For me domain experience counts for a lot - and is crucial at all points in the process... from problem discovery + solution development through to how you go sell and market your service. What domain experience in the b2b-facing world do you have? Have you worked in a corporate environment and been part of processes that could be made more efficient via technology? Perhaps you have worked in a specific vertical like retail, real estate, accounting etc and can think of pain points there. Or perhaps you haven't. And that's also my point. If you haven't experience any of these pain points then how can you really put yourself into the place of the user or the person who will decide to purchase your service. How will you even know how to market it - use the correct language, know which places to advertise, how to create word of mouth, etc? When things are really low and the business is struggling, etc where will you find the passion and the drive to wake up in the morning and still be pumped up about what you are building? How will you keep the fire in the belly burning if you've never had the problems you are building for?
