Jack is the core AI agent built by London-based startup Jenesys AI (founded November 2022), designed to act as an autonomous bookkeeper and auditor for B2B companies and UK accounting practices. It is powered by Jenesys's proprietary in-house Accounting Language Model (ALM) called Ark, which is not built on public AI models, ensuring client financial data remains in a closed, UK-data-centre ecosystem compliant with ISO/IEC 27001. Jack automates the full transactional accounting workflow: it captures invoices, extracts line-item data, assigns GL codes and VAT/tax codes, performs bank reconciliation, updates budgets, and checks compliance with laws and regulations, all in under 30 seconds per transaction. It operates via integrations into Slack and Microsoft Teams, as well as through Xero and other accounting platforms, enabling accounting teams to interact with it in their existing workflow tools. A key differentiator is Jack's fraud detection and compliance layer. It proactively flags changes to banking details (payee names, account numbers) and checks every transaction against identity, authority, budget, policy, and regulatory requirements in real time before any payment is made. Jack also provides an explainable 'reasoning' output for each decision, allowing accountants to challenge, audit, and bulk-correct GL code assignments directly. Jenesys also offers JackPod, a managed service that combines Jack's automation with a UK-based team of human bookkeepers who handle exceptions and validate outputs, targeting month-end delivery within seven working days. This hybrid model positions Jenesys against both pure-software tools and offshore bookkeeping services. The company raised $1.1 million in pre-seed funding (announced late 2023) from Twin Path Ventures, Fuel Ventures, Antler, and Hatcher+, with total funding reaching approximately $2.6 million. It is listed on the Xero App Store for UK accounting practices.
