My own experience was that the printers never worked, the billing had errors, their mail and visitor notifications never worked... so while I agree they fashion themselves as a tech company, they were really bad at it.
Oh sure, their stuff only kinda works -- like the products of a great many tech companies. But at the end of the day -- well enough to have people lining outside the door. And they can't seem to stake out new buildings fast enough to keep up with the demand.
It's an interesting gedankenexperiment... we were with them for 18-24 months (I don't remember now...)... it was just an ok experience, and at a premium price. I don't imagine I would use them again. So do they continue to thrive, or does the veneer eventually fade and they are stuck holding some very expensive leases?
A successful tech company, through and through.
