Wiliot

Wiliot develops battery-free, postage-stamp-sized sensor tags called IoT Pixels together with the network infrastructure and cloud software needed to turn their signals into supply chain data. The tags harvest energy from ambient Wi-Fi, cellular and Bluetooth radio signals and transmit readings such as location, temperature, humidity, light, fill level, motion and proximity. Each IoT Pixel contains an ARM Cortex-M0+ processor core, Bluetooth Low Energy connectivity, about 1 kB of non-volatile memory and antennas for both communication and energy harvesting; dual-band variants add ISM band connectivity. Off-the-shelf bridges and gateways wake nearby pixels with radio signals, collect their data and forward it to Wiliot's cloud platform.

The company positions its offering as a "Physical AI" or ambient IoT platform in which continuous sensing data is processed by purpose-built AI and machine learning models to produce alerts, analytics and dashboards. Packaged solutions cover inventory intelligence (scan-free cycle counting), automated receiving, reusable asset tracking, automated shipment verification and temperature/dwell-time monitoring, targeted at grocery, general retail, post and parcel, and quick-service restaurant operations. Wiliot contrasts its continuous, scan-free approach with RFID and barcode systems, which it characterizes as creating choke points at fixed read points.

Wiliot's tags have been applied to shipping crates used by agricultural suppliers, to visibility over perishable goods and inventory, and to consumer-facing use cases such as sensing when a consumable is near end of life or how many wash cycles a garment has had. The company has stated intentions to extend into pharmaceuticals and apparel.

Founding story

Wiliot was founded in 2017 in Israel by Tal Tamir, Yaron Elboim and Alon Yehezkely, who previously led millimeter-wave company Wilocity and sold it to Qualcomm in 2014; the founding team consisted of wireless engineers from that company.

Business model

Wiliot supplies low-cost IoT Pixel tags and network hardware together with a cloud platform; press coverage of its 2021 financing described a planned transition to a SaaS "sensing as a service" model plus licensing of its chip designs to third-party manufacturers so others can build additional tag form factors.

Revenue is generated through licensing of the company's cloud software and software-as-a-service subscriptions for the data and analytics derived from its sensors, alongside a chip hardware licensing model.

Traction

Named customers and deployments include Israeli supermarket chain Shufersal, its first large public customer in June 2022, and Royal Mail, which digitized core delivery assets for asset visibility. Case studies cover online and grocery retailers. Walmart deployments were reported in late 2025. The Japan Research Institute has run food-loss reduction trials using Wiliot tags. The company cites over 180,000 assets located in one solution area and inventory accuracy above 99%.

Latest developments

Announced a collaboration with AT&T Business addressing international enterprise demand for Physical AI in supply chains and a partnership with CISC to advance high-volume production of its battery-free IoT Pixels. Press reports in October and November 2025 described Walmart deploying sensors to support inventory tracking and AI initiatives.
