Yes, if any of them will actually do it. Personal accounts consistently outperform company pages on LinkedIn, and buyers trust a named person over a logo, particularly for considered purchases.
This works best when the executive has real opinions and a workable process, which usually means a ghostwritten draft they rewrite heavily rather than a finished post they approve. It fails when posts are written for them and published unchanged, because the voice gap is obvious to anyone who has met them and embarrassing to anyone who works for them.
The same logic extends past the C-suite, since a handful of engineers, account managers, or field technicians posting about their actual work outperforms a corporate content calendar.
