Why not just get a job and continue building your startup on the side, if the response is mildly positive, then figure out what other problems you could solve to make it overwhelmingly positive. The sales cycle is much longer for B2B products and if you don't have a ton of competition, then getting a job and building this on the side is an option worth pursuing. There's definitely an opportunity there, you just need to make sure you refine your product to hit it.
