Kickfire Analytics

Series B in 2008
Kickfire makes an analytic appliance for the MySQL data warehouse market. With 11 million active installations, MySQL is the world's most popular open source database and its adoption is accelerating.

However, the technologies required for data warehousing and high-performance query and reporting within the leading proprietary databases such as Oracle and SQL Server don't exist in MySQL. Kickfire has the answer. By combining hardware and software innovations with the ease-of-use of the MySQL open source database, Kickfire brings to market an analytic appliance with unheard of performance, simplicity, and economics. At the core of every Kickfire appliance is a new SQL chip that radically alters the economics of query processing by packing the power of 10s of CPUs into a single chip. Just as NVIDIA moved graphics processing from software to hardware, Kickfire has done the same for database operations. This disruptive innovation facilitates tremendous improvements in speed and reductions in cost and power. With Kickfire, the MySQL data warehouse market now has a fully functional, load-and-go analytic appliance that rivals any of the proprietary database appliances or specialized analytic databases in the world. And there is no expensive hardware buildout or complex tuning required. Kickfire was founded in 2006 by Raj Cherabuddi and Joseph Chamdani, two proven entrepreneurs with more than 50 issued patents.
