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.
