mission
Most customer success tools treat every account the same a ticket to resolve, a metric to track, a field to update. They're built to scale support, not to scale relationships.
Round is different. AI agents run across your entire customer base, connecting signals from emails, calls, and product data — giving CS teams, account managers, and executives the full picture of what's happening, what needs attention, and where to go deeper.
