What it does: runs a mobile-based events ticket marketplace. D’souza and groetzinger quit management-consulting jobs in 2008, and hit on the idea of aggregating tickets to sports, concerts, broadway shows and more that were selling in over 100 secondary marketplaces like stubhub. last year, seatgeek moved into primary ticketing, hoping to disrupt an area dominated by ticketmaster. its new seatgeek open platform allows performers and teams to sell tickets directly through apps and websites that fans already use.
