CardNexus Raises $3.8M for TCG Marketplace App

Jan de Vries · 2026-06-11

CardNexus, a mobile-first marketplace and collection platform for trading card game (TCG) enthusiasts, just announced a $3.8 million pre-Seed round. The Bordeaux-based startup plans to use the funds to expand its team and game catalog. The round was led by Piton Capital, with participation from Motier, FSJ, OPRTRS, Kima Ventures, Aquiti, and a group of TCG content creators. ### The Problem CardNexus Solves Tristan Foureur, co-founder and CEO of CardNexus, explains why they built the platform: "We started CardNexus because we couldn't find a decent way to manage our own collections across the new games we started playing like Sorcery: Contested Realm. We decided to build from scratch for what collectors need today: one app for every game, with instant card scanning, card collection management, and a marketplace that works natively on your phone." The trading card game market is booming. Riftbound, the League of Legends card game, became a top-three seller within weeks of launch. Dozens of new games enter the market each year, bringing millions of new collectors with them. Yet the platforms serving this community, like TCGPlayer (now owned by eBay), were built over 15 years ago for a single game and haven't evolved since. ### What Makes CardNexus Different Founded in 2025, CardNexus is designed to be a companion for a collector's entire hobby, not just a place to buy and sell. The platform combines: - A peer-to-peer marketplace - AI-powered card scanning - Collection management across 12+ games - All in a single mobile app CardNexus says their community-led approach sets them apart. They have a public roadmap shaped by user feedback and an open API that lets developers and local game shops build on top of the platform. This transparency extends to pricing data, platform decisions, and product direction. In a market dominated by closed ecosystems, CardNexus is betting that openness wins. ### Early Traction and Growth The company launched their marketplace in March 2026 and now has over 50,000 users. It supports more than 12 trading card games, with plans to reach 20 by the end of the year. Over 30 million cards have been inventoried by users, including 10 million scanned via the mobile app, with active sellers spanning 30+ countries. This announcement comes in a context where comparable trading-card marketplace announcements are limited, but funding activity is visible across other specialized marketplaces. For example, Minimist, a Vienna-based technology startup building an AI-powered listing engine for second-hand retailers, closed a $1.1 million pre-Seed round in March. Webel, a Madrid-based digital marketplace for home services, closed a $4.7 million pre-Series A round. ### Future Plans This pre-Seed funding will be used to expand the game catalog, grow the team, and develop the platform beyond buying and selling. Over the next two years, CardNexus plans to become the companion app for every stage of a collector's journey. The company also plans to build a vault system for secure physical card storage, targeted for 2027. This would give collectors a way to store, insure, and trade high-value cards without shipping them back and forth. ### The Bottom Line CardNexus is betting that a mobile-first, community-driven approach can disrupt a market dominated by legacy platforms. With $3.8 million in fresh funding and early traction showing strong user engagement, they're positioning themselves to capture a growing niche in the TCG ecosystem.
