That’s it for my collection of Substack growth data and figures.
Demand for non ad-based media models has been taking off. With newsletters leading the pack.
Substack is both riding and driving this growing trend.
In fact, major tech players are looking to get into the paid newsletter business as well.
Twitter recently introduced Revue integration to the platform to promote paid newsletters (following its earlier acquisition of the service) And Facebook launched Bulletin Substack-like tool designed to support independent writers.
So it will be interesting to see what’s coming next for Substack.
