Ask HN: How do you cancel your startup, after adoption?
Some background: I'm about to start building a startup, because I'm fairly certain that one of the companies, in that space is going to crash in about 2-3 years. I would really like to take their customers from them (customers == organizations, about 30, I'm certain that about 10 of these are willing to pay for my software). They're (crashing org) making a software which requires updates like once or twice per year, due to legislation changing. Since, they're going to crash, or at least discontinue their product, organizations that purchased this product, have about half a year to adopt a new solution. My software is going to require same HW as their's does, so there's no upfront cost for these organizations. Switching to another HW is a question of about $15k in total, and 2 months of work. I've decided to label the software as SAAS (self-hosted, can't decide between monthly/yearly payments), since competition does this as well. My problem is that this competition is a corportation that can offer price around 10x lower than mine. Basically what I would like to ask per month (monetarily), they ask per year, since they operate at big scale.
My question: Let's say, that organizations, in need of my new software (about 10 at least) adopt it. I don't know if I will be able to acquire new customers (since the corporation can offer better pricing, support, everything). However, once those companies adopt my new software and I realize that it's not worth it, how do I undo my work? I'm really scared that I will be unable to acquire new customers, and eventually have to maintain this old money-loosing software. If I just decide one day, to not continue developing this product, can't they sue me?
PS: Is HN a place to ask these kinds of question? If not, where should I ask?
Thanks in advance.
