Capital B has raised €7. 6 million from Bitcoin cryptographer Adam Back to accelerate its Bitcoin treasury strategy, tying fresh capital directly to further BTC accumulation rather than operating expansion.
Capital B has raised €7.6 million from Bitcoin cryptographer Adam Back to accelerate its Bitcoin treasury strategy, tying fresh capital directly to further BTC accumulation rather than operating expansion.
The French company disclosed the raise on September 2, 2026, describing Back as a strategic investor and framing the proceeds as fuel for its Bitcoin treasury company model, according to the company’s announcement. The financing is structured around the single purpose of expanding Bitcoin holdings on the balance sheet. For related coverage, see Bitcoin ETFs Rebound as Ethereum, XRP ETF Streaks End.
Adam Back, a longtime Bitcoin figure whose work on proof-of-work predates the network itself, is named as the source of the capital rather than treated as an incidental backer. His participation places a recognizable Bitcoin-native investor behind a corporate treasury vehicle, which sharpens the signal the raise sends to the market.

How the Capital Feeds a Bitcoin-Only Treasury
The use of proceeds is narrow. Capital B has positioned the raise as treasury expansion, meaning the euros are earmarked to be converted into BTC and held, consistent with the company’s stated identity as a Bitcoin treasury company in the same announcement.
That approach mirrors a wider pattern of firms concentrating balance-sheet reserves in a single asset, similar to Remixpoint’s shift to a Bitcoin-only treasury and to smaller accumulators such as Smarter Web’s steady BTC additions. For Capital B, the relevance is direct: new capital is designed to increase the number of coins under corporate custody.
The move follows an earlier, larger financing by the same company. Capital B previously pursued a capital raise that carried warrant-related dilution considerations, underscoring that the treasury build is being funded through repeated market issuance rather than operating cash flow.
Why Back’s Involvement Is the Story
Reporting tied to the Back investment quantified its intended effect on the balance sheet. Capital B aims to add 376 BTC to its treasury following the Adam Back commitment, CoinDesk reported on August 29, 2026, ahead of the formal announcement.
The pairing of a named Bitcoin cryptographer with a defined coin-acquisition target is what separates this from a routine equity raise. It converts an abstract financing into a concrete accumulation plan measured in bitcoin rather than in currency alone.
Capital B executive Alexandre Laizet publicly amplified the transaction on X, reinforcing the company’s messaging around the raise in a post tied to the announcement. His commentary aligns with the company’s positioning of the financing as a treasury-expansion event.
The near-term test is execution: whether the announced 376-coin target is fully acquired and reflected in the company’s reported holdings. Until Capital B confirms settled purchases, the raise remains a stated intention to add Bitcoin rather than a completed on-balance-sheet increase.
