OpenSea - A Good Example of Something That Started Super Simple

OpenSea is a company in the zeitgeist. It feels like it came out of nowhere. And they actually spent something like a year to two years grinding it out with this really simple website that just let you buy and sell NFTs. They didn't build their own wallet. You have to use a third party wallet. There's all these other things they didn't build. By grinding away and being super focused on the simple use case, they got something that people wanted.
