Stephan Aarstol is the entrepreneur behind Tower Paddle Boards, the stand up paddle board company that landed a deal with Mark Cuban on Shark Tank in 2012. Since the TV appearance and Cuban's investment, Tower Paddle Boards’ annual revenues have grown more than 2500% -- that's in the last four years. Reporting $17 million in sales, Cuban has said Tower Paddle Boards is one of his best Shark Tank investments.
Tower Paddle Boards continues to grow by launching new products including Sunglasses By Tower, a line of handcrafted wood wayfarer sunglasses. Made with exotic hardwoods and polarized ultrasight lenses, the glasses come with a solid block carved sunglass case, and are on sale for $95 (originally $250). Other designs (Huntington, Trestles, Malibu, and San Miguels Wayfarers) are on sale for $59 (originally $120). Tower Paddle Boards will be featured on the Shark Tank spinoff, Beyond the Tank, which airs Thursdays at 8pm on ABC.The BEST SALES on Amazon NOW ]
