Simplify's Take

What believers are saying

  • Houston approved a $5.73 million, five-year contract in April 2026.
  • Smart Project Builder launched February 2026, turning inspections into budget-ready rehab plans.
  • July 2026 PIONEER training introduced Command Center, expanding workflow automation.

What critics are saying

  • Houston's contract concentration exposes SewerAI if the city delays renewals after 2028.
  • Trimble Cityworks and Esri can bundle competing workflows into existing procurement relationships.
  • If AutoCode miscodes defects in consent-decree work, utilities will reject the platform.

What makes SewerAI unique

  • SewerAI's PIONEER unifies CCTV ingestion, AI coding, risk scoring, and rehab planning.
  • June 2026 JMI Equity backing validates category leadership and funds expansion.
  • AutoCode processes 850,000-plus NASSCO surveys across 2,000 cities, creating a rare data moat.

SewerAI secures major strategic investment to accelerate the future of underground infrastructure management.

SewerAI secures major strategic investment to accelerate the future of underground infrastructure management. * 4 hrs ago SewerAI, the leading AI platform for sewer and underground infrastructure intelligence, today announced a major strategic investment led by JMI Equity, a leading growth equity software investor based in the greater DC area and San Diego, with continued participation from Innovius Capital, Epic Ventures, and Bentley Systems - seasoned investors known for backing category-defining technology companies. This investment comes as the National League of Cities' 2026 Municipal Infrastructure Conditions Report finds water and sewer infrastructure facing the steepest declines in condition of any major asset category since 2022, even as cities continue to rank them among their highest capital priorities. Closing that gap requires faster, more accurate ways to inspect, assess, and prioritize the systems beneath every city - work that has historically been slow, manual, expensive, and prone to error. 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(TM) 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. "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," said Billy Gilmartin, Co-Founder and Co-CEO of SewerAI. "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," said 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 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(TM), expanded Risk & Rehab(TM) 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," said 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. "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," said Patrick R. Womack II, SDSSR Program Manager at the City of Phoenix Water Services Department. "SewerAI helps Mycarrollcountynews inspect, prioritize, and report at a scale that wasn't possible before. Just as importantly, it puts its data in one place, making it easier to thoroughly explain inspections and make projections for future capital improvements. 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.

The company's PIONEER(TM) platform unifies field capture, cloud-based data management, AI-assisted NASSCO coding through AutoCode(TM), and AI-driven capital planning through Risk & Rehab(TM), connecting every step from the field to the master plan.
