Blue Box Air
Blue Box Air is a Dallas-based cleantech company that restores and maintains commercial HVAC heat-transfer coils using a patented, enzyme-infused bio-treatment process. By cleaning coils from the inside out - with no downtime and no equipment removal - Blue Box improves airflow and heat transfer, cutting building energy consumption and carbon emissions while improving indoor air quality. Its Bio-Automation system keeps coils continuously clean, and the company markets a 'self-cleaning deep coil' that promises far greater heat-transfer surface area than conventional systems.
GlacierGrid
GlacierGrid (formerly Therma) is a San Francisco climate-tech company whose AI-powered Cooling Intelligence Platform combines IoT sensors, machine learning, and equipment controls to cut energy use, prevent food waste, and reduce carbon emissions across HVAC and refrigeration systems. Its customers include McDonald's, 7-Eleven, Marriott, Domino's, Dutch Bros, Taco Bell, Wendy's, Dunkin', Vail Resorts, and Cornell University.
Ryan Li
Ryan Li is the co-founder and CEO of Revert Technologies, a climate-tech company building AI-powered smart power adapters that hunt down 'phantom load' - the electricity devices waste while switched off. A chemical engineer turned energy operator, Li drilled deep-sea wells for Shell, designed green hydrogen plants, and ran Alibaba's US SMB business before building hardware in Maine that he describes as 'the easiest energy decision you'll ever make.' His company measures its own success in one unit: tons of CO2 removed.
Symetri USA
Symetri USA - formerly Microdesk - is an Autodesk-focused technology consultancy serving the architecture, engineering, construction and operations (AECO) industry. Founded in 1994 and acquired by Sweden's Symetri (an Addnode Group company) in 2022, it helps design, construction and asset-owner teams work smarter through BIM, VDC, digital twins, enterprise asset management and its own Naviate software line.

Founded in 2014 by Graham Rihn, it pairs a managed-services model with proprietary software and AI-powered smart cameras (via its 2022 acquisition of Compology) to meter, monitor and optimize waste streams. The company serves 14,000+ customers across all 50 states and has raised roughly $150M in venture funding.
Runwise
Runwise is a New York-based smart-building company that retrofits aging heating, cooling, water, and electrical systems with proprietary wireless hardware, sensors, and cloud software. Its platform learns each building's behavior and automatically runs core systems at the minimum needed, cutting fuel use 20-25%, lowering carbon emissions, and helping owners comply with climate laws like NYC's Local Law 97. Used in over 10,000 buildings across the U.S., Runwise has saved customers more than $100 million in energy costs and positions itself as the operating system for buildings still running on 1960s technology.
Vigilent
Vigilent is an Oakland, California company that uses artificial intelligence and machine learning to optimize cooling in data centers, telecom facilities and other mission-critical buildings. Its software pairs wireless sensors with self-learning control algorithms to automatically match cooling output to real-time heat load, cutting cooling energy use by 40 percent or more while eliminating hot spots and reclaiming stranded capacity. Founded in 2008 by MIT-trained control engineer Cliff Federspiel, the company has deployed across 1,500-plus facilities in 36 countries and counts Verizon, NTT, Digital Realty, IBM and Telus among its customers.
Mark Housley
