Nearly twenty years ago, Anthony Casalena was a student at the University of Maryland who wanted to build himself a website. Finding no easy platform in the market, he created his own. Today, Squarespace is an all-in-one website building and e-commerce platform used by more than 4.2 million people. Anthony worked as a team of one for the first few years but now has over 1,800 employees, having taken Squarespace public in 2021. Here, Anthony shares how he got his idea off the ground with a $30,000 investment in servers and Google AdWords, why it still feels surreal to see a Squarespace ad at the Super Bowl, and how running a public company is completely different from what he expected.
