Problem
Interview Kickstart's referral channel was passive: ~50-60 leads a month from ~5,000 active learners, with incentives paid only on conversion. That left a $0 lead-gen CPL and no reason for advocates to create top-of-funnel volume against a $200 marketing CPL benchmark.
Metrics
- 1,925 referral leads in one campaign month: 35x the ~55 leads/month baseline
- Referral CPL ~$82.50 vs $200 overall marketing average
- ~6.3x program ROI; ~7x conversions vs the prior monthly baseline
Decisions
- Enable visibility and frictionless sharing before turning on volume incentives.
- Pay for qualified-lead volume, not only closed revenue, then automate gift-card ops so CS does not drown.
- Accept a lower conversion rate at 10x+ volume if unit economics still beat the $200 marketing CPL.
Outcomes
- Hybrid incentives: volume gift cards on qualified leads plus a lower conversion CPA ($800 vs $1,300).
- Shipped leaderboard, unique links, in-dashboard lead submit, SSA outreach, and Amazon Gift Card API payouts.
- One-month campaign: 35x leads, 10% lead-to-purchase conversion at the new volume, CPL well below paid marketing.
