A Sable challenge · 101 days

Reallocate after mature evidence

Register a multi-arm comparison, wait for the declared outcome lag, then deploy a supported arm to future prospects with a randomized holdout. The business is shifting toward multi-publication media groups while smaller writers still dominate the account count. 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.
