Revenue model

1. Success-Based Transaction Fee (Buyers): Buyers pay a success-based mediation fee of 2% of the transaction volume (minimum €10,000) only when a company acquisition is successfully mediated through the platform. This is the primary revenue stream and aligns incentives between the platform and transaction completion.
2. Buyer Subscription Packages: Optional paid subscription tiers for buyers seeking to purchase businesses. Bronze (€50/month), Silver (€67/month), and Gold (€83/month) packages offer increasing numbers of online purchase requests (1, 3, and 5 respectively) with 12-month terms and automatic renewal. These are optional add-ons and do not replace the success fee.
