vensas GmbH

vensas GmbH is a software engineering company in Saarbrücken, Germany. We build custom software for mid-sized companies in the DACH region. Managing directors Sascha Kiefer and Sven Hennessen write code on client projects themselves. Every project is staffed by senior developers who handle both the concept and the code. We don't offshore any of the work.

Most of our clients run their business on systems that have grown over the years: an ERP, a few internal tools, and often a .NET application that is older than anyone wants to admit. We connect these systems, modernise them step by step without downtime, or replace them when that makes more sense. Typical work includes production control and MES, order and capacity planning, quality inspection processes, shift planning, and the integrations between them.

We also help companies use AI in production instead of stopping at a demo. That covers GenAI and RAG integration, AI agents, AI-driven process automation, and AI readiness checks. Where data sovereignty matters, we run AI on EU or on-premise infrastructure.

Other services: code and security reviews, technical due diligence, software architecture, DevOps and cloud (Azure, AWS, on-premise), legacy modernisation, and developer training.
