Highly Likely Rumor: Twitter Closes Third Round Of Financing From Spark Capital
A source says Twitter signed a term sheet with Spark Capital a couple of weeks ago, and Spark partner Bijan Sabet was in San Francisco today visiting “a very special company.” Other hints on Twitter: cofounder Evan Williams remarked that he was walking down Newberry Street in Boston late last month – my guess is he walked right into the building at 137.
Spark Capital also tends to work closely with Union Square Ventures, one of the existing investors in Twitter. See the investors, for example, in Tumblr, Covestor and Bug Labs.
Nothing is confirmed yet by the company, but I suspect it will be shortly. And it certainly explains the good mood they’ve been in lately, despite the increased downtime (see update here).
