Also, most people should let go of the silicon Valley or US mindset that success means 'a significant portion of your target market'. We do not all have to or want to be billion$ company founders or grow fast or have many employees; it is fine running a small SaaS that gives you 500k-1m revenue/year and you run on your own. Maybe not in the US (I know too little about the Healthcare and litigation parts), but in the EU, you can live and retire as a king with those numbers (provided you don't do things that are too stupid along the way). With such a company, you do not need much to differentiate to get 1000+ paying clients: you just probably will never get to millions of clients, and that is OK.
