CivilGrid Raises $26M Series A to Map What's Underground
CivilGrid, a startup that combines data on buried utility lines, property ownership, and environmental rules into a single platform, has closed a $26 million Series A led by Spark Capital. The round, reported on August 27, 2026, included participation from Afore, A*, Ford Street Ventures, SNR, and Energy Impact Partners, a fund whose LPs include utility companies TechCrunch.
Founder Josh Mackanic spent ten years as an engineer at Pacific Gas and Electric before launching CivilGrid in 2020. The founding problem is concrete: during a PG&E excavation job, an unknown buried pipe forced a shutdown that cost $60,000 over three days. CivilGrid describes itself as a "Google Maps for what's underground," selling access to governments, civil engineering firms, and utilities, including PG&E itself.
The scope of the problem is large. Approximately 200,000 utility strikes occur annually in the United States because crews cannot see what is buried below the surface before they dig. A PG&E case study conducted using CivilGrid identified $60 million in avoidable paving costs across 1,600 planned gas distribution projects.
CivilGrid is not the only company pursuing subsurface mapping. 4M Analytics, an Israeli firm, raised an $11 million round led by Viola Ventures in August 2021, then extended its Series A by $30 million in September 2022, bringing total Series A funding to $45 million with the stated goal of becoming "the Google Maps of the subsurface" (PR Newswire, Calcalist Tech). Exodigo closed a $105 million Series A in February 2024 to lead the underground mapping sector (Informed Infrastructure).
The "Google Maps for X" framing extends well beyond subsurface data. Felt, a collaborative mapping platform, raised a $15 million Series A led by Footwork in May 2022 (TechCrunch). Drivetrain, which calls itself "Google Maps for business growth," raised $15 million from Elevation Capital and Jungle Ventures in October 2022 (TechCrunch). And OpenStreetMap, the crowdsourced mapping platform that turned 20 in August 2024, has been the enduring reference point for open geospatial data since its launch on August 9, 2004 (TechCrunch).
The broader context here is that subsurface infrastructure mapping sits at the intersection of several durable trends: aging utility networks, regulatory pressure around excavation safety, and the maturation of geospatial data infrastructure. The 200,000 annual utility strikes figure suggests a market failure that software can plausibly address, and the PG&E case study's $60 million paving-cost finding indicates that the value proposition extends beyond strike avoidance into project planning efficiency. CivilGrid's inclusion of Energy Impact Partners in the round is consistent with the idea that utilities are both the source of the problem and the likely beneficiaries of a solution.
What distinguishes CivilGrid from competitors like 4M Analytics and Exodigo is less clear from available facts. All three target the same subsurface mapping problem space, and all have raised meaningful capital. CivilGrid's go-to-market focus on governments, civil engineering firms, and utilities, rather than on a sensing or surveying technology stack, suggests a data-aggregation and platform approach rather than a hardware-centric one. Whether that positions CivilGrid as complementary to sensor-based competitors or directly competitive is an open question.
The participation of PG&E as both Mackanic's former employer and a current customer closes a loop that is worth noting. The utility that experienced the $60,000 delay caused by an unknown pipe is now using the platform built in response to that incident, and has identified $60 million in avoidable costs through a case study with the same tool. Whether that figure translates into sustained operational savings at scale is not yet clear, but the internal validation from a major utility is a meaningful data point for a company at this stage.
