Morning Brew Founder Built a Claude Content Machine; HubSpot Maps AI Citation Formats

By InnovaAI Research2 min read

Alex Lieberman, founder of Morning Brew, has built a Claude-powered content system designed to generate ideas without running dry, while HubSpot research identifies the specific content formats most likely to earn citations in AI-generated search results. Together, these developments give content-focused agencies a concrete blueprint for retooling their production and optimization workflows.

Key Facts

01Morning Brew founder Alex Lieberman built a Claude-based content system focused on ideation, using AI as a structured thinking partner rather than a final writer.
02HubSpot research identifies specific content formats, including definitions, numbered lists, and theme-organized pieces, as most likely to earn AI search citations.
03Search Engine Journal cites data from late 2025 and early 2026 showing competitive pressure on agencies from AI content tools is accelerating.
04The Lieberman model separates AI-handled ideation and structuring from human-handled editorial voice, a division agencies can adopt directly.
05AI citation readiness is becoming a distinct layer of content optimization alongside traditional SEO.

Why It Matters

▶Content structure now influences AI model citation behavior, meaning poorly formatted pages can lose visibility even when they rank well in traditional search.
▶A repeatable, documented AI workflow, like Lieberman's Claude system, reduces quality variance across agency teams and makes scaling safer.
▶Clients will increasingly ask their agencies about AI search visibility; having a concrete audit process positions agencies ahead of that question.
▶The split between AI-assisted ideation and human editorial judgment gives agencies a clear answer to the question of what they offer that a client using ChatGPT directly cannot.

Agency Actions

Document which content production steps require editorial judgment and assign Claude or a comparable AI tool to the remaining mechanical steps, starting with brief generation and outline drafting.

medium effort

Audit one client's top 10 ranking pages against HubSpot's AI citation format criteria, checking for definitions, direct answers, and structured lists, then prioritize updates.

medium effort

Build a shared prompt library organized by content type, modeled on the repeatable system Lieberman developed for Morning Brew.
