The vegan shopping platform, Billion Vegans, focuses on quality and verification for the products they sell on-site. All 4,500-plus items have been vetted by the website's team to be 100 percent vegan, something co-founder Alon Hochberg felt was missing from giants like Amazon. He got the idea for Billion Vegans after a pair of vegan shoes he ordered off of Amazon were found to use a glue made from pigs' bones, so this verification step is huge for his business model.
