Emulate Energy
Emulate Energy is a Lund, Sweden cleantech company that builds white-label software turning everyday household devices - EV chargers, heat pumps, home batteries and solar inverters - into a coordinated, grid-ready fleet. Its platform lets utilities, retailers and grid operators connect, control and monetize distributed energy resources: cutting household bills, shaving grid peaks and unlocking flexibility-market revenue without asking customers to change tariffs or behaviour. Founded in 2020 on control-theory research from MIT and Lund University, Emulate runs live programs across Europe and the US.
Leitnium (Formerly YouSolar)
Leitnium, formerly YouSolar, is a Santa Clara-based clean-energy hardware company building the PowerBloc, a modular solar-plus-battery nanogrid that runs on a constant 400-volt DC architecture. Founded in 2010 by physicist Dr. Arnold Leitner, the company sells a plug-and-play private power plant that integrates solar panels, lithium-ion batteries, and optional grid or generator inputs into one intelligent, scalable system. The pitch is simple: give a home or small business its own always-on grid, so the lights never flicker even when the utility goes dark.
Public Grid
Public Grid is a climate-tech company building a software layer on top of the existing electric grid so households can switch to renewable energy and find savings without hardware, paperwork, or gatekeeping. Its platform sits on top of a user's utility account, brokers bulk green-energy contracts, applies local incentives, and surfaces cleaner, cheaper options in one click. Founded in 2022 (originally as Cottage Energy) and based in New York City, Public Grid says it serves 25,000+ households and is backed by Redbud VC and Hamilton Ventures.
