Here are a few broader observations to share:
Startups are a long term endeavor - On average it took ~11 years for these companies to go public.
Expect more market uncertainty - While it’s awesome all of these solid technology companies are going public, this rush of filings is most likely pointing towards more market volatility, especially as we get closer to November.
Concentrate and follow through - While spray and pray investing (small checks into lots of companies) is all the rage in Silicon Valley right now, the real winners are the firms who were able to stick it out and maintain 20%+ ownership through IPO. These phenomenal firms include - Sequoia, Greylock, and Sutter Hill Ventures.
Disclosure: I previously worked at Greylock Partners.
