- Capital B (Euronext Growth Paris: ALCPB.PA), formerly The Blockchain Group SA, operates as Europe's first Bitcoin Treasury Company, focused on accumulating and holding Bitcoin as a long-term strategic reserve asset using excess cash flows and financing instruments while developing technology consulting and services in Data Intelligence, AI, and decentralized technologies; it provides custom digital applications, web development, business intelligence tools, AI-powered decision-making solutions, data analytics, blockchain infrastructure integration, and decentralized applications through its subsidiaries. The company, founded in 2008 and headquartered in Puteaux, France, employs 135 people and primarily serves public and institutional clients across France and international markets via two main operating entities—iOrga for custom applications with traditional and decentralized technologies, and Trimane for end-to-end Data Intelligence solutions—along with specialized subsidiaries in AI and blockchain consulting. Recent developments include a name change to Capital B in November 2024 to reflect its Bitcoin treasury strategy; multiple capital increases in 2025, such as a €58.1 million accelerated bookbuild in September, €5 million subscribed by Adam Back in July enabling 44 BTC purchases, and an ATM-type program with TOBAM yielding additional BTC acquisitions; and aggressive Bitcoin accumulation, with confirmed purchases like 551 BTC for €54.7 million on September 22, 5 BTC for €0.4 million on November 25, 58 BTC for €5.9 million in July, and others bringing total holdings to 2,823 BTC as of late 2025, achieving a BTC Yield exceeding 1,400% year-to-date.
