On the topic of A16Z v. Benchmark, especially from 09 onwards Benchmark has done ridiculously well. Early on Uber(a, b + c), Snapchat (a + b), Instagram (a + b), Dropbox (b), Nextdoor (a, b + c), Hortonworks (a, b), Zendesk (b, c + d), New Relic (a, b + c) and Twitter (c + d). I'm sure I'm missing a few as well.
I'd love for the fund data to be available!
