Our take
Zeelo provides a personalised shared mobility service for underserved areas using data analytics. The AI-powered algorithm allows the company to design routes that meet the needs of customers, so they can make the most of their travelling time.
The Zeelo platform integrates with an executive vehicle fleet of over 20,000 high quality coaches across the UK in order to serve demand. And as the number one shuttle provider across the US, Uk, and Ireland, Zeelo now transports hundreds of thousands of passengers every month.
With the shifting attitudes towards sustainability, Zeelo now provides services that use less energy and are more sustainable, which will appeal to the environmentally conscious. The challenge will be growing its niche, with stiff competition in everyday ride sharing from Uber and others. But with recent funding, the company looks ready to accelerate its growth across the US and make an even bigger name for itself.
