They have historically been one of the biggest movers in Chinese and Indian Growth VC, and have a significant presence in American Growth VC too.
They made oodles of money off Slack and DoorDash for example, and their 2010s investment phase was thanks to them being flush with profits from Alibaba and Tencent.
At the end of the day, compared to most other Growth Funds, they tend to hire some solid investors who know how to find capable operators.
Though, lapses of judgement do happen a la Neumann, but that's like saying anyone who invested in Pivotal or Joyent is dumb. This is VC. It's not guaranteed returns. There's a reason why it's called VENTURE capital.
Their hits have more than made up for their misses.
