Tateru \Japan
Tateru was a Japanese proptech company that operated a digital platform for apartment investment and construction management. Founded in 2006, Tateru positioned itself as a tech-enabled real estate investment facilitator, connecting individual investors with apartment building opportunities through a streamlined online platform. The company went public and aimed to democratize real estate investment in Japan's aging society, where rental property ownership was seen as a retirement income strategy. Their value proposition centered on reducing friction in the apartment investment process—from land sourcing and construction management to tenant placement and property management. The 'why now' was Japan's demographic crisis: an aging population seeking passive income, combined with digital transformation of traditional real estate processes. Tateru promised data-driven site selection, transparent pricing, and end-to-end service through technology, targeting salaried workers who wanted to become landlords without traditional barriers.

Execution Plan
Phase 2
Step 2 - Validation (Months 4-6): Expand to full lease lifecycle management. Add features: AI-generated lease agreements (customized to Japanese law), digital signature integration, automated rent reminders, and basic maintenance request tracking. Convert screening customers to $99/month subscription (unlimited screenings + lease management for up to 10 properties). Target: 50 paying subscribers, $5K MRR. Conduct 20 in-depth user interviews to identify next highest-value feature. Key validation: Churn <5%, users managing average 6 properties each.
Phase 3
Step 3 - Growth (Months 7-12): Launch full property management OS with AI assistant ('Kanri-san'). Add: Predictive maintenance alerts, rent optimization recommendations, tenant communication portal, financial reporting/tax prep, and marketplace integrations (insurance, contractors, legal services—take 10-15% commission). Implement PLG motion: Free tier for 1 property, $149/month for up to 20 properties, $499/month for unlimited + API access. Target: 500 paying customers, $60K MRR, 30% month-over-month growth. Distribution: Content marketing (SEO for 'Japanese landlord' keywords), partnerships with real estate investor associations, and referral program (1 month free for each referral).
Phase 4
Step 4 - Moat (Months 13-24): Build data moat and enterprise tier. Aggregate anonymized data across portfolio to offer market insights: neighborhood rent trends, tenant quality indicators, optimal property improvements. Launch 'Kanri Enterprise' for property management companies managing 100+ units at $2K-10K/month with white-label options, API access, and dedicated support. Develop proprietary underwriting model using our dataset—license to banks/insurers for additional revenue. Target: 2,000 landlords + 20 enterprise customers, $300K MRR, Series A fundraise. The moat: Our AI has seen more Japanese rental transactions than any competitor, making our recommendations and risk assessments the industry standard. Landlords can't leave because our data-driven insights are irreplaceable, and we've become the system of record for their entire operation.
Monetization Strategy
Three-tier SaaS model with transaction revenue overlay. TIER 1 - 'Starter' ($99/month): For landlords with 1-10 properties. Includes unlimited tenant screenings, AI lease generation, basic maintenance tracking, and tenant communication portal. TIER 2 - 'Professional' ($299/month): For 11-50 properties. Adds rent optimization AI, predictive maintenance, financial reporting, tax document generation, and priority support. TIER 3 - 'Enterprise' (Custom pricing, $2K-10K/month): For property management companies with 50+ units. Includes white-label options, API access, multi-user accounts, dedicated account manager, and custom integrations. TRANSACTION REVENUE: 10-15% commission on marketplace services booked through platform (insurance, maintenance contractors, legal services, renovation projects). Average landlord spends $500-1000/year on these services, generating $50-150 additional revenue per customer annually. DATA LICENSING: Aggregate, anonymized market data sold to banks, insurance companies, and institutional investors for underwriting and market analysis—estimated $50K-200K annually once dataset reaches critical mass. UNIT ECONOMICS: CAC ~$300 (primarily content marketing and partnerships), LTV ~$4,800 (average 4-year retention at $100/month effective revenue including transaction fees), LTV:CAC ratio of 16:1. Gross margins ~85% (pure software with minimal support costs due to AI automation). Path to $10M ARR: 3,000 customers at $278 average monthly revenue (blended across tiers + transaction fees). Conservative given Japan's 6.5M landlord TAM and 15,000+ property management companies.
