2025, returns as a co-lead alongside new investor Highland Europe — whose portfolio includes Wolt, GetYourGuide, and N8n, which became a unicorn in 2025. The Series B brings Wordsmith’s total funding to $100M in just over two years from founding, one of the fastest funding trajectories in European legaltech.
Jean Tardy-Joubert, Partner at Highland Europe, said: “What is most exciting about Wordsmith is that this is a tool built for companies, rightfully involving all employees in legal affairs, in coordination with the in-house legal team. By taking a vertical approach, Ross and the Wordsmith team have established themselves at the forefront of the sector, with demonstrable market traction, impressive growth and more than 500 satisfied customers.”
Competition
Wordsmith operates in a legal AI market moving at extraordinary speed. As TFN has reported, Harvey raised $200M at an $11B valuation in March 2026 — but is built primarily for law firms and enterprise legal research, not the in-house workflow management layer Wordsmith occupies. Legora, the Swedish legal AI company, raised $600M at a $5.6B valuation and is expanding aggressively into European markets, making it Wordsmith’s most direct competitive threat on the continent. Both Harvey and Legora are focused on helping individual lawyers work faster; Wordsmith’s structural differentiation is that it is built around the flow of legal work across an entire organisation, not around a single lawyer’s desk. TFN has also covered Lexroom’s $50M Series B targeting continental Europe’s legal market — another signal of how rapidly the sector is fragmenting by geography and use case.
Market
The global legal AI software market stands at $5.21B in 2026 and is projected to reach $40.94B by 2034, growing at a CAGR of 29.4%, according to Fortune Business Insights. Within that, the corporate legal departments segment represents the largest current share — precisely the market Wordsmith is targeting.
The deeper question for Wordsmith — and for the in-house legal AI category more broadly — is whether the platform layer gets built by vertical specialists like Wordsmith, or whether Harvey and Legora, armed with combined capital of over $1.7B, simply expand downmarket and commoditise the workflow layer before Wordsmith can entrench it.
