Oisín O. — I used to do a lot of behavioral optimization for digital products, especially around revenue and other key behaviors. The tools I most often saw in use were Mixpanel, Pendo, and Amplitude.
Related to your question — in most cases, we were the ones recommending that teams use behavioral data (not demographics) to build cohorts for improving resubscription, cross-sell, and upsell performance.
Why that didn’t happen by default:
They usually lacked the behavioral expertise to identify which dimensions mattered for cohort creation, and how those insights should inform messaging and strategy
In many cases, setting up the tools properly to track meaningful behavioral signals was too difficult, so teams defaulted to what they already knew or could implement quickly
In essence: they lacked clarity on what actually needed to be tracked, and the capability to configure their tools to track it.
Hope that helps!
