3 Exciting Entrepreneurs: The UK's Fastest-Growing Tech Founders of 2026
10 November 2026 · 3 min read
Every November, the Deloitte UK Technology Fast 50 ranks the country's fastest-growing technology companies by revenue growth over three years. The 2026 results were announced at a ceremony on 5 November, and the top of the table makes for striking reading. This week we are looking at three of the founders behind it: one making home workouts smarter, one sending robots through warehouses, and one changing how people rent cars around the world.
What links them is not just eye-catching growth figures. Each has taken a practical, everyday problem and built a product that solves it at scale, from London, Oxfordshire and Cardiff. Between them they cover fitness, logistics and travel, three very different markets, which says a lot about how widely technology is now reshaping ordinary parts of life.
A quick word on the numbers. Growth percentages like these are measured over three years, so they reflect how far a company has come from where it started, not just how big it is today. Young businesses with small early revenues can post enormous percentages. That does not take away from the achievement: it shows customers are signing up quickly, and that the founders have built something people want to pay for.
Varun Bhanot, Magic AI
Varun Bhanot is the co-founder and chief executive of Magic AI, a London company that makes an AI-powered smart fitness mirror. The mirror is designed for home workouts and virtual personal training, giving people guidance and feedback without needing to go to a gym.
Magic AI was founded in 2022, and it has grown fast. It took the No. 1 spot in the 2026 Deloitte UK Technology Fast 50, with revenue growth of 19,774% over three years. The company says it has helped more than 30,000 people in 43 countries, and it recently raised Series B funding to support its expansion into the United States.
For a business only a few years old, topping a national ranking like this is a clear sign that people are ready to bring more personalised fitness into their homes. It also shows how AI can be built into a physical product that sits in someone's living room, rather than living only on a screen or in an app.

Andrei Danescu, Dexory
Andrei Danescu is the co-founder and chief executive of Dexory, based in Wallingford, Oxfordshire. Dexory builds AI-powered autonomous robots that move through warehouses scanning shelves and stock, and uses that data to create digital twins, live digital copies of a warehouse that give operators real-time visibility of what is where.
The company came second in the 2026 Deloitte UK Technology Fast 50, with three-year revenue growth of 17,687%. It also topped the list's Women in Leadership category. Dexory started life under a different name, BotsAndUs, before becoming the business it is today, a reminder that the first version of a company is rarely the final one. For anyone running a warehouse, knowing exactly what stock is on which shelf, at any moment, is the kind of quiet operational win that saves time and money every day.

Ammar Akhtar, Final Rentals
Ammar Akhtar is the founder and chief executive of Final Rentals (also written Finalrentals), which is headquartered in Cardiff. The company runs BLADE, an AI-powered platform that helps people find and book car rentals around the world.
Final Rentals ranked 14th in the 2026 Deloitte UK Technology Fast 50, with 2,865% revenue growth over three years. In February 2026 the business expanded into Pakistan, where Akhtar was born, launching airport rentals in Karachi, Lahore and Islamabad. That added to a network that already reached more than 60 countries.
It is a good example of a Welsh business thinking globally from day one, and of a founder bringing his company back to where his own story began. Car hire is a crowded and competitive market, so standing out in it, and growing this quickly, is no small thing.

What founders can take from this
Solve a problem people meet every day. Exercise at home, finding stock in a warehouse and hiring a car are ordinary tasks. Making them simpler is where the growth came from.
Your first name is not your final form. Dexory began as BotsAndUs. Be willing to refocus as you learn what customers value most.
You can build global from anywhere. Wallingford and Cardiff are proof that a fast-growing tech company does not have to be in central London.
