Hi! I'm an author, marketer, and data enthusiast with a passion for storytelling and making books irresistible to readers. Under my pen name, I. C. Cosmos, I've published six bestselling thrillers and a guide on self-publishing.

Before diving into full-time writing and publishing, I advised global brands like AT&T, KPMG, Twynstra Gudde, and Heineken. My work combined data analytics with psychological insights—crunching numbers, fine-tuning marketing strategies, optimizing user experiences, and building strong, resilient teams.

My career took an intriguing turn when I became director of EFP, a Dutch forensic psychiatry knowledge center. It was a high-stakes, high-stress job—but also a masterclass in applied analytics and human behavior. There, I discovered fascinating parallels between predicting criminal behavior and marketing products: both rely on analyzing demographics, psychographics, and behavioral patterns—skills directly transferable to book marketing.

Today, alongside writing, my main focus is helping fellow authors self-publish their books and refine their advertising campaigns. Whether it's targeting the right audience, testing Facebook ads, or decoding Amazon’s mysterious algorithms, I love the challenge of pairing great content with the right readers.

If you have any questions, suggestions, or recommendations

I'd love to hear from you ☺️
