Nikki Durkin has founded two companies, the first being 99dresses, a company that allowed women to trade fashion items with other users. 99dresses was a Y-combinator backed startup that had thousands of users and raised hundreds of thousands of dollars before having to shut down. For anyone who is interested in startups or looking to start their own, I highly recommend her post on Medium titled, My startup failed, and this is what it feels like. Nikki’s second startup is called CodeMakers, a company that teaches children how to code using Minecraft.
