About Zelos

The official calisthenics ranking app, built with and for the community.

Our Mission

Our mission is to unite the global calisthenics community through our platform. Where every athlete, from beginner to elite, can showcase their skills, climb the world's first global calisthenics leaderboard, and find inspiration through friendly competition and shared dedication.

We push each other to new heights through fair and inspiring challenge.

Dedication

We show up every day, committed to progress, discipline, and the pursuit of mastery.

Our Story

Zelos started with a simple question: how do I as a calisthenics athlete compare to others around the world? Currently, calisthenics is a niche sport with few competitions held around the world each year meaning not everyone can compete.

We wanted to change that and allow everyone to have the opportunity to compete and showcase their hard earned skills on a global scale. From the first prototype to public release, every feature has been shaped by the community of real athletes.

Hi, I'm Alex - Founder of Zelos

After completing my Master’s in Computer Science at Imperial College London, I spent three years working as a software engineer at a top-tier trading firm. It was an experience that taught me how to build reliable systems at scale. Alongside my career, I grew my YouTube and Instagram audience to over 20,000 by sharing my journey in tech, fitness, and calisthenics. Over time, I realized my true passion was creating for people at scale, I want to build for hunderds of thousands to millions of users. Zelos was perfect since it combines all my passions for engineering, community, and calisthenics.
