Chariot Defense is a South San Francisco defense-technology company building hybrid-electric power systems for the battlefield. Its Amphora platform delivers quiet, high-density, software-controlled power to distributed military hardware - drones, sensors, radios, electronic-warfare and directed-energy systems - so that energy never becomes the limiting factor in a fight. Founded in 2024 by former Anduril and Archer engineer Adam Warmoth, the company raised a $34M Series A led by Andreessen Horowitz in February 2026, bringing total funding to roughly $41-42M, and has fielded its systems with the U.S. Army and the Defense Innovation Unit.
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.
Plural is a San Francisco fintech building the financial operating system for infrastructure - a programmable execution layer that tokenizes real-world energy assets like solar farms, battery storage, and data centers. It targets the 'missing middle' of clean energy: sub-$100M projects too small for traditional project finance but too big to ignore. By pairing smart-contract automation with a registered broker-dealer, Plural lets developers raise capital faster and lets institutional and alternative investors underwrite, monitor, and trade cash-flow streams from the electron economy.
Critical Loop is an industrial power company founded in 2023 by former SpaceX, Tesla and Palantir engineers. It deploys modular, relocatable battery-storage microgrids - paired with its software-defined controller, Cygnus - to give factories, data centers, airports and other grid-constrained sites reliable power in weeks instead of waiting years for utility upgrades. The company raised a $26M Series A in April 2026, bringing total committed funding to $49M, and operates a fleet of control nodes across California.
Hover Energy is a Dallas-based clean-energy company that builds patented Wind-Powered Microgrids - rooftop arrays of compact 36 kW turbines that turn a building's own edge into a sail, combined with solar, storage, and an AI-driven control stack. The system is designed to offset most or all of a building's power use on site, delivering resilient, behind-the-meter electricity to commercial, industrial, and data-center customers. Paired with IBM's watsonx and Maximo software and scaled through joint ventures like EverOn Energy, Hover pitches an Energy-as-a-Service path to what it calls 'real zero.'
