Voith GmbH

About

Voith is a 157-year-old industrial technology company operating critical infrastructure at serious scale: its turbines generate a quarter of the world's hydropower electricity, its paper machines produce much of the global supply, and its drive systems move rail, road, and maritime transport worldwide. With €5.2 billion in annual sales and 22,000 employees across 60+ countries, the attack surface spans legacy mechanical systems now being threaded with digital maintenance AI, cloud and edge compute layers, and operational technology stacks built on Siemens S7, PCS7, and SCADA/DCS architectures.

The threat model here isn't abstract. Hydropower turbines, papermaking lines, and marine propulsion systems are high-consequence targets where availability matters and safety interlocks are non-negotiable. Voith's OT environment includes PLCs, HMIs, and industrial control systems governed by IEC 62443 and NIST frameworks, with tooling like EPLAN for electrical design and SAP for enterprise integration. The company is pushing digital transformation - AI-based predictive maintenance, electric propulsion systems, decarbonization engineering - which means securing the seams between legacy hardware and modern connectivity.

Security engineering here means understanding both the physics of rotating machinery and the protocol-level risks in Codesys-based controllers or edge-deployed inference models. It's industrial automation defense where downtime costs are measured in megawatts and production tons, not just SLA percentages. Family-owned and German-headquartered, the organizational posture leans toward engineering rigor over fast iteration, but the infrastructure they defend powers cities and supply chains - making it a meaningful place to operationalize security at industrial scale.

Vosyn

In 2023, Vosyn emerged from a powerful insight: language barriers were preventing genuine human connection in an increasingly globalized world. The founders recognized that existing translation solutions fell short - they flattened meaning, stripped away cultural nuance, and failed to capture the human essence of communication. This gap inspired them to build something revolutionary: an AI-powered platform that could truly understand and preserve the richness of human expression across borders. What began as a vision to dissolve language barriers quickly evolved into VosynCore, a groundbreaking multimodal Large Language Model capable of real-time voice and text localization across 120+ languages while preserving tone, dialect, and emotional authenticity. From enabling a grandmother in Mexico to converse with her grandson in perfect Spanish to helping fans experience Japanese anime without losing its artistic essence, Vosyn has transformed from concept to a global movement - proving that technology, when designed with humanity at its core, can unite rather than divide us.

Westernacher Solutions GmbH

Westernacher Solutions builds digitization infrastructure for Germany's judiciary and public sector - electronic mailboxes for lawyers, semantic text analysis for courts, and secure communication systems that handle sensitive legal documents and citizen data. With over 160 engineers and domain specialists operating from Berlin, Heidelberg, and Bad Kreuznach, the company deploys systems under ISO 27001, BSI IT Grundschutz, and NIST frameworks for clients including federal and state ministries, courts, notary chambers, and legal professional organizations. The threat model is specific: preserving digital identities and maintaining confidentiality in systems where compromise means exposure of legal proceedings, attorney-client communications, and government administrative data. The technical stack centers on cloud security hardening, formal threat modeling, and compliance architectures built for environments where data protection isn't negotiable. Products like their electronic lawyer mailbox system require cryptographic messaging protocols and access controls that meet both legal profession standards and government security baselines. Teams work across legal tech modernization, public sector IT transformation, and NLP-driven document analysis - domains where security engineering intersects with regulatory requirements and operational continuity for institutions that can't accept downtime. Projects involve software modernization of legacy systems while maintaining security postures that satisfy both technical audits and legal mandates governing court operations and government communications.

VMRay GmbH

VMRay builds sandbox technology designed to catch malware that evades signature-based and behavioral detection systems. Founded in 2013 by Dr. Carsten Willems and Dr. Ralf Hund, the company operates out of Bochum, Germany and Boston, Massachusetts, serving 300+ security teams including Fortune 100 enterprises and government organizations. The core product is a threat detection platform that combines malware sandboxing with phishing analysis - engineered specifically for environments where unknown or evasive threats are the primary concern. The technical approach centers on sandbox instrumentation that monitors execution at a level designed to surface obfuscated payloads and anti-analysis tricks. The team includes detection engineers and security researchers with collective depth in malware analysis, working in Python, C, JavaScript, and the ELK Stack. VMRay's platform is deployed in enterprise SOCs, government threat intelligence operations, and MSSP environments where speed and accuracy on zero-day samples matter operationally. The company employs over 100 people across its German and U.S. offices. Engineering roles span detection engineering, security research, and platform development. The team describes itself as technical-first, with internal pathways from early-career research contributors to project leadership. Work focuses on iterating against adversary tradecraft - reverse engineering new evasion techniques, tuning detection logic, and shipping updates that keep pace with attacker tooling evolution.

EWOR GmbH

EWOR GmbH runs a Berlin-based founder fellowship with a 0.1% acceptance rate, targeting entrepreneurs building transformative tech companies across AI, HealthTech, clean energy, and fintech. The program offers up to €500,000 in immediate funding per fellow, plus €300,000 in cloud credits distributed through 16+ partner companies. Founded in 2020, EWOR operates as a virtual-first, borderless ecosystem with weekly 1:1 mentorship from full-time unicorn founders - including builders from SumUp (€8B), Adjust (€1B exit), and ProGlove (€500M exit). The fellowship's operational model centers on direct sparring sessions between fellows and mentor-founders, rather than cohort programming or curriculum. EWOR claims its fellows have raised Europe's largest pre-seed rounds as first-time founders, with €13M in aggregate pre-seed funding secured and valuations reaching $3B within two years of joining. The program draws founders with academic credentials from MIT and Oxford, including nuclear scientists and PhDs, positioning itself as infrastructure for technical founders building at the edge of emerging domains. For cybersecurity founders, the threat model here is resource allocation: EWOR's structure assumes high-conviction bets on individuals rather than diversified portfolios, with mentorship bandwidth as the constraining factor. The cloud credit package suggests focus on compute-intensive projects - relevant for security tooling that requires large-scale testing environments, threat modeling simulations, or ML-based detection systems. The 0.1% acceptance rate functions as both brand signal and actual filter, though the €300,000 cloud allocation indicates they're backing founders who need infrastructure at scale, not just capital.
