StormSensor develops a climate technology platform that precisely maps water movement through urban sewer, storm, and coastal systems. The company deploys a scalable network of sensors combined with cloud-based software and machine learning analytics, offering real-time visibility and data to monitor stormwater infrastructure. This approach enables adaptive planning and management of urban flooding, thereby mitigating hazardous risks and reducing the impact of pollution and property damage.
Erin Rothman founded StormSensor in 2015, driven by the critical insight that increasing climate volatility demanded a data-driven solution for managing urban water infrastructure. Her vision was to modernize an antiquated industry by providing cities with the tools to proactively address challenges like rising sea levels, intensifying storms, and aging infrastructure, which contribute to flooding and sewage overflows.
The company's solutions are utilized by municipalities and urban planners who require comprehensive data to manage their stormwater and wastewater systems more effectively. StormSensor's overarching mission is to leverage data to build innovative and resilient communities, transforming how flooding and wastewater are managed to protect urban environments and reduce long-term costs.

StormSensor is a technology company founded in 2015 in Seattle that builds high-density IoT sensor networks and analytics platforms to provide real-time visibility into stormwater and sewer infrastructure. Its products serve municipalities, utilities, and urban planners by offering actionable data on flow, depth, temperature, and weather conditions to help manage urban flooding, reduce sewer overflows, and improve stormwater system maintenance and capital planning. The company addresses the critical problem of aging and unmetered stormwater infrastructure, enabling more efficient operations, emergency response, and climate change adaptation with affordable, scalable sensor networks and predictive analytics[1][3][4][5].
The company was founded by Erin Rothman, an environmental consultant with 12 years of experience, who teamed up with Anya Stettler to create a solution that automates stormwater monitoring and compliance reporting. The idea emerged from recognizing inefficiencies and high costs in traditional stormwater management. Early traction came from bootstrapping development and participation in the 9Mile Labs accelerator, leading to a working MVP and initial deployments. StormSensor’s vision is to create “Google Traffic Maps” for water infrastructure, making real-time sewer and stormwater data accessible and actionable for cities to build climate resilience[2][3][5].
StormSensor rides the growing trend of smart city infrastructure and climate resilience technology. As extreme weather events increase, cities face mounting pressure to modernize aging stormwater systems to prevent flooding, pollution, and costly repairs. StormSensor’s timing is critical, offering a data-driven approach to infrastructure management that leverages IoT, cloud computing, and AI to transform traditionally opaque and reactive systems into proactive, efficient networks. This aligns with broader market forces emphasizing sustainability, urban resilience, and digital transformation in public utilities[1][3][5].
Looking ahead, StormSensor is poised to expand its sensor network deployments and enhance its analytics capabilities, potentially integrating more advanced AI for predictive maintenance and climate risk modeling. As cities increasingly prioritize climate adaptation and infrastructure modernization, StormSensor’s influence is likely to grow, helping shape smarter, more resilient urban water systems. The company’s focus on affordability and accessibility positions it well to democratize critical infrastructure data, enabling broader adoption across diverse communities and accelerating the transition to sustainable stormwater management[3][5].
In sum, StormSensor is innovating at the intersection of IoT, environmental monitoring, and climate resilience, transforming how cities understand and manage their stormwater infrastructure in an era of increasing climate risk.
StormSensor has raised $12.6M across 3 funding rounds. Most recently, it raised $10.0M Series A in November 2021.
