Software that automates compliance for regulated, cross-border markets.

Attimus Group builds and operates software for regulated, cross-border markets, where compliance is complex, high-stakes, and poorly served by existing tools. The company designs products that turn manual, error-prone regulatory processes into reliable, auditable automation. Its current platform, Rentax, automates the monthly Brazilian federal tax-compliance process for non-resident property owners — integrating directly with Brazilian government systems, generating the required federal tax forms (DARFs), and maintaining a complete, auditable record of every filing.
