Do you want to be a part of enabling the next wave of innovation in communication protocols, building

sensors and cutting-edge hardware?

Does working with IoT devices, sensors, wearables, controllers which can seamlessly merge the digital

world with the physical world around us interests you?

Who we are?

We are working on IoT solutions that can be used to solve massive scale

problems by connecting things to people.

We are digitizing the electricity distribution grids to bring down network losses and ensure that

electricity reaches every house-hold.

We do this by building sensors, controllers, low power edge devices, connect and manage multiple

sensors with our ecosystem.

We are awarded as the Startup of the Year 2018 and our wireless technology in 2020,

has been awarded by India Smart Grid Forum, Government of India.

We has also been mentored by Cisco and Qualcomm in their startup accelerators.

We are a Venture Capital funded company and have raised our A1 round series in 2025.

We are looking for passionate electronics engineers to build the hardware that runs on edge computing,

system on chips, communicates with cloud servers, server-less containers, and everything in between.
