Goodmorning! Hope everyone had a great weekend. This week, we'll dive into GitHub's epic DDOS attack, the downstream ramifications of Spotify's move to GCP and a few items about DropBox as it becomes a public company. The most interesting piece about DropBox comes from Tom Tunguz, who parses the storage company's S1. He gleans a bunch of insights and compares DropBox's numbers to Box's but, his most interesting conclusion revolves around DropBox's successful freemium model, which it largely pioneered. We've included a number of articles about the benefits of freemium models - from marketing to product enhancements. It's fascinating to see the numbers come true in one of the largest SaaS IPOs in years.
