The gambler CNBC has agreed to call "Justin" first came across Sports Insights when the company ran a promotional offer to test their services. For $250 a month, members gain access to data from multiple offshore sportsbooks showing exactly how the public is betting, and where so-called "sharp" or professional gamblers are putting their money.
Additionally, the company highlights its daily "best bets" — propositions that have historically proved profitable, hitting at a 55 percent win rate since 2005.
"Our two foundational philosophies when it comes to sports betting are: Bet against the public and follow the sharp action," Sports Insights manager Josh Appelbaum explains. "The reason we bet against the public is because more often than not, the public loses."
A bias towards betting home teams, favorites, and what's known as "the over" tends to open up opportunities for professional gamblers. When they act, the company alerts its users, so that they can act too.
