SJF Ventures is a venture capital firm founded in 1999 and headquartered in Durham, North Carolina, with additional offices in New York, San Francisco, and Richmond, that focuses on growth-stage investments in the United States across sectors such as energy, mobility, circular economy, logistics, sustainable food, health and wellness technology, education technology, and related technology-enabled services. The firm targets resource efficiency and sustainability opportunities, often investing between $1 million and $10 million per portfolio company, and frequently leads or co-invests in growth rounds while seeking to partner with teams delivering rapid sales growth and profitability alongside measurable environmental and social impact. It pursues exits within roughly five years through strategic mergers, IPOs, or buyouts, takes board seats, and can deploy equity and sometimes debt with warrants. SJF emphasizes impact alongside financial return, prioritizing companies with market validation and scalable models in cleantech, energy efficiency, waste reduction, sustainable agriculture, and digital services, primarily within the United States.
