Blur is the leading NFT marketplace for professional traders. Since our public launch in October 2022, Blur has become the #1 aggregator for NFT trading on Ethereum, surpassing billions of dollars in trading volume and attracting hundreds of thousands of users worldwide. In 2023, we launched our governance token, $BLUR, and established the Blur DAO, further decentralizing our platform's direction and growth.

We're a small, high-powered team with trading and systems backgrounds from places like Facebook, Five Rings Capital, and MIT, and we're remote friendly with an office in SF. We've built spot exchanges, marketplaces, and created financial products used by millions, and we're growing our team to help us build the best trading tools on the market.
