HeatSense - Athlete Insights

What HeatSense - Athlete Insights does

HeatSense is a US-based athlete safety and performance technology company that sells wearable sensors and accompanying software for real-time monitoring of core body temperature and heart rate during athletic activity in extreme heat. The company targets three customer segments: individual youth athletes and their parents, coaches and athletic trainers who manage roster-wide heat exposure, and schools or athletic programs seeking institutional heat-safety solutions. Headquartered in Austin, Texas, HeatSense launched in 2025 and operates with a team of 1–10 employees.

The core product is a $399 hardware kit combining a lightweight wearable thermal sensor (powered by CORE heat flux technology validated within ±0.3–0.4°C against gold-standard ingestible temperature capsules) with a Polar H10 heart rate strap, a carrying case, and a USB-C charger. Sensor data flows into the HeatSense mobile app for individual athletes and parents, and into a web-based Team Dashboard that gives coaches and athletic trainers roster-wide real-time visibility. The company's intellectual layer is its proprietary 4 Rs framework (Readiness, Response, Runway, Recovery), which structures pre-activity baselines, real-time monitoring, predictive runway projections, and post-exercise recovery tracking, and includes a composite Heat Strain Index score.

HeatSense operates a hybrid go-to-market: product-led self-serve e-commerce for individuals, a consultative enterprise field-sales motion for team and school deployments (with demo days and onboarding support), and a community-led motion driven by parent referrals through a "Make an Impact" program. Revenue comes from one-time hardware sales plus recurring monthly ($4.99) or annual ($49.99) subscriptions, with a 1-month free trial and a current World Cup 2026 promotion offering $40 off. The company emphasizes scientific credibility through extensive educational content, guidance from thermoregulation researchers, and content partnerships with the Korey Stringer Institute and the Remy Hidalgo Memorial Foundation.

Core offering

HeatSense sells a wearable thermal sensor kit (HeatSense Kit, $399) that pairs via Bluetooth with a smartphone app to continuously measure core body temperature, skin temperature, and heart rate in real time. A web-based Team Dashboard extends the platform for coaches and athletic trainers to monitor roster-wide heat response. Access to real-time insights, alerts, and WBGT data is unlocked through a $49.99/year or $4.99/month membership subscription, after a 1-month free trial.

Product overview

HeatSense is a performance and wellness platform combining a wearable thermal sensor, a mobile athlete app, and a team dashboard for real-time heat response monitoring in athletics. The core offering includes the HeatSense Thermal Sensor (which tracks core body temperature, skin temperature, and heart rate), the HeatSense App (delivering real-time insights and alerts to individual athletes and parents), and the HeatSense Team Dashboard (enabling coaches and athletic trainers to monitor roster-wide heat response). Accessories include the HeatSense Athlete Case and Polar H10 Heart Rate Strap. Access to the platform's monitoring features requires either an annual membership ($49.99/year) or monthly subscription ($4.99/month). The system is powered by CORE thermal technology and supports the company's Heat Readiness framework built around the 4 Rs: Readiness, Response, Runway, and Recovery.

Partnerships

Four partnerships are on record, tiered core and minor.

• CORE (Kayser-United Technologies)coreTechnology or IntegrationHeatSense is powered by CORE's heat flux sensor technology. CORE's wearable heat flux sensor delivers precise, real-time core body temperature data. The technology is validated against ingestible temperature capsules and trusted by elite cycling and triathlon athletes.
• Polar (H10 Heart Rate Sensor)coreTechnology or IntegrationThe Polar H10 Heart Rate Strap and Sensor are included in the HeatSense Kit as the heart rate monitoring component. The Polar H10 is a professional-grade chest strap heart rate monitor that pairs via Bluetooth with the HeatSense app.
• Korey Stringer InstituteminorStrategic or Co-development PartnerHeatSense links to the Korey Stringer Institute's heat stroke treatment protocols on their blog. KSI provides evidence-based resources for heat illness prevention and treatment that support HeatSense's educational content.
• Remy Hidalgo Memorial FoundationminorStrategic or Co-development PartnerThe Remy Hidalgo Memorial Foundation was created after 16-year-old Remy died from exertional heatstroke during a 2020 football practice. The foundation advocates for practical heat readiness tools and education. HeatSense publishes their story to honor their loved one and accelerate awareness.

Expansion highlights5 records

Direct peers

• Polar: Polar is the manufacturer of the H10 heart rate strap bundled in the HeatSense kit and a long-standing supplier of HR monitors for endurance athletes. It is both a direct integration partner and a competing wearable vendor in the same athletic monitoring category.
• Catapult Sports: Catapult provides wearable athlete tracking (GPS, HR, load management) for professional and elite teams via the Vector and S5 platforms. It targets the same coach/athletic-trainer buyer that HeatSense's Team Dashboard serves, with deeper enterprise penetration.
• STATSports: STATSports sells GPS-based team athlete monitoring vests and dashboards used by elite and youth sports programs. It competes for the same team-level monitoring budget and decision-maker that HeatSense targets with its Team Dashboard.
• CORE (Kayser-United Technologies): CORE manufactures the heat-flux sensor that powers HeatSense and also sells its own consumer heat-monitoring products directly. It is simultaneously a critical technology partner and the closest direct competitive comparable.

Broad incumbents

• Garmin: Garmin sells a broad portfolio of fitness and multisport wearables, including HR and skin-temperature features, with deep distribution into running, cycling, and outdoor athletics. It overlaps with HeatSense on athlete biometric monitoring but as part of a much wider product portfolio.
• Whoop: Whoop is a subscription-based wearable platform focused on strain, recovery, HRV, and sleep for athletes. It does not specialize in core body temperature but is the dominant premium wearable subscription comparable and the most likely feature-competitor.
• Apple (Apple Watch): Apple Watch includes heart rate, skin temperature sensing (Series 8+), and a broad fitness ecosystem with massive installed base among athletes. It is the most likely platform incumbent to add credible heat-strain features as a free capability.
• Oura: Oura makes a subscription-based smart ring focused on sleep, recovery, HR, and skin temperature trends. While not sport-specific, it competes for the same health-conscious athlete subscription dollar and has skin-temperature sensing that overlaps with HeatSense's category.

Emerging players

• Embr Labs: Embr Labs makes the Embr Wave, a personal thermal comfort wearable for hot/cold sensation. It is an adjacent consumer thermal wearable that targets overlapping use cases (heat comfort) but not core-temperature monitoring of athletes.

Others

• Korey Stringer Institute: The Korey Stringer Institute is the leading academic and advocacy body for exertional heat illness prevention, referenced by HeatSense as a content partner. It shapes the regulatory and clinical landscape in which HeatSense operates but does not sell competing products.
