If company B should end with the same result as Company A after 12 months they should acquire 154 new subscribers each month. More than 50% more than company A.
I am not going to give you a finite answer to the question I initiated this post with – however I encourage you to reflect what you think is easier and requires less resources. A socalled “low hanging fruit”
Acquistion of 50% more subscribers every month OR retaining 10% (in full numbers) more subscribers every month.
My recommendation is usually that if you focus on keeping your new acquired customers happy you will end up with a more profitable business than if you focus solely on acquiring new customers every month and thus tend to neglect existing customers.
Even small variations will give you a big difference after 12 months.
