My biggest question now is - since now anyone can build a SaaS, and since everything is now optimized not for "employment" but for "enterprise" (run your own business), just how many 1-2 person companies can we build? I mean how many genuine sell-able ideas are there. Can we as a society have a 100,000s small software enterprises (and not a few hundred employing 1000s)?

I would love to start my own SaaS company, even if it generates $1000 a month I will be elated. And I have 20+ years of experience programming and in FinTech, but what do I build? Not to mention, without sales & marketing nothing will really work.

Two of the startups are lead by non-technical founders who have strong industry specific experience (legal and finance). The third has a partner that has industry experience (is the ICP).

So you definitely still need strong sales and marketing and a deep understanding of a business domain.

1 person and AI is not sufficient to create a business.
