- **Founded**: 2020
- **Founders**: Elias Schneider (CEO), Thomas Weyand (COO), Christophe Attias (CTO), Roman Frolov (Co-Founder)

- **Mission or purpose statement**: "Empowering organizations to innovate faster while maintaining control" — enabling users of all skill levels to develop and manage complex software across all environments.

## Products & Services
- **The Virtual Cloud Platform**: A sovereign platform layer that decouples compute from runtime, standardizes network storage, and removes Docker complexity. It can be installed on any infrastructure (air-gapped, on-prem, cloud, hybrid) and includes patented cold-start deployment technology, zero-config autoscaling, self-service CI/CD, and managed services.
- **Deployment Technology**: Patented deployment algorithm that eliminates Kubernetes knowledge requirements, enabling teams to deploy anything from simple frontends to multi-service production landscapes and LLMs.
- **Workspaces & Integrations**: Developer-centric self-service environment for end-to-end infrastructure management.

## Competitive Advantages

- **Sovereign by Design**: EU-first, vendor-neutral, and can operate in air-gapped environments — critical for regulated industries like banking and public sector.
- **Patented Deployment Technology**: Eliminates the need for Kubernetes expertise, reducing operational complexity and the DevOps talent bottleneck.
- **Cost Reduction**: Claims 40-60% reduction in total cost of ownership across infrastructure, personnel, and licenses.

## Strategic Focus
- **Digital Sovereignty**: Capitalizing on growing regulatory and geopolitical risks (trade wars, supply chain disruptions) to offer infrastructure independence.
- **Regulated Industries**: Deepening presence in banking, public authorities, and other restricted verticals where compliance and security are paramount.
- **AI Workloads**: Enabling production AI workloads (including LLMs) on their platform, even in air-gapped environments.
- **Enterprise Adoption**: Scaling from mid-market to large enterprise, with a focus on migrating legacy infrastructure without specialized DevOps resources.

## Why Work Here
- **Culture & Mission**: Purpose-driven work focused on solving infrastructure dependency and digital sovereignty — a high-impact, meaningful challenge in European tech.

- **Engineering Excellence**: Strong engineering pedigree rooted in Baden-Württemberg, Germany's high-tech hub. Technical team makes up 31% of headcount. Focus on patented, novel technology (not just "cloud wrapping").
