LoamBio is an agricultural tech company whose technology harnesses the power of microbes, specifically endophytic fungi, to create seed coatings which improve soil health and sequester carbon, which support greater crop yields, and potential income for farmers through carbon markets.. These coatings, applied during planting, boost the natural ability of plants to store carbon in the soil and promote their growth and resilience against environmental stressors like drought, disease, and high temperatures. Loam positions itself as a farmer-centric company offering programs like SecondCrop, which helps farmers earn additional income through carbon credits for the carbon sequestered in their soil, and CarbonBuilder, to enable farmers to integrate soil health analytics seamlessly with existing practices.

Olio a free app to reduce household and food waste by fostering a hyper-local sharing economy. People can list unwanted but usable items, including surplus food, as well as clothes, books, and furniture. Neighbors can browse listings and arrange free pickup, giving unwanted items a second life and saving it from landfills. This approach combats waste, promotes sustainability, and fosters a sense of community by encouraging people to share and connect with those around them. Because it diverts far more greenhouse gasses across the 49 countries it operates in than it produces, Olio is a carbon-negative company.

Pol.is is an open source platform that facilitates group decision-making by allowing large numbers of people to share ideas and opinions on a topic. Polis' real-time system gathers the contributions of large groups, and then leverages advanced statistics and machine learning algorithms to analyze the collective input and surface points of consensus and where areas of dissent occur. Unlike some social media platforms, Pol.is aims to encourage constructive dialogue and bridge-building rather than amplify existing divides. Pol.is helps groups identify common ground and reach collaborative solutions in areas like policy development, market research, and community planning. As an open-source tool available to all, Polis is already adopted by various groups including governments, academics, independent media outlets, and everyday citizens. Anyone can access, modify, and contribute to the Pol.is code base, ensuring transparency and fostering continuous development.

Regrow Ag's Agriculture Resilience Platform is a software program that helps stakeholders across the agricultural supply chain measure and improve their environmental impact and identify areas where adopting regenerative practices would be most beneficial. They use a combination of agronomic insights, satellite imagery, and scientifically validated crop and soil models to monitor and verify the implementation of these practices, enable auditability and transparency in value chains. Regrow serves more than 100 organizations who have collectively invested more than $19M to help farmers adopt regenerative practices. These actions will abate more than 600k tonnes of CO2e, equivalent to the carbon sequestered by 713k acres of U.S. forests in one year. The platform also aggregates agricultural systems data worldwide to garner new insights about resilient farming and expand practice adoption, and to support stakeholders like governments and academic institutions to inform agricultural policy, advance academic research, and implement innovative farm projects that expand the adoption of resilient practices.
