About

Hi, I'm Koen Knol, the founder of Comment Picker. I’m based in the Netherlands and I build web tools that help brands, creators, and agencies run giveaways more efficiently and fairly.

I'm a frontend developer with a passion for building products from idea to launch. My main interests are social media, AI, SEO, and online marketing.

My goal is simple: make Comment Picker the most reliable and user-friendly platform for giveaways and social media tools, so brands and influencers can grow their online presence with confidence.

Other projects

I'm also building RekenBuddy, a Dutch platform with reliable, user-friendly calculators for topics like work & income, mortgages & housing, taxes, benefits, savings, loans, investing, entrepreneurship, pensions, and AOW.
