A pioneering startup that emerged from the University of Cincinnati 1819 Innovation Hub's Venture Lab pre-accelerator program in 2018 was acquired by global solutions provider IDEX Corporation in 2024 for $7.5 million.
Subterra, founded by Robert Lee, revolutionizes sewer and pipeline infrastructure monitoring through its innovative watercraft, an AI-driven technology that aligns with IDEX's family of business solutions.
McKenzie expressed gratitude for a key local partnership with the Metropolitan Sewer District of Greater Cincinnati following a test pilot program. He credits the organization for recognizing the value of Lee's vision to protect workers and vital infrastructure. "Their progressive, forward-thinking approach allowed us to test and refine our technology with their input."
The need for regular infrastructure monitoring has never been more critical. Sewer systems across the United States, many of which are over 50 to 100 years old, are nearing the end of their lifespan. Climate change exacerbates the problem, leading to more frequent flooding and catastrophic failures, such as the Hyperion Treatment Plant spill in Los Angeles. The spill released millions of gallons of raw sewage into the Pacific Ocean, resulting in the deaths of marine life, contamination of beaches and residential areas, and millions of dollars in fines.
Unlike traditional inspection technologies, which are costly and infrequent, typically performed only once every decade or two, Subterra's FlowSIGHT solution enables cities to monitor pipelines regularly and affordably. By analyzing two or three data points over time, the system detects subtle changes, such as rising water levels, obstructions (like a stray basketball or an alligator in the sewer), or cracks that may lead to significant failures if left unaddressed.
"This technology is a game-changer for city infrastructure," says Lott. "Subterra's technology will help IDEX provide critical insights efficiently and cost-effectively to help cities and organizations take proactive measures to prevent environmental, social and economic disasters."
The UC Venture Lab pre-accelerator program, recently renamed UC's digital pre-accelerator program, continues to drive startup success by providing training, mentorship and resources to turn groundbreaking ideas into thriving businesses. Acquisitions such as this highlight the transformative potential of the UC Venture Lab and the Cincinnati Innovation District, which supports early-stage startups on their path from concept to commercialization.
Subterra's success story is a testament to the power of innovation, collaboration and the university's commitment to empowering the next generation of entrepreneurs who comprise the Center for the Silicon Heartland.
