Phase 3 north star. Informs every Phase 1 architectural decision.
Once MMA's paid membership crosses critical mass (estimated 2,000-5,000 paid members), the platform stops being a coach for retail buyers and becomes a wholesale aggregator. Synchronized group buys at LEGO B2B wholesale terms (40-50% off MSRP) deliver returns no individual flipper can match.
Individual investor at LEGO.com with optimal margin stacking: ~15-20% below MSRP. MMA Co-Op at LEGO Specialty Retail wholesale terms: 40-50% below MSRP. That 25-30 percentage point spread is permanent structural alpha — it doesn't disappear when more individuals discover LEGO investing.
More members → bigger group buys → better wholesale terms → better member margins → more members. The doctrine ensures the co-op only buys sets that actually perform, so the warehouse doesn't fill with duds. The community ensures trust.
Every architectural decision in Phase 1 needs to consider Phase 3 compatibility. Member identity needs KYC capability. Payment rails need escrowed/milestone support. Member relationships need to scale to a buying-club legal framework. Trust UI (transparency dashboards) is a Phase 1 requirement, not a Phase 3 add-on.
Buying-club vs securities offering classification. LEGO B2B account application requirements. 3PL vs in-house warehouse trade-offs. State-by-state sales tax obligations for a multi-jurisdiction group-buy operation. Escrow mechanics (trustee bank vs platform-held).
