Major Strategic Investment Supports SewerAI’s Mission

By Trenchless Technology Staff June 4, 2026

Walnut Creek, California-based SewerAI announces a major strategic investment led by JMI Equity, a leading growth equity software investor. Existing particpation from Innovius Capital, Epic Ventures and Bentley Systems remains in place.

The company’s platform combines artificial intelligence, cloud technology, and infrastructure expertise to help organizations move from raw inspection data to decisions, rehabilitation plans, and long-term asset strategies faster than ever before. Today, SewerAI’s end-to-end AI platform supports data from more than 2,000 cities, manages over 30,000 miles of pipe, and has completed more than 850,000 NASSCO surveys with its AutoCode AI engine.

Customers include the City of Houston, the nation’s largest sewer collection utility, which leverages SewerAI to manage its EPA Consent Decree obligations, the City of Phoenix, and KC Water. The platform also supports thriving engineering firms and contractors including HDR and PURIS, alongside a broad network of municipal utilities, engineering firms, and CCTV inspection contractors across North America.

“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,” says Matt Rosenthal, co-founder and co-CEO of SewerAI. “Our partnership with JMI allows us to continue investing aggressively in the products and people helping our customers become superhuman.”

Since its founding, SewerAI has experienced significant momentum, including:

Tripling its customer base over the last two years
Processing millions of feet of underground infrastructure data through SewerAI’s AI-powered workflows every month
Launching new AI-powered planning and decision support capabilities including Smart Project Builder and Risk & Rehab for manholes
Building the industry’s largest infrastructure inspection dataset

“Today, we’re not just announcing a fundraise. We’re declaring that the era of neglected infrastructure is over,” says Billy Gilmartin, co-founder and co-CEO of SewerAI. “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.”

SewerAI’s near-term roadmap focuses on extending AI from inspection into rehabilitation planning and program management. Priorities include continued accuracy and throughput gains in AutoCode, expanded Risk & Rehab capabilities for prioritizing capital projects, deeper integrations with partner systems including Esri ArcGIS, Trimble, and OpenGov, and new workflows that help utilities meet regulatory and consent-decree obligations on faster timelines and at lower cost.

“SewerAI sits at the intersection of several powerful tailwinds: aging pipeline infrastructure, labor constraints, and the rapid adoption of AI-powered automation,” says Chase Thomet, partner at JMI Equity. “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.”

Unlike traditional infrastructure software that focuses solely on inspection storage or isolated workflows, SewerAI provides a connected platform designed to help organizations capture, analyze, collaborate around, and act on infrastructure data. The company’s suite includes AI-powered condition assessment, quality assurance, risk scoring, rehabilitation planning, digital submittals, and project development capabilities.

Shea & Company, LLC served as exclusive financial advisor to SewerAI on the transaction. The software-focused investment bank has the industry’s leading critical infrastructure, government technology and construction technology practices, with prior advisory work for companies including First Due, Granicus and OpenGov.
