Hi, I am Martijn. I am a strategy consultant specialised in innovation and marketing. I am partner in a consulting company based in Amsterdam called Fronteer Strategy, and we work on interesting strategic projects for market leaders in consumer goods, technology and communications, FMCG and financial services. We find market opportunities, create concepts and help clients bringing them to market. We have been doing co-creation for a long time, which culminated in a product called Rooftop: innovate with experts. We put our clients in the same room as professionals who know their stuff and tackle clients' strategic challenges together. We are always looking for people to join our Rooftop network. See www.welcometorooftop.com for more on this. People in the network benefit through working on exciting projects (paid of course..) and meeting other Rooftop people. Workshops are held globally.
