One-liner: A tightly-scoped newsletter/YouTube channel analyzing pro matches through the “percentage tennis” shot-selection lens (same methodology behind courtiq), monetized via a low-ticket subscription ($10-20/mo) and used to build an audience to funnel into the app and course.
Origin: Brainstormed 2026-09-23 in a session about hitting $250K/year solo online, tennis+fitness passion angle.
The core insight: Slowest-money option of the batch, but it’s the one that builds a durable audience rather than depending entirely on B2B outbound sales. Content compounds over time and gives CourtIQ and the percentage-tennis course a warm audience instead of a cold-outreach motion.
Status: Raw — unvalidated, no content produced, no audience yet.
Open question: Worth starting now as a slow-burn compounding asset, or premature until CourtIQ/the course have something concrete to funnel readers toward?
