# FounderRunway Intelligence & Geo-Arbitrage Documentation
> Quantitative financial models, cost-of-living indices, and legal frameworks for bootstrapped founders extending startup cash runway via strategic international relocation.

## Core Capabilities & Calculations
- Interactive Startup Runway Calculator: Evaluates total capital reserves against Tier-1 baseline burn versus geo-arbitrage tech hub burn rates.
- Runway Extension Factor (REF): Calculated as (Monthly Burn Baseline) / (Monthly Burn Relocated). Typical extension ranges between 2.2x and 4.8x.
- Capital Preservation Rate: Net monthly liquid savings diverted directly into product engineering, user acquisition, and default-alive runway.
- Visa & Tax Regulatory Database: Real-time compliance data for Thailand DTV, Portugal D8/IFICI, Indonesia E33G Remote Worker KITAS, Colombia V-Nomad, Japan Digital Nomad, and Bulgaria 10% Flat Tax.
