And, you're exactly right. The online world of people specifically interested in tools for ranked-choice voting is quite small. The question I'm trying to answer is what use cases does ranked-choice voting work better than other existing survey/polling options? That way, someone could be looking for a solution to that specific problem. Right now, most of RankedVote's users are already aware of RCV and then try to apply that in some scenario at work where a simple voting tool would have been the alternative.
ranked choice is a primitive form of conjoint analysis, so that might be an avenue for exploration. marketers aren't always statistically rigorous in how they poll and analyze markets (which is one of the reasons product management rose in prominence, because of the promise of more analytic rigor). even simple versions of conjoint can be an informative tool in the toolbox, but the studies and the existing tools are expensive.
i don't know for sure that there is a big enough market there for VC, but i'm sure a good marketer could make a nice business out of it.
I think the market specifically for “Ranked-Choice Voting” is probably way smaller than the need for “easy/better/awesome polling and survey tools”.
Just keep that in mind as you grow and good luck with everything
