Casim

What Casim does

Casim, formally "casim Gesellschaft für rechnerunterstützte Produktentwicklung und Prozessmanagement mbH & Co. Dienstleistungs-KG," is a privately held German engineering services firm founded in 1995 and headquartered in Kassel, North Hesse. The company delivers computer-aided engineering services — including construction/design, finite element analysis using ABAQUS, statistical tolerance management, geometric product specification, preventive quality (FMEA, 3D metrology, process capability), and energy efficiency consulting — to industrial manufacturers across automotive, medical technology, and industrial machinery. Named customers include B. Braun Melsungen, Herbert Kannegiesser, Sofotec, Audi, ZF/TRW, Fresenius, ebmpapst, and Black & Decker, several of whom describe Casim as a long-standing engineering partner.

Casim monetizes through three revenue streams: (1) fee-based engineering services delivered via direct enterprise engagement; (2) licensing and support for a proprietary software product family built around simTOL, a statistical tolerance calculation tool that performs worst-case, RSS, general statistical, and Monte Carlo-based tolerance chain analyses using convolution methods capable of handling non-normal distributions, with supporting products simQS (quality management documentation), simSERVICE (service management), and MSA Verfahren 1 (measurement system analysis); and (3) paid training seminars on tolerance management, statistical tolerancing, process capability, and simTOL usage.

The company is led by managing directors Dr. Frank Mannewitz and Dr. Dietmar Freitag. It holds TISAX certification (automotive information security) and ISO 9001:2015 certification (valid through 2028). Go-to-market is sales-led and primarily regional (Germany and broader Europe), supported by content marketing through a technical lexicon/blog, an email newsletter, in-person seminars, and an emerging webinar channel. Casim operates with no external disclosed funding, no parent company, and no subsidiaries.

Core offering

Casim provides engineering services for industrial product development, spanning construction (Konstruktion), FE-analysis, tolerance management, geometric product specification, preventive quality, energy efficiency consulting, and custom software development. The company also licenses its proprietary software products—simTOL (statistical tolerance calculation), simQS (quality management documentation), simSERVICE (service management), and MSA Verfahren 1 (measurement system analysis)—and delivers paid training seminars on tolerance management, process capability, and simTOL usage.

Product overview

Casim offers a suite of proprietary engineering software products centered on statistical tolerance management and quality assurance. The core product is simTOL, a statistical tolerance calculation software that performs worst-case, statistical, and Monte Carlo-based tolerance analyses on mechanical assemblies. simTOL is the platform on which the broader software portfolio is built. The product family is complemented by simQS (quality management documentation), simSERVICE (service management), and MSA Verfahren 1 (measurement system analysis capability assessment). These products are available with associated support services and are offered alongside Casim's engineering consulting services (construction, FE analysis, tolerance management, geometric product specification, preventive quality, energy efficiency, and software development).
