About Radius

Radius Technology Systems builds settlement infrastructure for the AI economy. Boston-based. The team spent the prior decade at the institutions that designed the financial infrastructure Radius replaces.

The team

Federal Reserve Bank of Boston — The core Radius architecture comes from Project Hamilton, a joint research effort between MIT's Digital Currency Initiative and the Federal Reserve Bank of Boston. The project produced PArSEC (Parallel Architecture for Serializable Execution) — the parallel transaction processing system at the core of Radius. Project Hamilton ran from 2020 to 2022 and published its findings openly.

MIT Digital Currency Initiative — Multiple team members contributed to CBDC research and the theoretical foundations of high-throughput stablecoin systems. The DCI's work on payment system design directly informs Radius's architecture.

Circle — Radius team members co-created USDC — the largest USD-pegged stablecoin by institutional adoption. They built the production infrastructure behind USDC: minting, burning, fiat on/off ramps, custody, and compliance at scale. Building USDC meant solving real problems in stablecoin infrastructure — problems Radius's architecture addresses at the network layer.

Zcash — Radius includes Zcash co-founders and contributors. They brought deep zero-knowledge cryptography expertise from building one of the earliest production privacy-preserving blockchains.

The thesis

The internet monetized itself through advertising because money couldn't move like data. Payment infrastructure — card networks, ACH, wire transfers — was built for human-initiated multi-dollar transactions. It never scaled to sub-penny micropayments.

AI changed the demand profile. Agents don't click ads. They make purchase decisions at volumes and speeds no human can match — hundreds of per-request payments per task, fractions of a cent each. Existing rails can't handle the volume. Blockchains add replication overhead that makes the economics impossible at sub-cent price points.

Radius builds the payment layer that works the same way the rest of the internet works: per-request, programmable, at near-zero cost. The same architecture that makes Radius fast makes micropayments viable — no global replication, parallel execution, stablecoin-native fees.

The agentic internet needs a settlement layer. That is what Radius builds.
