Finmile has been named the fastest-growing business-to-business services firm in the UK and London in the 2026 UK Fast Growth Index.
The company also secured a place among the UK’s Top 200 fastest-growing independent businesses.
Finmile helps businesses manage and improve their operations through 2 products: Finmile OS, which brings operational planning and execution together, and Finmile Autonomy, which deploys AI workers across a company’s existing systems to complete operational jobs.
Those jobs include following up on vehicle inspections, recovering disrupted deliveries, resolving claims and reconciling billing. Teams can start with a single workflow and expand, with permissions and human approvals controlling the actions AI workers take.
Rich Pleeth, co-founder and CEO of Finmile, said: “We’re incredibly proud of the team behind this. Growing so much in 2 years takes a huge amount of hard work and customers who trust you to deliver.
“We built Finmile to solve the operational problems businesses deal with every day. Today, our AI workers are helping teams resolve those problems while they’re happening, freeing people to focus on running and growing their business. Being recognised as the fastest-growing B2B services firm in the UK is a brilliant milestone, and there’s plenty more we want to do.”
The 2026 UK Fast Growth Index identifies the 350 fastest-growing independent businesses across the UK’s nations and regions. Together, these businesses more than doubled their combined turnover in 2 years, rising from £4.3 billion in 2023 to £10.2 billion in 2025, an increase of 137%.
Professor Dylan Jones-Evans OBE, founder of the UK Fast Growth Index, said: “Finmile is a great example of the extraordinary talent and ambition we see in businesses across every part of the UK. Earning a place on this year’s Index, alongside firms that have together more than doubled in size in just two years, is a remarkable achievement, and the whole team should be very proud.”
