1. Pivoting away from revenue is pretty stupid thing to do. If you are buying from me, and so is Tom Dick and Harry, I am getting a strong market signal.
2. The team is so good they might get acqui-hired and you are worried your multinational company is now relying on them - well there is a solution to stop another company acqui-hiring them....
3. Customer service sucks most places. Some use it as a differentiator (Rackspace), but a lot of the time customer service should be automated (lost your password?). And "on-boarding" new customers by hand - this is gold that some startups are learning about
4. I will happily send you an invoice and set up a monthly billing run. It just won't be for 29 dollars a month :-)
But yes - I agree with your main thrust - we should make it easy and simple to get a yes turned into a paid invoice from a corporate budget holder.
