In the SV tech community, Dropbox, Uber, Snapchat, Spotify, AirBnB, Lyft, Netflix, Pinterest, Robinhood to name several.

Outside the tech community, probably Amazon, Microsoft, and Instagram (most people don't know Facebook owns Instagram).

Why is there a difference between inside and outside the tech community?

The economic success, brand awareness, and hipness of a company with the general public is only somewhat correlated with average level of engineering talent at a company. Different successful companies take different approaches to hiring - some focus on hiring a lot of reasonably competent engineers, while others focus on only hiring the best (and generally pay them a lot).

Are you saying the latter two don't do that?
