Growing an AI newsletter to 2 million subscribers in two years

Executive overview

The AI content space is flooded with noise. The Rundown AI grew to 2M subscribers by doing the opposite of competitors: staying human, going vertical, and treating the newsletter as a distribution asset first.

Human-generated content with a clear niche beats AI-generated content at scale — for now.

Why human content wins

• AI-generated newsletters lack soul; readers can detect them
• Content will split into two tiers: Walmart (AI-generated, cheap, addictive) and Whole Foods (human, trusted, influential)
• The 1% who stay human will have disproportionate reach and brand value
• Everything in the middle dies

Going vertical as a content creator

• Everyone talks about verticalized AI SaaS (AI for law, accounting) — nobody talks about verticalized content
• Niche content is blue ocean; an "AI for law" content creator doesn't exist yet
• Broad creators have distribution and audience data; niched creators have less competition

Getting started: writing vs. talking

• Ask yourself first: do you prefer writing or talking?
• Writers: start on Twitter — research, demos, and papers often publish there first
• Talkers: record raw ideas on a walk using a transcription tool (e.g., Whisper Flow), then feed the transcript into a Claude project trained on your best posts
• This workflow converts raw human thought into a 90%-ready draft without generating AI ideas

Building the newsletter

• Starting an email list converts social virality into a durable business asset
• Near 50% open rate at 2M+ subscribers — achieved by human takes, not AI copy
• Use AI for structuring and research; never for the human voice or perspective
• Put faces behind the brand to signal authenticity

Scaling to video without showing up

• Audience demanded video; founder had no time
• Solution: clone face and voice with AI avatar, use real writing as the script, add B-roll and editing
• Instagram grew to 160K followers in one year from this workflow
• Hook length varies by platform: LinkedIn = 2 lines, Twitter = 3 lines, Instagram = 1 line

Building AI intuition at work

Three habits to become an early AI adopter:

1. Ask daily: "Could AI do this task?" — write it on a sticky note on your screen
2. When the answer is yes, find the best tool and spend a few hours testing it — failure teaches you AI's limits
3. Share what you learn (with your team, friends, or publicly) — sharing accelerates learning and builds your reputation

The age of the idea person

• Founders who combine distribution, audience data, and AI capabilities are uniquely positioned
• Content creators could become the next billionaires — they already influenced elections
• Capabilities are growing fast; if you have an interesting idea, build it now
