Typically I would agree, but in the case of OpenAI, they were themselves blindsided when their free conversational LLM demo, ChatGPT, went viral less than a year ago now.
It is a rare counter case, where a tech-focused research demo, without any clear "product-market fit, suppliers, or customers" became a success almost overnight, to the surprise of it's own creators.
The early days were people playing around with ChatGPT just to see what it could do. All the market fit, fine tuning, and negotiation of deals came later.
Of course, OpenAI capitalized on that initial success very skillfully, but Ilya was the critical world renowned AI researcher who had a lot to do with enabling OpenAI's initial success.
