Business management software for heavy-duty truck dealerships and shops
Karmak builds Fusion, a dealer management system for heavy-duty trucking, on a classic Microsoft stack: C#, VB.NET, WinForms, SQL Server and Azure DevOps. The WinForms and VB.NET footprint alongside new mobile app and messaging projects points to a desktop-era product extending to mobile. Hiring is accelerating, engineering-led with a Software Development Director search, while support pain around call volume and escalations shows strain on the customer side.
