That takes time and money on OpenAI's behalf. Alternatively they can aquire Bloop after Bloop does all the leg work of integrating their niche with chat GPT. But I agree its a tenuous place to be in as an investor / employee / cofounder of a startup that is at OpenAI's mercy. This model of relying on another vendor's product to base your own saas product on has worked in the past, and it has also failed in the past.
