What XLNTbrain does

XLNTbrain, LLC is a Maryland-domiciled software company founded in 2012 by neurologist Dr. Harry Kerasidis to address gaps in concussion detection, documentation, and recovery management across youth, scholastic, collegiate, and amateur sports. The company operates XLNTBrain, a web-based concussion management platform accessible from any internet-connected computer, paired with native iOS and Android mobile applications for sideline use. The platform integrates preseason concussion education, a baseline neurocognitive test (measuring reaction time, attention, inhibition, memory, processing efficiency, and executive function) compared against the company's normative database, SCAT6-conformant sideline assessment and balance testing, daily symptom checklists, and a 5-step progressive exertion recovery protocol that culminates in return-to-play clearance and a complementary Academic Care Plan for return-to-learn.

The product architecture includes a GraphQL API layer (introduced in v3.4.4 in 2024) and integrations with third-party systems including Healthy Roster (athletic training workflows), Athletic Trainer Systems (ATS), August Schools (student information systems via SFTP), and Stripe (individual subscription billing), reflecting an explicit platform-and-integrations strategy. Pricing is quote-based annual subscription sold through enterprise field sales to schools, colleges, and sports organizations, supplemented by per-athlete self-pay via Stripe. Distribution is dual-channel: enterprise direct sales with a "Book a Demo" CTA to institutional buyers, plus self-serve via mobile app stores to athletes and guardians.

The company employs 11-50 people, has not disclosed external funding, and is founder-controlled. Recent commercial activity includes a partnership with Capital Rugby Union for the 2025-2026 season — the first disclosed entry into organized rugby — alongside ongoing content marketing through the XLNTinsights blog and earned media in NFL, CBS Sports, Athletic Business, and other outlets. Primary customer segments are athletes and guardians, school officials (coaches, athletic trainers, athletic directors, administrators), medical professionals, and sports organizations; only two named end customers (Boston Cannons of Major League Lacrosse and St. Mary's College of Maryland) are publicly disclosed in source data.

Direct peers

• ImPACT Applications: ImPACT is the leading computerized neurocognitive concussion testing platform used across schools, college athletic programs, and professional sports leagues. It directly competes with XLNTBrain's baseline testing, sideline assessment, and recovery tracking modules for the same school/sports organization buyer.
• HeadCheck Health: HeadCheck offers a concussion management platform combining baseline testing, sideline assessment and return-to-play workflows targeted at school districts, clubs and sporting organizations. Overlaps with XLNTBrain on enterprise concussion SaaS, mobile sideline tools and parent/staff communication.
• Concussion Vital Signs (CNS Vital Signs): Concussion Vital Signs is a web-based neurocognitive assessment and concussion management suite sold to schools, sports medicine clinics and athletic programs. Competes with XLNTBrain's baseline testing and SCAT-based protocol modules.
• C3 Logix: C3 Logix provides a comprehensive concussion management platform including neurocognitive baseline testing, balance testing and mobile sideline apps for athletic trainers. Direct overlap with XLNTBrain on the integrated testing/sideline/recovery workflow sold to K-12 and college athletic programs.

Emerging players

• Quadrant Biosciences / Concussion Sentinel: Quadrant Biosciences offers saliva-based biomarker and digital tools for concussion assessment. While their core IP is diagnostic rather than software workflow, they intersect with XLNTBrain's clinical evaluation layer and pitch into the same athletic-trainer and sports-medicine buyer.
• Prevent Biometrics: Prevent Biometrics makes a smart mouthguard that detects head impacts in real time, sold to sports teams for objective concussion screening. They sit in an adjacent slot to XLNTBrain's paper-/app-based sideline assessment and represent a sensor-based alternative that could displace baseline testing workflows.

Broad incumbents

• Catapult Sports: Catapult is an established athlete monitoring and performance analytics platform used by professional and collegiate sports teams worldwide. While broader than concussion alone, Catapult increasingly bundles health-and-wellness modules that overlap with XLNTBrain's medical-professional and recovery-tracking workflows.
• Atlas (PlayerData / athlete-monitoring SaaS): Broader athlete-performance and injury-monitoring SaaS vendors serving teams, leagues and federations globally. They may not specialize in concussion but their medical-professional modules compete for the same athletic-trainer budget that XLNTBrain targets.

Others

• Healthy Roster: Healthy Roster is a central athletic-training EMR that integrates with XLNTBrain (per the v3.1.2 release) to ingest concussion reports. While not a head-to-head competitor, it sits in the same school-athletic-trainer procurement ecosystem and could choose to bundle a competing concussion module.
• SportsWare (ATS partners): SportsWare and other Athletic Trainer System (ATS) platforms integrate with XLNTBrain for concussion record exchange. As ATS vendors are mission-critical to athletic trainers, they are both partners and potential competitors in the broader sports-medicine documentation space.
