Rational develops artificial intelligence agents designed to support internal accounting teams. These AI coworkers integrate directly into a company’s systems, autonomously building a comprehensive understanding of the organization’s financial operations. They handle routine tasks such as month-end closing and tax preparation while maintaining accurate records and ensuring compliance.
The system also manages communication by identifying and reaching out to the appropriate team members when action is needed. This reduces manual follow-ups and streamlines workflows. Based in San Francisco, Rational was founded in 2026 and operates as a B2B AI startup with a small founding team. The company focuses on enhancing efficiency within enterprise accounting departments through intelligent automation.
