Capital B Raises $1.28M From Blockstream CEO Adam Back

Capital B's Latest Funding Round

Capital B announced Monday that Blockstream CEO Adam Back subscribed to a warrant issuance valued at 1.1 million euros, equivalent to $1.28 million. The warrant structure allows Back to acquire additional Capital B shares at a predetermined price over a set period, giving him further exposure to the Bitcoin treasury company without immediately diluting existing shareholders.

Back's Growing Stake

The warrant issuance deepens Back's investment in Capital B. As a cryptographer and longtime Bitcoin advocate who founded Blockstream in 2014, Back has maintained a public interest in Bitcoin-native financial infrastructure. Capital B's focus on Bitcoin treasury management and custody aligns with Back's long-standing advocacy for Bitcoin adoption by institutions.

Capital B is listed on French exchanges and operates as a Bitcoin treasury firm, positioning itself to capture demand from institutional and high-net-worth holders seeking regulated Bitcoin exposure in Europe. The company competes in a growing segment of Bitcoin financial vehicles, ranging from custody providers to Bitcoin-focused investment funds.
