Briefcase is an AI accountant/bookkeeper: aiming to replace the work, not just augmenting it. Accounting is a $700B+ industry still run on manual processes and human judgement. We’re building the leading AI-native platform to replace it; a fleet of 35+ AI agents running in production today, automating what used to require entire teams. We are not building a tool, we are replacing knowledge workers. Backed by Earlybird, Entrepreneur First, Tiny, and prominent angels such as Charlie Songhurst.
