Ratio of customer lifetime value to acquisition cost. 3:1 or higher indicates healthy unit economics.
LTV / CAC
Higher is better · Unit: ratio
How to Improve
Target higher‑value customer segments where LTV naturally outpaces acquisition cost. Reduce sales cycle time through better qualification and automated demos. Create land‑and‑expand playbooks that start small and grow accounts over time. Focus marketing on ICP accounts rather than broad awareness campaigns. Optimize pricing to capture more of the value you deliver.
Ehsan's Analysis
DevTools LTV:CAC has a measurement problem: the "C" in CAC should include the massive investment in free tiers, open-source maintenance, documentation, and community that generates demand but is classified as R&D, not sales & marketing. If you reclassify community investment (DevRel team, conference sponsorships, open-source contributors, free-tier infrastructure) as acquisition cost, most DevTools LTV:CAC ratios drop from 5-8x to 2-3x. This reclassification is more honest because removing any of these investments would immediately reduce new customer acquisition. The DevTools companies with genuinely high LTV:CAC even after reclassification — HashiCorp, Datadog, MongoDB — built products that generate enterprise demand organically through developer adoption, requiring minimal traditional sales investment. Their "unfair advantage" is that the R&D investment simultaneously serves the product AND the acquisition engine.
