Aaron Voisine, Co-Founder of BRD (formerly Breadwallet), Joins Brainwallet as Investor and Advisor

Crypto pioneer and serial entrepreneur joins the effort to grow Brainwallet 

London, UK – [Jun 5, 2026] – Grunt Software today welcomes Aaron Voisine, co-founder of BRD and an active angel investor to its advisory board. Voisine created the open-source SPV wallet code used by millions across BRD, Litewallet and Brainwallet. Bringing in a builder of his experience to guide the team is central to Brainwallet's next stage of growth.,

Decentralized cryptocurrency networks face an engineering challenge that closed financial clouds do not: protecting a user's identity while continuously syncing their wallet to the latest chain height and balance. Over the past eight years, the Grunt Software team has refined that core wallet functionality across Litewallet and now Brainwallet, making the experience faster, safer and easier to use. When Grunt Software managed Litewallet it surpassed 500,000+ downloads and served roughly 40,000 monthly active users. Brainwallet carries those same synchronization and security gains forward across 23 languages and 150+ countries.

"Kerry and this team have been quietly solving the hardest parts of wallet design since the early days when we were trading code on GitHub. They've taken everything they learned building Litewallet and turned it into one of the most approachable self-custody wallets I've come across. Getting everyday people comfortable holding their own crypto is work I care about, and I'm glad to be helping," said Voisine.

Cryptocurrency has reached the point where most people accept Bitcoin as a legitimate store of value. Grunt Software's goal is to normalize everyday spending, starting with Litecoin, where transactions are fast and inexpensive. Launched in 2011, Litecoin is one of the longest-running blockchains in operation, valued for its reliability and low fees. 

Building on that foundation, Grunt Software has set a near-term goal of growing Brainwallet to 2 million monthly active users.
