Its cloud platform turns a five-minute drone flight or remote satellite/LiDAR data into a to-scale 3D model accurate to within 1-3 inches, then generates layouts, shading reports, and permit-ready plan sets. Contractors use it from pre-sale proposals through post-sale final design to cut survey and design time by as much as 90% and reduce costly change orders on install day.
Cool Earth Solar
Cool Earth Solar is a California solar company with two lives: it launched in 2006 as a venture-backed clean-energy startup chasing utility-scale power with cheap, air-inflated plastic concentrator dishes, then evolved into a locally owned residential and commercial solar installer serving the Stockton-to-Placerville corridor. Today it designs, engineers, and installs solar power and battery storage systems in-house - no outsourcing - under CEO Rob Lamkin, and has been a recognized SunPower dealer, winning national and regional dealer awards.

Spun out of NRG Energy in 2018 by a team that met at MIT, Station A aims to make clean energy transactions as simple and transparent as an online marketplace, and counts large owners like Prologis, Walmart, CBRE, Nestle, and Goldman Sachs among its users.
Terrajoule Energy Inc
Terrajoule Energy is a Palo Alto cleantech company building modular, dispatchable solar power stations that deliver clean electricity around the clock without lithium-ion batteries. Its patented Dispatchable Solar Module (DSM) pairs prefabricated Linear Fresnel solar concentrators with a Steam Accumulator Energy Storage (SAES) system - storing energy as pressurized hot water in steel pressure vessels - and reciprocating steam piston engines to turn steam into electricity. The pitch is blunt: store energy in steel and water instead of rare metals, and undercut the cost of PV-plus-battery from day one. Founded by electrical engineer and serial hardware entrepreneur Stephen J. Bisset, Terrajoule raised an $11.5M Series A from NEA and Air Liquide's ALIAD, and was acquired by Environmental Clean Technologies Limited in December 2025.
BuildQ
BuildQ is an AI-native software and services company for capital-intensive infrastructure - energy, data centers and real estate. Founded in 2024 by attorney and former renewable-energy operator Maryssa Barron, the platform centralizes a project's documents, financials and contracts, then uses AI to run due diligence, surface risks and obligations, and produce investor-ready memos and data rooms. The pitch, in Barron's words, is 'TurboTax for project finance': turn the slow, six-figure, thousand-page grind of financing a clean-energy project into something faster and cheaper. Less than a year after launch, BuildQ reported 300+ projects, 10+ gigawatts of capacity and $150M+ in deal flow on the platform.
Plural
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.
