SewerAI, an AI platform for sewer and underground infrastructure intelligence, announced a major strategic investment led by JMI Equity, with continued participation from Innovius Capital, Epic Ventures, and Bentley Systems.
The investment will support SewerAI’s mission of helping utilities, engineers, and contractors inspect, assess, and rehabilitate aging underground infrastructure through AI-powered technology. The announcement comes as municipalities across the United States face growing challenges related to deteriorating water and sewer systems, increasing regulatory demands, labor shortages, and rising infrastructure costs.
Founded in Walnut Creek, California, SewerAI combines artificial intelligence, cloud technology, and infrastructure expertise to help organizations transform raw inspection data into actionable decisions, rehabilitation plans, and long-term asset management strategies. The company’s platform currently supports data from more than 2,000 cities, manages over 30,000 miles of pipe, and has completed more than 850,000 NASSCO surveys through its AutoCode™ AI engine.
SewerAI’s customer base includes major municipalities such as City of Houston, City of Phoenix, and KC Water, as well as engineering and infrastructure organizations including HDR and PURIS.
The company has experienced significant growth since its founding, including tripling its customer base over the last two years, processing millions of feet of underground infrastructure data each month through AI-powered workflows, launching new planning and decision-support capabilities such as Smart Project Builder and Risk & Rehab for manholes, and building what it describes as the industry’s largest infrastructure inspection dataset.
Looking ahead, SewerAI plans to expand the use of AI beyond inspection into rehabilitation planning and program management. Key priorities include enhancing AutoCode™ performance, expanding Risk & Rehab™ capabilities for capital project prioritization, deepening integrations with platforms such as Esri ArcGIS, Trimble, and OpenGov, and developing additional workflows to help utilities meet regulatory and consent-decree requirements more efficiently.
According to the company, its platform differentiates itself from traditional infrastructure software by providing an integrated system that helps organizations capture, analyze, collaborate around, and act on infrastructure data. The platform includes AI-powered condition assessment, quality assurance, risk scoring, rehabilitation planning, digital submittals, and project development capabilities.
The transaction was advised by Shea & Company, which served as SewerAI’s exclusive financial advisor.
KEY QUOTES:
“Today, we’re not just announcing a fundraise. We’re declaring that the era of neglected infrastructure is over. JMI is one of the most disciplined growth investors in the world, and their investment in SewerAI is a vote of confidence for an entire ecosystem: the cities maintaining the systems beneath our feet, the engineers designing what comes next, the operators in the field every day, and the builders who still believe American infrastructure can be the best in the world. We are incredibly excited for the future.
We’ve always believed infrastructure professionals deserve technology that helps them work faster, make better decisions, and reduce risk and the total cost of infrastructure. Our partnership with JMI allows us to continue investing aggressively in the products and people helping our customers become superhuman.”
Billy Gilmartin, Co-Founder and Co-CEO, SewerAI; Matt Rosenthal, Co-Founder and Co-CEO, SewerAI
“SewerAI sits at the intersection of several powerful tailwinds: aging pipeline infrastructure, labor constraints, and the rapid adoption of AI-powered automation. The company has demonstrated exceptional product-market fit, a rapidly expanding customer base, and a clear vision for transforming how critical infrastructure is managed. We are excited to partner with the SewerAI team as they continue building the category-defining platform for underground infrastructure management.”
Chase Thomet, Partner, JMI Equity
“At the City of Phoenix, we manage one of the nation’s largest sewer collection programs, and we’re expected to do more with the same resources each year. SewerAI helps us inspect, prioritize, and report at a scale that wasn’t possible before. Just as importantly, it puts our data in one place, making it easier to thoroughly explain inspections and make projections for future capital improvements.”
Patrick R. Womack II, SDSSR Program Manager, City of Phoenix Water Services Department
