This should not be misconstrued as a eulogy for the LTV formula. It has a very important place in business as a way to contrast and compare alternative marketing programs and channels. It is a tactical marketing tool that requires candor and thoroughness in its implementation. The fundamental reason that it is so amazingly dangerous and seductive is its simplicity and certainty. Generic marketing is conceptual. LTV marketing is specific. Building a plan to grow to a million users organically is an order of magnitude more difficult than doing it with the aid of the LTV formula. There is comfort in its determinism, and it is simply easier to do.
Some people wield the LTV model as if they were Yoda with a light saber; “Look at this amazing weapon I know how to use!” Unfortunately, it is not that amazing, it’s not that unique to understand, and it is not a weapon, it’s a tool. Companies need a sustainable competitive advantage that is independent of their variable marketing campaigns. You can’t win a fight with a measuring tape.
