Substack Growth Hub: Everything I’ve Learned About Growing on Substack —Notes, Niche, and 10x Growth Patterns
The chronological journey from zero to now, with every article I wrote at each stage. No retrospective polish.
Last updated: April 2026
I’ve been on Substack for 18 months now. Started with zero audience, zero niche, zero clue.
Today (April, 2026): 6,000+ subscribers and 200+ paid, while holding a full-time job and raising two toddlers. This page is the chronological version of how that happened, with every article I wrote at the stage I was actually in. Find where you are below and start there.
Hi, I’m Jenny 👋
I write about turning friction into launched AI systems, and a lot of that journey ran through Substack. Everything below is tested on my own newsletter, not borrowed from someone else’s playbook.
This is the Substack Hub, other hubs you might also enjoy:
Claude Hub · Vibe Coding · AI Agents · Shipped Products
What’s inside:
When I was starting from zero — the first 4 months, finding niche and format with zero proof anything would work
When I went paid for the first time — what I learned the year I crossed 1,000 subscribers and opened paid: data on 1,200 newsletters, the Rising Badge reality check, and the Notes system that scaled
When I crossed 4,000 subscribers in year one — the year-end retrospective: 7 mistakes that cost me subscribers, what actually moved the needle, what I’d do today
Where I am now (6,000 subs, 200 paid) — the current systems, with AI as the difference that makes growth sustainable on limited time
What you can actually do (if you skipped the journey) — three lever-based routes for the intent reader:
The full playbook from zero → 2 anchor articles
How to figure out your niche → 3 niche-research pieces
How to grow with Substack Notes → 2 Notes pieces
When I was starting from zero
Months 1 to 4. Zero subscribers to a few hundred. No clear niche, no committed format, no proof anything would work.
What I was actually trying to figure out:
Was there even a niche I could grow in, or was AI/Substack already saturated?
What format would I commit to, given I came from Medium with no audience there either?
Was the time investment going to be worth it?
I built a Python tool to research the niche, then wrote about what I found. The articles below are the artifacts of that figuring-out phase. Take the data seriously. Take the conclusions with the caveat that I was a tiny account with a lot to learn.
Was there a niche I could grow in?
I worked with an AI agent to crunch the numbers on 1,200 Substack newsletters in the AI niche. The findings: where I stood, where the gaps were, and what it actually takes to grow in a crowded space.
Written when I had under 500 subscribers and was genuinely scared the niche was already taken. The data said otherwise. That conclusion held up over the next year.

How I built the niche analyzer (and you can too)
The Python + Cursor build log for the tool I used to do the niche research above. Includes the Vercel API bug that broke it on deploy and the fix that took longer than the build itself.
Written for builders who want the tool, not just the conclusions. If you’d rather analyze your own niche than read about mine, this is the one.

What four months on Substack actually felt like
Three product launches, the first paid earnings, and the mental shift from writer-state to builder-state. The stage where I figured out what this newsletter was actually about.
Written at the four-month mark, before I had any growth proof. Useful as a vibe check if you’re in months 1 to 4 right now and wondering if it’ll ever click.

When I went paid for the first time
Months 5 to 8. A few hundred subscribers to about 1,000. Opened a paid tier and got the first paid subscriber.
What I was figuring out:
What actually moves the needle on Substack: Notes, recommendations, or article SEO?
What deserves to go behind a paywall, versus what should stay free for the algorithm and search?
Is the Rising Badge a real signal of growth or a vanity dopamine hit?
The pieces below are from when I had real data for the first time. Less guesswork. The Notes framework is paid because it’s the system I’d built and was actively running on my own account.
What 3,000+ articles by top AI writers reveal
A pattern study across 3,000 articles from the top AI writers on Substack. Writing patterns, format choices, what’s converging and what’s diverging across the niche.
Written when I was trying to model myself on the writers I admired and figure out what they were actually doing. Half the patterns I expected weren’t there. The half I didn’t expect to see, were.

What the Rising Badge actually means (and what it doesn’t)
Two months on Substack, two Rising Badges, and the panic that no one warns you about. The reality check on what the badge actually signals, what it definitely doesn’t, and how it can mess with your decision-making if you let it.
Written right after the second badge, when I was supposed to be celebrating but was actually freaking out. The most honest piece in this hub about how growth signals can scramble your head.

The Viral Substack Notes system
The full framework for writing Notes that capture attention, drive engagement, and convert to subscribers. Hook templates, content patterns, AI prompts, and a Notion package for automation.
Written when Notes were converting around 30% of my new subscribers and I’d built a system to scale it. Where the Notes implementation detail lives.

When I crossed 4,000 subscribers in year one
Month 12. 4,500 subscribers in one calendar year, mostly free with a small paid base.
This is the retrospective I wrote at the one-year mark, looking back at what worked and what cost me. It’s the most-read piece in this hub and the right place to start if you want one tactical guide instead of the whole journey.
How I grew from zero to 4,500 subscribers in one year
The retrospective. 7 mistakes that cost me subscribers, what actually moved the needle, and the growth tactics I’d use if starting over today. The single most-read piece in this hub.
Written at the one-year mark with enough data to look back honestly. If you read only one article from this hub, read this one.

Where I am now (6,000 subs, 200 paid)
Months 13 to 18. 6,000+ subscribers. 200+ paid in under a year of having paid open. Still a full-time job. Still two toddlers.
What changed at this stage: AI became the system that made everything else work. Not for writing the newsletter itself, but for everything around it. Research, Notes generation, niche tracking, distribution, repurposing. The articles below are the systems I’m running right now, and the paid piece is the most current snapshot of how it all fits together.
What 3,000 Notes from 9 creators show (and the MCP I built to study them)
The custom MCP for Claude Code that pulled and analyzed 3,000 Notes from 9 AI creators I wanted to study. Five data-backed patterns, plus the surprise: the most-posted Note format turns out to be the worst performer.
Written after I built the tool because I was tired of guessing what works. If you’re a builder who wants to research Substack programmatically, the MCP is open and ready to use.

What makes this hub different
Who is this for?
Substack writers who already have a newsletter (free or paid) and want to grow it without quitting their day job. Especially: AI builders, technical writers, knowledge workers, and people with kids or limited evening hours. Whether you’re at 50 subscribers or 5,000, every article below maps to a specific stage of the journey.
How is this different from the standard Substack growth advice?
Most Substack growth advice tells you to engage four hours a day, write Notes constantly, and exchange recommendations with everyone. That works if you have the time. This hub is the version that worked for me with a full-time job and two toddlers: 6,000 subscribers and 200+ paid in 18 months, with AI doing the heavy lifting on research, Notes, and distribution. Every article is tested on my own newsletter, not borrowed from someone else’s playbook.
How often is this hub updated?
New articles get added here as I publish them. The “Last updated” line at the top reflects the most recent change. Currently 9 guides covering the four stages of growth, plus a tactical lever section for readers who skipped the journey.
This hub started with the niche-analysis piece in February 2025 and grew into the chronological map of how I went from zero to 6,000 subscribers in 18 months. Every guide is written from the stage I was actually in when I wrote it. No retrospective polish.
The path through this hub
Stage 1 (figuring out the niche) → Stage 2 (going paid) → Stage 3 (the year-one retrospective) → Stage 4 (where I am now, with AI doing the heavy lifting).
Every article above fits somewhere on that path. Start wherever you are.
