 Thank you, Jaime. Hi everyone and welcome from your houses. This is the ninth edition of Big Things. This is an event to talk about technology, innovation, but this year edition we want to focus the event in technology for good. What is technology for good? Any decision we take has an impact. So we want to inspire the people, the companies to use technology for good to improve society, to improve world. This is the reason we want to share a video in which we want or we have tried to explain how technology for good will generate a positive impact, but technology not for good will generate a negative impact. So please play video. And from everywhere we would love to welcome you at Kinepolis one more year, but we have to adapt to current circumstances. This is why we are here bringing you this Big Things home edition. Looking into the bright side, thanks to the format of this event, we are able to welcome attendees from completely different places in the world. In fact, 20% of our attendees are international. In order to accommodate you all, we have been working with more than 10 time zones. This is why we have organized a schedule or work agenda in the afternoon continental time. We are privileged to have speakers from every corner of the world. We bring you the best of the best, like Grady Butch or Afsar asking who are in no other place than Hawaii. Big Things was born in 2012 to share technology and innovation in Spain. Now it's an international event and we are opening the new edition, continue growing with big numbers. During these eight years we have been able to learn from more than 500 speakers. We have been able to create a community with more than 10,000 members and to have the support with more than 60 companies and we continue growing. All of this has made Big Things one of the largest and most prestigious non-profit conferences in Europe. In this new edition, we will continue doing what we do best. During three days with three simultaneous tracks and 62 international speakers, we will talk about technology, innovation and we will try to inspire you and most importantly we will help to develop connections and relationships between companies, audience and speakers. Jaime will show us later how to hold this networking platform in the conference site works. This year we won't have physical stands but instead we recommend you to visit the virtual stands in the conference site where you will see what our sponsors are working on and like every year we will have games and prizes and we will explain you later how to participate. So like in our previous edition we will have several tracks because this is the home edition we will have the inspirational track in the launch then we will have the business in the attic and the technology in the garage. So we will include talks that are good or designed for technical people for business people and also we will have talks about COVID the COVID crisis like Nuri Oliver talking about data to strike down COVID-19 and also José Luis Florez about digital epidemics and apps because as everybody knows there are useful apps and not so useful apps. Also we will talk about business successes with Manuela Veloso from GP Morgan talking about human-AI interaction, examples in AI and finances and also we will have success use cases from big and great companies like Elcorte Inglés, Thepsa, Repsol, Telefonica and BBBA. In the launch we will have really inspirational speakers it's a luxury to have Grady Butch who in his keynote will talk about the story of computing and we are also lucky having Azar asking who will reflect about our social dilemma and how to protect humans and societies. You shouldn't miss our amazing closure talk by Stefan Wolfram who will talk creator of Mathematica who will talk about computational language and artifacts from the future. We will have two really interesting roundtables moderated by our master of ceremony Jaime García. So in the attic we will have the business-oriented talks Elena Diaz Fuentes will introduce speakers like Yes Anderson director of big data institute that will talk about foundations of data teams or speakers like Nick Pentrid or Maria Medina a young and successful woman who is leading great projects in Microsoft. And our more technical talks will take place in the garage. Nicolás Randall will be in charge of welcoming in this room really relevant speakers like Tony Prada from Cavify, Germán Viscuzzo from Amazon, Julián Molotcia from MSD, K-Wena from Confluence, Arvin Josajagara from Madwards and Philip Cren from Elastic. And finally we would like to thank our sponsors this event will not be possible without the sponsors and it is also really comforting to see how companies and people are helping during this COVID crisis supporting technology and trying to inspire people to use technology for good. So we want also to say goodbye reminding that this event is a neutral event non-profit and that all the speakers participate without any interest. So please thank all the speakers when they are talking when they are sharing because they are making a big effort to share what they are doing worldwide. So the philosophy of big things is share, enjoy and remember technology for good. So now Jaime will explain how to use the platform, the gamification, the networking, so Jaime back to you.
