Two engineers. Decades spent operating trust infrastructure.
Sigill.ai is built by people who have run systems used for identity, compliance, and regulated workflows — across Signicat, Accenture, and House of Control. It comes from operating real systems under audit.
Three decades in technology, operations, and security — focused on making regulated systems actually work in practice.
From early roles in insurance and product management to leading operations at Signicat, Hallvard has been responsible for environments where uptime, compliance, and auditability are non-negotiable. More recently, he has led technology, security, and R&D at House of Control.
Background covers the full operating stack: leadership and team building; SaaS, PaaS and IaaS on public and private cloud; ISO 27001 and GDPR compliance; ITSM and customer success; agile delivery, procurement and budgeting.
Worked on ISO 27001 and ISAE 3402 audited environments. eIDAS, GDPR, Schrems II in production. Cloud platform strategy, operational excellence, ITSM, and customer health.
