I love to work with organizations on conversion optimization projects. Securing optimization and experimentation in the DNA of teams and organizations gets me up in the morning. It's an extensive range of work that I like: from the broad strategic perspective on the one hand to the nitty-gritty details of user growth opportunities within digital channels on the other hand. Ultimately, it's all about solving problems, which I do fast and effectively based on data.Examples of projects I've finished successfully in the past:✓ E-commerce company (NL): leading the check-out funnel conversion optimization project.✓ Publisher (EU): training product teams on experimentation and persuasion tactics.✓ Banking (NL): training the marketing teams to become more effective in CRO.✓ Travel company (NL): leading the organization's project to set up CRO.✓ Telecom company (EU): consulting on CRO projects at several offices.Reach out if you want me to help you set-up or improve the effect of Experimentation in your Organization.

Occasionally I host Conversion Optimization and A/B-testing masterclasses and workshops, mostly co-organized with Conversion Optimization related industry events.I'm also available for in-house training: live and remote.
