Thingful is a search engine for the Internet of Things, enabling discoverability across dozens of diverse networks. Founded in 2014 and headquartered in the United Kingdom, Thingful aims to enable an interoperable Internet of Things, where connected objects find and use each other's data with the active consent of their owners. The startup received a €100.00K grant investment from Open Data Incubator for Europe (ODINE) on 06 November 2015. Thingful provides access to a vast searchable index of public and private connected objects and sensors from various IoT networks and infrastructures such as energy, radiation, weather, and air quality devices, seismographs, iBeacons, vehicles, ships, aircraft, and animal trackers. The startup empowers IoT data owners to control how their data is used and enables them to make more valuable decisions through secure cross-domain IoT search and access. The company is actively involved in smart city, connected vehicle, machine learning, big data analytics, and citizen sensing initiatives. Thingful is currently working on enhancing its offerings and is also developing its API, which is currently in private beta. For those interested in accessing more information or the API, Thingful encourages getting in touch. Overall, Thingful is positioning itself as a crucial player in the IoT landscape, addressing the critical need for secure discoverability and interoperability between millions of connected objects globally.
