MULTIPLYING WHAT PEOPLE ARE CAPABLE OF

We build and scale technology-first well-being brands that help people train smarter, recover faster, and live better.
Originally founded as WithU in 2020, 10XU was created by experts in technology and well-being – Steve Clarke and Kaleigh Frost  – who shared a simple belief...

‍movement has the power to change lives.

‍We began with one product and one focus: WithU – a breakthrough business-to-business, audio-first fitness app – designed to make elite coaching accessible to everyone, anywhere. 
Then, the world changed.
The pandemic reshaped how people lived, worked, and moved. The wellness industry shifted overnight. Many fitness apps did not survive.
‍
But where others paused, we accelerated.

‍ We knew well-being wasn’t just about exercise. It was also about the other pillars that support modern life like connection, recovery, and travel.
As new ideas and products emerged, we became more than a single brand. So we scaled to 10XU.

The name reflects our core philosophy:
to multiply what people are capable of.

‍10X = exponential growth.
U = the individual.
Each product solves a different part of the modern well-being equation – movement, training, travel, recovery, and social sport.

Individually, they’re powerful.

Together, they drive more impact – forming a shared platform that supports health, wellness, and performance
across daily life.

Our Team
We build and scale technology-first well-being brands that help people train smarter, recover faster, and live better. We believe progress should be exponential — for our brands, our users, and the wellness landscape.
Exponential growth. We don't do incremental — we aim to multiply impact at every level.
The individual. Every product, every decision, starts and ends with you.
