Electra

Series B in 2025
Electra is a company dedicated to revolutionizing iron and steel production by significantly reducing carbon dioxide emissions. It specializes in alternative steelmaking technology that employs innovative electrochemical and hydrometallurgical processes. By electrifying and decarbonizing the steelmaking process, Electra enables the production of low-carbon clean iron from various ores and renewable energy sources. This approach not only minimizes the environmental impact associated with traditional steel production but also helps companies lower energy intensity and costs, promoting sustainability within the industry.

Arca Climate Technologies

Seed Round in 2024
Arca is a leading carbon dioxide removal (CDR) company. Arca accelerates natural process of carbon mineralization, by reacting atmospheric carbon dioxide with ultramafic mine tailings rich in magnesium silicate minerals, such as serpentine and brucite. By leveraging partnerships with mining companies, Arca transforms mine waste into a carbon sink, permanently storing CO₂ as stable carbonate minerals. The company is at the forefront of scaling carbon dioxide removal (CDR) solutions by integrating geochemical expertise, real-time monitoring, and verification methodologies. Arca collaborates with major buyers of carbon removal credits, such as Shopify, Stripe, Watershed and MaRS, and has established formal methodologies for recognizing and quantifying mineralization in voluntary and compliance carbon markets.

GenoMines

Seed Round in 2021
GenoMines is a company focused on sustainable mining through innovative biological methods. It specializes in using plant-based technologies to extract critical metals from soils that are below traditional cut-off grades. By genetically enhancing hyperaccumulator plants, GenoMines leverages nature's ability to absorb metals, thereby not only sustainably mining these resources but also depolluting soils and increasing the availability of agricultural sites. This approach addresses significant environmental and societal challenges associated with conventional mining methods, aiming to support the transition to green energy in a responsible manner.

CarbonChain

Seed Round in 2020
CarbonChain is a developer of a carbon accounting platform designed to assist organizations in tracking, reporting, and reducing greenhouse gas emissions throughout their supply chains. The platform is particularly focused on high-emission industries such as metals, mining, agriculture, and manufacturing. By enabling companies to identify their emissions-related transactions, CarbonChain helps them take proactive measures to mitigate their environmental impact and adapt to increasing carbon prices. This capability not only aids firms in understanding the climate implications of their procurement choices but also supports their transition towards a net-zero economy.
