CivilGrid Raises $26M Series A to Build a "Google Maps for the Underground"

CivilGrid, an underground infrastructure data platform, raised $26 million in Series A funding led by Spark Capital, announced August 27, 2026. Afore, A*, and Energy Impact Partners participated alongside early-stage investors Ford Street Ventures and SNR. The company is led by CEO Josh Mackanic, a former PG&E engineer, and counts PG&E among its current customers.

What CivilGrid Builds

CivilGrid provides a civil design platform that consolidates fragmented site datasets, including subsurface assets, municipal projects, environmental regulations, and land ownership, into a single collaborative map, aiming to address chronic inefficiencies in construction planning caused by underground infrastructure data being scattered across incompatible municipal, utility, and private records. The company currently sells platform access to government agencies, civil engineering firms, and utility companies, positioning itself at the intersection of infrastructure software and the physical build-out that supports power, water, telecom, and transportation networks.

Why the Category Matters Now

Mackanic's background as a PG&E engineer is directly relevant to the problem CivilGrid is solving: utilities and civil engineers routinely plan and execute projects without reliable, unified visibility into what already exists underground, a gap that has contributed to costly delays, accidental utility strikes, and duplicated survey work across the industry. As US infrastructure spending accelerates across grid modernization, broadband buildout, and water systems, the cost of poor underground data visibility compounds, making a platform that can consolidate this data into one usable map increasingly valuable to both public agencies and private contractors. The funding will accelerate CivilGrid's national expansion and deepen its product capabilities, and PG&E's presence as a customer gives the company a credible reference within the utility sector it is targeting for wider adoption.

What This Means for Founders

CivilGrid's raise is a useful example of a founder building a data and software layer on top of deep domain expertise gained from working inside the exact industry the company now sells into. Founders building infrastructure software, govtech, or other categories where incumbent data is fragmented across public and private sources can use the investor match tool to identify investors with genuine infrastructure and climate-tech portfolio experience rather than generalist enterprise software interest. Founders selling into government agencies and utilities in particular should be prepared to discuss long sales cycles and their own runway assumptions clearly, since public-sector and utility contracts often close more slowly than typical enterprise SaaS deals even when the underlying value proposition is strong.
