I think they are really a winner from the following perspective:
1. Have a large enough vision and market
2. Maintain high quality of user engagement
3. Hire a talent team
4. Found the right investors
These are pretty much what every successful startup company needs. But I'm curious about
1. How did they obtain a user base (especially enterprise level accounts in the US) and keep them from the competitors, especially when they didn't have any marketing hiring yet?
2. How are they able to attract the talented team members even they were small? The same for investors.
Looks like they have extremely good luck.
Can you refer some of them which may cover the above questions?
