Sky Labs

What Sky Labs does

Sky Labs Inc. (주식회사 스카이라브스) is a South Korean AI-based healthcare platform company founded in 2015 and headquartered in Pangyo, Seongnam. It develops and commercializes a family of cuffless, ring-type photoplethysmography (PPG) blood pressure monitors under the CART brand, anchored by the proprietary PPG2BP-net deep learning algorithm that converts finger PPG signals into systolic and diastolic blood pressure readings with clinical-grade accuracy. The portfolio spans CART BP (consumer, MFDS 제인 24-734호), CART BP pro (medical-grade 24-hour ambulatory BP monitor eligible for Korean national insurance code E6547, MFDS 제인 23-5024호), CART ON (hospital inpatient ward solution integrating with Seers Technology's thynC platform and hospital EMRs, MFDS D 제인 25-4043 호), and CART PLATFORM (CE-MDR certified end-to-end bundle of device + mobile app + cloud server + clinician web viewer). Earlier generations include CART-I, CART-I Plus, and the CES 2025 AI Innovation Award-winning CART VITAL.

The company operates a hybrid go-to-market: direct-to-consumer e-commerce (own Cafe24 storefront, Naver Smart Store, Coupang) plus physical pop-up retail (Hyundai Department Store Pangyo), combined with B2B sales to hospitals and clinics through exclusive pharmaceutical distribution partnerships — Daewoong Pharmaceutical for CART ON and CART BP pro in South Korea, Otsuka Pharmaceutical for CART BP pro in Japan (signed February 2026), and OMRON Healthcare for global commercialization of CART BP (strategic partnership and OMRON Ventures investment, November 2025). Additional channels include a digital-health integration with Kakao Healthcare's Pasta app and selection for the Korea Disease Control and Prevention Agency's national cohort study. Revenue mechanics are primarily hardware sales (one-time purchase, with 102 bundled uses per CART BP pro device) bundled with companion software/cloud services; pricing is not publicly disclosed. As of mid-2026, the platform reports 1,700+ Korean hospitals and 150,000 cumulative CART BP pro prescriptions, and CART BP Pro has been included in the Korean Hypertension Clinical Guidelines (May 2026) as a world first for a cuffless ring-type monitor.

Core offering

Sky Labs designs, manufactures, and sells a portfolio of ring-shaped cuffless blood pressure monitors that use optical photoplethysmography (PPG) sensors combined with proprietary deep learning algorithms (PPG2BP-net) to continuously measure systolic and diastolic blood pressure without an arm cuff. Products span consumer self-monitoring (CART BP), clinician-prescribed 24-hour ambulatory BP measurement (CART BP pro), automated hospital inpatient vital sign monitoring (CART ON), and a CE-MDR certified global platform configuration (CART PLATFORM) with companion mobile app, cloud server, and clinician web viewer.

Product overview

Sky Labs is an AI-based healthcare platform company (founded 2015) that delivers a multi-product portfolio of cuffless, ring-type photoplethysmography (PPG) blood pressure monitors spanning consumer, clinical-professional, hospital-inpatient, and global regulated-market segments. The portfolio is structured as a platform-plus-modules architecture centered on the CE-MDR certified CART PLATFORM (device + mobile app + cloud server + medical web viewer), with four primary offerings: CART BP for direct-to-consumer 24/7 personal BP monitoring, CART BP pro as the clinician-prescribed 24-hour ABPM solution under Korean insurance code E6547, CART ON for automated hospital inpatient ward vital-sign monitoring, and CART PLATFORM as the EU/global regulated configuration. Earlier generations CART-Ⅰ (CE-MDD 2020) and CART-Ⅰ Plus (MFDS 2021, CES 2022 Healthcare Innovation Award, Red Dot 2021) preceded the current lineup, while CART VITAL earned a CES 2025 Artificial Intelligence Innovation Award. All products share Sky Labs' proprietary PPG2BP-net deep learning algorithm validated against invasive arterial line and ISO 81060-2 auscultation standards, with clinical-trial-validated accuracy for time-series BP, atrial fibrillation detection, and personalized 28-day calibration.

Direct peers

• Oura: Consumer smart ring leader with a medical-grade health platform positioning. Direct competitor in the smart ring form factor and a named co-player in the Medical Smart Rings market alongside Sky Labs, competing for the same health-conscious consumer segment.
• OMRON Healthcare: Global leader in blood pressure monitoring devices and Sky Labs' exclusive global distribution and strategic partner (with OMRON Ventures investment). Competes in BP monitoring while simultaneously commercializing CART BP, making it both a critical partner and a potential competitive threat via its own cuffless R&D.
• Withings: Connected health device company offering smart blood pressure monitors, hybrid smartwatches, and health-oriented wearables. Comparable in offering clinically validated consumer health hardware, multi-condition monitoring, and B2C + B2B distribution models.
• iHealth Labs: Connected health device company with a portfolio of smart blood pressure monitors, wearables, and other remote patient monitoring devices. Comparable as a clinically oriented, hardware-plus-app consumer and clinical health monitoring company competing for similar B2B and B2C channels.
• Aktiia: Swiss startup that has commercialized a CE-marked cuffless continuous blood pressure monitor using optical PPG technology on the wrist. One of the most direct competitors in cuffless continuous BP, addressing the same clinical and consumer segments as Sky Labs' CART BP pro.

Broad incumbents

• Samsung Electronics: Samsung's Galaxy Ring and broader Galaxy Watch health platform include biometric monitoring and are explicitly named alongside Sky Labs in the Medical Smart Rings market. A broad incumbent with vastly greater consumer reach, marketing budget, and R&D that could pressure Sky Labs' consumer ring segment.
• Masimo: Global patient monitoring leader with continuous non-invasive monitoring technology (including its own PPG-based hospital solutions). Comparable in providing continuous, clinical-grade monitoring technology and competing for hospital and inpatient monitoring budgets.
• Apple: Apple Watch includes PPG-based heart health features and blood pressure monitoring capabilities in development. A broad incumbent with the consumer brand power and developer ecosystem that could rapidly capture the cuffless BP smart wearable category if it ships.
• Philips (Patient Monitoring): Global leader in hospital patient monitoring, including continuous vital sign solutions and EMR-integrated inpatient workflows. Comparable in addressing the hospital inpatient monitoring use case targeted by Sky Labs' CART ON.

Emerging players

• BioIntellisense: Continuous remote patient monitoring company using wearable biosensors for in-hospital and at-home vital sign monitoring. Comparable in pursuing continuous wearable vital sign capture, with a focus on clinical and hospital channels similar to Sky Labs' CART ON inpatient solution.
