One of the key jobs of the CEO is to decide when to hit the accelerator pedal. The value of these two guidelines is that they help you understand when you have a SaaS business that is in good shape, where it makes sense to hit the accelerator pedal. Alternatively if your business doesn’t meet the guidelines, it is a good indicator that there is more tweaking needed to fix the business before you should expand.
Another way to use the two guidelines is for evaluating different lead sources. Different lead sources (e.g. Google AdWords, TV, Radio, etc.) have different costs associated with them. The guidelines help you understand if some of the more expensive lead generation options make financial sense. If they meet these guidelines, it makes sense to hit the accelerator on those sources (assuming you have the cash).Using the second guideline, and working backwards, we can tell that if we are getting paid $500 per month, we can afford to spend up to 12x that amount (i.e. $6,000) on acquiring the customer. If we’re spending less than that, you can afford to be more aggressive and spend more in marketing or sales.
There is another important way to use this type of guideline: segmentation. Early-stage companies are often testing their offering with several different uses/types of customers / pricing models / industry verticals. It is very useful to examine which segments show the quickest return or highest LTV to CAC in order to understand which will be the most profitable to pursue.
