About

Built by a coach. Engineered like infrastructure.

TGP started as the founder’s coaching business hitting the ceiling of what spreadsheets and Slack could carry. The platform is what we wished existed.

Story

From a coaching business to an operating system.

The Growth Project started as a coaching business. Sub-coaches, programs, client check-ins, weight logs, sales calls — all stitched together with Trainerize, Notion, Slack, Zapier, and a Google Sheet that broke every Sunday. By 30 clients, the system was a bottleneck, not a backbone.

Rather than buy four more tools that didn’t talk to each other, we built one. TGP is the operating system we wanted: sub-coach hierarchy with engagement scoring, a workout builder with a 1,300-exercise library, an offline-first client app, audit-logged everything, and a talent marketplace for when the team needs to grow. Built solo, end to end.

Today TGP is in private beta with a small group of head coaches running 30 to 80 client operations. We open access to new operators every two weeks. If your coaching business is at that ceiling and you’d rather build the system than rent five of them, apply.

A SaaS company’s worth of infrastructure. From a single developer.

Principles

What this platform is for, and what it isn’t.

  • 01

    Coaching is operations, not personality.

    Most coaching software is built for solo trainers selling workouts. TGP is built for operators with teams. The product reflects that — every primary surface assumes more than one coach, more than one program, more than one client cohort.

  • 02

    The product is the proof.

    We don’t have testimonials yet. We have an offline-first mobile app, an audit-logged backend, a talent marketplace, and a private beta. If the platform doesn’t speak for itself, the testimonials wouldn’t help.

  • 03

    Apply, don’t sign up.

    TGP isn’t built for everyone running coaching. We apply-gate so we can confirm fit before billing — and so the operators inside the platform are surrounded by other operators, not tire-kickers.

Apply when you’re ready.
