I started AfterSeed because I was tired of reading startup growth advice that was either too theoretical or obviously written by someone who had never actually done the work. I wanted to write the newsletter I wished existed when I was figuring out growth for Drebbel and other early-stage AI startups. Something practical, specific, and short enough to read during a morning coffee.

What I didn't expect was that the newsletter itself would become one of the best growth channels I've ever built. Not just for building my own audience, but as a model I now recommend to almost every AI startup I work with. A newsletter, done right, is the highest-leverage content channel available to early-stage companies. Here's why, and exactly how I built AfterSeed from zero.

Why a Newsletter (And Why Now)

Social media algorithms change. SEO takes months. Paid acquisition gets more expensive every quarter. But an email list is yours. Nobody can throttle your reach. Nobody can change the algorithm and cut your distribution in half overnight. When someone gives you their email address, you have a direct line to their attention.

For AI startups specifically, a newsletter solves a critical problem: the education gap. Most of your potential customers don't fully understand what your product does or why they need it. A newsletter gives you a recurring opportunity to educate your market, build trust, and stay top of mind until the moment they're ready to buy.

This is the same principle behind good content marketing for AI startups, but with one key advantage: you own the distribution. Your blog post might rank on Google or it might not. Your LinkedIn post might get shown to your followers or it might not. Your newsletter lands in their inbox every single time.

The AfterSeed Origin: Starting from Zero

When I launched AfterSeed, I had no email list. Zero subscribers. I had a decent LinkedIn following from my work in growth marketing, but I'd never asked those people to subscribe to anything. Here's exactly what I did in the first 90 days.

Week 1-2: Define the Positioning

Before writing a single word, I spent two weeks figuring out what AfterSeed would actually be. Not "a newsletter about growth." That's not a positioning. I needed to answer three questions:

  • Who is this for? Founders and growth leads at post-seed AI startups. Not VCs. Not enterprise marketers. Not general startup enthusiasts. A specific person with a specific problem.
  • What will they get that they can't get elsewhere? Actionable growth tactics from someone who actually works with AI startups, not a journalist summarizing trends or a consultant selling frameworks.
  • What's the format commitment? One email per week. Under 1,000 words. One idea, explored in depth, with specific steps to implement. No roundups, no link dumps, no filler.

That clarity is everything. When someone asks "what's your newsletter about?" and your answer is crisp and specific, people self-select. The right readers subscribe. The wrong readers don't. Your open rates stay high because everyone on your list actually wants to be there.

Week 3-4: Write the First Five Issues Before Launching

This is the step most people skip, and it's the reason most newsletters die within the first month. I wrote five complete issues before telling a single person the newsletter existed. Here's why:

  • It proves to yourself that you can sustain it. If you can't write five issues, you definitely can't write fifty. Better to find that out before you make a public commitment.
  • It gives you a buffer. Life happens. Client emergencies happen. Having a backlog means you never miss a send, and consistency is the single most important factor in newsletter growth.
  • It sharpens your voice. Your first issue will sound different from your fifth. By the time you launch, your tone and format are dialed in.

Week 5-8: The Launch Sprint

I launched AfterSeed with a simple strategy: tell everyone I already knew, and give them a reason to share it. Here's the specific sequence:

  1. Personal outreach to 50 people. Not a mass email. Individual messages to founders, growth people, and operators I'd worked with. "I'm starting a newsletter about growth for AI startups. Here's the first issue. If it's useful, would you share it with one person who'd find it relevant?"
  2. LinkedIn announcement post. I shared the positioning, a preview of the first issue, and a link to subscribe. This single post drove about 40% of my initial subscribers.
  3. Cross-promotion with two other newsletters. I reached out to two people who ran newsletters for adjacent audiences (not competitors) and we each mentioned the other's newsletter in one issue. This was the highest-converting tactic in the entire launch.
  4. Added the newsletter CTA to my LinkedIn profile and every piece of content I published. Not aggressive. Just a consistent, visible link.

By the end of week 8, AfterSeed had a few hundred subscribers. Not a huge number. But the open rate was above 55%, which told me something important: the right people were subscribing, and they were actually reading.

The Growth System: What Actually Moves Subscriber Count

After the initial launch, growth comes from building systems, not running campaigns. Here are the channels that have consistently driven AfterSeed subscribers, ranked by effectiveness:

1. LinkedIn Content (The Engine)

Every week, I publish at least two LinkedIn posts that are related to but not identical to the newsletter content. Usually it's a key insight from the newsletter, expanded with a different angle or a fresh example. Every post ends with a soft CTA: "I write about this stuff every week in AfterSeed. Link in comments."

The key insight: your LinkedIn content and your newsletter should feed each other, not duplicate each other. If someone reads your LinkedIn post and then reads the newsletter issue on the same topic, they should get new value from each. LinkedIn gives the insight. The newsletter gives the implementation details.

2. Referral Loop (The Multiplier)

At the bottom of every AfterSeed issue, there's a simple line: "If you found this useful, forward it to one person who would too." That's it. No incentive program. No referral tiers. Just a direct ask. And it works because the content is genuinely specific enough that readers know exactly who in their network would benefit.

3. Guest Content and Cross-Promotion

I write guest posts for other newsletters about once a month. Not pitching AfterSeed directly, but writing genuinely useful content for their audience with a brief bio that mentions the newsletter. I also do newsletter swaps: I recommend someone else's newsletter, they recommend mine. The key is finding newsletters with overlapping but not identical audiences.

4. Blog SEO to Newsletter Conversion

This is the organic acquisition play. Every blog post on this site includes a newsletter CTA. People find the blog through search, read something useful, and a percentage of them want more. The blog is the top of funnel. The newsletter is the retention layer. They work together.

5. Community Presence

I'm active in several Slack groups and Discord communities where AI startup founders hang out. I don't promote the newsletter directly. I just answer questions, share insights, and have AfterSeed linked in my profile. When people find your advice helpful in a community and then discover you have a newsletter, the conversion rate is remarkably high because you've already demonstrated value.

This ties into a broader community-led growth approach that works for both personal brands and startup products.

The Content System: Making It Sustainable

The number one reason newsletters die is that the creator burns out. Writing weekly is hard. Writing weekly while running a business is harder. Here's the system that makes AfterSeed sustainable:

The Idea Bank

I keep a running list of newsletter topics in a simple notes app. Every time I have a conversation with a founder that surfaces an interesting problem, it goes on the list. Every time I see a pattern across multiple clients, it goes on the list. Every time I read something that triggers a reaction, it goes on the list. I never sit down to write without at least 20 potential topics queued up.

The Writing Block

I write every Tuesday morning from 8 to 10. Same time, same place, every week. No meetings. No Slack. No email. Just writing. Having a fixed block eliminates the "when will I find time to write" problem. You don't find time. You protect time.

The Format Template

Every AfterSeed issue follows roughly the same structure: open with a specific observation or story, explain why it matters, give the actionable framework, close with one concrete thing the reader can do this week. Having a template means I'm never staring at a blank page deciding on structure. I just fill in the structure with this week's idea.

The Batch Process

Once a month, I spend a half-day writing two or three issues ahead. This maintains the buffer and means I'm never scrambling to write something the day before it's supposed to send. Consistency beats quality in the long run, and batching is how you maintain consistency.

Metrics That Actually Matter

Most newsletter creators obsess over subscriber count. It's the most visible metric and the least important one. Here's what I actually track:

  • Open rate: Anything above 40% means your audience is engaged and your subject lines are working. Below 30%, something is off. Either your content isn't matching expectations or you're attracting the wrong subscribers.
  • Reply rate: The best signal of content quality. When readers reply to your newsletter with their own thoughts, questions, or experiences, you've written something that resonated. I aim for at least 5-10 replies per issue.
  • Forward rate: Most email platforms don't track this directly, but you can infer it from new subscriber spikes that correlate with specific issues. When an issue drives noticeably more sign-ups than average, it got forwarded.
  • Unsubscribe rate: Below 0.5% per issue is healthy. Above 1% consistently means there's a mismatch between what people expect and what you're delivering.
  • Downstream conversions: For me, this means inbound consulting inquiries that mention AfterSeed. For a startup, it's product sign-ups or demo requests from newsletter readers. This is the metric that justifies the time investment.

The Newsletter as a Growth Channel for Your Startup

Everything I've described above applies directly to AI startups building their own newsletters. The model is the same: pick a specific audience, deliver genuinely useful content on a consistent schedule, and build distribution through the channels where your audience already spends time.

The one thing I'd add for startups: your newsletter doesn't need to be about your product. It needs to be about the problem your product solves. If you're building AI for supply chain optimization, your newsletter should be about supply chain challenges, trends, and best practices. Your product is part of that story, not the whole story.

The startups that get this right build an audience that trusts them as an expert in the problem space. And when that audience needs a solution, they think of you first. That's the compounding advantage of a newsletter done right. It turns your marketing from an expense into an asset that appreciates over time.

A newsletter is the only marketing channel where your audience explicitly asks to hear from you. Treat that permission with respect and it will become your most valuable growth asset.

Start small. Be consistent. Write for the specific person you want to reach, not for everyone. And give it at least six months before you judge the results. The compounding takes time, but when it kicks in, there's nothing else like it.
