How to define & manage your ICP?

After going through this topic numerous times myself and also discussing it with other founders/marketers, I've made a summary of how to manage your ICP. 1) For companies with already launched products (relying on 1st + 3rd party data), check: - The user retention over time, and connecting it with the users' profile - User engagement, and trying to find patterns within the user profile - Conversion, and link it to the user profile If all 3 aspects are pointing toward one specific user archetype, you struck gold :) For the majority of companies, conversion is the core, however sometimes VC-backed companies choose engagement & retention over conversion. With paying customers, managing the ICP is an ongoing job, that should be evaluated every 6 months or so. 2) For companies without launched products (mostly relying on 3rd party data), check: - Which profile is most common among website visitors - Which profile expressed the most interest on social media/forums - (If you conduct customer discovery interviews) Which profile is closest to buying or pre-ordering your product 1st party data = user properties, the data you've collected tracking your inside your app 3rd party data = user properties, the data you can check from LinkedIn & co How do you manage your ICP?
