The price for design software developer Figma surged more than 250% on Thursday to close at over $117 per share after raising over $1.2 billion in an IPO, well over three times the $30-$32 range the company estimated in SEC filings earlier this week—making its 33-year-old CEO Dylan Field a billionaire.

Figma Inc. raised $1.2 billion with an initial public offering on Thursday, with shares trading for $33, which increased its market share to $19.3 billion.

As a business, Figma appears to have a bright future ahead of it, but after tripling on its IPO day, the stock now has a market cap of roughly $60 billion, giving it a price-to-sales ratio (P/S) of around 70. That's a sky-high valuation for even the brightest of IPOs.
