Summary
🤩
RockstarJed Mccaleb is a serial founder and seasoned software engineer with 14 years of experience building decentralized systems, payments infrastructure, and consumer software from San Francisco. He co-founded Ripple and Stellar and has deep hands-on experience across C++ blockchain daemons and web UIs—evidenced by contributions to the XRP Ledger's rippled core and the Ripple payment client. Currently founding Vast to build artificial gravity space stations and Astera Institute to back high-leverage science projects, he blends ambitious moonshot vision with practical protocol-level engineering. Earlier work includes pioneering peer-to-peer file sharing at MetaMachine (eDonkey) and designing indie games, demonstrating a long track record of shipping distributed systems and user-facing products. He combines protocol design, low-level consensus and serialization work with front-end UX chops, and often moves between research, nonprofit impact, and commercial ventures. A less obvious thread: he consistently channels deep technical craftsmanship into organizations aimed at broad societal or planetary-scale impact.
