Google-owned DeepMind has been responsible for some of the worlds biggest breakthroughs in machine learning but today more and more staffers are leaving the London-based firm to launch their own ventures as investment into AI explodes.

One of those is Jonathan Godwin, cofounder of London-based Orbital Materials, a startup using generative AI to create novel materials for applications like carbon capture and sustainable aviation fuel.

He tells Sifted that he needed to leave the security and structure of DeepMind if he wanted to be able to focus on using AI to create solutions for the climate crisis.

I felt like you needed a company really focused on that ambitious goal and not just focused on AI and so it needed to be something different from what we were doing at DeepMind, he tells Sifted.

Orbital Materials is one of a growing number of companies that are training AI models on raw scientific information (others include Duisburg-based Hortiya and Cambridge-based BeyondMath), as opposed to the vast troves of human language that language models like ChatGPT are trained on.

In Orbitals case, it involves feeding an AI model with data from the 3D structures of existing materials, which then allows the user to ask the model to design the structure of a new material based on a simple prompt.

Its understanding the physical using AI to spot patterns in the way that atoms interact and accounting for these emergent properties, says Godwin. You would put in a prompt, and then a 3D material structure for that prompt will be generated. A prompt might be something like a CO2 capture material within a certain absorption capacity.

Orbital will be using the new material designs generated by its AI model to create its own products, with a carbon capture device being the first (carbon capture machines use specialised materials to absorb CO2 from the air).

Bringing new hardware based on novel materials to the market is more capital-intensive than the typical VC software bet, but Godwin says that the market for climate solutions is only moving in one direction.

How much money does the world spend on waste disposal and environmental remediation so cleaning our drinking water, removing the waste from our dust bins? Its about a trillion dollars, if you add [it] all [up], he argues.

Since launching in September 2022, Orbital Materials has raised early funding from AI-focused Fly Ventures and grown its headcount to 12, with more hires coming down the track, as Godwin makes the transition from research engineer to company leader.

Its certainly been challenging at times and Ive definitely had to acquire new skills, he says.

But I feel hugely passionate about what Im doing. And I think that passion is shared by my team, and thats a huge boon for us.
