You joke, but something similar happened at my old company, and I suspect it's relatively common for serial entrepreneurs.

The founders, who are now flush with cash, time and ideas; are quickly speedrunning the steps creating their previous company, in the same market, but now with more access to capital and employees from their previous company who would rather work for a startup than a large conglomerate, while fixing all the mistakes from their previous venture.

I 90% meant that it was the skills, industry knowledge and connections/reputations they built before Wiz, but it is true that most companies are conceived and planned far ahead of their actually registrations. Sensible people don't exactly just quit their jobs and start a company in a few days. They conceive, do research, discuss and (I suspect in Wiz's case) prototype before they commit. Its definitely a smart move, there's a very real valuation and PR advantage if you delay your actual founding, so your time to X revenue looks shorter.
