I can attest to the brain-crackness. We're a bootstrapped startup that is starting to have a compelling product, and starting to think more about how to market it. We're definitely aware of the idea of lifecycle marketing and have been thinking about implementing it.

If purchasing this course lets us get a lifecycle marketing system going that is 10% more effective two weeks earlier than if we had to learn the lessons ourselves, it would pay for itself. Of course, if we had to smash our brains against it and try to pick out a cohesive strategy from across the internet it's very likely to take us a long time - months or years - to learn all the things in the course.

If you're in the target market for this product, and you know patio11 enough to trust him, the sales pitch boils down to "You give me several hundred dollars, and I'll give you thousands of dollars."

Haha, but even with that rational analysis done, the idea of spending that much on something pains my bootstrapping mind tremendously.
