Keira, my two cents is that it depends on the industry you are in. for example, I am in the oil and gas industry (currently working on a product in my free time as a hobby in the evening), but in my industry (Oil and Gas), there is fierce competition in products and a lot of companies are advertising lots of things in order for you to even get a change to work/access Decision Professionals (generally engineers) you have to have good marketing for them to even give you a shot as a beta user. if it looks non polished, it gives it another reason for impeding growth. We are planning a hearty budget for marketing (10-20K). I understand there are couple school of thoughts on this but in the oil and gas industry it is a must and not an option. Please evaluate your industry and talk to people who are experienced in your industry to get insight, then make a decision.
Good luck!
