Of course it reads like a press release. Most stuff here, and everywhere else, does.
However what the Zerto guys are doing is very cool. This is real-time replication with a lot more built-in. If I want to move from a VMware-based cloud to Azure, I point and click. When it syncs I can failover over a multi-VM application in a few minutes. That includes full network failover.
Converting formats is one thing. Doing it with zero data loss and a downtime window of a few minutes is very cool. Doing it with software that is completely independent of the hardware and hypervisor infrastructure is also very cool.
