Diamond IQ Baseball is the verified recruiting platform built for the modern baseball player — where real data meets real opportunity. VERIFIED. NOT SELF-REPORTED. Every stat, measurable, and performance metric on Diamond IQ is tied to verified sessions from certified training facilities. Exit velocity, bat speed, spin rate, 60-yard dash — all confirmed by the facilities that measured them, not just entered by the player. When a college coach or scout sees a DIQ profile, they can trust what they're reading. YOUR DIQ SCORE Every player earns a Diamond IQ Score — a single, dynamic number that reflects your verified measurables, game performance, competition level, and physical tools. It updates automatically as you log games and complete verified sessions. Your DIQ score is your recruiting currency. FOR PLAYERS Build a complete, verified recruiting profile in minutes. Log game stats after every outing. Connect with certified training facilities for HitTrax, Rapsodo, and other verified sessions. Share your public profile link with college programs. Get discovered by coaches and scouts actively searching for players like you. FOR COACHES Manage your roster, verify player stats, and identify guest players for open spots. Build lineups, track player development, and stay connected with the athletes you're developing for the next level. FOR SCOUTS & RECRUITERS Search and discover verified players by position, class year, location, exit velocity, and more. Build your watchlist and pipeline. Every player you find on Diamond IQ has data you can actually rely on. FOR TRAINING FACILITIES Run HitTrax and Rapsodo sessions that go directly onto a player's verified profile. Your facility badge travels with every session you verify — putting your brand in front of the coaches and scouts who see your players' profiles.

College programs are identifying players earlier than ever, and the athletes who get noticed are the ones with a complete, credible digital presence — not just a highlight reel.
