## Description

You're trying to figure out if your outbound team is actually worth the spend or if your inbound leads are dragging down your margins. This Connector handles the heavy lifting of unit economics by digging into your channel data across different customer segments like SMB and Enterprise. Instead of you manually pulling numbers into a spreadsheet to see who's winning, you can just ask your agent to find the leaks. It looks at things like your Sales Efficiency Ratio and tells you exactly how many months it takes to recover your CAC. When you find a channel that's underperforming, it doesn't just leave you hanging. It shows you where you can move your budget to hit your targets faster. It's a core part of the Vinkius catalog, making it easy to plug into your existing stack and get clear answers on your growth spend. You can see which specific marketing vectors are actually paying off and which ones are just burning through your quarterly budget. This means you can stop guessing and start making decisions based on the actual math of your acquisition costs.
