Places to learn about CAC and distribution (I will not promote)

I’m a developer and I’m building a project management tool outside my day job based on the industry I work in. I’ve been following this subreddit for a while and most successful founders talk about distribution being a major factor in their success beyond product market fit. It’s not something I have much experience of but happy to test a few things out. What are some of the best resources people have found to learn about distribution and customer acquisition? Sounds like I’ve got a lot to learn! submitted
