Forerunner is an AI-powered intelligence layer that helps local governments connect fragmented systems and geospatial data to operate with clarity and precision. Cities and counties invest heavily in permitting systems, asset management tools, and GIS, yet critical work still falls through the cracks because those systems don’t reflect what’s happening on the ground. Field observations go uncaptured, data is siloed, and teams struggle to turn information into coordinated action. Forerunner works alongside the systems agencies already use, unifying data and guiding frontline teams through an AI-powered, mobile-first experience. By connecting real-world conditions to back-office workflows, we ensure the right work gets done with the right context—whether it’s inspections, code enforcement, storm response, or long-term resilience planning. The result is faster, more consistent execution that reduces risk, surfaces revenue, and prevents small issues from becoming costly emergencies. Today, we partner with nearly 200 communities across the country and recently raised a $26M+ Series B to accelerate our growth—expanding our platform and team to support the agencies building stronger, safer communities.
