KPIs — don't overthink it. A KPI's usefulness goes down proportional to the amount of time you spent thinking about it. The best ones are just like: how many people use the feature, how many dollars through the feature. If a KPI you need a PhD to design, you probably need at least a masters to understand it.
Simple KPIs Beat Complex Ones — If It Takes a PhD to Design, No One Will Use It
Complex KPIs look rigorous but fail in practice because no one except their creator understands them well enough to act on them. Taylor Wells observed teams designing elaborate composite metrics that were technically precise but practically ignored. The inverse: the KPIs that actually changed behavior at Disney+ were the ones a PM could explain in one sentence. Clarity of metric beats theoretical accuracy every time.
The magic of subscriptions is that if you do build something valuable you are creating a new annuity it's like if people are using it day in and day out they could be using it for a decade... you're not having to reacquire your users all over again like we did back in the paid up front days.
Subscriptions create an annuity — stop reacquiring users you already earned
Paid-upfront apps reset revenue to zero every year; subscriptions compound it. A user acquired in 2020 who still renews in 2025 cost one CAC for five years of revenue. That annuity math is why optimising retention always beats optimising acquisition, and why founders who grasp it build very different products than those who don't.
There's a play for whatever you're stuck on.
