My two cents: Thing is it&#x27;s not SaaS software because the value in SaaS is near 0 marginal costs to add new users(outside marketing). Also, it sounds like you have a niche type of user. So, the virility factor would probably be lower(lower marketing costs).  Not to say you can&#x27;t build a big business just outside financing would be difficult and of little value. If you try to grow to fast and can&#x27;t train your experts properly you will lose customers. And if you growing at a decent pace anyway you only save a couple of years to give up a bunch of your company.
