In the emerging clean economy, scale is the critical challenge. There are plenty of good ideas and proven technologies. But there’s a disconnect between entrepreneurs, investors, and large corporations in the market. Small companies need access to capital and global distribution channels. Large companies need more innovative approaches to address resource challenges. Investors need scalable commercial pathways to see a return. We founded Pure Energy Partners to connect these dots.
We’re veteran pioneers of the clean economy with decades of experience working at the highest levels of business, finance, and industry. As successful investors, entrepreneurs, and advisers we have started, grown, and sold multiple clean technology companies, raised and deployed many millions of dollars, and led the development of some of the most notable clean economy commercial initiatives.
Like a venture investor, we competitively select a portfolio of the most promising and impactful clean economy ventures. We then work intensively with our entrepreneurial, finance, and corporate portfolio companies to help them secure strategic customers, partners, and capital and drive more rapid growth. In turn, we earn a share of the value we create in helping them to achieve scale.
