Back in 2021 I guessed that Shopify was overvalued because it didn't benefit from the same network effect that Amazon benefits from. (Also I preregistered this prediction so you know I'm telling the truth lol no I didn't.) Shopify has an app that app lets users buy from web stores that are Shopify built if they have the address. This difference is reflected in the size and staying power of their B2B customer base.
