5 growth marketing mistakes killing your SaaS CAC

We've audited over 50 SaaS companies in the past 18 months. 80% of them were making the same five mistakes that kept their CAC high and payback period long.

Mistake #1: Spreading budget across too many channels Most founders panic and run ads on Google, Meta, LinkedIn, and Reddit simultaneously. This creates attribution chaos and prevents learning at scale. Pick one channel, master it to a 3:1 LTV:CAC ratio, then expand.

Mistake #2: Targeting decision-makers, not users B2B buyers aren't monolithic. Your ICP needs segmentation: users (who try it), influencers (who recommend it), and approvers (who buy it). Most SaaS focuses only on approvers.

Mistake #3: Optimizing for clicks, not conversions High click-through rates mean nothing if your landing page converts at 2%. Every dollar in ads is wasted if your funnel can't capture it.

Mistake #4: Ignoring your existing customer base Acquisition is 5-10x more expensive than expansion revenue. If you're not upselling, you're leaving money on the table.

Mistake #5: Not measuring unit economics Too many teams don't know their true CAC, LTV, or payback period. You can't optimize what you don't measure.

These aren't theoretical. We've helped clients reduce CAC by 58% using these frameworks.
