Verse is a San Francisco-based energy infrastructure software company, co-founded in 2022 by former Fluence Chief Digital Officer Seyed H. Madaeni and former Fluence/AMS commercial executive Matt Penfold. Its AI-powered platform Aria gives enterprises and data centers a centralized hub to manage electricity spend and intelligently dispatch behind-the-meter battery and solar assets, while its Dispatch Intelligence product lets AI data centers bypass interconnection queues and come online up to three years earlier. It is already used by Fortune 500 companies to manage complex energy portfolios.

Voltus, founded in 2016 and headquartered in San Francisco, runs a distributed energy resource software platform and virtual power plant that aggregates batteries, cooling systems, backup generation and flexible commercial, industrial and residential loads, dispatching them into nine wholesale power markets across the US and Canada. It uses AI-driven load forecasting and revenue optimization, and its Bring Your Own Capacity program aggregates flexibility for utilities and large power buyers including AI data centers. It manages about 8.5 GW across 22,000+ sites.

Apollo Atomics is an MIT Department of Nuclear Science and Engineering spinoff redesigning the largest component of a conventional pressurized water reactor - the steam generator - into a person-sized Compact Steam Generator, shrinking overall reactor footprint by roughly 40x. It is developing three factory-built, truck-transportable systems (10 MW A-10, 50 MW A-50, 300 MW A-300) deployable in under 24 months, using existing NRC-licensed commercial-grade fuel and supply chains rather than novel reactor technology. Target customers are data center operators, industrial offtakers, and utilities, aiming for roughly 3 cents per kWh.
