Sonja Merz GmbH

What Sonja Merz GmbH does

Sonja Merz GmbH is a privately held German limited liability company (GmbH) founded in 1999 by gastronome Sonja Merz, headquartered in Stuttgart, Baden-Württemberg. The company operates a hospitality and events business anchored by its flagship Sonja Merz Festzelt, a 5,000+ seat festival tent at the Cannstatter Wasen during the Cannstatter Volksfest. The venue is segmented into multiple price and experience tiers — Mittelschiff, Stadel, Sonja Merz Loge (270 guests, with star chef Andreas Bäßler), Empore, SchatziBar, and PilsBar — and runs a rotating calendar of themed events including VfB Fan Club Treffen, Reiterparty, Darts & Gaudi, and exclusive corporate (Firmenwasen) events. A value-mark (Wertmarken) system is used to convert reservations into minimum-consumption food and beverage spend.

The company operates with a lean 5-employee core and extends its brand into year-round sub-brands: a Biergarten at Schlossgarten, a Weindorf, the Weihnachtsparadies (Christmas venue), and an Eventcatering service. Revenue is generated across five streams: on-site food and beverage sales, table reservations (via the reservia.online widget), special event packages (birthdays, bachelor/bachelorette, champagne specials), branded merchandise through the 'Was'n Style' e-commerce shop (shipping domestically for €17 and internationally for €19), and corporate event branding (logo placement on Lebkuchenherzen, admission bands, LCD screens). Marketing relies on Instagram and Facebook (@sonjamerzzelt), an email newsletter, the Wix-hosted website, and earned media through partnerships with BILD Zeitung and Sport1.

The core technology stack is minimal and conventional: a Wix website, a third-party reservation widget, and standard e-commerce. There are no disclosed AI/ML capabilities, no proprietary platform, no APIs, and no mobile app; the competitive position rests on the scarce Cannstatter Wasen venue slot, the founder's 25+ year personal brand, and curated partner relationships (Stuttgarter Hofbräu for beer, Veuve Clicquot for champagne, Weingut Diehl for wine). Founded in 1999, with the flagship tent launching in 2009 and the 'Was'n Style' merchandise line in 2018, the business is preparing for the Cannstatter Volksfest 2026 season (September 25 – October 11, 2026).
