Executive Summary
Eric van Dijk is the founder and Chief Executive Officer of Slimstock, a supply chain planning software company based in Deventer in the Netherlands. He started the business in 1993 around a narrow but persistent problem for distributors, retailers and manufacturers: how much stock to hold, and when to reorder. Its Slim4 platform now covers demand planning, inventory optimisation and replenishment, and the company reports offices in 28 countries and more than 1,700 customers. More than three decades on, he still leads it.

Professional Journey
Van Dijk founded Slimstock in 1993 in Deventer. The company specialised from the start in forecasting and inventory optimisation, and its core product, Slim4, grew into an end-to-end planning platform covering demand planning, inventory optimisation, portfolio management and replenishment.
Under his leadership Slimstock expanded well beyond the Netherlands. In October 2024 it opened an office in Casablanca, with van Dijk describing Morocco as “a vital gateway for both local and international businesses — a strategic hub connecting to Africa.” Slimstock now reports offices in 28 countries, activity in 75, and more than 1,700 customer organisations, and in 2026 it announced offices in Mexico alongside partnerships with ERP ecosystems including SAP and Sage.
In a 2019 interview he framed his job as making clear to everyone what keeps the company relevant, and described exposing recent graduates to warehouse and manufacturing operations as a way of testing his own thinking. In November 2025 Slimstock won the Deventer Entrepreneur Award, which van Dijk accepted as CEO, remarking that crossing the River IJssel back into Deventer “always feels like coming home.”
