Any companies you're genuinely excited about? My list: Uber>. Not so much now that Kalanick was pushed out, but still keeping an eye on it. Airbnb Vizio>. Always looked like a good value product, seems like they've been bought so IPO may no longer be in the works.
The marquee US names are Airbnb, Dropbox, Lyft, Palantir, Pinterest, SpaceX, Spotify, Stripe, WeWork, Uber -- but there are hundreds of other unicorns.
