We build complex technical systems for companies where reliability matters: regulated platforms, financial tools, and mission-critical applications. Founded in 2010, we specialize in translating complex domain requirements into scalable, reliable solutions across fintech, legal tech, compliance, e-commerce, and real estate. WHAT WE BUILD Fintech & Compliance Platforms Trading systems, payment integrations, KYC/AML automation, regulatory reporting, financial calculations, and compliance workflows. Examples- boxtrades.de - Box spread trading platform with EUREX data integration - wb-check.de - Automated transparency register compliance tool (first-in-market for German UBO verification) E-commerce & Marketplace Platforms Multi-vendor marketplaces, custom inventory systems, complex pricing logic, payment gateway integrations, and automated fulfillment. PropTech & Real Estate Platforms Property management systems, CRM integrations, market data automation, MLS integrations, document management, and client portals. Learning Management Systems Custom LMS platforms, course delivery systems, certification programs, complex user hierarchies, progress tracking, and content management. US → EU Market Entry Technical strategy for GDPR compliance, data localization, regulatory compliance, architecture review, and implementation support. WHY COMPLEX SYSTEMS? Most projects fail not from lack of technical skill, but from underestimating complexity. We work at the intersection of deep technical execution and domain expertise: partnering with legal teams, compliance officers, and business experts to build what off-the-shelf solutions can't handle.
