Addis Energy is scaling a new ammonia production pathway that revolutionizes the century-old chemical production process. By targeting iron-rich resources in the subsurface, Addis is forging a new method for chemical synthesis: injecting engineered fluids that harness the chemical & thermal potential of the earth to produce clean ammonia. This transforms ammonia synthesis into a net energy positive process without any CO2 emissions and enables producing ammonia cheaper than traditional methods.

Rock Zero is reinventing hardrock lithium refining. Our proprietary chemical technology lowers the cost and environmental impact of converting lithium-bearing minerals into battery-grade chemicals. Rock Zero spun out of renowned MIT professor and cleantech entrepreneur Yet-Ming Chiang’s Lab in 2024. It is backed by leading VCs and federal funding agencies, including ARPA-E and a Fortune 100 automotive company.

Were hiring! Pascal is a technology company commercializing solid refrigerant heat pumps and air conditioners. The HVAC sector currently accounts for 40% of global energy usage while also directly emitting 2 Gton CO2 eq. of greenhouse gas refrigerants to the atmosphere. Pascal’s solid refrigerants undergo solid–solid phase transitions in response to pressure, and can operate within the same pressure and temperature ranges as standard gas refrigerants. Pascal’s technology eliminates the direct emission of refrigerants to the atmosphere, and offers a pathway to more efficient, more sustainable, and cheaper heating and cooling systems.

Osmoses is a membrane start-up aiming to transform industrial chemical separations with innovative molecular filters.

Make weather-related decisions in time to matter. Reliable, award-winning 2- to 52-week forecasts for adapting to a more volatile climate.

We develop scalable quantum computers to tackle the world’s hardest computational challenges. Join us: https://jobs.polymer.co/atlantic-quantum.

Common Sense Machines is training artificial intelligence that learns to translate the visual world into a 3D simulation for people and machines. 3D simulations have great value; we build 3D models to create photorealistic images of products and spaces at a fraction of the cost of photography, develop diverse assets for game and augmented realities, use CAD to prototype and print new parts, or create synthetic worlds to test and train autonomous systems. But 3D models are still too slow, hard, and expensive to create. Common Sense Machines is building a Real-to-Sim platform for creating build human-like 3D models with machine-like speed and scale. Common Sense Machines was founded by a group of PhDs and faculty from MIT. We have worked on large AI systems at DeepMind and have collectively founded three companies with successful exits. The company is based in Cambridge, MA. We are venture-backed and looking to expand our team of scientists and engineers.

Biobot Analytics develops cutting-edge technology to transform sewers into public health observatories. Wastewater contains valuable information about the health of communities. We collect it. We analyze it. We tell you how to leverage it to make your city better. Our first product is to measure opioids and other drug metabolites in sewage to estimate consumption in cities. With this data, those working on harm reduction can assess the scope of the epidemic, allocate resources, and gauge the effectiveness of programming over time.

Volta Labs is a group of antidisciplinary scientists and builders working at the intersection of engineering and biology. We are building a sequencing technology agnostic platform that spans from the raw biological sample to sequenceable molecules. We are doing this by reinventing the full stack — hardware, software, chemistry, and biology — to create simple, flexible, and powerful solutions for sample preparation and beyond.

Our all-natural protective layer slows down the spoiling process of fruit, veggies, meats, and seafood to help you enjoy fresher food for longer.

Goodpath is a new approach to health. It is simple, personalized care for common conditions with proven results. Patients finally have access to robust, integrative healthcare that is coach-supported and evolves with them. Better than conventional care - this is care done differently.  Founded by veteran entrepreneurs Bill Gianoukos and Carl Nehme, and Harvard-trained physician Dr. Akl Fahed, Goodpath provides unique solutions to complicated health problems.
