Depth beats breadth: the number that predicts co-sell revenue isn’t how many sellers touch a partner once, it’s how many come back. Place yourself against an anonymized sample of real AWS Marketplace co-sell behavior from the Ground Truth study. Enter four numbers — the last tier (10+) falls out automatically. No form, nothing stored.

Source: Ground Truth study — WorkSpan telemetry, an anonymized sample of AWS Marketplace co-sell behavior (80 partners, 2022–2025). The full study spans 95 partners across Amazon, Microsoft and Google; its deep cut is the Amazon 2025 cohort (68 partners, 229,002 referrals, 5,709 active sellers). Company identities anonymized. Dormant (zero-transaction) sellers aren’t counted — this measures depth among active sellers. Your inputs stay in your browser.
