OleOle OleOle is building a social network and messaging platform for football/soccer. In-match gambling driven by live score updates is the driver of our model. What we do... oleolesport.com empowers people to identify footballexperience and without any search requirements, simply presents the traveler with vetted components necessary to bring the trip to life -- tickets, lodging, flights and beyond. And we are building a football super app. Why it matters... Searching and successfully planning a trip around an iconic football experience is time-consuming, frustrating, overwhelming and often times elusive. Football is complicated unlike any other sport with players playing for club and country simultaneously. Fans are looking for a place to "Kick Off". Why we are better... oleolesport.com’s searchless travel approach means a soccer/footballexperience can be discovered, planned and purchased in a matter of minutes without the endless search-driven lunacy and inefficiency that comes with all travel planning. There isn’t a sports social network, although some claim to be, however they lack even the slightest understanding of network platforms.
