The Company

We are building products to enable the rapid adoption of renewable energy. As more distributed energy resources like solar and storage come onto the grid, it’s increasingly important to be able to improve the technology that sits between the grid, the home, and those distributed energy resources. Our smart panel replaces the electrical panel to become the centre for connected power in the home. With the company, homeowners receive all the safety features of a standard panel with revolutionary insights and edge-of-grid controls through our mobile app. Installers are likewise able to commission panels with a dedicated app to facilitate their process.

The company is a startup based in the SOMA neighbourhood of San Francisco. We are a small, diverse team of creative thinkers. We value open communication, teamwork, and a make-it-happen attitude – no job is too big or too small. We strive to make a change by imagining what the future could be and building a product to complete that vision. We are looking to grow our team with talented people who are on the same mission to shape the future of energy.
