Great article! One question - The math doesn't work, does it? A 1.2% conversion ratio end-to-end for SaaS startups that don’t ask for a credit card in advance suggests that if we can get 1000 visitors, then we should expect 100 trial users, converting to 1 paid user. At least that’s the theory. I follow that the 1.2% is from the total visitors. 10% * 15% * 80% = 1.2%. So they should have expected 12 paid users per 1000 visitors. One question on the conclusion... Indeed Show HN seems to be a much better (more efficient) option for a good product. But how do you scale it? There are only so many communities you can find. Advertising can be much more easily scaled. If you want 100 more view, pays 100 more times the money. Or perhaps 50 times the money if you can get a volume discount.
