Documented cause
Brainly's paid subscription tier, launched aggressively in 2020 with $80M Series D from Naspers, failed to convert its 350M free users. Premium churn exceeded 70% within 90 days as students found free workarounds. By Q3 2022 Brainly laid off 25% of staff and killed the premium product, reverting to ad-supported model.
Lesson
“A massive free user base is not a monetization asset if the value proposition doesn't justify switching.”
