Bonial International Group

Bonial International Group is a single-family office anchored by a digital advertising platform that helps retailers and brands replace printed circulars with targeted digital promotions. The firm's core assets are kaufDA and MeinProspekt, two apps that offer location-based marketing and transparent pay-per-performance pricing. Founded in 2008, the company has built a network of over 1,500 retailers and brands, making it a market leader in German-language digital retail advertising. The strategy centers on three value propositions: replacing print circulars entirely, delivering geotargeted ads, and charging only for measurable results. Bonial's platform generates an average reading time of 90 seconds per digital circular, with Woolworth reporting a 70% cost reduction after switching from print (Altss estimate). Clients including Nespresso, dm, Schwartau, and Bering have used the platform to drive in-store traffic and new customer acquisition. Bonial's geographic footprint covers Germany and France, with additional corporate presence in Chicago. Bonial International Group's scale is underscored by 14.4 million monthly unique users and 16 years of operational history. The firm employs a lean corporate structure, with the family office managing both the advertising business and any related holdings. No recent operational events from the last 24 months were disclosed. The firm operates without a disclosed investment team or external capital — consistent with a single-family structure. Bonial's structural differentiator is its focus on a single, high-moat digital asset in a consolidating market. Rather than operating as a diversified family office, it owns and operates kaufDA and MeinProspekt, which serve as a direct bridge between local retailers and consumers. This tight ownership structure allows the firm to reinvest operating cash flow into platform expansion rather than external capital calls.
