Firm Headquarters: US & Canada
Years of Operation: 5 – 9 years
Total Assets Under Management:
$50 – 99M
Total Number of Investors: Between 5 – 25
% of Capital from Top 3 Investors: Less than 25%
Investment Thesis:

We seek pre-seed and seed stage opportunities to partner with founders to generate financial returns and planetary impact from large markets that exist today (not decades from now) and customer groups who are making purchase decision regardless of policy or altruism.

Investment Overview:

Our investing focus is best described by the EU Article 9 “dark green” taxonomy with at least 80% expected to link directly to climate change mitigation and adaptation. Target investments are seed stage venture (Pre-seed, Seed, Seed+) with 80% North America, Europe & Israel. We support founders leveraging a unique global network that includes a curated community of 12k who receive monthly email updates that help get us to 130+ new deals per month. 50% of first customers and 50% of lead follow-on investors come from introductions to the 1k closest collaborators from our community. Our proprietary deal management platform enables deal sharing with LPs. Our in-house but separately managed series of credit funds provide additional types of capital and insights.

Company Differentiator:

We're a rare GP team in that we have a track-record of top returns over 14-year seed and 9-year climate investing history. We've built, operated, and sold both software and hardware firms. After 9-years together we hold top rankings from founders & investors. See Techcrunch "VCs who Founders love most", NfX Signal, Founders Choice, Climate50, and YC-Bookface for more.  We support founders leveraging a curated and expansive global network of investors, customers, experts, and talent.  Most generalist VCs aren’t focused on how to achieve planetary benefits, especially climate change mitigation and adaptation. Even the best early-stage investors (like YC) have limited track records backing unicorns that combine hardware and software. Few climate VCs understand rapid growth. Too many assume adoption driven by policy or customers desire to “do good”. 

Investment Example

Bowery Farming uses “post-organic” brand positioning and potential economics of indoor farms to carve a path to food supply chain resilience without requiring prolonged premiums. The platform opens up opportunities for not only future of food but also organic materials. The company is now at $2.3b valuation which we’re holding at 37x. Bowery is our investment in the future of more resilient food systems with lower carbon footprint food transportation. We were one of the first funds the founder called when starting Bowery. Shaun had been an angel investor in Irving’s (CEO and founder) previous company. We helped with investor intros, in particular to General Catalyst who co-led the series A. Co-investors include GGV, KKR, Temasek, General Catalyst, and GV.

Investments systematically target companies where social and/or environmental impact is integral to the product/service being created:

Each investment goes through an environmental and climate issue review during due diligence. This is a critical filter for whether we explore further or make a final investment decision. We create an impact investment memorandum for each investment, including a narrative of the company’s climate impacts and an explanation of the scoring process as well as key impact tracking factors. We look for companies that produce explicit positive externalities as part of our strategy, and therefore we seek to multiply that impact by making introductions to other portfolio founders where collaboration might help enhance their individual efforts. This is included in a list of "how we can help" action items at the end of the deal memo. 

Investments systematically include social and environmental sustainability practices in the due diligence process:

We do not invest in startups where there are signs of abusive behavior or toxic culture. We have a bias towards diverse teams and teams with diversity plans. Because we invest in early-stage companies, cost and lack of data are major barrier to generating climate analytics and reporting about our portfolio companies. We make up for this by collectively tracking all our investments to the SDGs as well as key areas of impact: GHG Emissions, Resilience, or Density in our portfolio tracking. As we grow the size of our investment capability and expect more returns on our early investments, we would be open to standardizing our method using a third-party ESG auditor or environmental accountant.
