47 Startups That Launched At Y Combinator Winter 2015 Demo Day 2

Y Combinator got so big, it had to split its Demo Day in two. During today’s second wave we saw a variety of promising biotech, marketplace, enterprise, and financial tech startups. Yesterday we chronicled 50 consumer, B2B, developer, and hardware companies.

With bigger and bigger batches, the on-stage pitches are getting more bombastic as YC’s startups compete for attention. Yet this batch seemed like one of the strongest in years. After some batches around 2013 that included startups that felt more like niche features, YC is now backing big dreams for the future of medicine, money, and even marijuana.
