Wearable device for nervous system regulation with research-grade sensors

Wellness and Fitness Services Amsterdam, North Holland 51–200 employees Founded 2020 Privately Held

NOWATCH builds a wearable focused on stress resilience and nervous system support, with embedded sensors and mobile companion apps. The tech stack reveals a hardware-software integration play: low-level embedded work (C, Zephyr, Bluetooth Low Energy optimization) paired with native iOS and Android clients (Swift/SwiftUI, Kotlin/Jetpack Compose), plus active adoption of testing frameworks (Appium, Espresso) — indicating maturation toward production rigor. Current hiring (6 engineers, mostly senior, across Netherlands) is concentrated in core platform work: next-generation embedded firmware, battery optimization, and on-device ML deployment.
