Full-stack App Developer

Build the Future of Wellbeing

Do Your Life’s Best Work

If modern wellbeing were redesigned from scratch, it wouldn’t live in a GP’s office or a cluttered supplement aisle. It would be digital-first, beautifully curated, and powered by data that actually helps you feel your best.

That’s what we’re building at  Healf -  an ecommerce platform at the intersection of personalised health and curated wellbeing. We connect customers with the world’s most effective products across  EAT MOVE MIND and SLEEP , and we’re just getting started.

We combine  culture-shaping storytelling ,  cutting-edge health tech (like our new blood testing platform,  Healf Zone ), and  a best-in-class product experience to help people build rituals that work.

Backed by investors behind  Soho House, Alo Yoga, Cult Beauty, and Innocent , we’re scaling fast and redefining how the world shops and lives well.
