At Funga, we use the forest fungal microbiome to improve forestry outcomes and address the climate crisis while enhancing beneficial microbial biodiversity. We combine modern DNA sequencing and machine learning technology with breakthrough research on the forest microbiome to put the right native, biodiverse communities of mycorrhizal fungi in the right place. This leads to more quality wood created more quickly, more carbon sequestered, and more resilient forest ecologies.

Charm Industrial is working to return the atmosphere to 280 ppm CO₂. We design, build and operate a fleet of mobile fast pyrolyzers that convert ag and forest biomass residues into bio-oil for use in carbon removal and direct-reduced-iron steelmaking.
In 2020 our Chief Scientist and co-founder Shaun Meehan had two breakthroughs (bio-oil intermediate and bio-oil sequestration) that kickstarted the company. Within 10 months we completed our first carbon removal injection and in 2021 we completed more than 5,000 tons of CO₂e removal for customers like Stripe, Shopify and Microsoft.

Sublime is developing a breakthrough process to make low-carbon cement. The technology replaces the industrys legacy fossil-fuel-intensive thermal calciner process with an electrochemical process that produces low-carbon cement at ambient temperatures with renewable electricity. Sublime was started in 2020, as a spin-out of Yet-Ming Chiangs lab at MIT (Form Energy, A123, American Superconductor, 24M, Desktop Metals).

Gradient’s mission is to cool the world by transforming every home to be more comfortable and healthy for the people who inhabit it — without compromising the environment. Today, heating and cooling equipment emits more greenhouse gas emissions than the entire transportation sector, and expansion in the use of cooling is projected to double these emissions in the next 30 years. However, comfortable buildings are critical for health and productivity, especially among communities that are vulnerable to the effects of climate change. Gradient’s vision is a future where everyone has access to comfortable buildings that are fully decarbonized. Our flagship product is a high-efficiency and low-carbon window heat pump suited for moderate climates; our second-generation window heat pump, the All-Weather 120V, is suited for cold climates.

The MicroByre team makes pets out of bacteria. The vast majority of prokaryotes on the planet are not currently considered cultivable, let alone genetically modifiable. MicroByre domesticates and then genetically engineers otherwise reluctant, recalcitrant, and rebellious bacteria. We get them to eat out of our hands.
With friends like these, who needs petroleum? Newly cooperative bacteria will help us replace ancient biomass (petrochemicals) with renewable biomass (lawn clippings) efficiently and economically.
This isn’t the synthetic biology you’ve read about. We don’t do Escherichia coli and we don’t do Saccharomyces cerevisiae. We don’t do gene circuits and we don’t do heterologous expression. We engineer naturally cool but standoffish bacteria to be cooperative, and thus even cooler.
Diversity is strength. We take a lesson from the study of ecology: it takes a lot of different kinds of skills working together with mutual respect to make a dent in the world. We are committed to a maintaining a work environment free of harassment and discrimination. All recruitment, salary, & promotion decisions are based on business need, qualification, and job requirements with no regard to race, ethnicity, gender, sexual orientation, family or parental status, veteran or disability status, religion or belief, or age.

C-Motives mission is to create electric machines that directly lead to reduced carbon emissions through higher efficiency renewable generators applicable to the next generation of e-mobility vehicles and more efficient industrial torque motors. C-Motives unmatched torque, efficiency, and simplicity will lead to a new generation of applications that create more renewable power and waste less electricity.
C-Motives motors run on the principle of electrostatic forces, also known as "static cling," and stands to change the machines that shape and run our lives. Our motors produce torque by the same principle of rubbing a balloon on a head of hair. And just like hair doesnt heat up with the balloon, our motors produce torque with nearly zero loss, versus using copper coils wound around steel with rare earth permanent magnets.
