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:

01

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

02

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

03

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

04

Compliance complexity multiplying for founders operating across multiple markets and currencies

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