Fantasy Tennis App Discovery: Tech Stack, Costs & Development Roadmap

Fantasy Tennis App Discovery: Tapping Into $42 Billion Industry

How strategic technical decisions made a solo-built app competitive in Polymarket's ecosystem

The Opportunity

Tennis is one of the most globally followed sports, with year-round tournaments, iconic Grand Slams, and millions of engaged fans across continents. Unlike seasonal team sports, tennis operates almost continuously, creating constant opportunities for fan interaction.

‍
The fantasy sports market alone exceeds $42 billion globally, yet tennis remains one of the least explored segments within it.

Team composition: BA, Solution Engineer, PM & UX Designer

Timeline: 4 weeks

Planned release date: Q4, 2026

Client's idea

The client came to us with an idea to build a fantasy tennis platform that would deepen fan engagement and give meaning to following tournaments and players throughout the year.
‍

The concept was based on real-world tennis performance:
‍

Users would create fantasy teams made up of professional players
Earn points based on match statistics
Compete in public or private leagues
‍

Unlike existing solutions, the product was not meant to be tied to a single tournament or event, but instead support continuous play across the tennis calendar.

A key part of the vision was education. The client wanted users to discover more about tennis players - their careers, performance patterns, and risks rather than focusing only on top-ranked stars.

During discovery, it became clear that fantasy tennis is an underserved niche. Current products fail to support year-round play, and do little to help fans understand the broader tennis ecosystem.

What our Client Says

They provided excellent advice at the outset of the project. I described what I was trying to accomplish and what I thought it was looking to hire them for. They counseled me to consider a slightly different path that was more cost-effective and efficient. We followed their advice and it proved to be the correct course of action.

Additionally, they are based primarily in Ukraine and I’m in the US, but the working partnership was seamless.
