(PressDemocrat) - A San Francisco venture capitalist is investing $2.5 million in H.D.D. LLC, a fast-growing Healdsburg wine company launched by partners Paul and Heath Dolan, Phil Hurst and Bill Hambrecht. The investment by Daniel A. Carroll, managing partner at TPG Newbridge Capital, will give the company additional resources as it prepares to introduce new packaging and begin selling wine online. The company sells wine directly to consumers, restaurants and retailers. It expects to sell nearly 250,000 cases this year and generate $20 million in revenues, up from $500,000 in 2008, its first year of operations.
