Investment thesis

8 Decimal Capital began in 2017 as a crypto and Web3 investor, then shifted in 2021 into a family-office structure investing solely with founder capital after its founder moved full-time into building Parallel Finance. In late 2025 it broadened its mandate with a founder-led approach spanning three areas: AI & robotics (video and world models, agents, humanoids, robotics foundation models, industrial robotics), crypto & Web3 (stablecoin payments, privacy infrastructure, decentralized exchanges, prediction markets, DePIN), and deep tech (quantum computing, brain-computer interfaces, nuclear fusion, space exploration, material science, longevity). It writes early-stage checks of $500k to $2M depending on stage and conviction.
