TrendSpottr is a company that uses big data to predict future trends. It was able to spot and predict that a photo of President Obama would go viral just minutes after it was published using its analysis of social media, news, and other data sources. TrendSpottr then sent out an alert to its customers, allowing them to optimize their marketing and ad campaigns around the emerging trend, which resulted in increased engagement and sales for those customers. TrendSpottr's predictive alert system enables companies to identify trends early and adapt quickly.
