Three revenue streams: 1. Home Sales (Primary): We sell prefab Solo Homes at €150-180k per unit. Construction cost: €80-100k (prefab build + BYD battery system + installation). Gross margin: 40-50% per unit. We pre-sell homes, collecting €30-50k deposits to fund construction - minimizing capital requirements. 2. Energy Services (Recurring): Each home's BYD battery participates in grid balancing markets (Elering/Fingrid). We aggregate capacity across our homes and split revenue 60/40 with homeowners. Per home: €2,000-3,000/year gross, we retain €800-1,200/year. This creates recurring revenue that scales with each home delivered. 3. Battery Installation Markup: 15-20% margin on BYD battery system integration (€10-15k per unit = €1.5-3k profit per home). Unit Economics (per Solo Home): Sale price: €160k Build + battery cost: €90-100k Gross profit on sale: €60-70k Annual recurring energy revenue: €1k/year Lifetime value (10 years): €70-80k per home Go-to-market: Target expats and digital nomads in Tallinn/Helsinki through partnerships with relocation agencies, tech companies, and startup communities. Pre-sales model reduces capital needs - we build only after securing deposits. Scalability: Year 1: 3 homes (€480k revenue). Year 2: 10 homes (€1.6M revenue + €30k recurring). Year 3: 20 homes (€3.2M revenue + €150k recurring).

GrinaHomes: Energy-generating apartments for Baltic expats. Prefab one-bedroom units with BYD batteries that earn residents €2-3k/year from grid services. Raising €50k to launch pre-sales and deliver the first 3 units in 2026. Making homeownership pay for itself.
