Stats & Data
A few months after publishing the 2021 Diamond List, we sent out an initial feedback survey to nominated climate startups. Of the received fractional feedback, we learned that the Diamond List resulted in startups receiving at a minimum:
Over $3 million in investment thanks to connections made through the list
Inbound interest from job seekers who learnt about their work through the list
Media coverage, including articles, social media coverage, and requests to be featured in climate-focused films and documentaries
"Efforts like Diamond List are foundational in raising awareness of leading climate tech startups and elevating the field as a whole. While early-stage climate companies can be perceived as riskier to both investors, as well as, awesome tech talent, the truth is that there is unprecedented upside in these opportunities. As a climate investor, two of the things I spend the most time on are helping portfolio companies hire and raise their next round -- Diamond List accelerates both by helping to unlock access to more capital and talent."
--- Lily Bernicker, Principal @ Wireframe Ventures
"As a pre-seed startup, the Diamond List has immensely valuable to us. It has given us exposure to many new investors who have been a great fit for us. The Diamond List already has the feel of a strong community, and I hope it continues to grow this influential network."
-- Eric Chaves, CEO @ Terrament

Notes about the data:
Eligible startups were series A and earlier
We accepted nominations from VCs, angels, accelerators, and family offices that have made at least two climate investments - and often over fifteen.
Despite receiving nominations, Frost Methane was excluded from the list as Olya is a co-founder of both the Diamond List and Frost Methane, and she would like to avoid conflict of interest.
While we did our best for an international reach, our network is strongest within the US, and the nominations reflect that. We’ll do better next year—if you want to help in this respect, contact us at email@example.com.
We excluded startups that were nominated but did not expressly consent to appear on the list by replying to our survey. If you were one of these startups and you’d like to be on the list after all, contact us at firstname.lastname@example.org

What is the Diamond List?
Published once per year, the Diamond List is a list of climate startups that have been nominated by qualified climate investors.The Diamond List enables:
- Climate investors to access a list of nominations submitted by other qualified investors, helping with deal-flow
- Nominated climate startups to receive additional exposure, which has historically led to press coverage and further VC investment
Why was the Diamond List created?
The Diamond List is an attempt to surface the untapped gems in climate — early-stage companies that deserve investment, but have so far been overlooked. Investment in climate ventures increased 40x in the last 6 years, but the sector is still experiencing growing pains, some of which the Diamond List can help solve:
- Angel investors, philanthropies and VCs new to the space have the risk appetite to support promising, early-stage companies but smaller staffs and fewer resources to do the due diligence and keep up with all the new regulation and climate market changes.
- VCs regularly turn away strong teams with high potential because of thesis fit or the opportunity is just a little too early or too risky at that time.We decided to help bridge these groups and ask leading climate investors to spotlight the strongest early stage climate companies so that they could reach high risk capital and get to scale and profit faster.
Inspiration for the Diamond List
We modeled Diamond List after Hollywood’s Black List for under-the-radar screenplays. Since 2005, the Black List has uncovered hidden gems such as ‘Argo’, ‘Juno’, ‘Slumdog Millionaire’, and ‘The King’s Speech.’ Black List films have grossed over $25 billion and have been nominated for over 240 Academy Awards, winning more than 45.
I am the CEO of Frost Methane. I was previously a system architect at Zola Electric, working on early stage climate projects at Google X, a team lead at Google Energy. Starting Frost Methane, I thought I was in a great position: deep domain expertise, super talented friends that jumped in to build our first prototype and install it in Alaska, amazing network, some cash cushion to self-sponsor our first deployment and not take a salary for a while. Yet, getting Frost Methane from idea to where it is today was by far the hardest thing I’ve done and wouldn’t have been possible without the early support of the Mulago Foundation and Lowercarbon Capital.I co-founded the Diamond List to match the philanthropic, angel and nonprofit capital and resources that want to flow to climate change with super promising early stage startups that need it. To give amazing founders with brilliant climate mitigation ideas the same shot at turning their visions into reality that I got.Frost Methane is ineligible for the Diamond List to avoid any possible conflict of interest. Any reference to it will be scrubbed from the final list.
ZEINA FAYYAZ KIM
I am an operating partner at Climate Capital Collective (C3) and Head of Strategy & Programs at The Plant, a global home for climate solutions. Previously, I was chief of staff at Imbellus, an assessment technology company, where I managed fundraising ($50M Series B) and M&A (sold to Roblox). Prior to Imbellus, I held grantmaking and investing roles at Chan-Zuckerberg Initiative, NewSchools Venture Fund, Goldman Sachs, and Sonen Capital. I started my career running accelerator programs—one with a geographic focus on New England and one with a population focus on American Black males. The latter was born out of President Obama’s My Brother’s Keeper initiative and ran in partnership with Open Society Foundations and the Campaign for Black Male Achievement.
I am a socially focused investor who previously helped lead investments for the Google alumni community, a California based PE firm, and an Atlantic Canada based family office. I have worked product, data analysis, and anti-abuse roles at companies including Google, Facebook, and Dataminr. I previously co-founded a renewable energy startup with my close friend Sam Levac-Levey, which led me down the VC path. I help organize the Work on Climate community; a group of high skilled individuals looking to have climate impact through work & volunteering.
I am a software engineer by training and in July 2020 I left Google Research with my friend Eugene Kirpichov to see what I can do for the climate crisis. Since leaving Google, Eugene and I have spoken with over a hundred people in the climate ecosystem and have heard that the main hurdles for climate founders are fundraising and hiring. We founded the workonclimate.org community to assist climate companies hiring technical talent, and I am very excited about the potential of Diamond List as a means of equalizing fundraising.
