A startup IT team formalizing support. Small internal IT groups moving off email and chat that need an affordable, quick-to-deploy service desk without ITIL complexity.

A large regulated enterprise. Big organizations that need deep customization, security, compliance controls, and scale across thousands of employees and multiple departments.

A software company already using jira. Development-heavy teams that want ITSM tightly connected to their existing Atlassian tools and engineering workflows.

A managed service provider. MSPs supporting multiple client organizations who need multi-tenant ticketing, asset tracking, and billing-friendly reporting.

A mid-market it operations team. Growing IT departments that want ITIL-aligned incident, problem, and change management with a self-service portal at moderate cost.

A corporate shared services team. HR, facilities, and finance groups extending service desk workflows beyond IT for company-wide employee request handling.
