Six years ago, we looked at a sampling of the startups that were at the Y-Combinator event, which is, for those of you who aren't douchebag tech-bros, some big event where rich idiots dump their money into a bunch of startups that will likely fail. We made fun of each and every one of these ideas, while knowing nothing about them. Today, we're checking in to see how these companies are doing. Our assumption is that they're all thriving businesses that are a boon to their respective communities. Give it a listen and see how right we are.
