Hi Alex,

Great question about scaling the integration! We work with several 200+ person agencies like yours.

For Acme Agency (similar size), we set up our Slack → CRM sync which saved their team 15+ hours/week on data entry. Their operations director said it was "like hiring an automation specialist without the cost."

Here's what I suggest:
1. I'll show you the integration setup (10 mins)
2. We'll discuss your specific workflow
3. You'll see exactly how it works with your stack
