Awesome! As a marketer-product-growth person, I wish projects like these were more common among marketers. With my "people" every good resource is a for profit endeavor and is paywalled lol. Does anybody possibly know some awesome resource like this but for marketing-product-growth? I was thinking about working on a something like this for growth principles and notion templates for SaaS. Just not sure the 100+ hours on that would be worth, if anyone would use it.
