Trullion

Trullion, built by former Big Four and top-firm CPAs, is an AI accounting platform automating financial workflows for accounting and audit teams — data extraction, document matching, financial-statement validation, lease accounting, and substantive testing. Its AI assistant, Trulli, surfaces answers and patterns from a company's financial data in seconds, while the "Knowledge Layer" unifies internal guidelines, external accounting standards, and institutional knowledge in one place. The platform explicitly emphasizes "auditable AI" — explainable, traceable outputs rather than a black-box result — which matters directly for teams that need to defend their numbers to auditors or regulators. Customer names including HMD, Eisai, and Taboola, plus a live customer login portal, are concrete signs of real production use; pricing isn't published and requires direct contact. Good fit for an accounting or audit team that wants AI-assisted financial workflows with a clear, explainable audit trail rather than an opaque automated result they'd have to re-verify manually anyway.
