// IoT ecosystem

From sensor
to insight.

We design the hardware, write the firmware, build the cloud backend, and ship the mobile app. One team, zero integration headaches.

Real-time telemetry
Sub-second data streaming from edge devices to cloud with custom LoRa, WiFi, and LTE protocols.
OTA firmware updates
Deploy firmware to thousands of devices simultaneously. Rollback protection, delta updates, staged rollouts.
Hardware security
Secure boot, encrypted storage, TLS 1.3 end-to-end. Built with industry security standards from day one.
