Probably not, given that he abandoned the app and works at Stripe now.

I learned the hard way that "passive income" via SaaS is fools game. Yes it does exist, but it's incredibly rare and so it's very unlikely that any idea I have is going to be the unicorn idea that generates a shedload of money for minimal effort.

I stand about as much chance of becoming the next YouTube/Insta star.

It might. He talks about revenue but not about profit. So we dpn't really know much about his costs, aside from him mentioning that he was spending a meaningful amount on insurance.

It could very well be that acquisition cost was quite reasonable, and he may have talked about this elsewhere. I just don't think the IH interview tells us enough to know for sure one way or the other.

He's published a huge amount of detail about revenue and costs, his profits aren't enough to sustain a family.

I say that with the greatest amount of respect for the man by the way, he's super super smart and I love his writing.

It can be great even if the "acquisition cost" is high, assuming you charge people for it.

It just doesn't lend itself to the "do a business that sells $10 dollar bills for $5 funded by VC money until it has enough eyeballs to start selling ads".
