Paradigm

A research-driven technology investment firm.
paradigm logo

Paradigm is a research-driven technology investment firm. Our approach is flexible, long term, multi-stage, and global. We often get involved at the earliest stages of formation and continue supporting our portfolio companies over time.

We take a deeply hands-on approach to help projects reach their full potential, from the technical (mechanism design, security, engineering) to the operational (recruiting, regulatory strategy).

This Github Organization hosts all of Paradigm's open source experiments, designs, and production-ready code.

Among other things, we are currently building:

  • Tempo: The blockchain for payments. Incubated with Stripe.
  • Reth: Modular, contributor-friendly and blazing-fast implementation of the Ethereum protocol, in Rust
  • Centaur: Centaur is frontier, agentic infrastructure that you own. Centaur is like Claude Tag, but open source and on steroids.
  • Iron Proxy: An egress firewall for agentic untrusted workloads.
  • Foundry: A fast, portable and modular toolkit for Ethereum application development written in Rust.
  • Solar: A blazingly fast, modular and contributor friendly Solidity compiler, written in Rust.
  • Alloy: High-performance, well-tested & documented libraries for interacting with Ethereum and other EVM-based chains, in Rust.

We also support third party open source projects and organizations such as:

You can learn more about our research and building at the Paradigm website.
