About Third Derivative
Global ecosystem, curated connections, built for impact.
We connect climate tech innovators with a deep network of experts and investors to achieve a brighter, more equitable climate future.
Why do climate tech entrepreneurs in some parts of the world get the funding, access, and resources it takes to bring great ideas to market, while others get neither the help nor the recognition they deserve?
Because funding and access are based on who you know, and what they know.
At Third Derivative (D3), we know we can only achieve the rapid, massive tech scaling needed to address climate change by giving more breakthrough thinkers a chance to participate and prosper.
By guiding and supporting climate tech entrepreneurs bringing new ideas and innovation to market, we are accelerating the clean future worldwide. Through a vast global network of deep experts, corporate partners, and investors, we help startups go to market faster with their world-changing ideas, create real impact, and transform markets.
A sustainable, prosperous, equitable climate future.
To build an inclusive, global ecosystem that rapidly finds, funds, and scales climate tech innovation and transforms markets.
Committed partners championing the world’s most promising climate tech startups.
Founded by RMI and New Energy Nexus, Third Derivative (D3) is accelerating the rate of climate innovation through our inclusive ecosystem approach, which rapidly finds, funds, and scales climate tech globally. We launched in December 2020 with 47 companies, the largest cohort of climate tech companies in the world.
By uniting and aligning committed investors, large corporates, and market and policy experts with the world’s most promising climate tech startups, D3 bridges finance and resource gaps to increase speed to market. Our flexible and highly curated accelerator program enables startups to focus on their unique needs and opportunities.
Today D3’s collaborative ecosystem includes $4T market cap of corporate partners, $7B AUM of investor partners (across five continents), and over 100 startups addressing climate challenges across all major emissions sectors. Together, we are moving markets to achieve a brighter, more equitable climate future.
Meet Our Team
Entrepreneurial trailblazers. Cleantech VC pioneers. Communications mavens.
Our dedicated climate ecosystem leaders each bring distinctive expertise to the table—yet all share the conviction that we must bring together innovation, expertise, and an inclusive ecosystem approach to solve the climate crisis.
We embrace complexity—including hard science and hard tech—or undertaking deep diligence on tough-to-understand, under-hyped solutions often overlooked by many investors and accelerators.
With a growing global team spread across three continents, D3 experts work collaboratively with teams concentrated in Colorado, California, and New York, and other core members stationed in South Africa, India, and Singapore.
