Solo60 Raises $3.3M for Private, App-Bookable Micro-Gyms

The London-based fitness startup lets consumers, personal trainers and influencers find private training spaces in micro-gyms located throughout London’s capital city

As fitness floors become increasingly crowded, one London-based startup is among the companies exploring viable alternatives.

Founded by Ben Alderton, Solo60 has built a rapidly expanding network of private, technology-enabled micro-gyms that can be booked by the hour through a mobile app.

Now, the company has secured £2.5 million ($3.3 million) in new funding to accelerate its expansion across the United Kingdom while laying the groundwork for international growth.

Launched in 2019, Solo60 is built around a simple premise: giving consumers access to a fully equipped gym space without traditional memberships or the unpredictability of shared facilities. Through its platform, users can reserve an entire training studio for personal workouts, client sessions or small group training. Bookings are also available on ClassPass.

For Alderton, the concept was shaped by his own experience working as a personal trainer. Frustrated by the high rents and restrictive contracts required to train clients inside large gym chains, he began exploring ways to create a more flexible training environment. With many fitness professionals leaving the field within their first few years due to unsustainable costs and working conditions, Alderton saw the concept as a solution for these pain points.

“As a personal trainer, I was doing well, but the system around it never felt right,” Alderton said. “Trainers were paying high rents to big gyms, locked into one location, and often restricted in how they could run their own business or look after their clients. At the same time, members were tied into long contracts only to walk into overcrowded spaces where it was difficult to train properly. In 2019, I started thinking about a different model – something simpler and fairer. What started as an escape plan from that traditional system quickly became a much bigger vision: building a network of private wellness spaces connected through technology and accessible on demand.”

Solo60 converts underused city spaces into compact, design-forward micro-gyms. Since launch, the company has grown steadily across London with over 20 sites currently bookable. Its network is used by personal trainers, everyday consumers, physiotherapists and even content creators looking for private filming locations.

Two additional locations are scheduled to open in central London at St. Katharine Docks and South Bank Central, and Solo60 is also preparing to launch its first site outside the U.K.’s capital, in Newbury.

The newly secured funding will support this next stage of growth, helping the company scale toward its long-term goal of operating roughly 80 sites across London. The investment will also help establish the foundation for international expansion into markets including Ireland, the Germany-Australia-Switzerland (DACH) region, Stockholm, Sweden, and the United States.
