The full attendee list is available on the mobile app.
When you open your mobile app and go to 'Discovery', you'll be able to search for People, Partners, Startups and Sessions. You will also find the filter button - this tool will allow you to filter attendees by Role, Industry and Location.
Once you've made connections through the Web Summit Rio mobile app, you will be able to download all your connections into a single document. This will include the name, company and contact of the attendees you have connected with.
