Plug & Play building infrastructures and energy systems. Automate, make informed decisions, and enforce cross-building policies. Founded as an incubation of a large research center (CNRS, Toulouse, France), we are an innovative start-up providing a standard-based cloud platform for IoT interoperability. We make it possible for IoT devices and applications to work together regardless of their vendors or origins. We maintain a catalog of software connectors, directly accessible through a user-centered interface, allowing anyone to integrate complex IoT systems in a few clicks. The platform offers seamless communications, semantic interoperability, and is designed to scale for massive IoT in various domains such as Smart Buildings, Smart Cities, and Factory of the Future. We have an innovative heritage (as part of previous work of more than 4 years in a large research center which incubated Sensinov), a commitment to open source, and an active involvement in emerging standards. We are uniquely positioned to provide a true open platform that offers a large panel of interworking possibilities and allows investment protection by avoiding lock-in.
