Greentech has emerged as one of the hottest sectors for venture capital funding within the past few years. Today we introduce some of the major players driving this trend. Below, as reported by New Energy Finance, the top five greentech investors of 2008 are ranked by their number of transactions, with total deal value listed as well. The deal values are not entirely accurate, however, as numerous deal values were undisclosed.
[1] Good Energies (21 deals/$65.3m)
As in 2007, Good Energies claimed the top spot, this time participating in twenty-one deals sprayed across a variety of sectors, development stages, and countries. The seemingly low $65.3m figure is misleading due to the presence of fifteen deals with undisclosed values.
[2] Draper Fisher Jurvetson (20 deals/$102.9m)
In addition to leading segments solar and biofuel, Draper heavily focused on early stage companies in the energy efficiency and energy storage segments. Efficiency companies Luminus Devices and Tesla Motors, alongside solar thermal startup BrightSource Energy, headlined DFJ’s list of deals.
[3] Kleiner Perkins Caufield & Byers (16 deals/$187.2m)
Famous for successful tech investments in Google and Amazon, KPCB has recently bet big on greentech. Its $187.2m topped the list for transactions value in 2008, mostly focused in efficiency and biofuel.
[4] RockPort Capital Partners (14 deals/$166.3m)
Solely a greentech-focused VC, RockPort poured money into all areas of the efficiency segment, ranging from green building (Aspen Aerogels) to supply-side efficiency (Powerspan) to digital energy (Northern Power Systems). Investing in both early-stage and late-stage companies, RockPort also made investments in solar and fuel cell technology.
[5] Khosla Ventures (14 deals/$111.5m)
Already notorious for making big bets in greentech, former Sun co-founder Vinod Khosla’s firm kept busy once again in 2008. In particular, biofuel was a major area of investment, including large raises for Range Fuels, Amyris Biotechnologies, and Mascoma.
