STIMEY is a learning platform which combines current technologies, supported by pedagogical investigations, with the aim to familiarize the population between 10 and 18 years to STEM knowledge. With this paper we try to give some guidelines and tips for developing a project H2020 with guaranteed success. This project presented has a rating of excellent, maximum 15 points out of 15, which made us think it was possible to share this information so that other students can use. STEM, as readers will know, is an acronym of the words science, technology, engineering and mathematics, academic disciplines in which lots of university degrees are founded. They're the base in which humanity's scientific progress backs up, as well as subjects of wide acknowledgedment. The STIMEY project wants to approach this important knowledge to the young people in a friendly and fun way, with the intention of eradicating negative predisposition. It has the goal to remodel the teaching system, which is still tied to the past in many european countries, thereby increasing the interest in degrees related with STEM. This project is born with the intention of not only to change the vision of the students, but also to affect universities, high schools, teachers and even parents, making possible that all of them contribute to the improving of learning quality. With STIMEY, teachers will have more and better access to didactic resources, always verified and up to date. Parents will obtain a simpler way to watch their children trajectory, and education centers will be benefited with the increase of interest in STEM degrees
