What it is
Stripe checkout + Pass / All-Access tiers. First dollar.
Related — same category
Orchestra institutional tier. Bulk-invite, section grouping, conductor dashboard.
Teacher seat-pack tier. Studio dashboard, student insights, parent consent gated.
Founding Member tier: 20% off forever, capped at 100 seats. Live remaining-seats counter from Stripe coupon. Trumpet banner now drives the offer — biggest LTV lever per research.
Trial-countdown rebalancing. TrialCountdownHero was anchored to a 7-day trial mental model with hardcoded TRIAL_DAYS=7 + tier thresholds tuned to 7 days, but Mark LXXV had bumped TRIAL_DAYS to 14. Rebalanced thresholds (last_call ≤1, urgent ≤4, focus ≤9, encouraging ≥10) + updated 'Seven days' copy to 'Two weeks'. Real bug caught while auditing dashboard surfaces.
