a41

a41 is a South Korean blockchain infrastructure provider and investment firm founded in July 2021 by CEO John Park. Initially established as a41 Ventures, the company focused on seed and early-stage investments in Proof of Stake (PoS) protocols, Play-to-Earn (P2E), and DeFi projects. A significant rebranding occurred in September 2022, shifting the primary focus to providing blockchain infrastructure services, backed by investors such as SK Inc, DSC Investment, and KB Investment.

The core of a41's business is operating as a multichain validator, providing enterprise-grade staking services for institutional and retail clients. This involves running secure nodes for over 20 Proof-of-Stake blockchains, including prominent networks like Ethereum, Sui, Aptos, and Cosmos Hub. By participating in network security and transaction validation, a41 helps maintain the integrity of these blockchains. The company's revenue is generated from commissions on the staking rewards earned by its delegators. With a reported $1.17 billion in staked assets under management and a 99.9% uptime, the firm positions itself as a major validator in the APAC region.

Beyond validation, a41 actively participates in the Web3 ecosystem through its venture arm, a41 Ventures, which continues to invest in disruptive technologies. The firm also dedicates resources to research, publishing in-depth articles on topics like modular blockchain structures, MEV (Maximal Extractable Value) centralization, and tokenomics to educate the community. The executive team includes CTO Juman Han, who guides the technical vision; CSO Tony Kim; and CBO Kevin Kim, who leads strategic growth and partnerships. This leadership team brings experience from major tech companies like Samsung Electronics and Riot Games.
