This is another great example (even an extreme one) that in software, a small team can build great things. But it's a good thing for society that most companies are not like this. Otherwise, many of us won't have jobs.
Build great things? Come on, it is a job board depending on network effect. I mean it seems fine and all but it is not a great thing.
Not sure how you define great, but as long as you provide a platform for people to find new opportunities and is quite successful for both parties, I'd say it's great and quite an achievement.
It provides value for many companies and people. It's very profitable. Hence it's great in my book. The founder also built NomandList (also mostly by himself I believe) which helps many nomads out there to socialize and connect. Both qualify as great things.
Thank you. And yes Nomad List is also 99.9% hand built by me.
