Many of us have built tools, protocols, and companies that are among the most used on the internet. We write software, much of it open source, and we incubate new companies, from developer tools like Foundry and Reth to Tempo, a payments network we created with Stripe. We also build alongside others, including security evals with OpenAI.
Open Source
Paradigm builds and contributes to projects that advance the frontier. We believe in doing so even when there may not be a direct commercial incentive.
