Unlike millions of people, Cloudflare co-founder and CEO Matthew Prince is betting Friday the 13th is his lucky day: it's the date on which he's taking his cybersecurity startup public this month.

The 10-year-old company could raise as much as $483 million at a $3.5 billion valuation on its initial public offering, based on the higher end of an initial price range of $10 to $12 per share announced Tuesday. Cloudflare, which was last valued at $3.2 billion, could still increase its price range in the coming days as it gauges investor interest. The company is expected to issue a final share price on September 12 and start trading on the New York Stock Exchange under the ticker symbol "NET" the following morning, according to the NYSE's website. While other entrepreneurs may choose to avoid doing business on Friday the 13th, Prince, who was born on November 13, is rather fond of the otherwise infamous date.

"Turned 13 on Friday the 13th. 13 letters in first + last name. M is the 13th letter in the alphabet. Always been a lucky day/number for me," Prince, now 44, tweeted on a Friday the 13th in 2015.

If Prince's lucky streak continues, here's how much he and other big Cloudflare stakeholders stand to gain after the company's IPO. (The post-IPO stake numbers are calculated based on the number of outstanding shares after the offering, assuming the underwriters do not exercise their option to buy and sell up to 5.25 million additional shares, in a move known as a "greenshoe option."
