Blue Bottle Coffee Inc., the Oakland, Calif., company known for getting its coffee to consumers within 48 hours of being roasted, has apparently taken in just under $20 million in equity financing, according to a recent SEC filing. Index Ventures’ Mike Volpi and True Ventures’ Tony Conrad are listed as directors at the company, according to the filing. Blue Bottle had already taken in some venture money previously, with an undisclosed investment from Kohlberg Ventures. Begun in Oakland in 2002 by James Freeman, Blue Bottle’s revenue has reportedly grown by upwards of 50% annually, to somewhere between $15 million and $20 million last year, Freeman told the Wall Street Journal in February. So far, the company has spread operations from Oakland to locations around New York – even a “little shed” on Rockaway Beach — and will likely use the infusion to expand further.
