Industry: Artificial Intelligence

Shoreditch-based start-up Polaron, founded in 2023 by Isaac Squires, Steve Kench and Sam Cooper, has developed a state-of-the-art generative AI model that explores thousands of material designs in under a day – a task that takes current simulations 50 years.

Spinning out their research at Imperial College London, Polaron can improve battery energy density by 10% – equivalent to adding 20 miles of range to an electric vehicle (EV).

The start-up leverages microstructural image data to bridge the gap between the way materials are made and their performance. The technology empowers engineers to characterise materials, quantify microstructural variation, and optimise microstructural designs faster than ever before.

Secretary of State for Science, Innovation and Technology, Peter Kyle, said of the start-up: “Polaron exemplifies the promise of AI.”

The company’s vision is to harness the power of AI to accelerate the development of the materials that are critical to a sustainable future.

The Compliance Principles for Disruptive Entrepreneurial Success

Most founders treat compliance as something to deal with later. In reality, poor compliance — not regulation itself — is what slows companies down. When embedded early and treated as a strategic asset, compliance becomes a powerful growth engine rather than a brake on innovation.
