Eh, I think this is spurious. The specific post you're replying to is about a signal that seed funders can use to predict if founders have what it takes.
Seed funders can't really use the signal of "did they get VC money?"
Also, technical proof of concept is definitely a positive signal, but is not at all sufficient to make a reasonable investment bet.
That's a fair point, but my point was really: if they can convince you as an investor to actually put in money, then they certainly have sales skills that outclass those of acquiring some random co-founder. Admittedly, maybe they don't have the technical skills, or perhaps you as an investor lacks the specific skills to evaluate those in the way that a potential co-founder might be able to, but (as I mentioned) that's what technical due diligence is for anyway.

I don't see what you are saying. Are you saying that getting a co-founder is more sufficient than a technical proof of concept to make a reasonable investment bet? I wasn't arguing that one should make an entire investment based solely on one factor (the product itself).
My point is simply that: being able to sell a co-founder on the idea or product seems to be an easier lift than selling an investor to invest real money in the idea or product, irrespective of other factors.
If you are able to recruit founders to work with each other, you didn't prove anything that couldn't be just as easily proven by recruiting a VC to invest in you.
And if it's not sales/hype that we're trying to prove, but instead a technical review by a potential co-founder, then that's what technical due diligence is for.
To me, a much better test is whether or not they've managed to get a believable proof of concept or even actual traction all by themselves, without any help and without even a co-founder.
That is a much better proof point. (leaving out of the discussion other salient points like market size, growth rate, etc)
Being able to attract another idiot who might not know anything at all about the problem domain, or gets excited about it for a few weeks or months, or "joins" five different startups in six months in the hopes that one of them gets funded.. this proves nothing of value.
Convincing a VC to fund you at reasonable terms? Much harder than finding a pliant co-founder if you have even mediocre skills at marketing/sales.
The real reasons VC's want multiple founders aren't really talked about, because they're not flattering to VC's: https://news.ycombinator.com/item?id=18924243
