Summary
👤
Senior🎓
Top SchoolJan-willem Janssen is a seasoned freelance researcher and consultant with 15 years’ experience specializing in retail technology, internet retailing and innovation. He combines rigorous research methods with hands-on business development to evaluate new business models, consumer behaviour and web analytics for retailers and financial services. Jan-willem has a long track record—spanning roles from research manager to founder and content manager—helping local stores compete with online platforms by designing effective local distribution and non-linear retail strategies. He focuses on practical, bite-sized engagements now (desk research, surveys, interviews, and policy notes) rather than full project leadership, reflecting a preference for focused impact over managerial responsibility. Based in 's-Hertogenbosch, he brings a pragmatic mix of statistical rigor and sectoral insight, and an often-overlooked strength: deep experience translating technical payment and POS topics into impartial guidance for frontline merchants.
