In 2017 just 2 years from launch, Europe’s biggest logistics company GeoPost (Groupe La Poste) acquired Stuart so that it could join prestigious companies like DPD, Colissimo, SEUR & Chronopost and conquer urban logistics.

With an exciting blend of GeoPost Group expertise and a fun, agile start up culture; Stuart has expanded to more than 30 cities across the UK, France & Spain and continued the steep growth curve it’s become accustomed to.

We’re passionate about looking at problems in fresh and innovative ways – every problem is just opportunity for a great solution. We love to invent new ways of doing things and come to work every day with smiles on our faces.
