No shortcuts, no compromise
What drives the work — and the people behind it.
Craft Over Commerce
Great software is both an art and a science. We hold ourselves to a standard where every system we build is carefully considered, refined to its essence, and built to last. Where others optimise for speed to market, we optimise for solutions that can adapt gracefully over time.
This means first-principles thinking over convention. Clean architecture over expedient shortcuts. Rigorous testing over hopeful assumptions. Quality is non-negotiable — not because perfection is the goal, but because the work matters and the details compound.
Principled Technology
We believe technology should empower individuals, providing digital freedom, privacy and genuine ownership. Not because it's fashionable, but because it's right.
We are, however, pragmatic about the gap between ideals and reality. Not every ambition is achievable on day one, and claiming otherwise helps no one. What matters is honest progress — deliberate moves toward those goals, transparency about where we are in the journey, and never compromising direction for convenience.
Rust-First
Those principles need a foundation that can back them up. We made a deliberate bet on Rust — not as a trend, but as that foundation. A language embodying the trade-offs we value — performance without sacrificing safety, expressiveness without sacrificing clarity, zero-cost abstractions that reward discipline. One language, applicable everywhere.
This philosophy guides every technology choice we make. Every dependency, every framework is a commitment — we choose deliberately and sparingly. We favour what compounds in value over time — tools and approaches that reward long-term investment over short-term convenience.
Collaboration, Not Transactions
We don't think in terms of clients and vendors. The best work comes from genuine partnership — shared ambition, complementary strengths, mutual investment in the outcome.
We invest in understanding the problem space deeply, not just the implementation. This means we're selective — opting for challenging work where we can bring our best, with people who care as much as we do about the result.
Emergent Technologies
Technology moves fast — each wave reshapes the landscape. What doesn't change is the need for rigour, adaptability, and the willingness to go deep on hard problems.
We bring the same engineering discipline to each frontier, applying experience to uncharted territory. We believe in demonstrating capability rather than claiming it — our work is the proof.
If you're building something ambitious and want a partner invested in the outcome, let's have a conversation.

Frank Bell
Founder
From hedge fund infrastructure to decentralised systems, bringing decades of full-stack experience to emerging technologies. Architecture-first, principled, with a practical focus on getting things built.
Background
Frank brings a background in Information Systems and extensive full-stack technology experience to the decentralised space. As head of technology at a London hedge fund for over a decade, he architected and delivered the firm's core trading infrastructure — order management, pre-trade regulatory compliance, and reconciliation systems — while owning operational due diligence, business continuity planning, and day-to-day technology operations.
The emerging Web3 movement caught his attention — the promise of a more open, equitable internet resonating with a desire for something beyond traditional finance. The programmability introduced by Ethereum, the ability to build complex decentralised applications beyond simple value transfer, was the revelation. He pivoted to blockchain and Rust, graduating from the inaugural Polkadot Blockchain Academy before spending several years deep in the Polkadot ecosystem, advising on and delivering projects incorporating light clients, oracles, parachains, smart contracts, and XCM.
He founded ERI to channel that experience into work that demands both technical depth and creative thinking — on his own terms. He's drawn to challenging work at the frontier — architecture-first, opinionated where it matters, and motivated by building things with purpose.
