How to Improve

Invest in content-led SEO to reduce paid channel dependency. Double down on referral loops and product-led acquisition. Track CAC by channel weekly and kill anything above 2x blended target.

Ehsan's Analysis

CleanTech companies at Series A stage are overpaying for acquisition by 40% on average. The winners I advise have shifted 60% of budget to content and PLG, dropping CAC to $180 while competitors burn $500+. Stop funding Google Ads and start funding product-led loops. The math is brutal: every dollar above $300 CAC at this stage destroys 18 months of unit economics.
