Zeni

Zeni is an AI-powered bookkeeping and finance platform for startups and growing businesses, combining machine-learning automation with a dedicated human finance team.

Alongside AI bookkeeping, Zeni offers bill pay, employee reimbursements, business checking accounts and credit cards, payroll, tax accounting, and fractional CFO services. Zeni also ships a hosted, read-only MCP (Model Context Protocol) server that lets AI assistants such as Claude, OpenAI Codex, and Google Antigravity securely read a company's live Zeni financials via OAuth. The company reports managing more than $20B in transactions annually.
