I was thinking about network effects, where every additional user you gain makes your entire service more valuable to everyone involved (increasing customer lock-in and widening the moat new competitors must cross to attack you).
It led me to these 8 business model patterns. Some network effect businesses use most of them. Others use just one or two. I don’t have a big conclusion to make, but I wanted to share my thinking in case it’s useful. I’ve had a couple useful breakthroughs by comparing my ideas against these 8 patterns to see what I might be able to change to reach a more defensible model.
