What are you working on?
jdrock: http://www.80legs.com - web-scale web-crawling for everyone.  Launched in September and growing revenue now.  We've solved a lot of big data store issues in our back-end.  Challenges have shifted from technical to business :)Extractiv - web-listening and content-extraction that combines semantic analysis and web-scale reach for a complete picture of what information is on the web and what the web is discussing.  The core technology is working, currently turning it into a real product.
