If you read section #1 in the article, you'll note that there are a lot of bad picks out there. To review: - 4,000 startups a year. - 3,000 seen by a16z. - 200 are "fundable." - 15 of those generate 95% of returns. If a single VC firm were to fund all 4,000 startups (or even a representative sample of them), they'd be out of business in a few years. A "startup index" unbiased by due diligence is a pretty bad idea from an investor perspective. That said, if you want an example of a seed fund with a pretty broad approach, take a look at the aptly-named 500 Startups.
