Craton Equity Partners invests in water remediation, waste conversion and 'green' building materials. Craton Equity Partners began in Los Angeles in the mid 1990s as an investment fund focused on small companies in need of growth capital in the basic industry and manufacturing sector. The firm pursues companies that are involved with clean technology for energy generation, water treatment and other environmentally responsible activities. Craton targets small companies with total enterprise value of less than $50 million, focusing on companies that are undercapitalized, but have a proven business development history in traditional areas of technology application.
