Sky Labs Inc.

Market position

Sky Labs states that CART BP pro is the world's first ring-type cuffless blood pressure monitor to be officially incorporated into an official hypertension guideline, the 2026 Korean Society of Hypertension hypertension management guidelines (6th edition). Its clinical materials reference alignment with European Society of Hypertension recommendations for daytime and nighttime blood pressure tracking.

Cuffless, ring-form-factor measurement enabling automatic long-term and nighttime blood pressure tracking, backed by validation against invasive arterial line data and standard sphygmomanometry, reported consistency across skin colors, and inclusion in an official national hypertension guideline.

Technology

The device measures blood pressure from the finger using a photoplethysmography (PPG) sensor that detects subtle blood flow changes in finger vessels, with a proprietary deep-learning algorithm converting the signal into personalized systolic and diastolic blood pressure values. The company reports algorithm validation against invasive arterial (A-line) blood pressure data, trained on 4,185 subjects and 320,535 A-line BP samples collected in an operating room with 10% reserved for validation, yielding mean error/SD of 0.98/6.97 mmHg for SBP and 0.52/4.38 mmHg for DBP. Separate validation against a standard sphygmomanometer reported mean error/SD of 0.16/5.90 mmHg (SBP) and -0.07/4.68 mmHg (DBP), with correlations of r = 0.94 (SBP) and r = 0.95 (DBP), and no performance differences by skin color. A 24-hour comparison against ambulatory blood pressure monitoring (ABPM) reported daytime-nighttime BP change tracking with mean error ± SD of -3.39 ± 5.86 mmHg (SBP, r = 0.73) and -3.74 ± 4.72 mmHg (DBP, r = 0.75). The measurement platform supports smartphone, tablet and PC.

Go-to-market

The company runs parallel professional and consumer channels from its website, with an inquiry form for hospital adoption of CART BP pro. It builds clinical credibility through validation studies and presence at medical conferences, including exclusive symposiums at the 35th European Society of Hypertension congress (ESH 2026) in Gdansk, Poland and the British Cardiovascular Society annual meeting (BCS 2026) in Manchester, UK, and a presentation of its data platform business at the 9th Digital Biomarkers in Clinical Trials Summit in Basel, Switzerland. It has also supported the American Heart Association's 'Established Investigator' program.

Two customer groups: hospitals and healthcare professionals who adopt CART BP pro for patient blood pressure monitoring and clinical use, and consumers using CART BP for personal blood pressure tracking. The data platform business targets pharmaceutical clinical trial use.
