I can’t help myself to think that nowadays, products UX/UI level is so high, that even for B2B products, people have expectations.
I would certainly not use a product that looks and feels crappy even if it solves my needs.
I could possibly don’t see how it solves my needs if it does it in a crappy way too.
What are your thoughts?
I believe you are looking for Minimum Lovable Product (MLP). Unless you are serving a very niche market where existing options are total crap, nowadays users can find direct/indirect alternatives easily, making the “viable” threshold so much higher.
Also, UXUI could play a larger part of the “viability” if you your target audience are more towards designers isn’t it?
