Rule of X
A growth-weighted efficiency benchmark that credits revenue growth more heavily than profit, an evolution of the Rule of 40 for growth-stage software.
The fork, why two teams get different numbers
Where the Rule of 40 adds growth and margin one-for-one, the Rule of X multiplies growth by a weight (commonly around 2) before adding free-cash-flow margin, on the thesis that a point of durable growth is worth more than a point of current margin.
