Our take

Generally speaking, the healthcare sector is slow to adopt new technologies. HeliosX bucks the trend, having been founded in 2013 to provide quicker, convenient access to medications through the use of cutting-edge tech.

HeliosX aims to improve the quality, accessibility and affordability of healthcare across the UK, US and Europe. With millions of customers worldwide, it operates across the medical, dermatology, and nutritional supplement sectors through its top-selling brands and products - Dermatica (personalised skincare brand), MedExpress (telepharmacy), Levity (prescription weight loss), ZipHealth (online medical consultations & pharmacy) and their men's health brand, RocketRx.

HeliosX has seen its global revenue rocket from £60m to £180m between 2023 and 2024. This growth is impressive for a company that's had no external funding, and it aims to accelerate its expansion in 2025 by moving into new territories.
