TL;DR

KEEPON builds AI “twins” of fitness creators, enabling them to offer 1:1 online coaching at scale. We’re hiring our first backend/AI engineer to turn our working prototype into a production-grade platform launch to 4 million fans in 3 months!

You’ll work directly with founders including a former MIT PhD in AI and a repeat fitness-tech founder with an 8-figure exit.

⚠️ Warning: This is early, fast, and intense — but the upside and ownership are exceptional.

Location + start date

• NYC (in-person) — We will work together from a physical space in New York City
• Start: By January

Company Description

Creators have millions of followers, and 1:1 (human) coaching doesn’t scale. Fitness apps are usually generic and low-touch; 1:1 coaching is expensive and time-limited.

KEEPON is the “operating system” for creator-led AI coaching:

• Creators get an AI twin that coaches their fans like them
• Fans get a highly personalized coach + accountability system

Early proof:

• We already built a working “Coach Sam” prototype (our founder’s AI twin) with meaningful real usage (23k coaching conversations and 6k workouts tracked since June 2025)
• We have creators with 8 million combined followers committed and ready ****to launch on the platform — this means tens of thousands of users can arrive very quickly once things work.
