Maarten Engelen is a venture capital investor at DFF Ventures who co-founded companies in vastly different sectors—Treatwell (a beauty booking marketplace) and Hiber (a satellite IoT company)—before becoming an investor, giving him an unusual mix of consumer and deep-tech operating experience. He focuses on backing insider founders who are digitizing analog B2B industries through complex infrastructure plays, approaching investments with a technical mindset that evaluates distribution speed over prototyping ease and seeks products that can become critical industry rails.
