Briefcase is an AI-native accounting and bookkeeping automation platform for UK accounting firms and businesses. Founded in 2024 in London by Reuben Steenkamp and Ján Stehlík, and backed by Earlybird Venture Capital, Entrepreneur First and Tiny, Briefcase describes itself as building the world's first AI autopilot for accounting firms. The product uses multimodal AI and agentic workflows to automate the most tedious parts of accounting: extracting data from invoices, receipts and bank statements, categorising transactions against a firm's chart of accounts, handling VAT (with embedded HMRC legislation for standard, reverse-charge and zero-rated VAT), automating prepayments and expense claims, and driving month-end and financial close. It publishes results into Xero and QuickBooks. Briefcase is delivered as a cloud SaaS application (app.briefcase.so); it is a consumer of accounting APIs rather than a public API producer, and at the time of this profile it publishes no developer/API documentation, OpenAPI, or SDKs.
