Wilco de Kreij – GrowOS

GrowOS is Wilco de Kreij’s training and workflow package for marketers using Claude Code to handle recurring content and marketing operations. It brings together more than thirty prepared workflows for creating assets, conducting research and moving work toward publication.

The material covers both running the prepared system and describing custom workflows in plain English. It also addresses the practical role of human judgment when automated content and connected accounts are involved.

What you’ll learn

• Use prepared AI marketing workflows for recurring content creation and marketing operations
• Create newsletters and social content for Twitter, LinkedIn and Facebook
• Produce Facebook advertisements with AI-generated images
• Edit videos with subtitles, cuts and animations
• Build custom workflows in plain English without writing code or using external automation platforms
• Connect email platforms, social schedulers and advertising accounts for publishing and scheduling

Run the System with Claude Code

The Run the System track uses video walkthroughs that begin with Claude basics and progress to publishing a first newsletter. Demonstrations and troubleshooting show how the prepared workflows fit into recurring marketing tasks.

A shared voice profile and feedback loop are intended to help keep output consistent across channels. Those tools can support an editorial process, although consistent wording does not establish that a claim is accurate.

Content, advertising and video workflows

GrowOS covers newsletters and social content for Twitter, LinkedIn and Facebook, alongside landing pages, sales pages, carousels and thumbnails. Research and planning workflows support the work that precedes content production.

The package also addresses Facebook advertisements with AI-generated images and mechanical video editing, including subtitles, cuts and animations. These workflows apply automation to different asset formats rather than limiting it to written drafts.

Automate Anything and publishing connections

The Automate Anything track teaches users to describe custom workflows in plain English, without writing code or using a separate automation platform. It extends the prepared system to recurring tasks that a marketer or team wants to define.

The workflows can connect with email platforms, social schedulers and advertising accounts for publishing and scheduling. Because connected tools can take actions beyond drafting, account permissions and human approval remain important parts of the process.

Team Operations and the AI Stack

The Team Operations bonus addresses assistants, permissions and handoffs, and includes customer implementation examples. Its focus is how workflow activity can be organized across a team rather than treated as an isolated content task.

The AI Stack material includes a breakdown of monthly operating costs, without specifying an amount. GrowOS depends on Claude Code, whose subscription, limits and product changes affect the workflows.

What’s in the course files

The course files include videos and PDFs, alongside the prepared marketing workflow material. The video instruction includes walkthroughs, demonstrations and troubleshooting for using the system.

The package also includes the Team Operations and AI Stack material, covering team handoffs and operating costs. Together, these resources address both content production and the tools needed to run it.

Who GrowOS is for

GrowOS is for marketers and teams who want to use Claude Code for repeatable content production, research and publishing operations. It is especially relevant to those interested in adapting workflows without coding.

The material suits an approach in which people review factual claims and retain responsibility for publication, while automation handles repeatable production and routing tasks.
