Review Analytics
Access game data and insights instantly
The Challenge Facing Youth Baseball
80% of umpires quit within 2 years. Too little training, too much abuse.
Higher levels of baseball rely on data previously the domain of expensive equipment. HeyBLU levels the playing field.
Umpire Shortage
Youth umpires face constant pressure with minimal support, leading to massive turnover rates.
Limited Access to Data
Coaches and players lack the analytics tools available to pros, limiting development opportunities.
Inconsistent Zones
Without objective feedback, improving strike zone consistency and player development is nearly impossible.
Preparing for the Future of Baseball
MLB is rolling out Automated Ball/Strike (ABS) technology in 2026, where players can challenge calls and technology makes the final decision. HeyBLU brings ABS-level strike zone precision to youth and amateur baseball today, helping umpires train, coaches develop players, and athletes prepare for the data-driven game they'll face at higher levels.
