Variety: Snapchat didn’t just file SEC documents for a massive new $1.8 billion round of funding last week, the company also had its pitch deck leaked, revealing some interesting insights into the company’s usage and revenue. Particularly striking: Snapchat may already have more daily active users than Twitter. Snapchat’s explosive growth should bother Twitter and its investors, especially if Snapchat succeeds at selling its users to brands that would have otherwise advertised on Twitter.
