December 5th, 2025— Input Output Global (IOG) today announced it has rebranded to Input Output (IO), marking a significant milestone in the organization’s evolution from a pioneering blockchain research and engineering company into a global leader in Web3 and frontier technologies that span everything from healthcare, quantum computing, digital identity and fintech.
The rebrand reflects the organization’s evolving product portfolio and international footprint. The full group of affiliated projects—including RealFi, Lace, and other associated subsidiaries—will now operate under the umbrella name Input Output Group.
Originally established to research and build the foundational infrastructure behind Cardano—one of the world’s most prominent blockchain protocols known for its industry-first on-chain Constitution—Input Output has grown into a global multi-disciplinary organization delivering advanced emerging technology solutions across scalability, interoperability, digital identity, privacy, high-performance computing, and real-world industry applications.
Charles Hoskinson, CEO of Input Output, said: “This rebrand marks the natural next step in our journey. Input Output has grown far beyond its original structure, and today we are a global engineering organization working at the frontier of research, infrastructure, artificial intelligence, privacy, fintech, healthcare, and Web3. The name Input Output captures our commitment to solving hard problems and building systems that endure. It also reflects our mission: to improve the systems of the world for everyone, everywhere. As Input Output Group, we are entering a new chapter of expansion, investment, and innovation across the United States, Latin America, Europe, the Middle East, and emerging markets.”
Today, Input Output supports a dynamic ecosystem of technologies it has built, maintained, or incubated into independent projects, including:
- Cardano – a globally distributed blockchain platform built for security, sustainability, and scalability.
- Midnight – a privacy-enhancing blockchain for data protection, compliance, and enterprise use.
- Daedalus and Lace – next-generation wallets enabling secure access to the Cardano ecosystem.
- Hydra – a layer-two scaling solution for high-throughput applications.
- And more - tools, research frameworks, and developer infrastructure supporting real-world blockchain adoption.
The transition to the new brand identity is now reflected across websites, communication channels, product documentation, and corporate materials. Existing products and research initiatives will continue uninterrupted, and all services under the former Input Output Hong Kong and Input Output Global names will now be delivered under Input Output or Input Output Group, as appropriate.
