What dia solutions does

dia solutions GmbH is a privately held Swiss software and engineering services firm headquartered in Basel, founded in 2017 by engineers from Siemens automation and CSL Behring. The company operates two interlocking lines of business: Siemens COMOS consulting and custom software development, and its own SaaS product, Rundfix. Through its status as an official Siemens COMOS project partner since 2019, dia solutions delivers custom development, integration, and optimization across all COMOS modules (PID, EI&C, Web, REST, MRO, PQM) to engineering teams at industrial clients.

Rundfix, launched in 2023, is a web- and mobile-based SaaS platform for digital operations documentation in plant management, offering digital round planning, mobile data capture, digital diaries, and shift management. It is distributed globally via the Apple App Store and Google Play Store, with data hosted in ISO 27001-certified data centers in Switzerland or Germany, and uses a modern stack spanning React/Next.js/TypeScript on the frontend, Node.js/.NET/Python/Go on the backend, React Native/Flutter on mobile, and PostgreSQL/MongoDB/SQL Server databases, deployed across AWS, Azure, and Google Cloud. The company also builds custom progressive web apps and native iOS/Android applications, including an Asset Management Platform delivered in 2021 with an interface to Energy Data Management Systems (EDMS).

Revenue is generated through quote-based annual subscriptions for Rundfix, time-and-materials or fixed-fee COMOS consulting engagements, and custom development projects for energy providers (Energieversorger), plant operators (Anlagenbetreiber), small and medium enterprises (KMU), and plant planners (Anlagenplaner) across the DACH region with growing international footprint. Go-to-market is dual-track: product-led growth through app stores and self-service for Rundfix, and enterprise field sales with consultative selling for COMOS and custom work. The firm remains very small (1-10 employees), is founder-led, has not raised external capital, and is structured as a Swiss GmbH.
