I build content systems with Claude that research, write, verify, and ship.

I’m Bret Kerr. I spent a decade at Mimecast building its video and creative capability through IPO and take-private. This site is my working proof: every page, pipeline, and gate on it was designed by me and built with Claude Code.

How I can help

01 · Build

Content systems that ship themselves

I design and build the pipeline: research, drafting, adversarial review, verification gates, and publishing. Your team gets the system and the runbook, along with the first batch of content.

02 · Explain

Interactive explainers for technical products

Dense papers, architectures, and product launches turned into runnable, source-anchored pages that buyers and researchers actually finish.

Run the Transformer Atlas →

03 · Enable

Claude Code workshops & advisory

Hands-on sessions for marketing, content, and GTM teams: skills, subagents, multi-model research loops, and how to keep agent output trustworthy.

How it’s built

Agents propose. Gates dispose.

01 · Research
Opposed deep-research briefs (Gemini as cartographer, GPT as adversary), then cite-checked and reconciled.
02 · Build
Claude Code writes the pages, pipelines, and tests, guided by reusable skills I maintain.
03 · Verify
Deterministic gates, not model consensus, decide what ships. Quotes are verified, numbers are recomputed, and goldens are locked.
04 · Ship
One operator. Cloudflare Workers, a parity-gated deploy, and a public commit history.
