OpenSea
OpenSea is an American non-fungible token (NFT) marketplace headquartered in New York City. The company was founded by Devin Finzer and Alex Atallah in 2017. OpenSea offers a marketplace online allowing for non-fungible tokens to be sold directly at a fixed price, or through an auction. History Devin Finzer and Alex Atallah founded OpenSea in December 2017. They were inspired by CryptoKitties, a blockchain-based game featuring non-fungible tokens that had been released earlier that year. Finzer and Atallah believed that OpenSea could be a marketplace for buying NFT tokens like those at scale. They entered Y Combinator's accelerator program in 2018, where OpenSea was described as a "peer-to-peer marketplace for cryptogoods". After a 2018 pre-seed round by Y Combinator, OpenSea raised $2.1 million in venture capital in November 2019. In March 2021, the company raised $23 million in venture capital; four months later the company announced another investment round of $100 million making it a unicorn. In March 2020, the platform had 4,000 active users completing $1.1 million in transactions a month. By July 2021, users were completing $350 million in transactions a month, and the company was valued at $1.5 billion after a $100 million Series B venture round
