Even by the turbo-charged standards of Silicon Valley, the three-day surge in the fortune of Anthony Wood has been meteoric.

The chief executive officer and founder of Roku Inc., a maker of home streaming devices, added $652 million to his net worth since the company reported third-quarter results on Wednesday, giving the technology industry’s latest billionaire a $1.07 billion fortune, according to the Bloomberg Billionaires Index.

Shares of Roku have more than doubled since the earnings report, its first as a public company, as revenue and active users surged. The gains continued Monday after Roku announced a nationwide discount on its streaming stick ahead of Black Friday, with the stock advancing 29 percent to $42.80 at 1:43 p.m. in New York.

Tricia Mifsud, a spokeswoman for Los Gatos, California-based Roku, declined to comment on Wood’s wealth.
