1. Our Products and Services

We offer digital educational products and services at the following tiers:

TierWhat You GetPrice
DIY CourseThe whole system, all three parts (12 modules): the full self-paced course, framework teachings, Repo(sitory), and self-hosting guide, as a downloadable Repo(sitory) you own and keep. Lifetime access to the course; build at your own pace. No live sessions or library (those are Membership).EUR 550 (one-time)
The Four Languages MembershipMonthly membership for the live sessions on top of the course: four live calls a month (two co-build sessions and two AMA or Q&A calls), access to the growing Build Library of past co-builds, and Discord community access. Does not include the course (that is DIY). If the membership ends, the member keeps any files they have already downloaded; the live calls, the Build Library, and Discord access end with the membership.EUR 125/month

Scope is written down before the build starts, and anything outside it is a separately priced change order. Deliverables and all logins are handed over at completion and are the customer's to keep. Two rounds of revisions per deliverable. One business per engagement.From EUR 1,500, up to EUR 4,000 by scope (one-time)

Includes the DIY Course. What is completed within the agreed window is what is delivered. Excludes anything outside the agreed component list, copywriting, brand or logo design, and open-ended revisions. Deliverables and all logins are handed over at completion. One business per engagement.From EUR 9,000 (one-time, quoted per build)
