The Yield-Generating Prefab: Housing Meets Fintech.

We integrate AI-driven energy arbitrage into high-performance modular homes, allowing homeowners in Estonia and Finland to trade energy on the Nord Pool spot market automatically.

How It Works

Smart Prefab Hardware

Sustainable, high-insulation Finnish wood modules with integrated solar skins.

The GrinaPay Arbitrage Engine

Our proprietary software monitors real-time electricity prices. It charges your home battery when prices are negative and sells back to the grid during peak spikes.

Monthly Yield

Homeowners receive a "Dividend" that offsets their mortgage, managed through our fintech dashboard.
