This week a New Hampshire analytics startup announced a massive funding round, Tableau filed for an IPO, and IBM unveiled a new Big Data appliance that embodies the culmination of its analytics efforts so far.

Deep Information Science raised $10 million in a first round of funding from Stage 1 Ventures, Robert Davoli and a number of other investors. The company, which changed its name from CloudTree, sells a platform that facilitates simultaneous, real-time transactional and data analytics on the same data set.

Tableau, a prominent provider of BI and data visualization software, also had big news this week: the company filed for an IPO. The S-1 filing specifies that Tableau is hoping to raise up to $150 million, and that its stock will trade under the symbol DATA. The document also reveals that the firm has 9 patents to its name and another 8 pending applications, which means that we can expect new product announcements in the foreseeable future.

IBM didn’t have any exciting financial news this week, but it did announce a new appliance and a set of accompanying analytics software we’ve nicknamed the IBM Big Data stack.

PureData for Hadoop is an all-in-one box that can be set up in less than two hours. The hardware runs BLU Accelerator, a set of four technologies based on more than 25 patents.

BLU features columnular data processing, “single instruction multi-data” acceleration architecture, a compression technique that eliminates the need for decompression, and a system that identifies and then skips irrelevant data.  This bundle is supplemented by the latest version of IBM Infosphere Streams, an upgraded SQL interface for Hadoop, and a couple of other tools that are also pre-integrated into PureData.
