Giorgio wrote and published Mutiny's shutdown announcement on 5 August 2024. He describes the origin of the product in the same post: the idea for a self-custodial Lightning wallet came out of a conversation at Pleb Lab with two others, became an experiment at a hackathon, was thrown away once, and returned as a Lightning node compiled into a website after the team's Apple developer account was flagged as sanctioned.
He was one of three first-time founders who incorporated the company, raised $300,000, and raised a further $500,000 at the end of 2023. In the same August 2024 post he stated he would step down as chief executive and take the chief technology officer role, with another team member moving up to run the company.
The engineering he led is documented in that post: a multi-device local-first synchronisation store that held the Lightning state of nearly 50,000 nodes over a year, one of the first Fedimint wallets, the first hybrid Fedimint and self-custodial Lightning wallet, and a signet instance used by other developers and companies.
