Our take

HeliosX is a global digital healthcare group behind some of the most recognised online health brands, including MedExpress, Dermatica, ZipHealth, RocketRX, and Levity. The company has earned the trust of millions of patients by combining technology with deep clinical expertise, supported by its own pharmacies, manufacturing capabilities, and in-house medical, research, and pharmacy teams.

By 2025, HeliosX had treated over 1.2M patients worldwide and established £781M in revenue, marking more than 300% year-on-year growth and established itself as a clear market leader in the UK. Its impact goes beyond commercial success too, with weight-loss treatments alone helping patients lose millions of kilograms of excess weight, contributing to meaningful improvements in long-term health outcomes. At the same time, the business expanded internationally, successfully launching in Germany and Canada while continuing to grow its presence in the US.

Now its looking towards 2026, and hopes to reach £1.6B in revenue, expand into eight global markets, and significantly widen its range of conditions and treatments, with a focus on shaping the future of digital healthcare. Its goal is to become a truly world-leading healthcare partner and one that combines scale, speed, and clinical rigour to redefine how personalised care is deliver, and to create systems and products that improve lives at a global level for years to come.
