It depends on whether you have one or multiple snapshots, and whether you reverted to the current (latest) snapshot. If you reverted to the current (latest) snapshot, all changes were discarded and your only option is to restore the database from a backup (which if I understand you correctly, you unfortunately don't have!?).
If the VM has multiple snapshots, and you reverted to an older snapshot (i.e. not the last one in the chain), there might be a chance to set the VM to a newer snapshot. However, unless you created a snapshot prior to reverting to an older snapshot, the latest data is most likely lost, and only a data recovery company may be able to help with recovering the data.
