Cazoodle: provides software and internet services for Web search, integration, and mining, with a central objective to "deepen" search on the Web-- to access the vast amount of data beyond the reach of current search engines. The company is co-founded by Prof. Kevin C. Chang and his research team, with the support of the University and technology transfer from the MetaQuerier research at Illinois. 

PatternInsight: YY Zhou and 3 of her researchers - Zhenmin Li, Spiros Xanthos, and Qingbo Zhu - launced PatternInsight based on technologies they developed in their labs.  PatternInsight brings powerful data mining technology to the advanced, real-time analysis of every type of system data—code, logs, scripts, and more. 
 

Surf Canyon: Cheng Zhai's “real-time implicit personalization” technology, which improves relevancy by re-ranking search results “on the fly” based on a user model generated from real-time selections.  The research technology was licensed to Surf Canyon and has been enhanced by Zhai and current CS students.

Visual Information Technologies: VIT uses professor Dan Roth's search visualization tools to create a new digital media communications platform called VizMo.

LLVM: Vikram Adve’s Low-Level Virtual Machine compiler (LLVM) is licensed under Open Source licensing.  His technology is currently in use by companies like Apple, Adobe, Aerospace, Cray, Ageia, and NASA. 

SolidWare: Former Illinois PhD student and current Berkeley Professor Koushik Sen has licensed technology he worked on as a PhD student in Gul Agha’s lab. The CUTE and JCUTE tools systematically and automatically test sequential C programs (including pointers) and concurrent Java programs.  The technology was later acquired by Coverity.
