A little bit of everything. No one knows if this will work because I don't have customers, and it looks like a feature and I can't explain that it will be more than this single product, investors are getting lost. It's impossible to make this startup without a weird path. It's going to be an API in the end, but at the same time I have to show what products are possible to make with it, most think this API is not needed and won't let me put a library in their products, but if you'd talk to potential end customers for these products - they really want it (and I sold multiple products like these). It's a totally weird scheme, so I only pitch the b2c product and then if they are interested tell about this API thing and the vision.
Market is just above 4B$ and is growing well, but it's not like everyone in the world needs this thing.
I have no startup experience, not an amazing dev (barely made an mvp) , never attended Stanford and live in a third world country, so I don't even have connections and rely on highly personalized cold emails.
