About Capital B
Capital B is a French technology company listed on Euronext Growth Paris under ISIN FR0011053636 and ticker ALCPB. Formerly known as The Blockchain Group, the company rebranded as Capital B in July 2025, signaling a strategic shift in its corporate identity and market positioning. Today, Capital B describes itself as Europe’s first Bitcoin Treasury Company while continuing to operate technology businesses focused on data intelligence, artificial intelligence, and decentralized technology consulting and development. As a result, the group combines two dimensions: a service-and-engineering technology platform and a treasury strategy built around Bitcoin accumulation.
The company’s roots lie in blockchain and emerging digital technologies. Over time, it expanded its scope toward broader data intelligence and AI-related services to better address corporate digital transformation needs. This evolution reflects an effort to move beyond a narrow blockchain positioning and build a more diversified, innovation-driven offering. Capital B’s core activities are primarily anchored in Europe, but the group has also shown an international ambition. In 2025, it announced the ongoing creation of a subsidiary in Abu Dhabi, highlighting an intention to extend its footprint into the Middle East.

From an operational standpoint, the company’s business lines can be grouped into three main areas. First, data intelligence services, covering data structuring, exploitation, and monetization for business clients. Second, AI and related digital solutions, with consulting, integration, and development capabilities designed to help organizations deploy advanced technologies. Third, decentralized technology consulting and development, where the group leverages its historical expertise in blockchain, digital assets, and distributed architectures. In parallel, Capital B’s Bitcoin treasury policy has become a defining feature of its equity story and investor communications.
Capital B stands out in the market for its pioneering role in Bitcoin treasury management in Europe. The company regularly reports Bitcoin purchases, total holdings, and indicators such as BTC Yield, which has made it more than a conventional IT services provider. Its financial strategy relies on recurring funding rounds, including ATM-style capital increase programs with TOBAM and convertible debt issuances, to support its Bitcoin acquisition strategy. As of April 2026, the company reported holding 2,937 BTC, underscoring the scale of this treasury approach.
Overall, Capital B is an unusual French listed company positioned at the intersection of technology services, AI, blockchain, and Bitcoin treasury management. Its model combines operational tech activities with a high-conviction financial strategy, making it a distinctive name for investors interested in long-term digital transformation themes and European crypto-related exposure.
