Company: HeliosX Job title: Tax Accountant Location: London Ready to revolutionize healthcare, making it faster and more accessible than ever before? How we started: Founded in 2013 by Dwayne D’Souza, HeliosX was built on a simple but powerful idea: healthcare should be easier to access, faster to receive, and centred around the individual. From day one, we’ve grown without external funding; scaling profitably through technology, disciplined execution, and deep medical expertise. What started as a challenger idea has become one of the most significant healthcare platforms operating globally today. Where we are now: We’ve earned the trust of millions of people worldwide through category-leading products and well-known brands, including MedExpress, Dermatica, ZipHealth, RocketRX, and Levity. A key driver of our success is vertical integration; we operate our own manufacturing and proprietary products, led by in-house medical teams, researchers, and pharmacists at the top of their fields. In 2025, HeliosX treated more than 1.7 million patients globally and reached £781m in revenue, representing +337% year-on-year growth and cementing our position as the clear market leader in the UK. That growth translates into real-world outcomes: our weight-loss treatments helped patients lose 8.5 million kilograms of excess weight in 2025 alone, contributing to an estimated 1,300 fewer cardiac events. This is growth with measurable, life-changing impact at scale. Today, we operate across four international markets, with successful launches in Germany and Canada and continued expansion in the US. We were also recently recognised in the Sunday Times Top 100 fastest-growing tech companies, further validation of both our momentum and our ambition. Where we’re going: 2026 is another significant year for HeliosX. Our ambition is to surpass £1.1bn in revenue, continue expanding thoughtfully into new international markets and broaden our condition and treatment portfolio. As we scale, we're focused on building the technology, operational excellence and clinical capabilities that will support sustainable long-term growth. Joining HeliosX now means helping shape the systems, teams and products that will define the next chapter of digital healthcare.
