Are the numbers for Series B & C still representative of what founders are getting in tech today? They seem about right for Web 1.0 dot-com boom days, but looking at some of the financings on TechCrunch, recent startups (eg. Twitter, AirBnB, Uber, DropBox) seem to be raising $30-100M Bs for about 5-10% of the equity and $100M+ Cs for under 10%.
