At Hiro, we build developer tools that bring Web3 to Bitcoin. Our suite of tools unlocks the full potential of Bitcoin through smart contracts, digital assets, and decentralized applications. With Hiro tools, developers can test and deploy smart contracts, spin up nodes and other server-side resources for scaling, and more. Building on Bitcoin is hard. Hiro's developer tools make it easier. We’re very proud to say that Hiro won 3 Built In’s Best Places to Work awards, including Best Places to Work NYC, Best Places to Work Small Companies, and Best Paying Companies NYC!

Hiro is funded and backed by more than $75 million from Union Square Ventures, Y Combinator, Lux Capital, Winklevoss Capital, Naval Ravikant, and others.
