What Mainau Gmbh does

Mainau GmbH is a privately-held tourism operator that runs Insel Mainau, a 45-hectare flower island attraction in Lake Constance, Germany, drawing approximately 1 million visitors annually. Founded in 1974 when the Bernadotte family transferred the island into a corporate entity, the company operates year-round park and garden facilities across 25 hectares of show gardens featuring seasonal displays (tulips, roses, dahlias), a baroque castle and church, restaurants and catering venues, event spaces for corporate and private functions, and a 420-hectare FSC-certified mainland forest. The company is wholly owned by the Lennart Bernadotte Foundation, a non-profit foundation, and managed by the fourth generation of the Bernadotte family.

The company monetizes through a diversified revenue model spanning park admission (day tickets, annual passes, evening admission tier at €16 after 17:00 in summer), on-site catering across multiple restaurant concepts (Schlosscafé, Schwedenschenke, Comturey, pop-up dining), retail sales of Mainau-branded products (bio-wines, honey, gin, roses, garden merchandise) via a Shopify-powered e-commerce platform, conference and event venue rentals, and professional garden advisory services through its subsidiary Mainau Gartenprofis. Distribution combines direct-to-consumer online sales through webshop.mainau.de, on-site box offices, and a B2B sales partner network spanning regional travel companies, hoteliers, and tourist information offices. Technology infrastructure includes GPS-based digital visitor information, an AI customer service assistant 'Mika' (built on Moin.ai by knowhere GmbH), AI-assisted phone handling, and integrations with PayPal, Klarna, Sendinblue, and Shopify. The company maintains certifications including EMAS, Bioland (30 years), FSC, and ISO 16001, and operates without public subsidies on market principles.
