As seen over the past few years, Big Data has become a lucrative business. Just look at the hot IPOs from operators like Splunk SPLK +0.23% (SPLK) and Tableau Software (DATA).
For the most part, these early players have focused on solutions that are broad. If anything, this is fairly typical for any new tech trend.
But as the Big Data industry begins to mature, we are now seeing a variety of startups that focus on verticals. For example, one that has gotten traction is TrendKite, which has developed a predictive analytics platform that measures the ROI for marketing and communications efforts. It has customers that range from small businesses to Fortune 500 companies.
