$10K MRR on $12 panic passes: the AI coach that skipped subscriptions

$10K MRR in seven months. Solo founder, no audience, no team, one bootstrapped AI interview coach at trycontrol.app. Most readers will file this as "another AI wrapper win." It's something stranger. The majority of revenue comes from $12 and $19 one-time passes bought by people whose interview is tomorrow. The operator thinks the instability is his biggest problem. It's actually the entire moat, and he hasn't noticed yet.
