 Wiz was founded in 2020. It had been eyeing an IPO as recently as May when it achieved a valuation of $12 billion. The cost of a first-class stamp is now 73 cents. The Postal Service raised that price by 5 cents yesterday. It's the second increase this year. Stamps aren't the only thing that went up. The cost for bulk mail, postcards, and packages have gone up too.
