eBay. Uber. Twitter. Snap. Discord. All Benchmark companies. Here's who's hiring next.

Benchmark doesn't raise billion-dollar funds. They raise $425M — and make roughly 10 bets per fund. No junior partners. No spray and pray. Just five general partners who take a board seat with every company they back.

That selectivity is the point. When Benchmark invests, it's a signal. And right now, 14 of those companies are hiring.

I track startups worth watching in AngelsRound — the kind investors follow before they break out. This is the list.
