R3 is a 51–200-person managed services firm built on Microsoft and cloud infrastructure (Azure, Intune, Defender suite, Logic Apps). The hiring mix—finance-heavy with senior and lead roles—paired with active projects around financial workflow modernization and automation, suggests the company is scaling back-office operations and internal delivery infrastructure rather than expanding service lines. Pain points around patch management, image deployment, and environment consistency point to operational friction in their own infrastructure delivery.
