Revenue model
- Tariff/Monthly Financing Payments: Bullfinch earns recurring monthly tariff revenue from end customers (homeowners and businesses) who finance solar, battery, heat pump, and EV charging systems. Two tariff tiers are offered: Ratenkauf (installment purchase) starting at €99.99/month and Mietkauf (rental purchase) starting at €109.99/month. Tariffs include maintenance and insurance coverage.
- Installer/Partner Commissions: Installers (channel partners) receive tiered commission payouts from Bullfinch upon contract signing (20%), installation completion (50%), and grid connection (30%). Bullfinch's revenue is generated from the spread between financing cost and tariff payments collected from end customers.
- Asset Management and Servicing: Bullfinch manages over 10,000 existing solar installations as a servicing agent on behalf of asset-owning entities (e.g., Deutsche Energie Infrastruktur I GmbH). Revenue is derived from service fees for maintenance coordination, rent collection, and customer support.
