I am joining now. What do I actually get?
The full course $899: all 9 modules live now, lifetime access, certificate, and private Discord. A standard 14-day refund from purchase applies.
Is the price still going to change?
No. All nine modules are live and $899 is the full price. Anyone who bought earlier keeps every module, no upsell.
Is there a seat cap?
No. There is no seat cap at any tier, buy as a team if you like. The only thing ever limited was the founding 1:1s, the first 20 founding buyers, and the founding tier closed on 14th of June.
What is the refund policy?
A standard 14-day refund window from purchase, no questions, no forms, just email.
Can I get my company to pay for it?
Yes, and most learners do. This is professional training, so it usually goes through a learning and development or team budget, and plenty of people get it approved even without a formal one. The "Ask your company to pay for you" section above has a ready-to-send email template: copy it, fill in the brackets, and send it to your manager.
When do the modules ship?
Five modules go live on 15th of June: Agentic Foundations, Agentic EDA, Building MMMs with an Agent, Bayesian MMMs in Meridian, and Experimentation with an Agent. The final four — Attribution, Calibration & Triangulation, Evals, and Reusable Team Workflows — ship on 15th of July. Both dates are public, so you can hold the calendar to this page.
Why ship in two drops instead of all at once?
Two reasons. Honest one: it lets the product start delivering sooner instead of waiting for everything to be recorded. Pedagogical one: most learners cannot consume ten hours of dense MMM video in one weekend. The split lets you apply the first five modules on your own data before the rest land.
What does the price do over time?
$899, the full price now that all nine modules are live. Earlier buyers keep every module they were promised, no upsell email.
Do I need to know MMM already?
Yes. This course assumes you have built a Marketing Mix Model before, or at least know what adstock, saturation, contribution, and DECOMP.RSSD mean. If you do not, start with Gui’s live Marketing Science Bootcamp on Maven first.
Do I need a paid subscription to Claude Code, Codex, or pi.dev?
You need access to at least one of them to follow along. The course shows how to set up project instructions for all three so you can pick the harness that fits your workflow and budget. None of the three are bundled with the course.
How do I know the agent is not making things up?
Every module ships with a self-grading harness for the agent’s output and a seven-question validation checklist you can rerun manually. The validation habit is the spine of the course, not an afterthought — module 08 turns it into automated evals.
Will this work with my data?
The course uses a synthetic multi-geo marketing dataset that mirrors the shape of real spend, revenue, and seasonality data. Practitioner-scenario exercises include messy variants so you have practice before you point an agent at your own data.
