a whole startup? well off the top of my head, I think there is definitely some interesting stuff happening with the GPT agents like Auto-GPT and BabyAGI, potentially expensive with GPT-4 but I presume those would help developing the business plan-- I'm always curious about niche opportunities for SaaS but UX is slightly different--- I can imagine some cool experiments where you could have some kind of GPT agent working in a docker container where you would use the GPT-4 image recognition feature to iterate over visuals, in that, you could supply samples for inspiration, have the code execute until it gets it right-- but crucially you'd need the write testing and checking in place, like linting, selenium etc... then. maybe I'd have automated galleries where customers could evaluate things, it could potentially be automated entirely-- quite a bit of work but I can definitely imagine a business idea or 3.
