I would also invest 100k-1mi in a company that's growing 10% month-to-month and had 10k+ paying users.

No companies in such position should need to raise that amount money. It's not completely useless, but: you can't hire talented developers with it, you could spend cash with office and 'stuff'... My point is, if you are profitable, raise 20mi, 10mi. 100k won't make much difference.

Maybe you want to work specifically with Ferriss, but the truth is, profitable startups are in high demand (because there are none) and they are the ones choosing partners.
