“The world’s first trillionaire will be a green-tech entrepreneur,” predicted Kara Swisher in the New York Times. Yes, that’s trillionaire, with a T.
Here are 30 inspiring moonshots from women entrepreneurs who are designing for a climate-positive future — improving energy storage, grids, food, sustainable materials, and more. Investors are betting big on climate innovation. “The world’s richest person should be somebody that’s fixing or fighting climate change,” said billionaire VC Chamath Palihapitiya.
1 — Dr. Etosha Cave, Dr. Kendra Kuhl (Co-Founders, Twelve)
“It’s a golden time if you really want to be an entrepreneur of any gender, but especially so for women compared to in the past,” said Dr. Etosha Cave, Chief Scientific Officer at Twelve, leading carbon transformation for a climate positive world.
The clean energy startup’s breakthrough technology eliminates emissions, by recycling carbon dioxide and water into higher-valued products such as jet fuel, using metal catalysts, and electricity. She credits funding, programming, and networking opportunities with support from a CalSeed program as critical enablers for her company.
Twelve co-founders transformed their lab discoveries into a commercial solution for making the world’s most critical chemicals from air (CO2), not fossil fuel. Twelve is currently taking pre-orders for its industrial-scale carbon transformation module.
Twelve CTO and co-founder Dr. Kendra Kuhl developed a reactor to turn carbon dioxide into useful chemicals. “We could see global warming happening,“ she said about her childhood in rural Montana watching the namesake ice formations of nearby Glacier National Park shrink. It inspired her to go into cleantech.
Headquartered in Berkeley, Twelve raised $57 million in Series A funding this year.
2 —Alexandra Rasch Castillo (CEO & Founder, Caban Systems)
CEO Alexandra Rasch Castillo is passionate about sustainability, energy access, and helping the most remote communities reap the benefits of greater connection and communication.
Her company Caban Systems designs and manufactures lithium-ion energy storage systems for backup and off-grid telecom applications, to reduce customers’ energy expenses (cell sites, fixed network and fiber optic sites) with a system that is longer lasting, more cost-effective, requires little to no maintenance, and can be monitored remotely. Focused on the telecom world, Alex explains how she came to green the 5G:
Having grown up in a developing country, a lot of the infrastructure that’s still used still has a lot of fossil fuels. I was at a dinner party in Mexico City and quickly realized in a conversation that we were having that a lot of the infrastructure that’s still there uses fossil fuel. Immediately, I thought, “Any infrastructure that uses fuel, if it’s a business opportunity, it’s an opportunity to remove and improve the conditions of the infrastructure.” With the mix of my background in battery design and commercialization of products, that’s how Caban was born.
Headquartered in Burlingame with offices in Puerto Rico, Mexico and Guatemala, Caban Systems raised $35 million in funding this year.
3 — Astrid Atkinson (CEO & Co-Founder, Camus Energy)
Infrastructure expert Astrid Atkinson spent over a decade in engineering leadership at Google. After leaving the company, she dreamed of zero carbon grid orchestration and founded Camus Energy.

7 — Kimberlie Le (CEO & Co-Founder, Prime Roots)
Prime Roots CEO Kimberlie Le is no stranger to the restaurant and food industry. She grew up eating koji, which is “now highly beloved by Michelin-starred chefs, but part of my culinary toolkit — we started fermenting koji when I was young,” she told Berkeleyside:
“Koji is itself a beautiful, naturally-textured, high-protein food — you can use it as a base for all types of meats and seafoods. We are using our fungi superprotein as the base of our delicious high protein products that are good for you and our shared planet. Our roots start at UC Berkeley in the Alternative Meat Lab program [at UC Berkeley’s Sutardja Center for Entrepreneurship and Technology] as well as IndieBio.”
Eating meat contributes to greenhouse emissions (not to mention cholesterol-related health problems). Prime Roots makes plant-based whole foods and ready-to-eat meals for the future-forward set. You can find Prime Roots products online, and in markets like Whole Foods and Berkeley Bowl. Look for the plant-based bacon, signature meals, and community.
Headquartered in Berkeley, Prime Roots has raised over $18 million in funding to date.
8 — Dr. Lisa Dyson (CEO & Founder, Air Protein)
CEO Dr. Lisa Dyson is reinventing how food is produced in order to sustainably feed 10 billion people by 2050. Her company Air Protein is pioneering a new category of food production — air-based protein — a solution to feed the growing population without the strain on natural resources. She explains:
“We’re doing a kind of reverse fermentation you can call it or air-based fermentation. The fact that we’re doing that and we don’t require any arable land for our protein, and we don’t require sugar or any of those other kinds of inputs, means that we use significantly less land versus the alternatives. Of course, along with that comes significantly less water. And so in essence, what we have is the most sustainable way to make protein and then that allows us to make ultra-sustainable meat. And we’re focused not just on sustainability, although that’s why we built the company, but we’re also focused on nutrition and delivering nutrients to consumers, as well.
Headquartered in Berkeley, Air Protein raised over $32 million in Series A funding this year.

CEO Nuha Siddiqui co-founded Erthos with Chang Dong (CTO) and Kritika Tyagi (Head of Product) to make plant-powered plastics the natural choice over single-use plastics. “Eco-friendly plastics have evolved over decades. We spent a lot of time making sure that our solutions were compatible with the existing infrastructure,” she said.“It’s funny because startups usually want to find a way to disrupt the industry, but we took a bit of a different approach. We tried to disrupt the industry as little as possible and make sure that it was compatible with the infrastructure that we’ve spent decades building. So, compatibility and compostability were our two main challenges and also key features that we needed to make sure we embedded in our material.”
With operations in Mississauga and Shenzhen, Erthos has raised $7.3 million in funding to date.
