About Plotwise

Plotwise developed cloud-based software for last-mile delivery planning, combining mathematical optimization, artificial intelligence and predictive traffic modeling. Its platform helped retailers and logistics providers coordinate deliveries as orders arrived, connecting route planning with the delivery choices offered to customers during online checkout.

Founded in 2011 as Calendar42, the business originated as a technology spin-off from Delft University of Technology. Its early work focused on algorithmic scheduling for individual mobility and healthcare transport. It subsequently shifted toward e-commerce logistics and adopted the Plotwise name, addressing the planning challenges created by growing parcel volumes and demand for convenient delivery windows.

Planning during checkout

The Plotwise Planning API calculated delivery propositions within milliseconds. Rather than relying on routes prepared overnight, it brought planning into the shopping process, allowing delivery windows and routes to respond to incoming orders and changing conditions. Its calculations considered traffic congestion, parcel dimensions, nearby scheduled deliveries and vehicle capabilities.

The platform supported order pooling and mixed delivery fleets, including electric vans and cargo bicycles. This connected customer-facing delivery promises with practical distribution constraints, helping operators coordinate available capacity and reduce unnecessary travel. Its commercial focus included e-commerce retail, parcel distribution, postal networks and transport logistics, particularly in the Netherlands, Belgium and Germany.

Integration into Coolblue

Coolblue used Plotwise as a software supplier before acquiring the company on April 11, 2022. The acquisition supported the retailer’s efforts to improve delivery planning and optimize its logistics operations, including its CoolblueBikes fleet.

On December 31, 2022, Plotwise was legally merged into Coolblue B.V. Its engineering personnel and software assets became part of Coolblue’s logistics technology department, ending its independent operation. The Plotwise website, company profile and published contact address are historical references to the former business.

More about Plotwise

Founders

Michel Boerrigter founded the venture. The report also identifies Jasper Hartong and Arnoud Rozendaal as co-founders who joined its historical leadership team and helped execute the pivot toward delivery planning. These are historical roles, not current executive appointments.

Investment

Backers included Delft Enterprises, the Mainport Innovation Fund and ENERGIIQ. ENERGIIQ, the energy innovation fund of the Province of South Holland, invested €1.1 million in late 2020.

Reported operational impact

The supplied research reports that the technology enabled logistics operators to reduce driven distances and vehicle requirements by upwards of 20%. This is a reported platform outcome rather than a guarantee for every deployment.
