About This Metric

Total cost of acquiring a new customer, including marketing, sales, and onboarding expenses.

Total Sales & Marketing Spend / New Customers Acquired

Lower is better · Unit: currency

How to Improve

Shift marketing budget toward product‑led growth motions where the product itself acquires users. Double down on community‑led acquisition by nurturing developer or practitioner communities. Implement lead scoring to focus sales effort on accounts most likely to convert. Negotiate better CPM and CPA rates by consolidating ad platform spend. Explore partnership channels for lower‑cost co‑marketing opportunities.

Ehsan's Analysis

AI/ML startup CAC is uniquely bifurcated: horizontal AI tools (writing assistants, image generators) have consumer-like CAC of $5-30 driven by viral product demos, while vertical AI solutions (legal AI, medical AI, manufacturing AI) have enterprise-like CAC of $20,000-100,000 driven by long sales cycles. The dangerous middle ground is where most AI startups live: too technical for consumer virality, too horizontal for enterprise sales. Jasper grew from $0 to $80M ARR with $20-40 CAC through influencer partnerships and product-led virality, then pivoted to enterprise and watched CAC jump 50x. The AI CAC truth: if your product requires custom model training, data integration, or more than 15 minutes of setup, you are an enterprise product regardless of your pricing page — budget and plan accordingly. Self-serve AI products must deliver value within 60 seconds of signup or the CAC math breaks.
