Weirdly I feel like the fact that you are profitable and have large customers could be as important a part of your customer pitch as it is your investor pitch - even if the tech is awesome that trust in the organization to stick around is super important (just look at the trouble around stadia haha). It's like those fintech companies that have "but how do we make money?" To make sure customers know "ok they can make money without screwing me over or ending up having to shut down"
Could you elaborate? :) Because otherwise, you're possibly sending the same message as what I alluded to (i.e., we feel great because we're expecting a big exit).
Well, whoever buys them would like to keep the customers, as it is already a profitable business. So, even if they completely close the business, they should provide a way to migrate, as nobody likes to loose money/customers.
