Reunion is the leading platform for clean energy tax credits and compliance. Since 2024, we have worked with major corporations to invest over $7 billion in clean energy projects, including some of the industry's largest tax credit transactions. We are a fast-growing and profitable company, and our expert 25-person team knows how to get things done and loves to move fast! Our founders, Billy Lee and Andy Moon, are second-time entrepreneurs and were early pioneers in solar tax equity and project finance. We have recruited an experienced team of early executives from SunEdison, SolarCity, Tesla, GoodLeap, and other leading clean energy companies. We have built a strong company culture which values collaboration and speed… while still having fun. In 2025, we launched Reunion PWA, a software solution that helps developers comply with prevailing wage and apprenticeship (PWA) requirements to unlock the full value of clean energy tax credits. Reunion PWA is rapidly gaining traction in the market, and we’re growing our team to accelerate adoption and expand to additional compliance offerings. Join us in the fight against climate change by helping renewable energy developers build faster!

Voltry is building power quality intelligence for modern grid and data center infrastructure. As compute density increases and electrical loads become more dynamic, traditional approaches to monitoring and managing power quality are no longer sufficient. Disturbances such as harmonics, distortion, and transient events increasingly affect reliability, efficiency, and long-term system behavior across large electrical environments. Our work focuses on understanding how modern compute loads interact with power systems, how disturbances propagate through complex electrical networks, and how these effects can be measured, modeled, and predicted. This includes research into signal behavior, system-level dynamics, and analytical approaches to interpreting power quality data at scale. Voltry is a research-driven company. We work at the intersection of power systems engineering, signal analysis, and data-driven modeling, with an emphasis on real-world infrastructure relevance. Our goal is to develop deeper visibility into power quality behavior and provide the foundations for more resilient and efficient electrical systems.
