This is the most comprehensive guide to user acquisition I’ve ever read. Every founder, marketer, or early growth hire should know this stuff.

Hey everyone! Thanks for hunting, Alex. My goal with is to write handbooks that are exhaustive and insightful. That's a slightly obnoxious motto, right? But that's what excites me 😂 Trying to push myself to write something useful... So it made sense I finally got around to writing about growth. It's how I've been earning a living for the past three years. I started writing this handbook while I was on a startup consulting spree. I had a blast bouncing between startups so I could peek inside their operations, show them what to do, then move onto the next roller coaster. But when I decided to formalize my consulting into a proper agency, I put this handbook on hold for a couple months. Here's why: My new goal was to sign clients whose businesses would help me learn what I still hadn't mastered. So the remainder of this handbook began filling up with my calculated, on-the-job experiences. I wish I could write more handbooks with this method. Unifying my work (growth) with my passion (handbook writing) made this particularly enjoyable. Unfortunately, this probably won't happen again, as future handbook topics include playing piano and speaking Chinese 😂 I really hope all this material helps you kick ass with your startup.

Julian knows his stuff - he's one of the best growth marketers I have ever met. He's an excellent writer, and is a true full stack marketer who gets customer behavior, development & design. Must read for anyone running a startup/online biz
