A Creator-Led Boxing Fitness Platform

Overview

GoChamp is a custom mobile fitness app developed in partnership with IBF World Champion fighter Ivan Baranchyk. The goal was clear: build a branded digital experience that could serve as a new revenue stream by leveraging Ivan’s existing content workflows and fanbase. Rather than pulling users off of third-party platforms, GoChamp was designed to complement his online presence by turning fitness content into a productized offering.

The Challenge

Ivan was already producing high-quality workout content for social platforms. Our challenge was to take that momentum and translate it into a standalone app that provided real value to users while creating sustainable supplemental income. This meant building a mobile experience that could support structured workout flows, scheduling, user progression, and monetization, all while staying true to Ivan’s brand and voice.

Since this was not intended as a broad platform or marketplace, every feature had to serve a very specific audience: fans and followers looking for more in-depth, high-performance training programs built by a champion. The app needed to be intuitive, lightweight, and scalable without requiring Ivan or his team to manage complex technical workflows.

My Role

As Product Manager, I led the product from initial ideation through delivery. I worked closely with Ivan’s team to translate their goals into product requirements and with engineers and designers to bring the vision to life.

Key responsibilities included:

  • Structuring the app’s core user journeys, including onboarding, workout navigation, and subscription paywall
  • Coordinating sprint planning and prioritization across engineering, design, and QA
  • Building a backend content pipeline that allowed Ivan’s team to upload and schedule workouts with minimal effort
  • Developing LookerStudio dashboards to monitor app usage, workout engagement, and user retention
  • Running beta tests and internal QA to ensure quality before App Store and Play Store launch

Strategy

We positioned GoChamp as a creator-owned product that filled a gap in both control and niche focus. Through market research, I discovered that most influencer fitness apps were operated by third-party developers, limiting the creator’s ability to manage content or monetize effectively. I also noticed that while combat sports were trending in the fitness space, few apps focused exclusively on boxing. Most leaned into MMA, leaving an opportunity to build the first premium, boxing-specific fitness app led by a world champion.

On the development side, we scoped the MVP around three core pillars: smooth onboarding, structured training flows, and monetization. I led a lean cross-functional team including design, engineering, QA, and Ivan’s content team. We prioritized features that directly supported user value and revenue, pushing lower-priority ideas to the backlog to avoid unnecessary complexity or tech debt.

Our workflow emphasized speed and alignment. We used weekly retros, lightweight documentation, and Jira to keep execution tight. I built LookerStudio dashboards connected to GA to track onboarding completion, session engagement, and paywall conversion. These insights helped us identify friction early and iterate quickly.

By grounding our strategy in user value, creator control, and a clear market gap, we were able to launch a differentiated product that served both business and audience goals.

Outcomes

GoChamp launched on both iOS and Android, offering users a clean and focused fitness experience with video-based workouts, weekly schedules, and in-app purchases. Within the first few months, it achieved over 700 monthly active users. Gochamp established itself as a legitimate new revenue stream and is currently on track to achieving $40,000 in yearly revenue from subscriptions, all without a marketing budget.

The success of GoChamp demonstrated that elite athletes and influencers can convert their existing content habits into high-impact, monetized digital products with relatively low lift. More importantly, it showed that fans are willing to pay for deeper, more structured experiences when they are tied to a creator they trust.

Why It Mattered

GoChamp was more than a fitness app. It was a blueprint for helping creators turn their knowledge into productized value. The insights gained through building it, from onboarding flows to content scalability, directly influenced future projects including what would become CreatorHub, our white-labeled infrastructure for fitness creators at scale.
