500M+ downloads. 80M+ monthly users. A decade of building – and we’re still accelerating.
Flo is the world’s #1 health & fitness app worldwide on a mission to build a better future for female health. Backed by a $200M investment led by General Atlantic, we became the first product of our kind to reach a $1B valuation in 2024 – and we’re not slowing down.
With 7M paid subscribers and the highest-rated experience in the App Store’s health category, we’ve spent 10 years earning trust at scale. Now, we’re building the next generation of digital health – AI-powered, privacy-first, clinically backed – to help our users know their body better.
The job
We’re not chasing product–market fit. We’ve found it. Flo is used by 1 in 4 women aged 18–44 in the US. Last year, $200M raised. Earlier this year: 8.6M new installs, 2.8M user jump, That kind of scale doesn’t just happen. It’s engineered.
That’s where you come in.
We’re hiring Engineering Managers in London to lead a squad building the next generation of privacy-first, AI-powered health tools - and shipping them to a global audience.
