Rho Impact

Rho Impact is an American climate technology company that provides avoided emissions forecasting and impact data. Its core offering is Koi, a climate intelligence platform designed to help investors align capital with climate transition opportunities. The company positions itself at the intersection of data science, software engineering, and climate analytics, building infrastructure intended to move capital toward the solutions that matter most. Rho Impact grew out of Pit Rho, a predecessor company founded by Gilman Callsen. Pit Rho was acquired by General Motors, and Rho Impact was subsequently established as a successor venture. Gilman Callsen serves as Founder and Chairman of Rho Impact; he had been Founder and CEO/CTO of Pit Rho and previously co-founded MC10, a company developing stretchable, flexible electronics primarily for medical applications that was acquired by Medidata. Seth Sheldon, PhD, is a Founder of Rho Impact and formerly Director of Impact Analytics at Pit Rho / Rho AI. Sheldon was central to the methodology and scientific development of the CRANE tool, a free software tool for assessing the carbon reduction potential of emerging technologies and ventures. The company's team is composed of software engineers, data scientists, and practitioners. Rho Impact's work centers on avoided emissions forecasting — estimating the emissions that can be avoided when cleaner technologies and solutions displace higher-emitting incumbents — and on delivering impact data that investors and other decision-makers can use. Its platform, Koi, is aimed at the investment community, helping users evaluate climate transition opportunities and integrate climate intelligence into capital allocation. Rho Impact operates primarily from the United States and serves a global market of investors and organizations interested in climate-aligned finance. It is a private company. Its leadership combines deep experience in technology entrepreneurship, environmental science, and impact analytics, and its founders' prior ventures and tools — including Pit Rho, MC10, and CRANE — inform the company's approach to building climate data infrastructure.

Rho Impact is an American climate technology company whose roots trace to Pit Rho, a technology venture founded by Gilman Callsen. Pit Rho was acquired by General Motors, and Rho Impact was established as its successor. Gilman Callsen, who had been Founder and CEO/CTO of Pit Rho, became Founder and Chairman of Rho Impact. Before Pit Rho, Callsen co-founded MC10, a company that developed stretchable, flexible electronics primarily for medical applications and was acquired by Medidata; even earlier, he founded a company while in college that licensed electrochromic polymer technology for improving building energy efficiency. Seth Sheldon, PhD, is a Founder of Rho Impact and formerly served as Director of Impact Analytics at Pit Rho / Rho AI. Sheldon was central to the methodology and scientific development of the CRANE tool, a free software tool for assessing the carbon reduction potential of emerging technologies and ventures. He brought more than 15 years of experience in environmental science and impact analytics, having served as Technical Director for Greenometry and Environmental Data Lead for Lux Analytics Services Group. His work has been featured in outlets including Popular Science, the Wall Street Journal, the Los Angeles Times, Fortune, Fast Company, Greentech Media, E&E News, and Circle of Blue. Building on this foundation, Rho Impact developed Koi, a climate intelligence platform that helps investors align capital with climate transition opportunities. The company describes its team as software engineers, data scientists, and practitioners building the infrastructure that moves capital to the solutions that matter most. Rho Impact's focus on avoided emissions forecasting and impact data places it in the climate technology and climate finance space, serving investors and organizations that seek to integrate climate considerations into capital allocation. The company is privately held and operates primarily from the United States while addressing a global market.
