Gigaton

Self-learning process-control software for energy-intensive plants

Overview

Gigaton builds self-learning process-control software for energy-intensive plants in cement, steel, glass and chemicals. The system sits inside existing plant infrastructure and uses simulations and predictive models to test decisions before applying them to real equipment like fuel mix, kiln speed and oxygen levels. It also explains actions to operators and retrains on live plant data to improve over time. Unlike many AI tools, Gigaton’s platform continuously learns from live plant operation and provides transparent reasoning for its recommendations. It targets large sectors that contribute a big share of global greenhouse-gas emissions and is backed by academic origins, established investors, and a dedicated industrial-scale focus. The company aims to scale autonomous industrial control to cut emissions from major energy-intensive industries by optimizing operating decisions and keeping humans in the loop through explanations.

Simplify's Take

What believers are saying

  • June 2026 Series A added $26 million and lifted total funding above $35 million.
  • Management says current deployments save $1 million to $3 million annually per plant.
  • The team plans a fivefold headcount increase and expansion into steel, glass, and chemicals.

What critics are saying

  • Gigaton's customers are concentrated in cement, exposing revenue to one hard-decarbonize industry.
  • Autonomous control software faces plant-safety scrutiny; one bad optimization can halt production.
  • If operators reject closed-loop AI after a major incident, Gigaton's core category disappears.

What makes Gigaton unique

  • Gigaton sits inside plant controls, not dashboards, and adjusts kiln operations autonomously.
  • The company claims deployment in eight weeks at Mannok, Adani Cement, Heidelberg Materials, and Holcim.
  • Cambridge and UCL lineage plus Plural's June 2026 backing strengthen technical credibility.

Gigaton, alcemy, and CemAI publish white paper on AI's role across the cement production chain.

Gigaton, alcemy, and CemAI publish white paper on AI's role across the cement production chain. Gigaton, alcemy, and CemAI - Cement Intelligence, in partnership with World Cement, have released a new white paper titled "From quarry to lorry: how AI is solving cement's biggest production challenges." The guide brings together three companies operating across the cement and concrete production value chain to offer a practical, end-to-end roadmap for AI adoption. It covers the key prerequisites for successful deployment, including clean and connected data, domain expertise, and on-site leadership, alongside dedicated sections on predictive quality management, plant process optimisation, predictive maintenance, and driving long-term company-wide adoption. The white paper draws on real deployments with major producers and is aimed at plant managers, process engineers, quality specialists, and digital transformation leaders looking to move from AI ambition to measurable results. The release comes as Gigaton - formerly Carbon Re - announced a US$26 million Series A funding round, with deployments at Adani Cement, Heidelberg Materials, and Holcim already delivering over US$1 million in annual savings per plant.

Going Green: European Greentech Overview | November 2022 | Powered By Net Zero Insights

GreenTech is one of the biggest growth areas in the innovation and startup space, on a global level. It’s a market area that has the potential to shape and influence our future for the better, and investors and entrepreneurs are actively promoting development in this space. This report, powered by Net Zero Insights, aims to give an overview of everything that happened in GreenTech across Europe in the past month.GreenTech refers ​​to the use of tech that has a positive environmental impact at its core. It refers to those companies that are founded for a wider purpose – it could be reducing carbon emissions, tackling pollution, minimizing waste, protecting the world’s ecosystems or anything that contributes to making life on earth more sustainable and less harmful.This month, we noticed a slowdown in terms of funding after October’s GreenTech gold rush. It’s not to say there haven’t been exciting updates and developments, but there is certainly a noticeable decrease in funding amounts – approximately 67%! This month, some things did stay the same with EVs and the energy transition picking up most of the cash.In total, European startups in the climate and GreenTech space raised just over €1 billion in November – down from over €5.2 billion in October. France, Germany and the UK were the powerhouses of the continent, taking up 78% of the continent’s funding
