The growing popularity of endurance sports means major revenue growth for Ponte Vedra Beach-based sports apparel maker 110%. The 4-year-old company makes compression socks and other apparel that help professional athletes and recreational runners recover from injury. Revenue doubled in the last year, says CEO David Green. The company has grown from selling in 89 specialty running stores in 2011 to nearly 250 last year. 110% was founded in 2008 after a group of investors purchased the intellectual property rights to the compression technology. Harbor View Advisors, a Jacksonville-based investment bank, helped establish the company through its accelerator program.
