Documented cause
Blab, a live video conversation platform used heavily by marketers and content creators, shut down in August 2016 just 14 months after launch. Co-founder Shaan Puri announced the closure on Medium, citing that the product had failed to find a focused use case. Facebook Live's aggressive push in early 2016 crushed Blab's growth curve. Despite early buzz among marketing thought leaders, daily active users collapsed 70% from peak in under six months.
Lesson
“Live video platforms need defensible niches before Facebook clones them into oblivion.”
