In 2015, the public markets for analytics companies experienced a turbulent year, with some companies struggling while others positioned themselves for future growth. Informatica was taken private for $5.3 billion, reflecting its exposure to the growing use of Hadoop, while Hortonworks faced a decline in stock value due to challenges in balancing license and services revenue. Teradata saw a significant drop in value as it struggled to compete with newer analytics databases and open-source alternatives. Meanwhile, Qlik and Tableau remained stable, although Qlik faced slowing revenue growth, and MicroStrategy's future appeared uncertain despite a modest stock increase. Companies like Microsoft, Salesforce, and Amazon emerged with strong competitive positions, poised to expand their influence in the analytics and big data markets. Microsoft enhanced its analytics capabilities with Power BI and the acquisition of Revolution Analytics, Salesforce eyed expansion with Wave Analytics, and Amazon introduced Quicksight, leveraging its dominant cloud hosting service, AWS, as a strategic asset. The year highlighted the challenges and opportunities in the analytics space, with significant shifts expected in the coming year.
