Converge’s $22M Boost to Decarbonize Concrete with AI

On May 23, 2025, London-based cleantech firm Converge secured $22 million in a funding round to scale its AI-driven platform, ConcreteDNA, aimed at slashing carbon emissions in concrete production. Cement, a key concrete ingredient, accounts for 8% of global CO2 emissions, releasing 900 kg of CO2 per 1,000 kg produced. With concrete as the world’s most-used material—30 billion tonnes annually—this investment could reshape a notoriously hard-to-decarbonize industry. Led by ABN AMRO’s Sustainable Impact Fund, the round signals strong market faith in Converge’s tech. But can AI truly transform an industry rooted in tradition?

How Converge’s Tech Works?

Founded in 2014, Converge uses AI, proprietary sensors, and real-time data to optimize concrete production and use. Its ConcreteDNA platform integrates three core functions:

• AI-Powered Predictive Models: These forecast concrete performance, allowing precise mix designs that cut cement use by up to 15%, reducing emissions without compromising strength.

• Sensor-Based Monitoring: Embedded sensors track curing in real-time, detecting inefficiencies early and minimizing waste—20% of concrete is typically overused due to conservative designs.

• Data Management: The platform analyzes site conditions, weather, and material properties, optimizing pours and slashing CO2 by 100-200 kg per cubic meter, per Converge’s data.

This tech tackles cement’s carbon intensity head-on. Producing one tonne of cement requires 3.5 GJ of energy and emits 0.9 tonnes of CO2, largely from clinker production. By fine-tuning mixes and reducing overpour, Converge claims 10-20% emission cuts per project, alongside 5-10% cost savings.

“We’re tackling one of the hardest sectors to decarbonize,” said CEO Raphael Scheps. “This funding lets us scale AI models globally to optimize materials and drive down emissions.”

Why It Matters?

Concrete’s environmental toll is staggering. The industry emits 4.4 billion tonnes of CO2 annually, more than aviation and shipping combined. With global construction set to grow 35% by 2030, driven by urbanization in Asia and Africa, decarbonizing concrete is critical to hitting 1.5°C climate targets. Converge’s tech aligns with global efforts like the EU’s $1.1 billion hydrogen push or JPMorgan’s $90 million CO2 removal deal, reflecting a broader shift toward innovative climate solutions.

The platform also boosts efficiency. Construction firms lose $1.6 trillion yearly to waste and delays, per McKinsey. ConcreteDNA’s real-time insights cut material overuse and speed up projects, saving $50,000-$200,000 per mid-sized build. Early adopters like Mace and Laing O’Rourke report 12% emission reductions on UK projects, with 98% accuracy in strength predictions.

The Investment and Its Backers

The $22 million round, led by ABN AMRO’s Sustainable Impact Fund, included Climate Investment, TO Ventures, Force Over Mass Capital, Move Energy, PI Impact, and J-Impact. This follows a $15 million round in 2022, bringing Converge’s total funding to $45 million. The capital will fund global expansion, starting with Europe and North America, and enhance generative AI to design low-carbon mixes using alternative materials like fly ash or slag.

“Converge is driving efficiency and lower emissions in a high-impact industry,” said Gaetano Giuffrè of ABN AMRO. “We’re excited to back their growth.”

The investor mix reflects confidence in cleantech. ABN AMRO’s fund, managing €1 billion, targets scalable green tech, while Climate Investment, backed by OGCI, focuses on heavy industry. Move Energy’s hydrogen expertise hints at future synergies, as green hydrogen could power cement kilns, cutting emissions 30%.

Challenges Ahead

Decarbonizing concrete isn’t easy. Cement’s chemical process—heating limestone to 1,450°C—produces 60% of its emissions, untouchable by AI alone. Converge’s tech optimizes mixes but doesn’t address clinker production or scope 3 emissions from supply chains, which are 20% of the total. Scaling globally faces hurdles: 70% of cement is produced in China and India, where low-cost coal-fired plants dominate, and regulatory push for low-carbon concrete is weak.

Adoption is another barrier. Construction is conservative—80% of firms stick to traditional methods, per Deloitte. Converge’s sensors, costing $500-$1,000 per site, require upfront investment, and training workers takes time. Competition is stiff, too, with firms like CarbonCure injecting CO2 into concrete to cut emissions 5-10%, and Holcim testing carbon-neutral cements.

Policy risks loom. The EU’s 2023 Carbon Border Adjustment Mechanism pushes green concrete, but U.S. rollbacks under Trump’s 2025 agenda could stall progress, with 15% of global cement markets lacking carbon pricing.

What’s Next?

Converge plans to deploy ConcreteDNA on 500 projects by 2027, targeting 1 million tonnes of CO2 savings—equivalent to removing 200,000 cars yearly. Partnerships with giants like Heidelberg Materials, who aim for 50% emission cuts by 2030, could accelerate adoption. The firm is also exploring AI to integrate geopolymers, cutting cement use 70%, though scalability lags due to supply constraints.

Globally, the low-carbon concrete market, valued at $27 billion in 2024, could hit $60 billion by 2030, per MarketsandMarkets. Converge’s tech could capture 5% of this, especially in Europe, where 90% of new builds face ESG mandates. Pennsylvania’s Lightning Plan and the U.S. Air Force’s multi-fuel tech show parallel innovation, but concrete’s scale dwarfs them. If Converge cracks Asia, where 60% of cement is used, the impact could be seismic.

“This is about rewriting how we build,” Scheps said. “AI can make concrete sustainable without reinventing the wheel.”

With construction emissions rising 2% yearly, Converge’s $22 million is a bet on tech-driven change. Success hinges on adoption, policy support, and proving AI can outpace traditional barriers. Will it redefine the industry, or remain a niche fix in a carbon-heavy world?
