SpanIO, based in San Francisco, is developing products to reduce the cost and complexity of adopting distributed energy systems. We are a group of engineers with a passion for building products that can deliver a positive impact on the environment while enhancing consumer experience. We believe that developing intelligent hardware and software that provides visibility and control at the edge-of-grid will be transformational to the energy sector.

We are backed by domain experts in energy, software, hardware, and consumer finance. We are leveraging our teams collective experience in power generation, energy conversion, controls, and system integration to develop our core product focused on enabling the rapid adoption of renewable energy.
