Founder-led community build
Serial Marketers (and its sibling, AI Marketers Guild) became the gathering place for senior marketers — built on word of mouth, premium events, and a newsletter clearing 50% open rates.

Most 'communities' are Slack groups with a churn problem. Serial Marketers was built to be the opposite: a high-trust network where senior marketers actually meet each other, swap real intel, and find work. AI Marketers Guild followed when generative AI rewrote the marketing playbook.
Build a community senior marketers actually show up for — without paid ads, without a 'creator' team, without sponsors driving the agenda. Make it valuable enough that people open every email and bring friends.
Treated community like a product, not a content channel. Distribution by trust + scarcity, not algorithms.
A LinkedIn post + Google Form. No ads, ever.
100+ virtual events plus a monthly NYC happy hour kept people coming back and bringing peers.
Productized the community with a paid layer; tested new offerings (job board, AI tools, partner intros) on a tight cadence.
When generative AI changed the brief, launched a sibling community focused entirely on senior AI-marketer practice.
A real network — and a distribution channel that pays compounding returns across every other High Caliber AI offering.
AI Marketers Guild is a senior-marketer community focused on practical applied AI — a sibling to Serial Marketers, both founded by David Berkowitz.
5,000+ combined members across Serial Marketers and AI Marketers Guild community, with ~50% average weekly newsletter open rate.
Word of mouth, PR, and event partnerships — zero paid ads. Events are the loyalty loop; the newsletter is the distribution.
After years running fractional CMO engagements, the gap was obvious: clients needed something lighter than a fractional but more accountable than a favor. FOAF.pro filled it.
