re: "The next big question is: Can you scale it ?" I would like to suggest a potentially more interesting question (or set of questions) : _Should_ he scale it? If so, why? Why would so many HNers assume the next step to be scaling it? Might he not instead tend to his business like a garden, to ensure that it continues to be healthy, and use his remaining time to enjoy semi-retirement? I think a lot of HNers could do…
Because having just one stream of income, no matter how reliable it seems is a huge risk. Before you know it you can be back in the treadmill again.
Perhaps I should also have mentioned that he is diversifying, where diversifying is certainly distinct from scaling the first business up.
As far as his first business goes, I still think it is worthwhile questioning the common automatic assumption that the next goal should be to scale it.
