Viral Loop Design
Engineer product-inherent sharing so each user brings >1 additional user — turning acquisition cost negative.
The Viral Coefficient
Viral coefficient k = invites sent per user × conversion rate. When k > 1, the loop compounds. Nimbus targets k = 1.2 by embedding share prompts at value-delivery moments — right after a successful injection or a clean fingerprint match.
Loop Architecture
- Trigger: User hits a milestone (first successful load, 7-day streak, license activation).
- Channel: Unique referral link with UTM-style tracking baked into the loader handshake.
- Reward: Extended license days or priority CDN tier — delivered instantly via KeyAuth webhook.
- Re-engagement: If invitee doesn't convert in 48h, send a signed reminder payload through the desktop client.
Measuring the Loop
Track cycle time (invite → activation) in Upstash KV with TTL-based expiry. A healthy loop closes in under 72 hours. If cycle time drifts above 96 hours, tighten the reward window or increase the incentive. Every cohort is graphed in the dashboard under Growth → Viral Funnel.
Nimbus default
The loader ships with a dormant referral module. Enable it from the dashboard toggle — no client update required. The module self-signs referral events with the existing Ed25519 keypair so attribution is cryptographically verifiable.
