BOS Raise $10M to Expand Institutional BTCFi With Top Global Investors

BOS Secures $10M to Advance Institutional BTCFi

BOS Secures $10M The raise comprises top angel investors including CEO of Anchorage Digital Nathan McCauley’s MMW 2020 Trust, ex-Blackrock Private Equity Partners Paul Taylor and, CEO of Spartan Group Leeor Groen.

London, United Kingdom - Tuesday, 21 October, 2025: Today, BOS (BitcoinOS), the unifying operating system transforming Bitcoin for digital economies, announces $10M in total raised at the close of their funding rounds.

Greenfield Capital led the strategic rounds, with backing from other capital investors including FalconX, DNA Fund, Bitcoin Frontier Fund, Trust Machines, UTXO Management, LR Ventures, Silvermine Capital, and MMW 2020 Trust. Angel investors like Paul Taylor (former Blackrock Private Equity Partners), and Leeor Groen (Spartan Group Partner) also participated in the rounds. 

Funding will be primarily used to continue the momentum of technological achievements to transform the internet into a unified international economy of trust built on Bitcoin. The  BOS roadmap ahead includes ramping up the production phase of both institutional and developer protocols before market-ready roll out.

Founding Partner of Greenfield Capital Jascha Samadi said, “BitcoinOS's successful verification of ZK proofs directly on Bitcoin mainnet represents a fundamental breakthrough in blockchain infrastructure. They've achieved true Bitcoin programmability without modifying the base protocol—solving a challenge the industry has faced since Bitcoin's inception. This technology transforms Bitcoin from a store of value into the secure foundation layer for the entire digital asset ecosystem.”

BOS CEO and Co-founder Edan Yago affirms, “We are now in a very exciting time for Bitcoin, and this fundraise will strongly contribute to its exponential growth. Our work is the innovative heart in realising the future of the world’s most valued digital asset as a global financial system. 

The confidence instilled in us from capital investors and Bitcoin-focused funds is testament to the high demand and strong market excitement in our achievements. We are proud to accelerate Bitcoin and BTCFi into true mainstream adoption while maintaining the decentralized and trustless ethos it was founded upon.”

Launched in July 2024 with an industry-changing milestone of verifying the first-ever ZK-Proof on the Bitcoin mainchain, BOS has been focused on upgrading Bitcoin to do everything that other blockchains can, without forking its code.

This has been further demonstrated in a series of significant technological innovations that unlocks $2.2 trillion worth of Bitcoin liquidity across ecosystems and institutions. 

Highlights include an industry-first bridgeless cross-chain asset transfer, and the launch of Charms, the first protocol for programmable tokens on Bitcoin. BOS has also integrated with multiple ecosystems, notably Cardano, Ethereum and Litecoin, to enable trustless Bitcoin bridging. 

Most recently, BOS introduced Grail Pro, an institutional-grade protocol that allows institutional BTC yield generation while retaining self-custody. This is currently in a pilot with key institutions and custodians as Grail Pro aims to unlock $690M of institutional BTC securely.

With Bitcoin continuing to reach all-time high prices and institutions increasingly adding BTC to their treasuries, BOS is now even more uniquely positioned to capitalize on this momentum as it further develops its pioneering protocols to expand Bitcoin’s infrastructure and utility for both retail and institutional participants.

About BitcoinOS

BOS (BitcoinOS) is the ultimate upgrade to Bitcoin. Its breakthroughs in the use of ZK proofs allow it to embed any computation directly into Bitcoin transactions. This allows for a shared infrastructure layer for the first true Bitcoin L2s that feature total L1 security, trustless bridging, scalability, natively private transactions, and fully programmable tokens on Bitcoin.

BOS’s modular infrastructure acts as an operating system that creates seamless interoperability among all L2s within the system. As such, BOS fully maintains Bitcoin’s network effects, and establishes a permissionless, peaceful paradigm for the original chain to evolve in layers without ever needing to fork its code.
