[Update 12/11: Twitter filed regulatory papers saying it had raised $4.8 million in a second round of funding, and that it possibly raise a total of $5.4 million]
Confirming what we first reported earlier this week, the fast-growing Twitter messaging service has raised a new round of funding.
The San Francisco company, which has become popular among people wanting to update online what they are doing at any given point of time, has announced the lead investor on the deal, which we hadn’t known earlier: Union Square Ventures, of New York.
The amount was undisclosed. Other investors include CRV, Marc Andreessen, Dick Costolo, Ron Conway, and Naval Ravikant, among others.
Union Square’s Fred Wilson blogs about it here.
This is an well-timed present for Evan Williams, owner of Obvious, the original parent of Twitter and now large stakeholder, who is getting married tomorrow.
