Jack Mallers is an American entrepreneur and the founder and CEO of Strike, a Lightning Network-based payments company. He is best known for his role in El Salvador's historic adoption of Bitcoin as legal tender and for his passionate advocacy for Bitcoin as a tool for financial liberation.
Early Career and Zap
Mallers began building Bitcoin software while still a teenager, growing up in Chicago in a family with a background in financial trading. His first major project was Zap, an early Lightning Network wallet and interface that he developed and released around 2018. Zap was one of the first user-friendly interfaces for the Lightning Network and helped make the nascent payment layer accessible to non-technical users. The project established Mallers as a serious contributor to the Lightning ecosystem despite his age.
Founding Strike
Building on his experience with Zap, Mallers founded Strike, which launched publicly in 2020. Strike's approach differed from typical Bitcoin wallets: it presented Lightning Network payments through a familiar consumer finance interface, allowing users to send and receive money in dollars (or local currency) while using the Lightning Network for settlement. This design made Strike immediately accessible to people with no prior Bitcoin experience.
Strike expanded internationally and became a primary gateway for Bitcoin-based remittances, particularly in corridors where traditional services imposed heavy fees. The company raised an $80 million Series B round in 2022 to expand its product offering and geographic reach.
El Salvador Announcement
At the Bitcoin 2021 conference in Miami in June 2021, Mallers delivered what became one of the most dramatic presentations in Bitcoin's history. He announced, with visible emotion, that El Salvador under President Nayib Bukele would become the first country to adopt Bitcoin as legal tender. Mallers had been involved in advising the Bukele administration and had worked with them on the technical implementation using Strike's infrastructure.
The announcement was simultaneously a landmark moment for Bitcoin adoption and a demonstration of the Lightning Network's potential as national payment infrastructure. El Salvador's Bitcoin law went into effect in September 2021, with Strike playing a significant role in the country's payment systems.
Lightning Network Advocacy
Mallers is one of the most vocal and charismatic advocates for the Lightning Network as a payment system. His presentations typically blend technical explanation with emotional arguments about financial access, remittance costs, and economic sovereignty. He has spoken at major conferences including Bitcoin 2024 and Adopting Bitcoin in El Salvador, and has consistently argued that Bitcoin, specifically over Lightning, represents the most viable path to a fairer global financial system.
Significance
Jack Mallers represents a new generation of Bitcoin entrepreneurs: technically capable, commercially aggressive, and deeply committed to Bitcoin's role in financial inclusion. His work on Strike and his involvement in El Salvador's Bitcoin adoption have made him one of the most consequential figures in Bitcoin's evolution from speculative asset to national currency. His ability to communicate Bitcoin's potential to mainstream and political audiences has given him an outsized influence relative to his age.
