Keep in mind Michael Seibel is a co-founder of Twitch. Twitch is on extreme end of the monetization scale where it's success depended entirely on whether they could add free users fast enough to justify sufficient investment to bridge the gap until they could monetize via ads. The other end of the spectrum is enterprise software. In between you have self-service SaaS, premium consumer, and freemium consumer products. Each of these has very different requirements for what traction look like, all of it significantly less a pure ad-driven monetization like Twitch. The other dimension is how big you need to be to be considered successful. VCs need massive scale, and the bigger you grow the harder it is to maintain momentum, so it's gotta look really juicy at early stage to justify the growth. YC is not a VC, but as the premier incubator that feeds into the SV VC ecosystem they definitely have that lens.
