Investor Profile: DBL Partners — Thesis, Cheque Size & How to Apply

Few firms can claim to have invented a category of venture capital. DBL Partners can. The San Francisco firm pioneered double bottom line investing — the idea that a venture fund should optimise both top-tier financial returns (the First Bottom Line) and positive social, environmental and economic impact (the Second Bottom Line). For founders seeking startup funding without the false choice between profit and purpose, DBL is the original proof that both can be won together — it was an early backer of Tesla.

Our thesis: impact without sacrificing returns

DBL was formed on the conviction that healthy financial performance and positive social change are inherently connected, not traded off. The firm invests through an impact lens in which social returns accrue without sacrificing financial returns, and works with each company on double-bottom-line practices — workforce development, community engagement and environmental performance — paced to the company's stage of growth.

Sectors and stages: Series A and B, with flexibility

DBL's sweet spot is Series A and B in Climate, Information Technology, Sustainable Products and Services, Healthcare and work-related themes. It prefers to lead, invests globally with a US focus, and will move earlier or later based on opportunity and portfolio construction. The team looks for founders trying to change the world, asks how a solution moves the needle on the overarching problem, and insists the impact be quantifiable.

Fund size and cheque size

DBL traces its roots to a fund started within JP Morgan, closing its first fund of $75 million in 2004. Its second fund, DBL Equity Fund (BAEF II), reported $150.8 million raised with backing from mission investors including The California Endowment ($10 million). Typical cheques run $5 million to $15 million. Current total assets under management are not publicly disclosed.

Notable portfolio

The firm's early bets read like a history of modern cleantech: Tesla, SolarCity, Pandora Media, Revolution Foods, The RealReal, BrightSource Energy, Ecologic, eMeter and Livescribe. More recent activity includes backing Fiber Global's $20 million round for waste-stream building materials — a textbook double-bottom-line deal combining sustainability, performance and affordability.

Partners

DBL is led by founder and Managing Partner Nancy E. Pfund, one of impact investing's most recognised figures, alongside Managing Partner Cynthia Ringo. Both have been with the franchise since its double-bottom-line beginnings.

Programs, credits and perks

DBL runs no public accelerator; its support is partner-led and board-level. The firm typically takes board seats and helps with recruiting talent, business strategy, fundraising support, impact metrics and engagement with policymakers and community groups. Its investment process is traditional — from a few weeks to a couple of months to a term sheet — with distinctive screening around team ambition and measurable impact.

How to apply for funding

DBL publishes no public application form or open pitch portal. Founders are directed to reach the team through the firm's website at dbl.vc — and should arrive ready to answer DBL's two defining questions: is your team trying to change the world, and can you quantify the impact?
