Leveraging FINTRX family office data, which provides insight into thousands of direct deal transactions made by over 4,300+ family offices globally, we spotlight three family offices making direct investments in sustainable and renewable energy companies. 

1. Kohli Ventures

Founded in 2010, Kohli Ventures is a London-based single family office managing the wealth of entrepreneur and philanthropist Tej Kohli. Kohli built his fortune through a series of successful ventures in the technology and real estate sectors. Today, Kohli Ventures operates with a future-focused investment strategy, targeting exponential growth opportunities driven by rapid technological advancement.

The firm makes direct investments across a range of industries, with particular interest in artificial intelligence, biotechnology, robotics, and e-sports. Kohli Ventures is especially drawn to impactful ventures—those with the potential to improve human life and benefit communities at scale. In August 2015 and January 2016, the firm invested directly in Zynergy Group, an India-based company providing comprehensive solar energy solutions, including integrated solar power plants, inverters, lighting systems, pumps, and compressors. Since its founding in 2011, Zynergy has played a key role in advancing solar energy adoption throughout India.

In June 2019, Kohli Ventures invested in Rewired, a private AI and robotics-focused investment vehicle launched in 2017. Rewired initially committed $100 million to support the development of technologies that help robots navigate real-world environments, make real-time decisions, and enhance human productivity. Geographically agnostic in its approach, Kohli Ventures has made investments in countries including the United States, Canada, France, Argentina, Hong Kong, and the United Kingdom.

2. Pi Investments 

Pi Investments is an Oakland, California-based single family office managing the wealth of an undisclosed high-net-worth family. The firm invests across a broad range of asset classes, including private equity, venture capital, public equities, real estate, real assets, and direct investments. Deeply committed to socially responsible investing, Pi focuses on backing organizations that support a global transition from an extractive economy to one that is sustainable, inclusive, and regenerative.

Before allocating capital, Pi rigorously evaluates whether each investment contributes more value to communities and the environment than it extracts. The firm prioritizes ethical production models that meet real human needs rather than create artificial demand. In direct company investments, Pi emphasizes long-term partnerships, supporting management teams while maintaining a strong commitment to both financial discipline and measurable impact.

In November 2015, Pi Investments made a direct investment in CleanChoice Energy, a clean energy supplier dedicated to making renewable power accessible to all. The company allows individuals to support 100% clean wind and solar energy without the need to install solar panels or own their home or business space.

When investing in alternative funds, Pi conducts in-depth assessments of each fund manager’s dedication to impact, adaptability, and efforts to drive systemic change in the financial ecosystem. The firm also actively seeks co-investment opportunities with like-minded family offices, entrepreneurs, institutions, and high-net-worth individuals who share its mission-driven approach.

3. United Green

With roots dating back to the early 20th century, United Green is a Mayfair, UK-based single family office managing the assets of an undisclosed high-net-worth family. The firm provides comprehensive investment management services, including deal origination, due diligence, and risk management. United Green oversees a globally diversified portfolio spanning renewable energy, infrastructure, fast-moving consumer goods, commodities, manufacturing, construction, trade, agriculture, specialty lending, nutrition, and technology. Its investment strategy focuses primarily on private equity, venture capital, and real estate.

In the renewable energy space, United Green invests in large-scale wind and solar projects across Europe, the Middle East, and Asia. Its technology investments target both emerging and established companies in the UK and the Middle East, while its venture capital arm focuses on seed, early-stage, and growth-stage opportunities. The firm aims to create long-term value in sectors and regions with high barriers to entry, whether financial, technological, or political.

In July 2020, United Green made a direct investment in a 300-MW direct current solar project developed by Renew Estate in Queensland, Australia. Once operational, the plant is expected to generate 625 GWh of electricity annually—enough to power approximately 88,000 homes—and will include an integrated battery storage system with approved planning. United Green remains active in emerging markets and is open to co-investments and strategic joint ventures.
