What VSX VOGEL SOFTWARE does

VSX – VOGEL SOFTWARE GmbH (Dresden, Germany; founded 1993; ~25 employees) develops and sells Spaix, a CPQ (Configure, Price, Quote) software suite for the centrifugal pump industry. Spaix automates pump selection, performance curve adaptation, component configuration, and quotation generation based on hydraulic duty points and standards from the Hydraulic Institute, NFPA 20, and EU energy directives. The platform is delivered in three coordinated editions — Desktop (Microsoft Windows), Web (SaaS), and Mobile (iOS/Android) — all sharing a central Microsoft SQL Server database, with a Webservice API allowing manufacturers to embed Spaix functionality into their own web stores. The product line is now in its sixth generation (Spaix 6), extended by modules for fire-fighting pump sizing, motor sizing, VFD selection, pump replacement, spare-part lookup, and friction-loss calculation.

The company generates revenue primarily through subscription licensing (SaaS rental for Web/Mobile, annual subscriptions for Desktop) covering software, maintenance, hosting, and support, supplemented by professional services (data entry, custom programming, additional language translations) and premium add-on module subscriptions. Customers are predominantly enterprise pump manufacturers and major chemical-industry buyers (KSB, Sulzer, Xylem, Wilo, Pentair Jung Pumpen, HOMA, BASF, Bayer, Evonik, Merck), with distribution via direct enterprise field sales, self-serve SaaS onboarding, and developer/API integrations. Go-to-market is augmented by the impeller.net industry portal and the Global PumpSelector comparison service. The company has been part of the European Everfield Group since 2023, completed a generational leadership transition in 2024 (Christoph Becker appointed CEO, Matthias Siegel as COO), added a Head of Sales & Marketing in September 2025, and serves 100+ manufacturers across 50+ countries with software available in 30+ translations.

Direct peers

• VISCO Software: VISCO Software is a German provider of pump and valve selection software (e.g., VICPASS) that directly competes with VSX in CPQ for the pump industry. Most comparable in vertical focus, customer base, and product functionality.
• Tacton: Tacton is a Swedish CPQ vendor specializing in industrial manufacturers of complex configurable products, including pumps, elevators, and heavy equipment. Closely comparable in B2B SaaS CPQ for engineered industrial products.
• Configure One: Configure One provides CPQ software for industrial manufacturers with complex product configurations. Comparable to VSX in targeting B2B manufacturers that need rule-based configuration and quoting.
• KBMax: KBMax offers 3D CPQ software for complex manufactured products, addressing similar challenges of visual configuration, rules-based selection, and engineering-grade quoting that VSX solves for pumps.
• DriveWorks: DriveWorks provides design automation and CPQ tightly integrated with SolidWorks for industrial manufacturers. Comparable to VSX in automating engineered product selection and configuration for manufacturing customers.

Broad incumbents

• PROS: PROS is a broader CPQ and dynamic pricing platform serving multiple industries. Comparable at the capability level (CPQ/pricing optimization) but not specialized in the pump vertical like VSX.
• Salesforce CPQ (Revenue Cloud): Salesforce CPQ (formerly Steelbrick) is a horizontal CPQ solution within the Salesforce ecosystem. Overlaps with VSX's quoting functionality but lacks VSX's pump-domain engineering depth.
• SAP CPQ (CallidusCloud): SAP CPQ, derived from CallidusCloud, is a horizontal CPQ offering within the SAP ecosystem. Competes indirectly with VSX for enterprise quoting workflows but addresses multiple industries.
• Oracle CPQ (BigMachines): Oracle CPQ, originally BigMachines, is a horizontal CPQ platform integrated with Oracle CX. Comparable at the configure-price-quote capability layer but not specialized in pump selection.
• Conga (Apttus): Conga (which acquired Apttus) offers CPQ and revenue lifecycle management as a horizontal platform. Comparable in CPQ functionality for enterprise sales but lacks VSX's pump-engineering specialization.
