Company profile
researched Aug 2026Mason offers an end-to-end platform for developing and delivering dedicated smart devices. The offering combines four layers: purpose-built hardware in multiple form factors (wearables, handhelds, tablets, and historically screens up to 55 inches); MasonOS, a customizable Android-based operating system stripped of consumer software bloat; device fleet management software with remote access and control, real-time monitoring, over-the-air updates and fleet health insights, backed by APIs; and operations and logistics services covering warehousing, kitting, shipping, white labeling, provisioning, global certifications and multi-carrier connectivity [0][1][3][4].
Customers access the platform three ways: a browser-based dashboard called the Controller, a command-line interface, and RESTful web APIs. Developers can sign up for a free account and order a Developer Kit that bundles a Mason device with platform services and developer tools. Devices can be organized into groups so that OS and app updates can be partitioned and rolled out incrementally; applications can be bundled and versioned with the OS or deployed independently [3]. The published device lineup includes the Mini 400 wearable (GPS, biometric sensors, fall detection and wellness metrics), Scan 600 and Smartphone 300 handhelds, the Radio 600T explosion-proof handheld with thermal imaging, the Body 600 5G body-worn video wearable, and the SmartTab 300 enterprise Android tablet, with stated 5+ year device lifecycles [0][1].
Mason positions its approach against traditional device management built on off-the-shelf hardware and fragmented tooling, citing manual configuration, inconsistent security updates and complex scaling as the problems it addresses [0][1]. Its customer onboarding path runs from application review and platform setup through pre-configured deployment, with a pilot stage before scaling [0][4].
