What CheckCheck does
CheckCheck is a digital authentication service that verifies sneakers, luxury handbags, apparel, watches, streetwear, and collectibles through photo-based submissions reviewed by two independent expert authenticators, supplemented by AI-assisted pattern pre-screening. Founded in 2019 and structured as CheckCheck LLC (New Jersey), the company operates from Hong Kong and serves individual consumers via a self-serve mobile app (iOS and Android) and web platform, with 3.3M+ app downloads and 2.5M+ items checked across 365+ brands globally. Each authenticated item receives a Digital Certificate of Authenticity with a non-reproducible QR code and server-side validation, accepted by major banks, PayPal, Whatnot, and TikTok.
The technology stack combines dual-expert human authentication (with senior escalation on disagreement) and AI-assisted image pattern detection, exposed through REST API, SDK, Webhooks, and a native Shopify integration for enterprise clients. CheckCheck for Business extends the core platform with barcode scanning, batch intake, a business dashboard, and a financial guarantee, while an official TikTok Shop Authentication Partnership embeds verification directly into live commerce.
CheckCheck generates revenue through a usage-based credit system (with bundle discounts, 20% Premium subscription off-tier pricing, and bulk discounts reaching under $1 per check at high volumes) supplemented by negotiated enterprise contracts. The customer base spans 10,000+ resellers worldwide, individual buyers, marketplaces (including Culture Circle in India), and Shopify merchants, with a small operating team of 11-50 employees supporting 24/7 global coverage and SLAs as fast as 5 minutes.

Revenue model
- Credit-Based Authentication (Usage-Based): Users purchase digital credits to pay for authentication checks. Each check consumes a certain number of credits based on item category and service level (e.g., 15-minute urgent check vs. 4-hour standard check). Credits can be purchased in bundles (6, 15, 30, 100 credits) with per-credit cost decreasing as bundle size increases. Credits expire within 24 months of purchase. A Premium subscription plan offers additional benefits including bonus checks and discounted per-check pricing.
- Enterprise / Business Plans: Volume-based pricing for high-volume sellers, marketplaces, consignment shops, and resale platforms. Enterprise plans include custom pricing, higher throughput, priority handling, dedicated dashboards, API integration, account management, and access to the fastest SLAs. Enterprise pricing typically ranges and is negotiated per client.

CheckCheck competitors and assessment
Company assessmentDirect peers
- Real Authentication: Real Authentication is a third-party authentication service for luxury handbags, sneakers, and accessories sold via the same photo-based submission model. It is the closest direct competitor to CheckCheck's core consumer authentication service.
- Authenticate First: Authenticate First is a third-party luxury authentication service for handbags, sneakers, and apparel sold by individual resellers. It mirrors CheckCheck's self-serve submission model and target customer of solo resellers and small businesses.
- Legit App: Legit App is a sneaker authentication platform that combines expert reviewers with AI to authenticate shoes for individual buyers and resellers. It directly overlaps with CheckCheck's sneaker category, self-serve mobile flow, and per-check credit pricing.
- Entrupy: Entrupy provides AI- and microscopy-based authentication for luxury handbags, sneakers, and apparel to enterprises and resale platforms. It targets the same B2B authentication-as-a-service customer base that CheckCheck serves via its API and Shopify integration.
Emerging players
- Sneaker Con AUTHENTICATOR: Sneaker Con, well-known for live sneaker authentication events, offers authentication services tied to its brand and event presence. It overlaps with CheckCheck's sneaker focus and consumer-trust positioning but is a more event-driven, emerging player in ongoing authentication.
Broad incumbents
- The RealReal: The RealReal is a major luxury consignment marketplace operating its own in-house authentication centers. While primarily a retailer rather than an authentication vendor, it shapes buyer expectations around authenticated luxury resale and competes for the same resale-authentication labor pool.
- eBay Authenticity Guarantee: eBay operates an in-house Authenticity Guarantee program for sneakers, watches, handbags, and trading cards on its marketplace. It is a platform-owned authentication competitor whose scale and free inclusion in listings pressure third-party authentication providers.
- GOAT: GOAT is a leading sneaker and apparel marketplace whose model relies on in-house authentication of every order before shipment. It competes directly with CheckCheck in sneaker authentication and serves a similar high-volume reseller and buyer base.
- StockX: StockX operates a global sneaker and streetwear resale marketplace with proprietary in-house authentication for every transaction. It is the dominant player in the same authentication-for-resale category CheckCheck targets via its API and consumer app.
- Vestiaire Collective: Vestiaire Collective is a global luxury resale marketplace with direct authentication teams. It competes with CheckCheck for marketplace-level authentication mandates and serves the same luxury handbag and apparel buyer/seller segments.
