Rockstar🎓
Top SchoolDominik Schürmann is a security-focused entrepreneur and engineer with 11 years of experience building privacy-first products and tooling, currently serving as CEO & Co‑Founder of heylogin, a German-hosted password manager that leverages hardware-based end-to-end encryption and 2FA by default. He holds a Dr.-Ing. in computer science and has a strong research background in network security from TU Braunschweig, where he published extensively and supervised numerous theses. Dominik combines academic rigor with hands-on mobile engineering—he contributes to prominent Android open-source projects like Etar, OpenKeychain and F‑Droid, improving preferences, UI and cryptographic integrations. Previously he co-founded COTECH to deliver a hardware security SDK for Android, and consulted on cryptographic protocols for agencies such as BSI and ENISA. Comfortable switching between low-level crypto, Android NDK work and product leadership, he brings rare depth across research, open-source development and secure product delivery. An interesting facet: he builds usable security products that deliberately avoid master passwords, favoring hardware-backed authentication.
