Ehsan's Analysis
AI/ML LTV:CAC is the most uncertain metric in tech right now because neither LTV nor CAC is stable. LTV is uncertain because AI customers are still figuring out whether they need AI tools at all — retention data older than 18 months does not exist for most products. CAC is uncertain because AI marketing channels (Product Hunt launches, viral demos, Twitter hype) are non-repeatable. The AI company that went viral once cannot count on going viral again. Calculating LTV:CAC for AI companies requires extreme conservatism: use 12-month observed LTV (not projected), use fully-loaded CAC including inference costs during free trials, and discount the ratio by 30% for "uncertainty tax." Most AI companies that apply this honest calculation find their LTV:CAC is 1.5-2.5x — survivable but not the 5x+ they present to investors. The AI LTV:CAC will stabilize as the market matures, but right now, any AI company claiming 5x+ LTV:CAC is either a market leader with structural advantages or is lying about one of the two variables.
