Grupo IOB serves Brazilian accountants and mid-market companies with tax and compliance solutions built on legacy infrastructure (Visual FoxPro, Delphi, SQL Server). The tech stack and stated pain points—tax efficiency, legal risk, legacy modernization—align with a company managing long-lived core systems while attempting incremental upgrades; minimal hiring velocity and sparse engineering headcount suggest constraints on pace of technical transformation.
