Logistics for a sustainable world.” That is the mission at the heart of Stuart Delivery. While customer expectations around the delivery experience are skyrocketing, cities are limiting traditional logistics methods to improve congestion, pollution and liveability. The convergence of these two trends means that a disruptive approach to last mile delivery is not a nice-to-have but rather an inevitability.

Stuart sits at the crossroads of the future, using our best-in-class proprietary dispatch technology to connect small and big businesses alike to a shared fleet of geolocalised couriers. The result? Efficient, reliable, eco-friendly delivery to help retailers to meet their customers’ demands.

We launched in 2015 with a big vision and a handful of clients. 5 years later couriers on our platform complete tens of millions of deliveries annually for the biggest brands across retail, ecommerce, grocery and food.

Stuart is an equal opportunity employer and we value diversity at our company. We don't discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status or disability status.
