Why we exist
Modern fleets have more data than ever — ERPs, fleet management platforms, IoT telemetry, inspection checklists. But fire risk still sits in the cracks between them. An aging battery here, a deferred work order there, a pattern in the global incident database that no single operator would spot alone.
Traditional fire detection triggers at smoke. By then the vehicle is lost and passengers are already exposed. We start earlier, with the signals that are already there.
Who builds Underhood
Underhood is built by e6 Integrations, a Hungary-based engineering company that has been building embedded systems, telemetry pipelines, and integration platforms for industrial customers since 2019.
We are a mix of embedded systems engineers, public transit operations folks, and data platform builders. The founding observation was uncomfortably simple: the signals for most fleet fires exist weeks before ignition. They are just never looked at together.
Where we are headed
We start with transit buses, because they are the most fire-prone segment of public transport today and the data gap is the widest. Rail (engines, DMUs, EMUs) and marine fleets are next — the physics of modern propulsion failures is the same, and the signals travel the same pipelines.
Our ambition is a risk score per vehicle that is accurate enough to pull a unit from service before it burns. We are not there yet. We are close enough to ship the first pilots.
