Flex Seal is an American brand of adhesive bonding products made by the family-owned company Swift Response in Weston, Florida. Founded in 2011, the company employs 100 people led by its pitchman and chief executive officer Phil Swift. Flex Seal has become a popular internet meme because of its television advertisement demonstrations of the product in absurd and exaggerated situations, such as a boat sawed fully in half and made seaworthy again with the product.
