## About

Based in California, US, and founded in 2019 by co-founders Matt Rosenthal (CEO) and Billy Gilmartin (CRO), SewerAI Corporation operates as a provider of AI-powered inspection platforms, offering sewer condition assessments to engineering firms and public works departments. In June 2026, SewerAI Corporation raised an undisclosed amount of series B funding led by JMI Equity, with participation from Bentley iTwin Ventures, EPIC Ventures, and Innovius Capital. The company will use the funding to expand its platform capabilities, improve inspection and planning features, and support development of tools for managing underground infrastructure.

The company provides an AI-based platform that offers digital tools to utilities and municipalities. The platform's services include AutoCode, which automates defect identification in CCTV footage, and Pioneer, a sewer management tool. Moreover, the firm offers solutions such as GIS mapping, cross-bore safety audits, and 360-degree video inspections. Additionally, the company also provides services such as custom video overlays, pipe data analytics, and digital submittals.
