About

DBL Partners is a San Francisco-based venture capital firm that pioneered “double bottom line” impact investing, seeking both top-tier financial returns and meaningful social, environmental, and economic impact 1. The firm traces its origins to 2004 when Nancy Pfund created the $75 million Bay Area Equity Fund I at J.P. Morgan, which made early impact investments including backing Tesla Motors in 2006 9. The fund spun out of JPMorgan in 2008, when Pfund and Cynthia Ringo partnered to raise Fund II ($150.8 million) 9. In 2015, DBL Investors merged with the cleantech practice of Technology Partners, led by Ira Ehrenpreis, to form DBL Partners and raised Fund III at $400 million 9. In 2021, the firm closed Fund IV at $600 million 15. The firm manages over $1.5 billion in assets 10.

DBL Partners operates from offices in San Francisco (One Montgomery Street) and Palo Alto (550 University Avenue) 1. The firm has invested in 72 companies, producing 4 unicorns, 6 IPOs, and 18 acquisitions 13. Notable exits include Tesla (IPO 2010), Pandora (IPO 2011), SolarCity (IPO 2012, acquired by Tesla 2016), The RealReal (IPO 2019), Planet Labs (IPO 2021), and NEXTracker (IPO 2023) 2 13. Portfolio companies have collectively created over 48,000 jobs 1.

The current team includes co-founders Ira Ehrenpreis and Nancy Pfund as Managing Partners 3 4, Partner Mark Perutz (who joined from JPMorgan’s Bay Area Equity Fund in 2008) 5, and Principals Vincent Caruso and Jake Harris 1.

The firm is a member of the UN Principles for Responsible Investment (PRI), the Global Impact Investing Network (GIIN), the US Impact Investing Alliance, and Climate 50 1.

Stated Thesis

DBL Partners publicly describes its mission as investing in “mission-driven founders building the future of impact and sustainability, without compromise” 1. The firm states it delivers both top-tier venture capital returns (the “First Bottom Line”) and positive social, environmental, and economic impact (the “Second Bottom Line”) with no tradeoff 1.

The firm’s stated investment focus areas for Fund IV include: clean energy and the electrification of everything, conservation and resources optimization, agriculture and food, space/Earth nexus, transportation and mobility, and future of work and human connection 14. The firm also states it invests across cleantech, information technology, sustainable products and services, and healthcare 1.

Ira Ehrenpreis has stated: “I really want to debunk the old view that to get top financial returns you have to give up social and environmental returns. It’s not a zero-sum game or a tradeoff if you back the sort of entrepreneurs we’re backing” 6.

Nancy Pfund has described the approach as: “There is no sacrifice: impact investing allows you to blend profit and purpose” 7.

Inferred Thesis

Based on 46 verified portfolio companies from the firm’s website 2, DBL Partners’ actual investment behavior shows the following patterns:

Sector distribution: Clean energy and climate tech dominate the portfolio. Of 46 verified investments: 16 are in clean energy, solar, or climate-related companies (35%); 7 are in agriculture, food, or nature-based solutions (15%); 6 are in space, transportation, or logistics (13%); 5 are in healthcare or life sciences (11%); 5 are in consumer/marketplace platforms (11%); 4 are in IT or enterprise software (9%); 3 are in other categories (7%).

Stage distribution: The firm invests across stages but favors Series A and Series B. Based on Tracxn data: 15 investments at Series A (average round size $11.9M), 13 at Series B (average round size $41.4M), and 3 at Seed (average round size $4.47M) 13. This indicates a preference for companies with some traction rather than purely pre-revenue startups.

Geographic concentration: The portfolio is heavily concentrated in the San Francisco Bay Area and California more broadly, consistent with the firm’s origins as the “Bay Area Equity Fund” 9. Some investments extend to other US locations and internationally (e.g., Andela in Africa, ZOLA/Off Grid Electric in Tanzania) 2.

Founder diversity: DBL reports that 43% of deployed capital in Fund IV is invested in women-led companies, and 30% of Fund IV companies have BIPOC founders 14. This is far above the industry average of 2-4% for women-led companies 6.

Elon Musk ecosystem: A notable pattern not explicitly stated in their thesis is heavy investment in companies associated with Elon Musk. The portfolio includes Tesla, SpaceX, SolarCity, The Boring Company, and xAI 2. Ira Ehrenpreis has served on Tesla’s board since 2007 3.

Co-investor patterns: The firm frequently co-invests with other impact-oriented and cleantech-focused investors. Notable co-investors across multiple deals include Andreessen Horowitz (Apeel Sciences), GV/Google Ventures (Farmers Business Network), and VoLo Earth Ventures (Rain) 11 12.

Gaps between stated and actual: While the firm emphasizes “no tradeoff” impact investing, several portfolio companies (xAI, The Boring Company) have tenuous connections to the social/environmental impact mission. The space/Earth nexus and AI categories appear to be recent expansions that stretch the traditional double-bottom-line framing.

In Their Own Words

“I really want to debunk the old view that to get top financial returns you have to give up social and environmental returns. It’s not a zero-sum game or a tradeoff if you back the sort of entrepreneurs we’re backing.” — Ira Ehrenpreis, Founder and Managing Partner, VentureBeat Blueprint summit, 2018 6

“There’s an unprecedented wave of entrepreneurs right now who don’t believe in those tradeoffs. They don’t buy into the 18th or 19th century idea that you make money by day and think about your mission at night.” — Ira Ehrenpreis, VentureBeat, 2018 6

“We wanted to find those left behind and use entrepreneurship to catalyze economic development and job opportunities.” — Ira Ehrenpreis, VentureBeat, 2018 6

“I’m happy to say we’re not at the two to four-percent venture capital average: Right now 57 percent of our companies are women-led. We don’t invest in women-led companies because they’re led by women. We invest in great entrepreneurs who happen to be women.” — Ira Ehrenpreis, VentureBeat, 2018 6

“There is no sacrifice: impact investing allows you to blend profit and purpose!” — Nancy Pfund, CleanTechnica interview, March 2019 7

“I’m driven by belief in equity, inclusion, and sustainability. I believe in using evidence-based decision making to take the politics out of the critical problems of our era, such as climate change.” — Nancy Pfund, Yale Insights, 2018 8
