Sebastian Janus
Founder & Managing Director
Blackshield is built around one conviction: technology only creates value when it is architected, not just installed. With roots in cryptography and software development, Sebastian pairs deep technical understanding with strategic business thinking — and helps companies turn AI and automation into measurable growth.
His work bridges deep tech and business strategy: building operating models and systems that turn scattered tools into clear workflows and real ROI. No hype — just the structure that moves the P&L.
