Here are some highlights:
- Ownership: Weibo is owned and controlled by Sina Corp. which has 77% of the shares. Alibaba group, a Chinese e-commerce company, invested $585.8 million and owns 18% of the company, with an option to increase its stake to 30%. (Yahoo owns 24% of Alibaba.)

- Net loss in 2013: $38 million (its net loss is declining).
- 129 million monthly active users. (Twitter has 241 million MAUs.) Users generate 2.8 billion feeds a month. Interestingly, Weibo is much smaller than previously thought. It's less of a threat to Twitter.
- 70% of Weibo users are on mobile devices.
- Revenue per user is roughly $1.45. (Twitter's RPU is roughly $1.49.)
- Weibo's Alibaba alliance will bring it $380 million in revenues through 2015.
