About Fletchers Solicitors & the AI Team

Fletchers is a rapidly growing consumer law firm specialising in personal injury and clinical negligence, with a growing practice in family and private client. Fletchers was one of the first consumer law firms to deploy a machine learning tool for legal work (a decision support system for screening incoming cases, launched in 2017) and was one of, or the first, law firm to have a dedicated AI department, which started in August 2023. Since then, we have been experimenting with a broader range of ML techniques, extending those tools already in use, and productionising new ones through our growing data science & engineering teams. We believe that we are well positioned to leverage Fletchers' unique legal‑medical dataset and industry expertise to build AI tools that will shape the future of consumer law.

We are well funded through our Private Equity backers, which allows us to invest heavily in the development of sector‑specific AI tools that assist, automate, and augment our specialist legal work. Tools we have built range from simple behind‑the‑scenes custom model inference, to agentic‑AI pipelines for 'always on' monitoring, to the core user interface that some of our colleagues work on for 90%+ of their day. We're also commercialising these tools so that other specialist law firms can leverage Fletchers' legal and AI expertise, and have an ambitious agenda for external growth for the next 18 months.

Fletchers is headquartered in the North‑West of the UK, with offices in Manchester, Liverpool, Leeds, Southport, Bolton, Cambridge, Reading, Birmingham, Northampton, and Newcastle. Many colleagues work primarily from home. The existing AI team is distributed across London, Manchester, Liverpool, Cambridge, and Bristol, and we typically meet in person once or twice per month in Manchester.
