What Sundayapp does
Sundayapp (Sunday App, Inc PBC) is an Atlanta-headquartered fintech founded in April 2021 by Big Mamma restaurant-group founders Tigrane Seydoux and Victor Lugger. The company provides an AI-native QR-code and handheld payment platform purpose-built for full-service restaurants, deployed across 3,500–5,000 venues in the United States, France, and the United Kingdom, with a planned launch in the United Arab Emirates in January 2026. As of late 2025 the platform processes more than $4 billion in annual transaction volume and serves roughly 80 million diners per year.
The product architecture centers on three in-venue payment surfaces — Digital Bill (QR-code pay-at-table), Smart Handheld (a hospitality-specific card reader with WiFi/Ethernet plus 4G and offline backup), and the newly launched Hybrid — wrapped by the AI-driven Guest Platform that unifies ordering, payment, and loyalty across dine-in, takeaway, and online channels. Layered on top are AI-branded modules (AI Tips®, AI Reconciliation®, AI Menu®, AI Guest Platform) plus operations, team, guest-engagement, and analytics modules (Staff App, Loyalty, Online Reputation, Branding, Guest Insights, Business Analytics, Customer Analytics). Underlying integrations cover the major US POS systems (Toast, NCR, Clover, Micros, Square, SpotOn, Lightspeed, Upserve), loyalty providers (Pongo, Paytronix, Como, Thanx, ZeroSix), reservation platforms (SevenRooms, Resy), and payment processing via Checkout.com, with PCI DSS Level 1 certification.
Revenue is generated primarily through percentage-based transaction fees on guest bills, supplemented by hardware sales of Smart Handheld terminals, recurring SaaS subscriptions for the value-add modules (sold mainly to multi-unit groups), and an indirect referral channel that pays operators $1,000 per onboarded location. Go-to-market is sales-led and demo-driven, with US field sales in six metros, an SDR/AE outbound motion, dedicated enterprise Operations Managers in NYC and Atlanta, an inside-sales engine in Paris, and an operator-driven referral programme. The company has raised $121 million across a $100M Coatue-led Series A in 2021 and a $21M DST-Global-led Series B in November 2025, and has approximately 251–500 employees that tripled over 2024/25.

Revenue model
- Payment Transaction Fees: Primary revenue stream: service fees calculated as a percentage of the bill amount when guests pay via sunday (per User Terms of Service, Section 3). Consumers can opt to pay the Establishment directly with a credit card to avoid the service fee. Marketing material states sunday Pay-at-Table 'offers cheaper transaction costs based on your usage' and combined with Smart Handheld 'the cheapest transaction costs on the market'.
- Hardware Sales (Smart Handheld terminals): Revenue from sale or placement of sunday's hospitality-specific handheld card readers, distributed and configured during onboarding alongside QR-code kits.
- Value-Add SaaS Modules (Loyalty, Analytics, Branding, Reputation, Staff Performance): Premium product modules (Online Reputation, Loyalty, Business Analytics, Customer Analytics, Staff Performance, Custom Branding, AI Menu, AI Tips, AI Reconciliation) layered onto the core payment platform and sold primarily to multi-unit and enterprise groups.
- Referral / Lead-Generation Economics: Operator-driven acquisition channel monetised indirectly via $1,000 referral payouts (capex-style CAC) that fuel rapid restaurant onboarding and downstream transaction volume.

Sundayapp competitors and assessment
Company assessmentDirect peers
- SpotOn: Restaurant POS, payments and marketing software competitor serving US hospitality operators. Comparable to sunday in target customer (full-service and multi-unit restaurants), product breadth (POS + payments + loyalty) and SMB-to-enterprise go-to-market motion.
- Bbot: QR-code ordering and payment platform for restaurants. Directly comparable to sunday's Digital Bill and Order & Pay flows in QR-based dine-in payments and ordering, targeting similar full-service and casual dining venues.
- Olo: Public restaurant SaaS powering digital ordering, payment and loyalty for enterprise chains. Directly comparable to sunday in digital ordering/payment rails and enterprise hospitality customer base, but more focused on off-premise (delivery, pickup) ordering than in-venue pay-at-table.
- TouchBistro: Restaurant POS and payments platform with integrated ordering, payments and floor management. Comparable to sunday in targeting full-service restaurants with bundled payments and add-on modules like reservations and loyalty.
- Toast: Restaurant-focused POS and payments platform serving US full-service and QSR operators. Directly comparable to sunday as a vertically-integrated restaurant payments/ordering/loyalty suite and a primary integration partner, making it both the largest distribution channel and the most direct competitive threat.
- Lightspeed Commerce: Restaurant and retail POS/payments platform with pay-at-table, ordering and analytics modules. Comparable to sunday in targeting full-service restaurants and offering integrated ordering-to-payment workflows, including the Upserve variant sunday explicitly integrates with.
- Presto (formerly E la Carte): Specialist in pay-at-table handheld tablets and AI-driven restaurant ordering. One of the closest direct comparables to sunday's Smart Handheld pay-at-table product, focused on the same in-venue checkout and tipping workflows for US chains.
Broad incumbents
- Clover (Fiserv): Large-scale SMB POS and payments platform from Fiserv used by many US restaurants. Comparable to sunday as a payments and POS provider at the table, but competes as part of Fiserv's much broader commerce platform rather than as a hospitality-specialist.
- Square (Block): Payments and POS giant with substantial restaurant vertical through Square for Restaurants. Comparable to sunday as a payments-and-loyalty solution for restaurants, but operates at much broader scale across all SMB verticals rather than specializing in hospitality.
Emerging players
- Resy (American Express): Restaurant reservation and guest-engagement platform owned by American Express. Comparable to sunday's reservation integrations (SevenRooms/Resy) and adjacent in targeting hospitality guest data, but does not offer sunday's core in-venue payment rails.
