OptiRTC (Opti)

Opti (OptiRTC, Inc.) is a Boston-area software company that makes stormwater infrastructure smart. Its cloud platform - built around a technique it calls Continuous Monitoring and Adaptive Control (CMAC) - links sensors, valves, and weather forecasts to actively move water in ponds, tanks, and detention systems before, during, and after storms. Spun out of engineering consultancy Geosyntec in 2014 and acquired by global infrastructure firm Aliaxis in 2022, Opti helps cities, utilities, developers, and engineers cut flooding, reduce combined-sewer overflows, and improve water quality with existing infrastructure rather than costly new construction.
