SJF Ventures

SJF Ventures is a Durham, North Carolina-based venture capital firm focused on growth- and early-stage investments in cleantech, sustainability, and technology-enabled services across the United States. Founded in 1999, it backs companies with annual sales typically between $2 million and $30 million and enterprise value under $50 million, investing roughly $3 million to $10 million per portfolio company and up to $15 million over the life of a company. It seeks to lead or co-invest in syndicates, sometimes alongside debt with warrants, and aims to take a board seat. Portfolio companies operate in sectors such as energy efficiency, water and waste technologies, renewable energy, sustainable agriculture, health and wellness technology, education technology, and digital services leveraging software and data. The firm pursues rapid sales growth, profitability, and premium exits through strategic mergers, initial public offerings, or buyouts, with a five-year or shorter investment horizon. It maintains offices in San Francisco, New York, and Richmond, in addition to its Durham base.
