Charles Hoskinson is the CEO and Founder of Input Output Global (IOHK), the company behind the Cardano blockchain, a proof-of-stake platform hosting the ADA cryptocurrency. A mathematician by training, Hoskinson co-founded Ethereum in 2013.

He launched IOHK with Jeremy Wood in 2015, raising $62 million in a 2017 ICO for Cardano, initially targeting the Japanese market before global expansion. Hoskinson advocates for decentralized governance, as seen in Cardano’s 2024 Voltaire framework and 2025 Wyoming Integrity PAC to challenge state stablecoin policies.

His ventures extend to longevity science, with a $100 million investment in the Hoskinson Health & Wellness Clinic in Wyoming, and quirky pursuits like glow-in-the-dark botany and a 2023 Papua New Guinea expedition for extraterrestrial objects. With a net worth estimated at $1.2 billion, he owns an 11,000-acre Wyoming ranch and remains a vocal critic of centralized control in crypto.
