D3 Announces Its First Cohort of 2023

Our most selective cohort so far spans five countries and new technology categories for D3.

We're thrilled to unveil the 15 climate tech startups in our first cohort of 2023 — our most selective cohort so far.

After a landmark year in 2022 for global momentum in climate commitments, legislation, and investments, Third Derivative (D3) is excited to start 2023 by welcoming 15 impactful startups to join our new Cohort 23-1.

This may constitute the smallest of D3’s cohorts to date, but the impact potential and technological innovation across the group far exceeds its size. We recognize these startups as the leading climate stewards of tomorrow, who are already poised to capitalize on current momentum in the space—and add to it with their groundbreaking solutions and world-class leadership teams.

Highlights from D3’s Latest Cohort

The 15 startups onboarded with Cohort 23-1 were selected from a pool of nearly 450 applicants, representing a <4% acceptance rate and proving D3’s most selective cohort to date. 

Like our other cohorts, this one continues to raise the bar on innovation, and brings the benefit of more diverse voices to the table. We are proud that two-thirds of the teams feature BIPOC executive leaders, and one-third have a female founder.

And because geographic diversity is critical to success, it’s also notable that Cohort 23-1 startups are headquartered across four continents and five countries, including Australia, Germany, India, Israel, and the United States. By bringing these initiatives into our ecosystem, we’re also deepening D3’s existing networks in these locations and around the world. 

As they begin the program, Cohort 23-1 has already raised a collective >$37.3M in external funding (both debt + equity), and created 314 rewarding climate jobs on their teams worldwide. With such impressive numbers right out of the gate, we can’t wait to see their impact climb throughout the next 18 months of D3’s program.

Lastly, the startups in this high-quality group were chosen for their uniquely promising approach to bringing down carbon emissions in longstanding sectors—as well as for breakthroughs in mitigating climate impact from newer markets. 

A few of the important themes they’re tackling include:

  • Carbon Markets Powering Solutions to New and (Very) Old Problems: Several cohort members are bringing fresh strategy to carbon credit use, from leveraging credits to finance carbon sequestration and developing a trustworthy carbon credit tracking system, to incentivizing climate-friendly building materials and helping households replace unhealthy wood and charcoal stoves with electric devices. 

  • Decarbonizing the Built Environment: Other startups in Cohort 23-1 turn their sights to the buildings consuming so much of our carbon footprint. Their solutions include a mix of low-carbon materials made with fiber-based organic materials, novel manufacturing processes, geothermal power for heating/cooling, and modeling software to find the most cost-effective climate-friendly building solutions.

  • Industry On The Mind: Considering many of the hardest-to-abate challenges fall in the industrial sector, we’re also excited that one-third of the cohort is tackling various challenges in battery chemistry and rare earth metal usage, as well as power electronics and electric motors, and biofuels made from the carbon byproducts of industrial processes.

Now, we proudly invite you to learn more about the individual startups themselves—which you can also explore on our portfolio page. 🚀
