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  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.

At Healf, we’re not just a company, we’re a movement. Founded by two brothers whose own wellbeing journeys inspired our mission to empower others, Healf is built on grit, determination, and a shared understanding of the power of wellbeing.

Our culture is grounded in The Healf Standard—five principles that define how we work and win:

• We Work Harder Than Anyone Else:
  Building something that improves lives takes long hours, grit, and sacrifice, but we thrive on it. We all feel energised by what we’re building.
• Never Settle:
  We challenge the status quo and push ourselves to be better every day. We never settle for mediocrity or the idea that something can’t be done.
• Obsession Over Talent:
  Talent alone isn’t enough—relentless curiosity and a drive to grow set us apart.
• The Healf Lifestyle:
  We live what we preach—our personal commitment to wellbeing fuels our professional productivity.
• Stronger Together:
  Everyone owns their lane, but we run as a unit.
