What Pmgrow does

Pmgrow (PMGROW Corp.) is a South Korea-based private company operating across the EV battery circular economy, with activities spanning battery pack solutions, subscription and care services, real-time safety monitoring, government-certified battery inspection, and second-life energy storage products. Its core technology platform is WattSafe, a real-time battery safety notification service that uses the WattBox in-vehicle data terminal to collect more than 20 battery parameters (voltage, current, temperature) and produces a proprietary Status Data Score (SDS) safety index through an algorithm trained on over 80 million kilometers of real-time operational data. The product portfolio also includes SafePass (access control gating parking and charging based on real-time vehicle safety ratings), WattEver (residual battery performance certification), and the R-ESS line (Home, C&I, EV Station) that repurposes end-of-first-life EV batteries into stationary storage. Pmgrow operates a Battery Green Cycle Camp inspection facility in Pohang and holds a unique regulatory designation as South Korea's first private reusable battery safety inspection agency, authorized by the Ministry of Trade, Industry and Energy's National Institute of Technology and Standards to issue official safety certificates for post-consumer EV batteries being repurposed into energy storage and other second-life applications.

Revenue is generated through multiple streams: subscription-based B2B safety notification services to parking operators, apartment managers, and transport fleets (bus and taxi); a freemium B2C WattSafe app for individual EV drivers (free for the first two months, then subscription); government-authorized battery safety inspection and certification fees; battery data services; and hardware sales of second-life R-ESS products. The go-to-market combines enterprise field sales anchored by the ADT Caps (SK Shieldus) partnership, which provides a path to Tmap Parking and FMS integrations, with product-led growth via WattSafe on the Play Store and App Store, supplemented by international distribution through the TUV NORD certification partnership covering Southeast Asian markets.
