3i is a leading international venture capital and private equity firm that was founded in 1945 to invest in buyouts, growth capital and venture capital in order to create market-leading companies. Since its inception, 3i has invested over $32 billion worldwide and has a staff of 700 employees operating in 14 countries.

In the U.S., 3i invests in early and late stage technology companies in the software, communications, semiconductor and healthcare sectors. We have offices in Menlo Park, Calif. and Waltham, Mass.

3i’s cleantech investments reflect the breadth of technologies that come into play and that can be considered "clean technology" – those that optimise the use of natural resources while reducing ecological impacts – such as software, chips, advanced materials, fuel cells, water treatment systems, wave energy converters and more.

Technologies in the sector tend to fall under one of the 11 segments: agriculture; air and environment; energy efficiency; energy generation; energy infrastructure; energy storage; manufacturing/industrial; materials; recycling and waste; transportation; and water and wastewater.

Within the clean technology sector we have invested in many companies including: Konarka (solar), Amperex Technology (battery technology), Electawinds (wind), and Daalderdrop (efficiency HVAC and solar).
