Yes I posted that re appsumo, I had meant to post it here as a quote but somehow sent it as a pm. Apologies.
My understanding of appsumo is limited, but I understand they take a large chunk of the money raised, but exposure and suppor can be huge.
You might find approaching influencers in your product field with a free trial and then an affiliate link scheme, for them to promote it; if they like the software, would be a good way to start getting noticed?
My recollection is that KS was set up for (apart from making money) tangible product based ideas,that required access to production facilities or manufacturing techniques ordinarily unaffordable o in accessible, without capital support.
Your product is less about building it more about marketing it.
Maybe, perhaps what your research is telling you, that possibly the market is to first write code to build a software onl version of KS and then you can float your software product through it?
Perhaps others have ideas for software. I have a friend who has also written an application, he has been busy promoting it via offers and subscriptions, he’s won some plaudits for his application, good reviews and mentoring support. It is a hard struggle check it out reach out to him he maybe can offer some advice,
