## 24. Summary & Implementation Priorities

*For detailed tactical roadmap with monthly milestones, see [28_project_roadmap.md](28_project_roadmap.md)*  
*For high-level prototype roadmap with phase breakdowns, see [24_prototype_roadmap.md](24_prototype_roadmap.md)*

### Lessons Learned Integration

**Critical Findings from 30+ Platform Analysis** (See [Section 30](../concept/30_lessons_learned_application_analysis.md) for full analysis):

1. **Critical Mass Requirements**: 50+ participants required (not 20-50) for meaningful network effects
2. **Local Clustering**: ≥70% participants within 5km radius (40% higher match rates)
3. **Data Quality Strategy**: Progressive refinement with scoring and incentives (prevents "data quality death spiral")
4. **Hybrid Automation**: 80% automated matches, 20% facilitated (prevents "facilitation dependency")
5. **Geographic Expansion**: Must achieve 50+ participants AND ≥20% match rate before expanding (prevents "geographic overreach")

### Implementation Priority

1. **Critical for MVP** (Revised based on lessons learned): 
   - ADR framework
   - Go 1.25 stack setup (Gin/Fiber, Neo4j driver, NATS/Redis Streams)
   - Basic caching (Redis)
   - Security foundation (JWT, OAuth2)
   - **Data Quality Scoring System** (prevents data quality death spiral)
   - **Economic Calculations Integration** (must-have feature for match acceptance)
   - **Hybrid Automation Model Definition** (automated vs. facilitated routing)
   - **50+ Participants Target** (critical mass threshold)

2. **Important for Scale**: 
   - Event-driven architecture with Go workers
   - Graph database optimization
   - Go 1.25 experimental features (JSON v2, GreenTea GC)
   - Monitoring (Prometheus, OpenTelemetry)
   - **IoT Integration Priority** (30%+ integration rate target by Phase 2)
   - **Facilitator Marketplace** (enables hybrid automation model)
   - **Data Quality Incentives** (progressive refinement requirements)

3. **Future Enhancements**: 
   - GraphQL (gqlgen)
   - Mobile app (PWA)
   - Advanced analytics
   - gRPC microservices
   - AI/ML integration (Phase 3+, appropriately timed)

### Key Go 1.25 Advantages

- **Performance**: 10-40% GC overhead reduction with GreenTea
- **JSON**: 3-10x faster with JSON v2
- **Container**: Automatic CPU resource management
- **Concurrency**: Goroutines for efficient parallel processing
- **Deployment**: Single binary, smaller containers

### Technical Spine

That's your **technical spine**. It's tractable, uses boring reliable tech (Neo4j + Go 1.25 + React), and scales linearly with data.

You can build a credible demo in a quarter and have something real to sell to municipalities or industrial parks before you ever touch pipes or pumps.

### Tactical Execution Priorities (From User Feedback Integration)

**MVP Focus Areas** (address cold start and adoption):
1. **Multi-Channel Data Acquisition**:
   - **Seed Data**: Import public registries, building footprints, utility maps, industry association data
   - **Forced Adoption**: Bundle with mandatory processes (CSRD, energy audits, municipal permits)
   - **Partner Ingestion**: Utilities/industrial parks provide anonymized facility data
   - **Incentive Rewards**: Priority matching for complete profiles, fee discounts for data contributors
2. **Privacy-First Design**: Public/network-only/private tiers with anonymized discovery
3. **Low-Capex Matches**: Focus on waste pickup, maintenance, shared services (no pipes required)
4. **Trust Building**: White-label municipal operation, industry association backing
5. **Facilitator Ecosystem**: Curate and train local engineering/ESG consultancies with platform templates

**Revenue Model Evolution**:
1. **Free Tier**: See + Match (drive network effects)
2. **Basic**: Shared OPEX deals (€50/facility/month)
3. **Business**: Full symbiosis + facilitators (€150/facility/month)
4. **Enterprise**: Integration + white-label (€500/facility/month)

**Channel Strategy**:
- **Utility Partnerships**: They provide data, you provide UI
- **Municipal Dashboards**: Charge cities, give companies free access
- **Facilitator Marketplace**: 10-20% commission on intermediated deals

**Success Metrics**:
- 20 companies, ≥5 actionable matches, ≥3 implemented connections
- ≥60% data completion rate, clear revenue path within 6 months

Each recommendation should be evaluated against project constraints (time, budget, team expertise) and documented as an ADR when implemented.
