No peer‐to‐peer structure
Platforms offered only house‐centric betting, not direct friend‐to‐friend challenges
Esketchers developed an app that brings sports fans together through friendly competition and rewards. It allows users to challenge friends on live games, lock in predictions, and compete on leaderboards without cash betting.
Outcome: Winners earn coins that can be used to enter sweepstakes for authentic sports memorabilia and exclusive collectibles.
Start your Ai-First ProjectFistBump is a social app for sports fans who love competition and rewards. Instead of cash betting, users challenge friends directly on live games, lock in picks, and climb the leaderboards. Winning earns you coins to enter sweepstakes for authentic sports memorabilia and exclusive collectibles.

Fans weren't just making picks. They were trying to challenge friends, lock predictions, track leaderboards, and earn real rewards without a proper system.
Every challenge was manual, slow, and trust- dependent, leading to disputed outcomes, lost coins, and frustrated users.
Every existing platform forced users to bet against a house or algorithm. There was no way to challenge a specific friend, post a pick to a group, or compete on a leaderboard without cash. Fans had no real social connection, no ability to lock picks directly with peers, and no system to prevent double‐spending or automate payouts.
During live games, users had to manually track results, settle disputes, and handle transfers leading to frustration, lost trust, and abandoned challenges.
Platforms offered only house‐centric betting, not direct friend‐to‐friend challenges
Winners and losers had to calculate and transfer coins manually, with no automation
No real‐time chat, no leaderboards, and no way to build ongoing rivalries
We engineered a highly scalable, live-synchronized social gaming platform that centralizes live sports data feeds, automated peer-to-peer wagering workflows, secure coin transactional architecture, and interactive social features into a unified mobile experience.
Custom challenges on live games supporting Money Line, Spread, or Over/Under mechanics.
Instant end-of-game processing driven by automated data feeds to calculate payouts and transfer coins.
Double-spend prevention by instantly locking both users' coins the exact moment a challenge is accepted.
An automated house bot that auto-accepts challenges so users always have an opponent to play.
A coin-wagering loop combined with a separate sweepstakes engine for physical sports memorabilia.
Every layer was built for real‐time competition, secure coin locking, and automated challenge resolution.
