i-SENS USA, INC.

What i-SENS USA, INC. does

i-SENS USA, INC. is the American subsidiary of South Korean medical device manufacturer i-SENS Inc., founded in 2000 by Dr. Geun Sig Cha and Dr. Hakhyun Nam. The US entity operates a direct-to-consumer e-commerce business out of Torrance, California, selling FDA-approved (21 CFR Part 820) blood glucose monitors under the CareSens brand (CareSens N, N Plus BT, N Feliz, and S Fit BT), blood ketone monitors under the KetoSens brand, the VetMate animal-glucose system, and the newer EZFAST line of Bluetooth blood pressure monitors and weight scales. Core technology is proprietary electrochemical biosensor IP — a 0.5 microliter sample-size, 5-second measurement sensor — with NeuralSync Sensing Technology using an artificial neural network in the S Fit BT for signal accuracy.

The business is supported by a recurring consumables model: test strips (the durable razor-and-blade stream), bundled with lancing devices, control solutions, and lancets, are sold à la carte or via a 5%-discount subscription. The SmartLog Mobile App (iOS/Android) and PC software integrate via Bluetooth with the BT-enabled meters for Glucose Ketone Index tracking and longitudinal diabetes management.

Commercially, i-SENS USA runs a content-driven DTC strategy — blog content segmented across Diabetic Health, Ketogenic, Metabolic Health, and Pets — backed by social media, email, and an Amazon marketplace listing. The parent i-SENS Inc. generates $160M USD in total revenue (50/50 own-brand vs. OEM), holds 30-35% Korean BGM market share, operates three manufacturing facilities producing 2.1 billion test strips annually, and exports to 110+ countries. i-SENS USA ships only to US addresses, has no insurance reimbursement for its meters, and has no disclosed US revenue, headcount, or enterprise contracts.
