I co-founded Actuable, we built an MVP in a weekend which got 10.000 users in 3 weeks and 1M users in 10 months. Acquired by @Change.org. I founded @Mumumio, an artisan food marketplace where I led product and marketing. We had a yearly revenue of 0,5M€ with hardly any marketing budget. I worked at The Cocktail, a leading user experience consultancy in Spain, where I worked for big companies, and where I led the creation of several departments (front-end, development, online marketing). We introduced Ruby On Rails in Spain, building the biggest site at the time. I do some angel investment in which I also contribute UX+marketing advice.Describe the most impressive thing you've done.
