Industries we've proven this layer in
Real builds that leaned on this layer.
Pulled from our case-study library — same AI/human split shown in full, industry context included.
On-Device Early Fall-Detection Wearable
US-based aging-in-place / digital-health wearable startupA wearable analyzes motion data locally to identify movement patterns associated with potential falls, without continuously transmitting raw sensor data to the cloud.
Cold-Chain Shipment Monitor
US-based logistics / pharmaceutical supply-chain technology companyA connected monitoring device tracks temperature and environmental conditions in transit and storage, alerting when conditions move outside defined limits.
Multi-Sensor Water-Leak & Freeze Guard
US-based home-protection / smart-home startupA connected home-protection sensor fuses multiple environmental signals to detect water leaks, freezing conditions and other potentially damaging events.
What people ask before scoping this layer.
Which RTOS / wireless stacks do you work with?
FreeRTOS, Zephyr and bare-metal on the RTOS side; BLE, Wi-Fi, LoRa, Zigbee and cellular on connectivity, chosen based on your power and range constraints, not by default. When a device is gateway- or compute-class rather than coin-cell, we take the same work to embedded Linux — board support, kernel and driver work, and the update path on top.
How do you handle OTA safely?
Signed, rollback-capable OTA pipelines with staged rollout — the update path is designed alongside the firmware, not bolted on after v1 ships.
What's the AI/human split in practice here?
AI scaffolds drivers and protocol-stack boilerplate; a senior firmware engineer owns real-time timing guarantees and every power-critical code path.
Can you extend battery life on an existing product?
Yes — power profiling and firmware-level tuning is a common standalone engagement when hardware is already locked.
This layer rarely ships alone.
