Yes. The difference is that if one employee at a large company gets hit by the “lottery bus” or loses interest, the business doesn’t go under.

Also some companies like Microsoft, Salesforce, AWS etc are more trusted by “the enterprise” than Google.

Is there an easy process for your customers to move their data over to a similar service if they don’t want to renew the contract?

The combo of data exports and open-sourcing your code is a great solution to this problem. If you vanished tomorrow customers could easily migrate to a different vendor or even self-host. That carries much less risk than betting on any early stage VC startup that might vanish overnight, even with more people involved.
