The document discusses issues with the current state of cleantech venture capital investing and provides recommendations for improvement. It notes that most cleantech exits have been through acquisitions rather than IPOs. It also notes that VCs are investing larger amounts into later stages and only a few subsectors like solar, biofuels and electric vehicles. The document recommends that VCs invest in more capital efficient early stage companies, focus on areas outside of California and Massachusetts, and build profitable companies that are natural acquisition or IPO candidates rather than betting on rare "black swan" outcomes.
