Sébastien Willems is the Founder & CEO of Antfarm, where he’s building autonomous robots that sort our waste. Before Antfarm, he co-founded Presspage, a PR SaaS platform that grew into a global player serving Fortune 500 companies, and ultimately sold it to Banyan Software in 2025. Driven by a passion for both technology and sustainability, Seb shifted his focus to one of the world’s most pressing problems: waste. At Antfarm, he and his team of engineers are developing autonomous sorting robots that make material recovery 10x more efficient. By combining advanced robotics with AI, Antfarm is working to transform how the world deals with waste—turning what’s thrown away into valuable resources.
