Have you ever wondered what CMS Shark Tank contestants use the most? We pulled together a list of every contestant to ever appear on ABC’s Shark Tank (Season 1-5) and identified their websites. We ran every site through Builtwith and manually investigated some of the more complex technical set ups. We then dived in and analyzed at a ton of interesting factors like if the site was still active, site-wide SSL implementation, what kind of ecommerce solutions were being utilized. We’ve put together our most interesting findings in this infographic.
