A working prototype is a beginning. Liverpool’s publicly backed innovation company supplies early money, specialist help and introductions to get the business moving too.
Phoenix Tailings Found a $1 Billion Business Hiding in Mining's Trash
The Massachusetts startup began with buckets of mine waste in a backyard. Seven years later, it has commercial metal shipments, a strategic trading partner, and a conditional $500 million government loan - but the real test is whether a tiny refinery can become industrial infrastructure on schedule.
The Family Office That Treats Capital Like a Contact Sport
Wasson Enterprise is a 16-person family office with an operator's reflex: write the check, open the network, then help with the awkward work of growing. Its portfolio stretches from pharmacy automation to recycled plastic, but the common product is practical leverage.
Rekosistem
Rekosistem is a Jakarta-based clean- and climate-tech company that manages Indonesia's fragmented waste supply chain end to end. Through a network of Reko Waste Stations, app-based pickup services, and material recovery hubs, it collects, sorts, and channels waste from households and businesses back into the circular economy. Founded in 2021 by Ernest Layman and Joshua Valentino, the company serves 90,000+ households and 200+ enterprise clients, processes roughly 4,500 tonnes of waste per month, and raised a US$7M Series A in 2025 led by Saratoga Investama Sedaya and K3 Ventures.
Steve Huang
Steve Huang is the founder and CEO of KiWi New Energy, a Taiwan-born, San Mateo-based startup building what he calls an operating system for global renewable energy. A serial green entrepreneur with more than 15 years across the semiconductor and solar value chain, Huang went from NVIDIA and public silicon-wafer ventures to a near-total collapse when Chinese rivals undercut his micro-inverter business, then rebuilt around an AI-driven energy datacenter that matches clean supply with retail and small-business demand in real time.
David Mather

Under his leadership NxLite launched its L80 low-E sputter coating, opened a 45,000-square-foot manufacturing center in Canton, Michigan, and raised a Series A that expanded to $13.1 million to scale production of coatings aimed at cutting the energy lost through windows.
Ian Lowe
Ian Lowe is the founder and CEO of Arduro Sustainable Rubber, a clean-technology company turning end-of-life tires and waste rubber back into high-value raw materials. A former JPMorgan financial controller and Piper Jaffray project-finance banker, Lowe spotted a University of Louisville research project posted online and built it into a company commercializing a patented chloramine devulcanization process that recovers rubber, carbon black and processing oils at a roughly 95% reuse rate. Arduro's first product, ELDARIX r1000 recovered carbon black, is aimed at tire and rubber manufacturers looking to cut carbon footprints while keeping performance.
James Metropoulos
James (Jim) Metropoulos is the founder and CEO of Blue Box Air, a Dallas-based clean tech company that has built a patented, bio-automated way to clean and restore the heat-transfer coils inside commercial HVAC systems. He founded the company in 2016 in Southern California and moved its headquarters to Deep Ellum, Dallas in 2020. His enzyme-based process tackles a century-old problem in the HVAC industry - coils that were never truly cleanable - and in doing so cuts building energy use, improves indoor air quality, and lowers carbon emissions. Blue Box counts clients such as MGM Resorts, UC Berkeley, General Motors, LA Children's Hospital and the Golden State Warriors, and reports having restored tens of thousands of coils while saving hundreds of millions of kilowatt-hours.
Brillouin Energy
Brillouin Energy is an Emeryville, California clean-technology company developing thermal energy systems based on Low Energy Nuclear Reactions (LENR). Its patented Controlled Electron Capture Reaction (CECR) process uses small amounts of hydrogen, nickel and electricity to generate heat via its Hydrogen Hot Tube (HHT) reactor and proprietary Q-Pulse control system, with helium as a negligible byproduct and no carbon emissions or radioactive waste. Founded in 2009 by Robert Godes, the company aims to commercialize licensable, ultra-clean heat for industrial process, district energy and distributed power applications.
Porifera
Porifera builds forward osmosis membrane systems that concentrate beverages and treat wastewater without heat or pressure. Its proprietary PFO technology removes water from juices, coffee, beer and wine while preserving flavor, aroma and color - cutting energy use up to 80% versus conventional evaporators. In 2025 the company launched Draftfox, a beer concentration and Microkeg dispense system that shrinks a keg by 6x.
Dan Cook
Dan Cook is the CEO, Co-founder, and Investor at Lyten Inc, a San Jose-based deep-tech company pioneering 3D Graphene supermaterial and next-generation lithium-sulfur batteries. With over three decades spanning General Motors, NeXT Computer (under Steve Jobs), Bay Networks/Nortel, and private equity at Cerberus Capital, Cook pivoted to found Lyten in 2015 around a serendipitous discovery: trying to turn methane into clean hydrogen, the team accidentally created a revolutionary 3D graphene material. Under his leadership, Lyten has raised over $1.2 billion, shipped lithium-sulfur A-samples to automotive and military customers, announced the world's first lithium-sulfur gigafactory in Reno, Nevada, and in 2025-2026 acquired significant Northvolt assets across Europe to become one of the largest battery manufacturers on the continent.
Hover Energy
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.'
Chris Griffin
Chris Griffin is the co-founder and CEO of Hover Energy, a Dallas company that builds patented Wind-Powered Microgrids - arrays of 36kW rooftop turbines paired with solar and storage that let commercial buildings make their own clean power. An aerospace engineer turned Wall Street financier turned clean-energy entrepreneur, Griffin spent roughly two decades chasing the same idea before one of his rooftop systems rode out 105 mph gusts during Hurricane Ian. He has since taken the technology international, with a Royal Navy installation in Liverpool and a joint venture to scale deployments for blue-chip clients.
