What this means for your account

Your unit economics are at risk.

At this ratio, you're barely making money after CAC. The buffer is too small to absorb operational costs (overhead, customer service, fulfillment, taxes). This isn't sustainable unless either CAC drops or LTV expands.

This is the situation the Free Quick Scan was built for. Private Loom, no account access, 48 hours.
