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. As the amount of data stored in MySQL grows, so too does the requirement to analyze this data for business decision making.

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. Prior to Kickfire, they founded Sanera Systems, a startup that focused on mission-critical, high-performance SAN switches.
