Pre-existing and they left because of tech/service issues. We interview all outgoing customers.
And I agree our lack of preparedness to scale was part of this, but it's shortsighted to only look at a simple conversation rate for determining success.
"Success" is relative and we define it on a higher level than just conversion. The fact is, software isn't infinitely scalable...or rather it takes orders of magnitude more resources for it to approach that level.
There's a certain inflection point where the time spent "getting prepared" simply outweighs the potential benefits. We could have spent years "getting prepared" but there was a point where we just had to say "ship it"...and that's what we did.
