Concrete case: one personal-development product that generated repeatable revenue — share format, price, channel, and one metric

For creators, coaches, and practitioners: please share one specific launch or product that reliably made revenue from personal-development work. Keep to a single example per post and give first-hand, verifiable details where possible.

Include these fields:
- Product name / 1-line description
- Format (e.g., self-study course, cohort program, monthly membership, 1:1 coaching, workshop, app)
- Price (typical price per customer or subscription)
- Audience size at launch or funnel size (email list, followers, warm leads)
- Acquisition channel(s) and main tactic (e.g., organic Instagram ads, paid Meta cold traffic -> webinar, partnerships)
- One metric that proves repeatability (conversion rate, CAC, LTV, MRR, churn, cohort retention, repeat purchase rate)
- One major barrier you hit and how (if at all) you handled it
- What you would pay for in a community to replicate this result (specific features, templates, feedback, experiments, verification tools, etc.)

Optional: share a link or screenshot (anonymized numbers ok). Please speak from your own experience — do not post hearsay. This is for practical playbooks and repeatable tactics, not general opinions.
