Revenue model
- Custom Engineering Services (Hardware, Firmware, Software): who generates revenue by providing end-to-end custom product development services — from consulting and feasibility analysis through hardware design, firmware/software development, EMC pre-testing, prototyping, documentation, certification, and series production support. Revenue is project-based and likely follows a milestone billing model aligned with the five-phase process described (Initial Consultation → Concept & Quote → Development & Integration → Verification & Conformity → Series Production & Lifecycle). Services are rendered for B2B customers in building automation, industrial automation, and medical technology.
- Off-the-Shelf Products (CAP-(I)-62386, BV2021-8, FetLON-Stack): who sells proprietary products including the CAP-(I)-62386 DALI protocol analyzer, the BV2021-8 LonWorks coupling transformer, and the FetLON-Stack LON protocol software library. These products are downloadable (software) or manufactured hardware components. Revenue is one-time or license-based for the software SDK. Products are also used within customer engineering projects.
- EMC Chamber Booking (External): who offers its in-house EMC chamber for external booking independent of development projects, for type tests and product qualifications. This represents a separate revenue stream from companies needing EMC testing capacity without a full development engagement.
