## About

Founded in 2015 in Seongnam, South Korea, Sky Labs Inc. operates as a healthcare technology company that specializes in developing cuffless, ring-type blood pressure monitors for continuous and automatic health tracking. In December 2025, Sky Labs Inc. raised KRW 11.5 billion in pre-IPO funding from investors IMM Investment, QUAD Investment Management, Atinum Investment, Devsisters Ventures, and GU Equity Partners, valuing the company at KRW 211.5 billion post-money. The CEO, Jack Lee, leads the firm as it expands its market presence.

Sky Labs Inc. specializes in advanced cuffless, ring-type blood pressure monitors, notably its flagship product, the CART BP. This device allows for automatic, continuous blood pressure measurement through a ring, providing insights into fluctuations and is designed for everyday use. The CART BP employs photoplethysmography (PPG) signals analyzed through deep learning algorithms for accuracy. While primarily marketed in South Korea, the company aims to extend its reach to North America and Europe, targeting both consumers and healthcare providers.

Sky Labs Inc. generates revenue through direct sales of its CART BP medical devices to consumers and healthcare institutions. The products are available via retail partnerships and direct purchases, with potential subscription models for ongoing data monitoring. The pricing reflects the advanced technology and healthcare applications, complemented by partnerships with hospitals for bulk purchasing agreements, enhancing accessibility and market presence.

Following the recent pre-IPO funding of KRW 11.5 billion raised in December 2025, Sky Labs Inc. plans to prepare for eventual public listing. In addition, the funding will support clinical research and development, as well as global marketing and distribution efforts, with a focus on entering new international markets including North America and Europe.
