Scaling Trust

Backed by nearly £50m, this programme sits within the Trust Everything, Everywhere opportunity space and seeks to create the capability for AI agents to securely coordinate, negotiate, and verify with one another on our behalf.

Our goal

AI agents are already writing code, browsing the web, managing workflows, and beginning to act in the physical world. But while individual agents grow more capable by the day, they still can't securely coordinate with each other, especially in real world scenarios when the stakes are high, the parties are untrusted, and the environment is adversarial.

We are missing the trust infrastructure that would move them from solo operators to secure collaborators. Without it, agents remain either powerful but isolated or acting in the wild with no security at all.

This programme is building that infrastructure: open-source tools and scientific foundations for agents to securely interact across digital and physical worlds, combined with a live adversarial arena to stress-test everything we build.

Success would unlock a new era of coordination that preserves our plurality, protects our privacy, and creates value we can't yet fully imagine.

Programme tracks

This programme is split into three mutually reinforcing tracks:

Track 1

Arena

A platform for open competitions designed to test AI systems’ capabilities in multi-agent coordination across digital and physical worlds, with a multi-million pound prize pool for the strongest teams.

Track 2

Tooling

Open-source coordination infrastructure usable by all in the Arena and beyond, to steer innovation toward the most meaningful axes of progress.

Track 3

Fundamental research

Theory that helps move us from empirical to theory-driven guarantees, and that helps us design new security primitives that can aid agentic coordination.

Funding for Tracks 2 + 3 now open until 24 March 2026

We’re looking to fund projects across our Tooling and Fundamental Research Tracks, developing open-source coordination infrastructure for AI agents as well as building upon fundamental research into areas such as cyber-physical primitives and generative cryptography.

The Scaling Trust Arena

The Scaling Trust Arena is planned to launch in Q3 2026. We’ll be putting out a call for a technical partner to build and deliver the Arena in the coming months. If you’re interested in applying, please submit your expression of interest so we can let you know as soon as the call is live.

Alex Obadia

Programme Director

Alex is an entrepreneur and investor in early-stage frontier technologies, with a keen interest for quantum cryptography. Previously, he co-founded Flashbots, a software unicorn dedicated to safeguarding the decentralisation and permissionlessness of the Ethereum blockchain. Flashbots’ products have helped generate nearly £2bn so far and its R&D sparked the 'MEV' industry.

Sarath Murugan

Programme Specialist

Sarath joined ARIA from a business operations and strategy role in a defence engineering scale-up, where his team developed a product that brought the capabilities of gen-AI to the disconnected-edge. He holds an LLB from Bristol, and has experience in project and product-facing roles. Sarath supports ARIA as an operating partner from Pace.

Nicola Greco

External Technical Advisor

Nicola is a cryptography researcher and investor. Over the last decade, he has led Protocol Labs’ Cryptography R&D team who pioneered the use of zero-knowledge cryptography in production systems, and was the first check in multiple unicorns. Formerly, he was a fellow at the Harvard Center for Internet and Society and a PhD student at MIT advised by Tim Berners-Lee, inventor of the World Wide Web.

Edith Web

Edith-Clare Hall

Frontier Specialist

Edith works alongside the Programme Directors to scope out emerging areas of technology that can shape current and future ARIA programmes. Her doctoral work is in Soft Robotics and Engineering Mathematics at the University of Bristol, where she has developed bespoke wearable robots for progressive disease, leveraging novel hardware and AI.

We're hiring a Technical Specialist
