Despite the fact that the 140-character microblogging service is unprofitable and lost about $70 million so far in 2013 alone, it's still apparently worth billions of dollars. And it's also about to make the following individuals mentioned below very, very rich:


Jack Dorsey, co-founder and executive chairman: $679 million

Total shares owned: 23,411,350 (4.9%)


Dick Costolo, CEO: $220 million

Total shares owned: 7,589,608


Ev Williams, founder and largest individual stakeholder: $1.65 billion

Total shares owned: 56,909,847 (12%)


Adam Bain, president/global revenue: $50 million

Total shares owned: 1,722,350


Series G holders - Yuri Milner’s DST, T Rowe Price, Chris Sacca and others: $696 million

Total shares owned: about 5%, or 24 million


Union Square Ventures: $696 million

Total shares owned: about 5%, or 24 million


Peter Currie, board member: $8.5 million

Total shares owned: 291,666


Benchmark Capital: $915 million

Total shares owned: 31,568,740 (6.7%)


David Rosenblatt, board member: $8.2 million

Total shares owned: 283,333


Series C and D holders Rizvi Traverse and Spark Capital: $680 million

Total shares owned: 24 million (about 5%)

Since Rizvi is reportedly backed by Sacca, that means the latter owns a combined stakes worth more than $1 billion.


Peter Chernin, board member: $3.7 million ... plus lots of restricted stock


MoPub stockholders: $429 million

Total shares owned: 14,791,464

And here are the ones who might be losing out on the IPO filing:


Noah Glass, the "forgotten" founder: $0

Not mentioned in the IPO and seems to have dropped off the Internet. Apparently reached some sort of settlement with Twitter months ago that gave him some cash. It is not known how much.


Biz Stone, founder: $0

Total shares owned: None listed
Not mentioned in the S-1, may have already have sold his entire stake to other investors prior to the IPO.


Christopher Fry, svp engineering: $0 ... but lots of restricted stock

Twitter says, "Mr. Fry holds RSUs, none of which will be vested within 60 days of August 31, 2013."
