Author says “often” and the comments here are all “no! See $COMPANY!”
Folks, there’s nuance here. They didn’t say “…always make bad startup ideas.”
There could be much more interesting meat here: how many startups are based on “internal tools”? How many of those succeed (for some definition of success)?
The problem with even answering that question is that I think the numbers parallel how-many-startups-launched vs how-many-startups-succeed. And if they track pretty closely, then the headline thesis isn’t novel.
In any case, shouting “nuh uh! Slack!” doesn’t really contribute to the conversation.
