Amy Hoy has spoken a lot about this. I think we're about to see a wave of new startups that focus first on info-products that involve blogs at some stage, then later pivoting into a SaaS product.<p>This is exactly what I'm doing right now. Everything works as one big marketing funnel from tweets/pins/posts to free downloadable content and one-off landing pages, to single page apps, to e-books and videos, all the way up to SaaS. I have to come to love the term Amy uses for these: e-bombs. Finding customer pains and dropping e-bombs on them is a really lean way to learn a ton quickly, build an audience, and even make money.<p>If you get really good, you can make it into a repeatable process that works over and over regardless of your domain experience. That said, I still think it might be a little difficult for me to do this for, say, theoretical physicists. I'm personally inclined to partner up with domain experts rather than trying to do it all myself as a lone technologist.<p>Great examples in the post. Now let's see some more! I've seen Moz and 37signals mentioned. Who else are we missing?
