Twitter VC Funding Done, Raises $15M

I spent most of the day digging up more information on Twitter and its new round of funding that I reported last night. The update is that Twitter reached an agreement with investors today to raise $15 million in funding at around $80 million pre-money valuation. A new investor is leading the round with existing investor Union Square Ventures also participating. With this round, the company will have raised a little over $20 million in VC backing thus far.

Official news of the deal is eventually going to percolate out, and hopefully I will be able to nail down the specifics on who is the lead investor. Valleywag and Silicon Alley Insider had mentioned Spark Capital as a potential investor. Meanwhile, I am told that Charles River Ventures, after fighting a bit, is now out of the race. The news of new funding comes at a time when Twitter is dealing with a whole slew of scaling and infrastructure issues. Today, the folks there almost threw their proverbial hands up in despair.

Update: Twitter the great facilitator of e-narcissism also can’t keep secrets. As Michael Arrington points out, two tweets from two parties add fuel to the rumors of Spark being the mystery investor in the San Francisco company.
