Define success in plain numbers
Pick an anchor like monthly recurring revenue, active subscribers, or average order value that directly reflects customer trust. Add two or three supporting measures such as trial to paid conversion, activation time, or repeat purchase rate. Keep definitions unambiguous, documented, and easy to calculate. When everything is measurable and simple, you recover momentum after setbacks, explain priorities to collaborators, and avoid chasing vanity spikes that look exciting but leave the business unchanged.
