Shares of software company Figma soared in their stock-market debut Thursday, rising more than 200% in one of the splashiest initial public offerings in years.The stock opened at $85 a share, more than twice its IPO price and the best first-day showing in recent memory for a major offering.

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.

Design startup Figma listed its shares on the New York Stock Exchange in a year when IPOs from buzzy tech firms have come roaring back.
