Isometric is the agentic certification platform for the industrial economy. Its AI agents work alongside human verifiers, reviewing every data point so expert judgment is freed for the calls that matter, in place of the slow, manual reviews that have defined certification for decades. What used to take months now takes hours. From carbon removal and superpollutant reduction to low-carbon energy, fuels, and materials, Isometric brings them all onto a single platform, held to a single standard, with every certificate published on a single public Registry. Isometric is the largest certifier of carbon removal by contracted volume, trusted by Microsoft, Anglo American, JPMorganChase, and Boeing, and fully accredited by ICVCM, ICROA, and CORSIA.

Ucaneo is building the backbone of the carbon economy. Carbon is one of the worlds most important industrial commodities. It is essential for fuels, chemicals, materials, and manufacturing. Today, this carbon comes primarily from fossil resources. Tomorrow, it wont. As economies decarbonize, traditional sources of carbon disappear while demand for carbon remains. At the same time, demand for durable carbon removal, sustainable fuels, resilient supply chains, and energy security continues to grow. This creates the need for entirely new carbon infrastructure. Ucaneo is building that infrastructure. Our electrochemical Direct Air Capture (DAC) technology removes CO₂ directly from ambient air and produces high-purity carbon for permanent storage and the production of sustainable fuels, chemicals, and materials. By combining low energy demand, high CO₂ purity, and renewable energy flexibility, Ucaneo enables carbon removal and sustainable carbon supply at industrial scale. Founded in Berlin in 2022, Ucaneo is deploying the next generation of industrial carbon removal infrastructure to power the future carbon economy.

Restoring the global CO₂ balance by developing a unique marine carbon removal method that delivers optimum scale and quality at an affordable price.

Vaulted is an emerging leader in permanent carbon removal. A biomass carbon removal and storage (BiCRs) solution, Vaulted delivers permanent, high quality carbon removal at scale through the geologic sequestration of carbon-filled organic waste. Vaulted’s approach is designed to be the lowest-cost, gigaton scale, permanent carbon removal. We sequester sludgy organic wastes (biosolids, manure, agricultural, food waste, paper sludge, etc.) that today are sent to a landfill, dumped into an ocean/river, land applied, or otherwise left to decompose, releasing GHGs into the atmosphere. Vaulted leverages a suite of patented, mature, geologic slurry sequestration technologies which allow us to sequester organic waste with minimal processing. We inject deep under the earth’s surface, where the carbon is permanently trapped under a layer of impermeable rock - the same formations that have kept hydrocarbons underground for millions of years. We have two permitted, operational, facilities allowing us to reach near-term meaningful scale. Our carbon removal approach goes beyond vaulting carbon. It inherently improves local environmental and human health. In doing so, our operations redress historically unjust waste management practices and advance environmental justice. Vaulted is backed by leading carbon removal and climate investors, including Lowercarbon Capital, Earthshot Ventures, and WovenEarth Ventures.

We turn carbon emissions into natural carbon-negative textiles. Rubi is building a future where human prosperity and economic growth are planet-positive. We're unlocking CO2 as a natural resource for making critical materials, cost competitively, with our cell-free enzyme flow biocatalysis platform. We're producing carbon-negative textiles for the fashion industry as our first application. We make the same textiles apparel brands already use today, for half the cost of cotton at scale, and completely carbon-negative and water- and land-neutral. Our company is built on high-quality science, a focus on impact, honesty & transparency, and a sense of purpose in everything we do. We're backed by leading investors including Talis Capital, Plug and Play, Incite.org, Necessary Ventures, and Climactic VC.

Our vision is for a future in which the essential services that support our societies - water, energy, food - are affordable, safe, and accessible for everyone, everywhere. By leveraging AI to continuously learn from ever-changing patterns, we empower people with actionable knowledge for effective decision-making. While the digital revolution is creating the world of today, Emagin is building the architecture of the future, using the latest advances in artificial intelligence to repurpose information to sustainably manage humanity’s impact on the world. Emagin is now part of Innovyze, the global leader in water infrastructure data analytics with design, modeling, asset management and operational analytics software. We are accelerating widespread adoption of AI to transform the water industry at global enterprise scale. The idea was simple - use collected data to predict and optimize utility operations. As the team grew, so too did the idea and scope. Today Emagin’s technology uses cutting edge proprietary artificial intelligence for water utilities, food & beverage, paper, oil and gas facilities globally. Within the first two years, Emagin broke new ground through a framework agreement with the UK’s United Utilities and secured the largest deployment of AI technology in the region and first of its kind in the industry. In emerging markets, Emagin has been working with utilities to support technological leapfrogging, and has successfully deployed AI in non-digitized utilities. In established markets, Emagin has supported progressing facilities beyond digitization by implementing AI to fully optimize operations and save on expenditure. After winning a series of awards locally, Emagin was recognized in the international water sector by BlueTech and Global Water Intelligence. We look forward to continuing to build the future of smart cities, beyond digitization, and provide actionable intelligence to decision-makers.
