I'd like to know what major companies are in BerkeleyI think that the energy bar companies retail in TN, Clif Bars and Luna Bars. The Nature Company is nationwide, stores in malls and a mail order catalog. Peachpit Press - software, Nolo Press - do-it-yourself legal books used to be there I think it still is.
I'll check those out. Meanwhile, here is a list of businesses listed with the Berkeley Chamber of Commerce. Not all are BASED in Berkeley, but I'm sure there are some on that list that ARE based in Berkeley.
