Last Accounting Company (LAC) is a full-stack AI accounting firm that replaces both traditional accounting firms and legacy accounting software with a single fixed-price service for startups and SMBs. AI agents handle all the work — bookkeeping, tax filings, VAT, payroll, and financial reporting — while a certified human accountant validates every output. The company has built a fully proprietary stack, from the general ledger to the accounting agents, enabling powerful self-reinforcing feedback loops. LAC has already processed over $80 million in transaction value for dozens of Finnish companies. The team was accepted into Y Combinator's Summer 2026 batch and is now targeting both European and US markets.
