Oliver Keizers

I build regions, teams, and revenue from the ground up.

At Semperis, I launched the EMEA Central region with zero brand awareness, no customers, no partners, and no local team. Within four years, this operation generated +$13M in ARR, driven by a focused team of 7 quota-carrying AEs supported by marketing, channel, presales, and post-sales resources.

My focus is complex enterprise sales in regulated industries: G2K, critical infrastructure, and financial services. I combine strategic thinking with pragmatic execution — from market entry to ramp-up to scale.

I manage from the field, not from behind a desk. I work closely with my team, customers, and partners on the ground — coaching in live deals, opening doors, and ensuring we learn fast and execute even faster. In early-stage environments, that’s where speed, trust, and outcomes are built.

I hire with intent. My network spans DACH, Alps, Nordics, and Benelux, and I understand why seemingly strong hires often fail. I prioritize resilience, speed, and reliability over CV keywords.

My specialization is in Cybersecurity, identity-first security, ITDR, and enterprise-grade resilience — topics that require board-level understanding and alignment.

Core strengths:
- Market entry and GTM execution
- Enterprise pipeline generation and sales execution
- Hiring and building high-performing regional teams
- Partner and channel strategy
- Trusted advisor to G2K customers and their CISOs
