Climate Startups funded by Y Combinator (YC) in the San Francisco Bay Area 2024

EARTH AI is a predictive explorer and driller for critical metal deposits. We discovered 5% of the world’s deposits this year, thanks to our AI with 66% vs 0.5% success rate and Low Disturbance Drilling tech which enables 1/4 cheaper and 4X faster site testing.

Pachama is a leading climate-tech company harnessing cutting-edge technologies such as computer vision and satellites to drive funding to effective reforestation and conservation projects that sequester carbon, enhance biodiversity and enrich local communities around the world. Through a tech-verified marketplace that counts as customer the likes of Amazon, Airbnb, Netflix and Nespresso, the company drives capital to forests in Brazil, Mexico, India, the USA and beyond. The company is backed by top investors such as Bill Gates' BEV, Chis Sacca's LowerCarbon, Amazon Climate Pledge among others. The company is fully remote and driven by a strong sense of purpose.

Noya is radically reducing the upfront capital costs and installation time required to perform direct air capture. We're doing this by retrofitting existing pieces of industrial equipment like cooling towers and turning them into CO2 capture machines.

We design, develop and manufacture sustainable battery solutions.

With Wren, anyone can offset their carbon footprint by supporting credible nature, industry, and policy projects. We also show users how they can reduce their carbon footprint. We make it easy for anyone to turn climate confusion into climate action.

Ferveret develops liquid cooling solutions inspired by nuclear power plant cooling. We save data centers 96% in cooling costs, 68% on capital costs, and reduce their carbon footprint by 40% while increasing chip performance by 2X. Today, about 40% of the electricity used in these facilities is wasted on cooling. Our technology eliminates this wasted energy.

AirMyne is building machines to capture & remove carbon dioxide from ambient atmospheric air so it can be utilized or sequestered downstream. Our team is based in Berkeley, CA.

Alga Biosciences is a fast-moving startup focused on transforming the agricultural industry. Our mission is to make an immediate, dramatic impact on global methane emissions produced by enteric fermentation in partnership with the cattle industry. We believe in leveraging biology to tackle the world’s biggest problems.

Holy Grail removes carbon dioxide from the atmosphere to contribute to the long-term sustainability of humans and other species on Earth

Maple Materials, Inc. (Richmond, California) develops a low-cost electrolysis process to split carbon dioxide into graphite and oxygen. Due to several unique features of our production process and product, we have potential to produce battery-grade graphite anode material one-third the cost of current graphite anode materials. When powered by renewables, this process has the potential to be carbon negative.

Boundary Layer Technologies is building the next generation of water mobility, starting with a ultra-performances electric foiling water craft called Valo. Valo flies 2ft above the water at 58mph, in silence, with no waves or emissions, and will be the most exhilarating thing on the water.

Today, water supplies are more scarce than ever before, requiring water utilities to operate more efficiently than anyone thought possible. That’s where we come in. Like water, the flow of data from water utilities is both measurable and manageable. Valor helps utilities transform complicated data into simple solutions that can make a big difference. Some call it advanced water utility analytics. We call it all in a day’s work.
