Highlights
I’ve seen hundreds of decks, cohort analyses, and retention reports from consumer social companies over the past decade.
High growth. Explosive engagement. Incredible early retention curves. Social proof so strong you start believing the product is unbreakable.
And then, most of the time, it fades.
People move on. They get distracted. The hot new thing becomes yesterday’s app. Very few products earn a permanent place on someone’s home screen, let alone in their habits or identity.
Some user churn is normal. Every consumer product loses some of their users over time. But the truly exceptional products are different. At some point, the users who left start coming back.
They fall back in love with the product, with the fact that it serves an inherent need.
And after hundreds of graphs and reports over the years, this is the first time I’ve seen something this extreme happening simultaneously:
-
insane product and distribution velocity, and the growth that comes with it !
-
retention curves bending back upward !
Meaning: over time, some cohorts stop decaying and begin strengthening again because returning users outweigh the users still churning from that same cohort.
That’s extraordinarily rare. That is @amoamoamo.
Insane Ambition, Huge Heart... Something rare in our world !
