Ready to revolutionise healthcare, making it faster and more accessible than ever before?
How we started:
Back in 2013, our founder Dwayne D’Souza saw an opportunity to give people faster and more convenient access to medications using technology. We've grown rapidly since our inception, without any external funding whatsoever – achieving profitability through innovation and a highly disciplined approach to growth.
Where we are now:
We’ve earned the trust of millions of people worldwide through our top-selling products and well-known brands: MedExpress, Dermatica, ZipHealth, RocketRX, and Levity. A lot of our success is down to having our own pharmacies, manufacturers and products – spearheaded by leading in-house medical teams, researchers and pharmacists. Between 2023 and 2024 our global revenue tripled; £60m to £180m (300% year-on-year growth). We're looking to do the same in 2025; move into new territories, and further accelerate our growth journey. There’s never been a more exciting time to join HeliosX.
Where we’re going:
Over the next five years, you’ll support our goal to become a world‑leading healthcare partner, deepening our customer relationships, expanding into new countries, and diversifying our product portfolio to treat more conditions. You’ll be part of helping more people access prescription treatments and, most importantly, making personalised care better, quicker and easier for everyone.
Come be a part of making our dream of easier and faster healthcare a reality!
