These are the essential tools and setups I used to grow my publication from 0 to 3K+ subscribers and a Bestseller Badge in 6 months 🤗 They help you grow faster and work smarter. They cover the full stack: drafting and scheduling notes, audience insights, reader surveys, and email deliverability so your posts actually land in inboxes, not spam. With the right must-haves in place, you get clearer data on what’s working, tighter workflows, and higher ROI on every post you publish.

My real stack: the stuff that powers experiments, content, and products I ship via Product with Attitude. From AI and voiceover tools to VPN and user observability.

Everything you need: templates, tools, apps, gear and encouragement 🤗

My favorite mind-bending reads about who we are, how we got here, and why we build - history, anthropology, psychology, and the stories that shape us.
