As answered by people managing ZoomInfo and Stacksync.
Stacksync's answer:
Stacksync's answer:
Stacksync is built for teams that need reliable, real-time data sync at scale. Unlike automation or batch ETL tools, it provides sub-second, bidirectional synchronization without API limits, complex scripts, or per-row pricing surprises.

Stacksync was created to solve a common problem faced by data and engineering teams: keeping business systems in sync without relying on fragile scripts, slow batch jobs, or API limitations.
