Gigaton (formerly Carbon Re) has raised $26M in a Series A led by Plural to scale AI-powered autonomous control systems for cement, steel, glass, and chemicals plants.
Customers, including Adani Cement, Heidelberg Materials, Holcim, and Mannok Holdings, are already saving $1M–$3M annually per plant while cutting approximately 30,000 tonnes of CO₂ per year.
Funding will support a fivefold team expansion and entry into steel, glass, and chemicals manufacturing.
For decades, heavy industry has relied on control systems designed for a different era. Today, manufacturers face soaring energy costs, volatile fuel markets, tightening emissions regulations, and growing operational complexity, yet many cement plants, steel mills, and glass factories still run on software built decades ago, requiring constant human intervention to maintain efficiency. Meanwhile, China is accelerating toward fully autonomous “dark plants” capable of operating with minimal on-site oversight, widening the competitive gap for industrial producers elsewhere.
London-based Gigaton believes AI can help close it. The company has raised $26M in Series A funding led by Plural along with 2150, Semapa Next, Planet A Ventures, Cambridge Enterprise Ventures, UCL Technology Fund managed by AlbionVC with UCL Business, and Clean Growth Fund. The round brings total funding to more than $35M and will be used to grow headcount fivefold and expand beyond cement into steel, glass, and chemicals.
