EquipmentShare

EquipmentShare is a construction technology company founded in 2015 that builds cloud-connected platforms for one of the most physically dispersed and asset-heavy industries out there. Its proprietary T3 technology platform functions as a real-time operating system for jobsites, streaming billions of data points daily from over 349,000 connected assets across 385+ locations in 45 states. The attack surface is broad: fleet telemetry, workforce tracking, equipment control systems, and a sprawling IoT footprint feeding a cloud backend that contractors depend on for operational visibility. The threat model here is concrete. You're defending an IoT-heavy environment where connected assets - trackers, keypads, sensors - report back to cloud infrastructure at scale. The technical domains span data streaming, cloud-connected platforms, equipment tracking, and jobsite technology. If the data pipeline goes down or gets compromised, real-time fleet visibility disappears across thousands of active construction sites. The company grew from a Y Combinator seed project building equipment trackers into the fourth-largest equipment rental operation in the US, which means the platform scaled fast and the security challenges scaled with it. EquipmentShare's integrated model - rental, retail, service, and parts all running through the T3 platform - creates a complex data environment where IT, OT, and physical access converge. Security roles here aren't abstract policy work; they're embedded in a system where billions of daily telemetry events, user authentication across field workers and back-office systems, and API integrations with construction workflows all need to stay locked down without slowing down a fast-moving operation that earned recognition on both the Inc. 5000 and Forbes' list of America's Best Startup Employers.
