Arjuna Capital

Arjuna Capital was established in 2013 by Natasha Lamb after operating as a division of Baldwin Brothers. The firm spun out independently in 2016. It serves multiple families whose wealth originated in technology and growth sectors. The firm allocates across public equities, private equity, private credit, and impact funds. Confirmed positions include holdings in Apple, Nvidia, and Alphabet alongside commitments to New Summit Impact Fund IV LP and BlueOrchard Microfinance Fund. It maintains exposure in North America and Europe with additional reach into Asia. Shareholder engagement forms a core part of the approach on topics such as climate risk and gender equity. The firm employs a team that includes Farnum Brown as President and Alexander Lamb as Managing Partner. It operates two offices and participates in networks including US SIF and the Interfaith Center on Corporate Responsibility. March 2025 marked the merger of New Summit Investments into Arjuna Capital. Arjuna Capital maintains a hybrid structure that integrates direct fund commitments with activist public equity positions. This setup allows influence over both listed companies and private impact vehicles while separating advisory services from proprietary capital deployment.
