The massive technology conference Techweek references past attendees and sponsors to illustrate how popular and illustrious the event is. If you don’t have big names to reference you can include testimonials and reviews from past attendees to create the same effect. One study showed that 79% of customers trust online reviews as much as personal recommendations.

“Techweek curates exciting programming that allows a global spotlight to shine on each ecosystem and its leaders. Past speakers include Rahm Emanuel, Travis Kalanick (CEO, Uber), Craig Newmark (Founder, Craigslist), Barney Harford (CEO, Orbitz), and Chuck Templeton (Founder, OpenTable). The Techweek expo has gathered more than 200 sponsors, including companies such as Google, Groupon, Microsoft, Motorola, Redbox, Uber, and WordPress.”
