IANAA (I am not an actuary) but surely this can't be the entire computation. Death is only one reason a solo SaaS might fail. The real problem is mental noise, and the fact that large organizations have the positive side-effect of averaging out that noise to produce coherent, predictable actions. (The humanist wants to point out the "noise" is sentiment, artistry, beauty, and the coherent behavior is that of a profit-driven sociopath, but the point stands.)
What I'm saying is that their chance of death is .2% but their chance of discovering Buddha, deciding to give up everything and become a monk, or meeting the woman of their dreams and going to live the simple life in Thailand, and so on, are much, much greater.
I don't think one needs to be an actuary to appreciate that comparing the mortality rate of solo founders with the failure rate of VC backed companies doesn't make sense.
When he is asked to defend it, he clarifies that he's only talking about companies that solve a major pain point, have no other competitors, and a low cost of implementation. (Obviously the failure rate of VC-backed companies with amazing PMF and amazing operating margins is much lower than 30%!)
His comment is the highest voted in this thread (assuming HN sorts that way) -- this is a classic example of 'this person says something I want to believe and has some numbers so I'll upvote it without even a rudimentary interrogation!'
