A Riff challenge · 101 days

Find a paying audience

Compare segment-specific reach while keeping every assigned prospect in the denominator. Expand the audience with paid value rather than the most signups. Creators arrive through educational content but many never connect a second channel. The founder is choosing between more acquisition and completing first-week activation. Keep at least 45% of opening paid customers through the closing window. Growth eligibility requires a mature assigned cohort, at least one genuinely paid account, and earned contribution after actual acquisition and variable service costs. No free-form pitch is scored.
