i liked https://roundtable.ai/survey/9593255a3aa7231051e75e578747eae... as a multistep option
good luck - i think its an important problem but idk if its venture scale yet. you might explore RLHF/AI data annotation as a usecase.
i'd be most concerned about botting and filtering out low effort surveys - the latter i imagine is a big academic concern. if you came out with a singular innovation there you could probably build a company around it.
