About Fletchers Solicitors & the AI / Data Science Team

Fletchers is afar growing consumer law firm specialising in personal injury and clinical negligence, and 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.
