Technische Computer Systeme

What Technische Computer Systeme does

Technische Computer Systeme Süssen GmbH (TCS) is a privately held German software and engineering services firm founded in 1980/1981 and headquartered in Süßen, Baden-Württemberg. The company specializes in IT-CAE (Computer-Aided Engineering) plant documentation for electrical engineering, serving the process and manufacturing industries across the DACH region and Switzerland. TCS operates a hybrid model combining professional engineering services with proprietary software products, targeting industrial clients that require standardized, DIN EN 61355-compliant electrical documentation, migration from legacy systems, and Industry 4.0 readiness.

The core software portfolio centers on Sigraph, a CAE platform for electrical and process engineering that TCS now develops and supports in-house following the July 2025 return of full development ownership. The underlying promis engine enables object-oriented data models that support Knowledge-Based Engineering (KBE), a methodology TCS has pursued since 2008 and is now extending with Large Language Models. Two complementary products, CDMRunner (automated PDF export from the CDM database) and TCSDocView (centralized PDF document management via intranet), extend the Sigraph ecosystem. Service lines include Elektrokonstruktion, technical documentation creation and maintenance, paper-to-digital digitization with OCR, migration consulting across multiple ECAE platforms (EPLAN, COMOS, Engineering Base, RUPLAN), custom software engineering, and Sigraph training delivered on-site, at the Süßen training center, or online.

Revenue is generated through one-time software licenses, project-based professional services contracts, and recurring training engagements. Customer acquisition is relationship-driven enterprise field sales with no broad marketing apparatus; the corporate website and direct contact (phone and email) serve as the primary commercial interface. The company is led by Managing Director Oliver P. Böttcher (M.Sc.) and maintains long-standing collaborations with Siemens and the University of Stuttgart from the original Sigraph development era. No parent company, external investors, or public listing are disclosed, and financial metrics including revenue and headcount are not publicly available.

Core offering

TCS develops, sells, and supports proprietary CAE software (Sigraph, CDMRunner, TCSDocView) and delivers professional engineering services for IT-CAE plant documentation, electrical construction, software engineering, digitization, and migration of legacy documentation to modern ECAE platforms. The company targets process and manufacturing industries with standardized, DIN EN 61355-compliant technical documentation solutions.

Product overview

Technische Computer Systeme (TCS) offers a unified product-service portfolio centered on IT-CAE plant documentation for Electrical Engineering, targeting the process and manufacturing industry. The core software products are Sigraph (the primary CAE platform for electrical and process engineering), CDMRunner (an add-on that automates PDF export from Sigraph by monitoring the CDM database), and TCSDocView (a document viewer for centralized PDF management). These three software products are complemented by professional services including Elektrokonstruktion (electrical construction), Dokumentation (technical documentation services), Digitalisierung/Scan-Service (digitization with OCR), Software-Engineering (custom development and AI solutions), Überführen und Migrieren (migration consulting), and Sigraph training. The company also develops Sigraph further as its own software product following its return to TCS in July 2025.

• Dassault Systèmes: Dassault Systèmes provides 3DEXPERIENCE platform and CATIA Electrical / SOLIDWORKS Electrical for product and plant electrical design. It competes for industrial engineering documentation budgets at large manufacturers as a broad incumbent.
• AVEVA: AVEVA provides industrial software (including electrical and plant engineering modules) for process industries. It is a broad incumbent competing for the same process-manufacturer documentation and digital-twin budgets that TCS serves.

Direct peers

• Zuken: Zuken's E3.series is an electrical CAD platform for wire harness, control cabinet, and process-industry design. It competes directly with Sigraph for industrial electrical engineering documentation, particularly in process and discrete manufacturing.
• WSCAD: WSCAD is a Germany-based ECAD software vendor focused on electrical engineering, cabinet layout, and building automation. It directly competes with Sigraph in the same DACH Mittelstand customer segment for electrical documentation and design.
• Aucotec: Aucotec develops the Engineering Base ECAD/CAE platform for plant and machinery engineering. TCS explicitly supports migrations to and from Engineering Base, making Aucotec a direct competing platform vendor in the same ECAE category.
• EPLAN: EPLAN is a leading ECAD/CAE platform for electrical engineering, automation, and mechatronics. It is the dominant incumbent in the German Mittelstand ECAD market and the primary competitive alternative to Sigraph for electrical construction and documentation.

Regional players

• Contact Software: Contact Software is a German PLM/PDM and engineering software vendor serving industrial customers in DACH. It addresses overlapping problems of engineering data management and documentation integration that TCS services also tackle for plant engineering clients.
