Sumo Restaurants

What Sumo Restaurants does

Sumo Restaurants (legal entity: Sumo AS) is a Norwegian Asian fusion restaurant chain founded in 2010 and headquartered in Bergen, operating 15 restaurant locations across Norway's largest urban markets — Oslo, Bergen, Stavanger, Sandnes, Trondheim, Tromsø, and Jessheim. The company runs a unified hospitality platform built around four primary revenue streams: dine-in restaurant service, takeaway and home delivery (via its own sumo.katria.no ordering platform and a dedicated mobile app), corporate and private event catering (serving groups from 10 to over 2,500 guests), and private event hosting in specialized dining rooms including tatami rooms, chambre séparée, and a speakeasy in Oslo. The menu is built on a double-kitchen model that combines sushi/raw preparation with cooked Asian hot dishes, covering maki, nigiri, sashimi, poke bowls, dumplings, fried rice, noodles, and desserts across more than 100 SKUs, with active seasonal refreshes (Summer Menu 2026) and tiered catering packages priced from 299 NOK per person.

The business model is predominantly direct-to-consumer with a dedicated B2B overlay: a corporate sales team (led by sales contact Simerjit Singh Dhammi) handles custom enterprise agreements with invoice billing, overtime food delivery, and employee bonus programs. Monetization layers include digital and physical gift cards (12-month validity) and a CashPoints loyalty program earning 10% on online orders. Distribution is omnichannel — physical restaurants, own e-commerce platform, branded mobile app with push notifications, QR-table ordering, and social media presence on Instagram, Facebook, and TikTok. Payment processing is integrated through Netaxept (online), Westpay EMV terminals, Vipps, BankAxept, and major card networks.

Sourcing and sustainability form a meaningful brand pillar: Sumo's seafood supply comes from Lerøy (announced partnership 2019), which holds MSC and ASC certifications and supplies microalgae-fed salmon with antibiotic-free, non-GMO feed. The company operates under Norwegian GDPR-equivalent ('Lov om behandling av personopplysninger') data protection compliance. Sumo is privately held (no parent company, no disclosed institutional investors, no funding rounds recorded), appears to be family-influenced based on internal 'Sumo family' language, and reports 69 employees — a lean workforce relative to its 15-location footprint.

Emerging players

• Nudl Bar: Nordic poke and Asian bowl concept with a strong digital/loyalty focus. Comparable on the poke bowl segment of Sumo's menu and on the younger, mobile-first customer cohort.
• Poké House: European poke-bowl specialist with dine-in and delivery. Comparable on the poke-bowl line within Sumo's menu and on the health-leaning, digitally engaged customer segment.

Direct peers

• Sushi Shop: European sushi delivery and retail brand with strong digital ordering infrastructure. Comparable on sushi-centric menu, online ordering flywheel, and loyalty-driven retention mechanics.
• Yo! Sushi: UK-headquartered sushi and Asian bowl chain offering dine-in, takeaway, and delivery. Directly comparable on sushi-led menu, multi-format revenue (incl. retail and grocery ranges), and loyalty-driven repeat-visit model.
