One of the main goals of the ‘Yes We Tech’ community is contributing to create an inclusive space where we can celebrate diversity, provide visibility to women-in-tech, and ensure that everybody has an equal chance to learn, share and enjoy technology related disciplines. As co-organisers of the JOTB event we are happy to see that the number of women speakers has been doubled this year from 5 to 10, representing a 20,8% of the total. But, Is this diversity enough? How can we know that we have succeeded in our goal? and more importantly, how can we get a more diverse event in future editions? In this meetup we have used big and small data to know more about J, explore the community, and to analyse the topics, people, and activities which can influence to create a more diverse conference.
