Meet the 2015 CNBC Disruptor 50 companies

In the third annual Disruptor 50 list, CNBC features private companies in 16 industries—from aerospace to financial services to cybersecurity to retail—whose innovations are revolutionizing the business landscape. These forward-thinking upstarts have identified unexploited niches in the marketplace that have the potential to become billion-dollar businesses, and they rushed to fill them. In the process, they are creating new ecosystems for their products and services. Unseating corporate giants is no easy feat. (Tweet this.)
