About Briefcase

We are a London-based seed startup redefining how accounting is done. We’re creating a platform that automates the most tedious and time-consuming aspects of accounting, from bookkeeping to month-end close, using technologies like multimodal AI, agentic workflows and embeddings.

Currently on a rapid growth trajectory, we’ve partnered with several accounting firms in the UK, including a top 100 practice. We’re building fast and iterating based on frequent customer feedback and a validated product roadmap.

Backed by $3M in funding with over 24 months of runway, our investors include Earlybird, Tiny, Entrepreneur First, and world-class angels such as Charlie Songhurst, the founders of accounting tech unicorn Pennylane and scouts from Sequoia and a16z.
