Munich · Software engineering since 2000
Engineering intelligent and advanced computing systems
Quantag develops production-ready AI, machine learning, GPU, cloud, quantum and secure IoT solutions — from research and architecture to deployment.
Capabilities
Five pillars, twelve disciplines
Each pillar groups the work that actually ships together. Research, architecture and deployment stay with the same team throughout.
Intelligent Systems
Models and automation in production
Artificial Intelligence
Build generative AI, computer vision, AI on premises, language and intelligent automation systems around real business workflows.
Machine Learning
Turn data into deployable models for prediction, classification, optimization and decision support.
Advanced Computing
Compute-heavy and emerging platforms
HPS Computing
Design and operate scalable GPU infrastructure for model inference, training and computationally intensive workloads.
Quantum Computing
Explore and implement hybrid classical–quantum solutions, algorithms, simulations and development environments.
Secure Connected Systems
Devices and cryptography that hold
IoT & Embedded Systems
Connect devices securely with embedded software, firmware, communication protocols and cloud services.
Post-Quantum Cryptography
Prepare software and infrastructure for quantum-safe security through assessment, migration and integration.
Cloud Engineering
The platform everything runs on
Cloud Platforms
Develop resilient cloud-native platforms, distributed services, APIs and automated deployment infrastructure.
Backend Engineering
Build reliable APIs, data services, authentication systems and high-performance distributed backends.
Full-stack Engineering
Included on every project
Web Development
Build multi-layer web applications with responsive interfaces and test coverage that holds up in production.
Backend Development
Develop application backends, APIs and data layers for the web and mobile clients that sit on top of them.
Mobile Development
Ship native and cross-platform mobile apps, from lightweight clients to low-level device integration.
Desktop Development
Build desktop software for Windows, Linux and macOS, including the system-level work it depends on.
How we work
Agile delivery you can inspect
Scrum delivery
Work runs in short iterations, each one ending in something you can run and judge for yourself.
Estimates in the open
Scope and effort are broken down before anyone commits, and revised in front of you when reality moves.
Direct access
The engineers building the system are the people you talk to about it. No relay layer.
Track record
Founded in 2014, out of a software division that had been building for German industry since 2000.
Firmware, drivers, compilers, mobile platforms — then cloud services, and now AI, GPU and quantum systems. The technologies moved on; the engineering standard the work is held to did not.
