How to Improve

Build a referral engine that turns every customer into an acquisition channel. Invest in bottom-of-funnel content that captures high-intent search traffic. Track blended CAC weekly and set alerts when it exceeds 2x your target.

Ehsan's Analysis

The Series C-stage MarTech benchmark data reveals a surprising pattern: companies with the best numbers here are not the ones with the biggest teams or budgets. They are the ones with the tightest feedback loops. Weekly measurement, daily standup visibility, and 48-hour iteration cycles separate top-decile from median performance. Build the system before chasing the number.
