Call for Papers

Speaking at a conference will improve your personal brand and open job opportunities. Moreover, it will make you come out of your comfort zone, push you towards mastering a topic and most importantly it gives back to the community.

Speaker benefits:

  • Wednesday Speaker dinner invite.
  • Speakers will receive admission to the conference.
  • Upon admission, travel and accommodation in the conference hotel will be covered by the conference for those coming from outside Madrid area. If your company pays your travel and expenses, it increases your chances of being accepted. We run the conference in a low budget and because of that we have a limited number of slots for speakers with travel and expenses needs.
