What Prevayl does

Prevayl is a UK-based wearable technology company that develops clinical-grade ECG smart sportswear under the SmartWear™ brand. The company's core offering is a compact rechargeable sensor (the Prevayl Sensor) that slots into a smart underband within textile garments — including T-shirts, sports bras, tanks and long-sleeve tops with knitted electrodes — and streams up to 1,000 data points per second of chest-based biometric data over Bluetooth to the Prevayl mobile app (iOS/Android). Data is uploaded to a cloud platform hosted on AWS within the European Economic Area, where proprietary on-device ML and firmware algorithms derive recovery scores (BodyCheck™), training zones, energy expenditure, guided breathing and a 'train, rest, or progress' recommendation engine. The flagship consumer proposition is sold exclusively through the company's own UK e-commerce storefront (shop.prevayl.com) as 'Smart Training Packs' priced £210–£225 (bundling sensor + garment + free lifetime app) and standalone Performance Wear apparel at £24.99–£39.99. The companion app is free with no subscription, making revenue entirely transactional hardware sales.

Beyond consumer hardware, Prevayl operates a parallel IP-licensing business (Prevayl Innovations Limited) that markets a 250+ patent portfolio — covering textile sensing, body area networks, on-device intelligence, AR/VR integration, industrial worker monitoring and charging infrastructure — for licensing, acquisition or co-creation to wearable OEMs across smart clothing, watches, rings and meta products. The company is venture-backed by Stonebridge (£7.5M seed in June 2021; a subsequent ~$12.5M round in August 2022) and supported by research partnerships with Bangor, Loughborough and University of East London. Distribution is UK-only for products (EEA for the app), with last-mile delivery via Yodel and co-marketing through fitness app Fiit. As of 2025, the operating entity (Prevayl Limited) is under the management of Joint Administrators, signalling insolvency-driven restructuring.

Revenue model

1. Hardware sales — Sensor + SmartWear bundles: One-time sale of "Smart Training Packs" (sensor + smart garment + free lifetime app access) and individual smart garments (Smart Sports Bras, Smart T-Shirts, Smart Long-Sleeves, Smart Tanks) priced £70–£225. The Prevayl Sensor is also sold as a one-time purchase ("One-time purchase. Unrivalled real-time data to fulfil your potential.") at £150 RRP.
2. Performance Wear apparel sales: Direct e-commerce sales of non-smart performance apparel (leggings, shorts, base layers, vests, jackets) priced £24.99–£39.99 — a complementary line to SmartWear bundles.
3. App — Free, no subscription: Prevayl App and cloud platform are offered free with no subscription; the app is included as "FREE lifetime Prevayl App membership" with each Smart Training Pack purchase. Revenue is therefore captured entirely via hardware sales rather than recurring software subscription.
4. IP licensing / acquisition (Prevayl Innovations): Prevayl Innovations (a separate IP-licensing entity from Prevayl Limited) explicitly offers to "License our Intellectual Property," "Acquire Intellectual Property," and "Create new Intellectual Property using our expertise" across wearable product types (smart clothing, smart watches, smart rings, meta products). Represents a potential B2B licensing/royalty revenue stream tied to its 250+ patent portfolio.

Core offering

Prevayl designs, develops and sells clinical-grade ECG-enabled smart sportswear consisting of a reusable chest sensor (Prevayl Sensor), garment-embedded knitted-electrode apparel (SmartWear™), a companion iOS/Android app, and a cloud platform that turns physiological data into training insights. The company also sells non-smart performance apparel, offers bundled Smart Training Packs, and operates a separate IP-licensing business (Prevayl Innovations) that licenses its 250+ patent portfolio and Body Area Network technology to third parties.

Product overview

Prevayl operates a connected-wardrobe platform built from four tightly integrated offerings: the Prevayl Sensor (clinical-grade ECG wearable hardware), the SmartWear™ smart-clothing line (T-shirts, tanks, long-sleeve tops and sports bras with integrated knitted electrodes), the Prevayl mobile App (iOS/Android) and the Prevayl cloud Platform that underpins it. The Prevayl Sensor snaps into a discreet pocket within any SmartWear™ garment and streams biometric data over Bluetooth to the App, which uploads it to the cloud Platform to return personalised BodyCheck™ and FitnessCheck insights, training zones and guided-breathing recommendations. These products are sold both as standalone items (SmartWear single items, Performance Wear) and bundled as Smart Training Packs that pair a garment with the Sensor and a lifetime App membership. Alongside this consumer offering, Prevayl Innovations monetises the company's 250+-patent IP portfolio (textile sensing, body-area networking, on-device intelligence, AR/VR, charging, industrial monitoring) by licensing or selling patents to wearable-device makers.

Broad incumbents

• Garmin: Garmin dominates the multisport GPS watch category with built-in optical HR, advanced training metrics, and broad global distribution. It competes with Prevayl for the same elite-athlete and serious-amateur endurance/fitness segment, but at a much larger scale and with a wrist-based form factor.
• Apple (Apple Watch): Apple Watch now includes clinical-grade ECG, blood-oxygen, and recovery/HRV-style insights via the Health app. As a global consumer-electronics incumbent, it represents the principal competitive threat to a premium ECG wearable at a comparable or lower effective price point.
• Fitbit (Google): Fitbit, now part of Google, sells mainstream fitness wearables with heart-rate, ECG (Sense line), and recovery features at mass-market price points. It competes for the same 'fitness-conscious consumer' segment Prevayl targets and represents the dominant distribution-scale threat in the category.

Direct peers

• Whoop: Whoop sells a screenless, subscription-based fitness/recovery wearable that emphasises HRV, recovery, and strain scoring. While Whoop uses a wrist-worn form factor rather than a chest-embedded ECG sensor, it directly competes with Prevayl for the same 'fitness-conscious consumer who wants clinical-grade recovery insights' segment and the same athlete-ambassador-led marketing model.
• Polar Electro: Polar is a long-established sports wearables company whose heart-rate monitoring heritage (including chest straps and optical sensors) and elite-athlete partnerships closely mirror Prevayl's positioning. Polar's Ignite, Vantage, and H10 chest-strap product lines compete in the same training-load and recovery insight category.
• Oura: Oura sells a smart ring that delivers recovery, sleep, and readiness scores from biometric signals, marketed on a recurring membership model. Although the form factor is a ring, Oura directly targets the same 'lab-grade biometric insight for the general consumer' positioning Prevayl claims.
• Sensoria Fitness: Sensoria develops textile-sensor smart garments (notably smart socks and running apparel) and a developer SDK for health-monitoring wearables. It is a direct smart-clothing peer with comparable technology and consumer/clinical dual-use applications.
• Hexoskin: Hexoskin makes biometric smart shirts with embedded textile sensors for heart rate, breathing, and activity monitoring, sold to consumers, athletes, and researchers. It is the closest direct smart-garment peer to Prevayl's SmartWear line, with a similar ECG/breathing-rate technical proposition.
• Myant (SKIIN): Myant produces textile-computing smart apparel with biometric sensing across heart rate, temperature, and motion, and sells a connected-wardrobe concept very similar to Prevayl's. It is a credible smart-clothing direct peer and a potential partner or competitor in the same connected-garment category.

Emerging players

• Empatica: Empatica makes medical-grade wearable sensors (EpiMonitor, Embrace) with FDA-cleared biometric monitoring. It overlaps with Prevayl in clinical-grade health wearables but is more established in regulated medical applications rather than consumer sports.
