Hundreds gathered this week at San Francisco’s Pier 48 to see the more than 200 companies in Y Combinator’s Winter 2019 cohort present their two-minute pitches. The audience of venture capitalists, who collectively manage hundreds of billions of dollars, noted their favorites. The very best investors, however, had already had their pick of the litter.

What many don’t realize about the Demo Day tradition is that pitching isn’t a requirement; in fact, some YC graduates skip out on their stage opportunity altogether. Why? Because they’ve already raised capital or are in the final stages of closing a deal.
