Working for the lab., as part of the Roadsafetylab Holding, provides insight into driving behavior. Our service is based on existing telematics, OEM or mobile data. gribb places enriched data in the right context and makes it actionable. gribb combines people, technology, data, road safety marketing and micro-learning to achieve our goal: 0-work-related traffic accidents as a result of human errors.

We see technology and systems that take over driving tasks from drivers as a huge opportunity. We use that technology, our data and roadsafety marketing to influence traffic behavior from automaticity to conscious behaviour. With our data we predict and ultimately prevent traffic accidents in work traffic and we are getting closer every day to our ultimate dream: a world without work traffic.

"A goal without a plan is just a wish". Together with our customers, employees and our shareholder, we are working hard on the solution to prevent damage and accidents in traffic. We work with the biggest names who, like us, have the ambition to make an impact and therefore reach out to us to achieve our goals. Road safety is a business case.
