Thola
Thola is helping decarbonize and optimize industrial buildings, with a focus on food and chemical manufacturing factories. Thola’s aim is to increase energy efficiency, cut maintenance costs, and reduce critical infrastructure downtime through real-time energy consumption monitoring and fault detection using smart sensors and thermal imaging cameras connected to Thola’s AI software—providing fault analysis and description using prescriptive AI to avert equipment malfunctions and reduce costly downtime. Thola is also building digital modeling features in their software using computer vision that will enable building owners to generate digital twins of their buildings and monitor them, as well as fault region segmentation from imagery generated from IR cameras to provide the exact locations of detected faults.
ADAPTA Inc.
ADAPTA develops climate risk management products for financial intermediaries. Its 1st MVP, the ADAPTA Climate Score (CS), was developed and tested over 24 months as proof of concept. The product has been rolled out in Kenya, and is planed to roll it out in East Africa, the US, and Mexico in 2024. CS leverages biodiversity, climate, soil, and water data. The CS is analogous to a credit score using past data to forecast future risk. It was developed in discussions with six banks and is being tested by three banks before going commercial in early 2024. ADAPTA is beginning to develop a new product, “the digital portfolio system,” which will provide lenders and borrowers with satellite imaging, weather, and NDVI data.
Treeva
Treeva provides energy systems that can efficiently harness renewable energy from the airflow of passing cars, trains, and natural wind whilst withstanding severe turbulent conditions. It transforms energy that is usually uselessly dissipated into the surroundings into a renewable source. The turbines use readily available land and passing transport to provide renewable power that is reliable, affordable, and efficient. At just 2 meters tall, Treeva turbines are installed alongside transport infrastructure and provide off-grid energy, powering essential infrastructure such as street lighting, safety systems, maintenance depots, or EV charging. The turbines have twice the energy efficiency of alternatives, from 12-17% to 34%. This results in a significant payback period, as well as providing predictable power based on the speed and frequency of trains or cars, for a reliable renewable energy source. Combining high efficiencies and reducing resource extraction, the turbines also save 3 times the carbon emissions as alternative vertical-axis wind turbines. Designed with recyclable, low-impact materials and reusing parts, Treeva turbines contribute to a waste-free world, and Treeva’s decentralized approach allows for localized energy generation, which reduces reliance on grid infrastructure in remote or urban areas.
Sotira
Sotira is an AI-powered workflow and compliance automation software for reverse logistics. Sotira leverages AI to enable companies to offload and monetize their surplus inventory.
CocoaFiber
CocoaFiber transforms the waste of the chocolate industry into high-performance, plant-based next generation materials. Every year, 100,000 tons of cocoa pod husks are discarded or burned, contributing to carbon emissions and lost income for farming communities. The textile industry, made up of 67% non-renewable polyester, contributes about 10% of global GHG emissions and 35% of microplastics accumulation in our oceans. CocoaFiber addresses this dual challenge by using a proprietary cellulose extraction process to create a biodegradable fiber that can be spun using existing textile infrastructure. Their material offers a renewable alternative to synthetic fibers like polyester and wood-pulp-based viscose, reducing microplastic pollution and deforestation impacts. By bridging agriculture and fashion, CocoaFiber creates new revenue streams for cocoa farmers, re-engages youth in agriculture through upskilling and technology, and drives forward a regenerative, circular economy model. CocoaFiber aims to center equity, climate innovation, and nature-based solutions in the global sustainable materials transition. Headquartered in Biella, Italy—a historic textile hub—CocoaFiber is building a supply chain that honors craftsmanship while pushing innovation forward. By transforming waste into value, CocoaFiber not only reduces environmental harm, but also positions smallholder farming communities as essential players in designing a more just and sustainable future.
Parsons Kinetics
Parsons Kinetics is transforming the future of wind energy through modular, bio-inspired solutions designed for distributed generation. Their flagship innovation, the Bioseed turbine, is engineered to perform efficiently in normal-speed winds, unlocking new possibilities for clean energy in areas previously deemed unsuitable for traditional wind power. By integrating advanced engineering with AI-driven site matching, Parsons Kinetics connects landowners, small farmers, and industries with the ability to generate their own renewable energy profitably. Their model empowers communities to diversify income, increase resilience against climate change, and actively participate in the global energy transition.
Parsons Kinetics is committed to making renewable energy accessible, scalable, and impactful. Their systems are designed for durability, easy installation, and low maintenance, ensuring long-term value for their partners. Through a growing network of local installers and impact-driven financing options, they are building a decentralized, inclusive energy future. With operations in the United States and Latin America and partnerships spanning corporate, agricultural, and mining sectors, Parsons Kinetics is positioned to lead the expansion of distributed wind generation worldwide—one community, one turbine at a time.
Map Collective
Map-Collective provides a software solution for corporate and government sustainability teams to discover supply chain transparency and automate sustainability metrics tracking and operational decision-making using AI. Map-Collective’s solution for resource transparency is revolutionary. They weave together data from bill of lading, IoT sensor networks, scientific databases, news articles, and more to create a multilateral information system that can assist companies not only in ESG goals, but also in their core business operations. Map-Collective values radical transparency and envisions a future where we can get down to the smallest building block we can map, the atom.
