What's cooking today?
One industry. A decade of building in it.
We don't do fitness on the side. It's all we do, and that changes everything about what you get.
Turn followers into subscribers
You've built the audience. Now you need the platform: workout delivery, subscription billing, nutrition tracking, and a community your followers can't get on Instagram.
See how we work with creatorsDesign the digital experience your members expect
Multi-location management, member data integration, tens of thousands of daily users. Your members use consumer fitness apps every day. They expect that same quality from you.

Workouts, nutrition, analytics, notifications. Each one tailored to the client's business and audience.

Let's talk about your platformWhy Extenova is different.
A decade focused exclusively on fitness technology. Here's what that gets you.
Fitness only
No dating apps. No dog toys. No e-commerce side projects. Every platform, all fitness. That's how we know your market better than you expect.
Hundreds of thousands of users of pattern recognition
We've seen onboarding, retention, and monetization across every platform we've shaped. We know what works, and what kills a fitness app in 30 days.
CEO-led, every project
You work directly with Pankaj, our CEO. Not a project manager. Not an account executive. The person who has shaped every one of our platforms.
4+ year partnerships
We don't hand off and disappear. Our average client relationship is 4+ years. The best features come in year two. That's when the real patterns emerge.
Design-led, built in-house
We don't hand you templates. Every platform is designed to reflect your brand, your goals, your workflow, and your users' expectations, so the end result feels like yours, not ours. Design and engineering, all under one roof.
Responsive communication
You talk directly to the people shaping your platform. When something needs a decision, you get an answer, not a status update. No ticket queues. No weekly emails that say nothing.
How we work
Two rooms. The thinking room is where the real decisions happen. The making room is where they come to life.
Where the real decisions happen.
Executing a plan you've approved.
