Zero Homes is a Denver-based technology company focused on streamlining residential electrification. Its mobile app lets homeowners create digital scans of their properties, receive virtual assessments, and obtain customized plans and instant quotes for heat pumps, insulation, EV chargers, and other energy-efficient upgrades. The platform then connects users with a curated network of contractors, functioning as an end-to-end digital marketplace. Zero Homes is actively installing projects in Colorado, Massachusetts, Minnesota, Illinois, and California. Management plans to enter additional markets in 2026 while broadening product offerings and deepening contractor coverage. The recent Series A financing brings the company’s known capital raised to $16.8 million, funding the next phase of product and geographic expansion.

Hexium is building a laser-powered process to separate lithium-6 from lithium-7 using an adapted atomic vapor laser isotope separation (AVLIS) technique. The company was founded by Charlie Jerrott and Jacob Peterson after they identified a shortage in fusion fuel supply chains and had been operating in stealth. Hexium’s system uses picometer-precise, relatively low-power lasers to ionize lithium-6 in vapor clouds, draw the ions to charged plates, condense them, and package the isotope for sale. Hexium plans to sell lithium-6 to fusion companies for tritium breeding and reactor shielding, while selling the remaining lithium-7 to conventional nuclear operators as a cooling-water additive. Over the coming year the company will use its seed funding to build and run a pilot plant and, if successful, replicate the design modularly to produce tens to hundreds of kilograms of lithium-6. The team emphasizes small-footprint facilities that can be parallelized to achieve economics at modest scales.

Glacier develops low-cost robotic arms guided by computer vision to identify over 30 material types and automate sorting at materials recovery facilities (MRFs). Its robots have been deployed in San Francisco, Los Angeles, Chicago, Detroit, Phoenix and Seattle. The company offers robots as outright purchases or via lease-to-own, and provides training, spare parts and maintenance packages to customers. Glacier also sells a data product that gives MRFs, consumer-products companies, and government agencies insights into the waste stream and recycling performance. The startup, described in the article as six years old, plans to expand its robot fleet to more municipalities to address labor shortages and improve recycling rates. Financially, Glacier recently closed a $16 million Series A to support that expansion. Glacier is a Bay Area recycling robotics startup whose core products are a sorting robot deployed in recycling facilities and an AI scanner that tracks materials and packaging fate. Amazon is piloting the AI scanner to understand what happens to packaging after it reaches consumers. The company says it works with customers in 10 states and is forming partnerships with brands, Fortune 500 companies, and government agencies. Glacier has collaborated with the City of Phoenix and received a grant from the Michigan Department of Environment to support further deployments. Co-founders include CEO Rebecca Hu and Areeb Malik. The startup recently closed a new $7.7M funding round co-led by Amazon and NEA. Glacier builds compact, low-cost recycling robotics and automation systems designed for space-constrained sorting facilities. The company emphasizes three advantages—low cost, small size and easy install—and has conducted pilots and deployed its first commercial system at a facility in Los Angeles. Founded in 2019 and operating in stealth until the announcement, Glacier’s team combines AI and robotics engineers with founders Areeb Malik (formerly a software engineer at Facebook) and Rebecca Hu (formerly at Bain & Company). The team’s experience includes self-driving excavators and forklifts, extraterrestrial mining robots, humanoid disaster-response robots and AI models for medical detection. Glacier has opened preorders for its first commercial system and plans to use new funding to increase headcount and accelerate commercial deployment. The company positions its product as an alternative to larger, more expensive systems in the recycling space.

Lydian has developed PIVOT™, a full‑stack, modular production platform that integrates proprietary reactors, catalysts, process design, software, and balance‑of‑plant into factory‑built modules for synthetic aviation fuel. The platform is designed to cut project capital costs by more than 50% versus competing technologies, operate flexibly with intermittent renewable electricity, and reduce lifecycle greenhouse gas emissions by up to 95%. Lydian produces ASTM‑approved, drop‑in sustainable aviation fuel from captured CO2 and hydrogen and is positioning PIVOT to enable faster, lower‑cost deployment of synthetic fuel projects. The company operates a tonne‑scale pilot plant at its Boston R&D Center of Excellence and plans a commercial demonstration facility targeted for 2028 with first full‑scale commercial deployment expected in 2030. Financially, the company completed a $43 million Series A to support commercialization and deployment activities.

Antora Energy develops and deploys factory-built thermal batteries that store low-cost electricity as heat in insulated solid-carbon blocks and deliver that energy as heat or power on demand. The company says its systems can store energy for multiple days, avoid supply-constrained critical minerals, and be deployed faster than conventional multi-year projects. Antora recently brought one of the largest battery storage projects online—a 5 gigawatt-hour system in South Dakota that moved from construction to energy delivery in under 12 months—and expanded its San Jose factory into a three-building manufacturing campus. The company reports a growing pipeline of signed agreements with hyperscalers and industrial customers and states its deployments have created and supported hundreds of U.S. manufacturing and construction jobs. With the $550 million Series C, Antora plans to expand production capacity, establish a second U.S. manufacturing hub, and strengthen its domestic supply chain. The company positions its technology as a tool to deliver affordable, reliable energy at scale to industry, data centers, and the grid.
