Scalvy
Scalvy is an Austin-based power electronics company building a modular, software-defined platform called the Power Neuron that distributes power conversion and control to the edge of each battery pack instead of routing it through a single centralized block. The approach targets three power-hungry markets - AI data centers, grid-scale energy storage, and electric mobility - promising higher usable energy, ultra-high efficiency, and faster development cycles. Founded in 2022 by Mohamed Badawy, the company raised a $13.9M Series A in March 2026, bringing total funding to roughly $17M.
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.
