Monitor the r/sales and r/entrepreneur subreddits for users complaining about ZoomInfo's pricing or lack of integration support.
Saw your comment about looking for a ZoomInfo alternative. If you're dealing with getting your data to actually talk to your AI tools, we've built a managed platform specifically for that. Happy to show you how we handle the integration side.
