The Challenge

Finance Tooling Was Not Built for the AI-Agent Era

The finance stack most founders inherit is fragmented, expensive, and locked away from the AI tools they actually use every day:

Bookkeeping, invoicing, payroll, tax, and reporting spread across four or five disconnected tools

Traditional accountants charging £100-300/month with limited availability and slow turnaround

No way for an AI agent (Claude, ChatGPT, custom agents) to read or act on financial data directly

Compliance complexity multiplying for founders operating across multiple markets and currencies

"These challenges required a comprehensive, strategic approach to deliver exceptional results."
