A) C-suite types are extremely bandwagon-y. If their peers (real or imagined) are posting about it on LinkedIn in the typical breathless house style, they're going to at least investigate it.

B) C-suite types are also usually non-technical, so a dog and pony show that goes from 10 word prompt to working application is extremely impressive to them. Not that they're gullible or stupid by any means. They just are confident about making decisions with imperfect information.

C) In at least a few cases the frontier labs have strategically planted moles on corporate boards who then of course say the business needs to move faster, of course using AI, of course with their company's products. Conflict of interest? Never heard of it.
