Client stories
For 39 years, organisations across aerospace, defence, and international affairs have trusted Octagon to deliver their most critical workforce needs.
Partnerships built on performance
Octagon does not chase one-off placements. We build long-term partnerships with organisations that demand consistent quality, deep compliance knowledge, and sector-specific expertise. Many of our client relationships span over a decade, and several go back to our founding years.
The organisations we serve operate at the highest levels of complexity: space agencies managing billion-euro programmes, international courts handling cases of global significance, defence primes requiring security-cleared personnel, and technology companies scaling across borders. In every case, the workforce is mission-critical and compliance is non-negotiable.
Octagon has been our trusted partner for workforce services for over fifteen years. Their understanding of our sector, combined with their compliance rigour and genuine care for the professionals they place, makes them indispensable to our operations in the Netherlands.

Scaling a classified multi-country workforce
A major aerospace programme needed to scale a multinational engineering team of 200+ contractors across classified programmes in three European countries, each with different employment law, security clearance requirements, and social security frameworks.
Octagon managed recruitment, compliant employment through EOR, multi-country payroll processing, and security clearance administration across all three countries. Every contractor was employed under the correct local framework with full statutory compliance. All positions were filled within programme timelines across a partnership spanning more than 30 years.
From zero to operational in six weeks
An international technology company needed to establish a Dutch hub with 50+ professionals from 12 nationalities. Each hire required HSM visa sponsorship, 30% ruling applications, and compliant Dutch employment contracts, all within an aggressive six-week timeline.
Octagon acted as the Employer of Record, handling employment contracts, visa processing through our IND Recognised Sponsor status, 30% ruling applications, relocation support, and monthly payroll from day one. Team fully operational within 6 weeks. All visa and tax rulings secured.
Staffing a treaty-based organisation
A treaty-based international organisation needed to fill cybersecurity and data analytics roles under a complex employment framework involving privileges and immunities, host-country agreements, and multi-national payroll obligations.
Octagon built a specialist recruitment pipeline with compliance expertise spanning diplomatic employment frameworks, multi-national payroll, BSN registration, and ongoing HR support for locally recruited staff. Framework agreement established. Consistent delivery of cleared, qualified professionals across operational divisions over multiple years.
Eliminating contractor misclassification risk
An international organisation operating in the Netherlands had been engaging a significant portion of its workforce as independent contractors. Under the Wet DBA and upcoming VBAR legislation, this exposed the client to substantial back-payment obligations, tax penalties, and reputational risk with Dutch authorities.
Octagon conducted a full workforce classification audit, identified roles that fell outside the legal definition of self-employment under Dutch law, and transitioned affected workers to compliant employment contracts through our EOR service. We restructured the engagement model, implemented ongoing classification monitoring, and trained the client on Dutch labour law obligations. All misclassified engagements resolved before enforcement began.
Security-cleared talent for classified programmes
A classified defence programme required 80+ security-cleared professionals across multiple European sites, with strict AIVD/MIVD vetting timelines and national security constraints that standard recruiters could not navigate.
Octagon managed the full recruitment pipeline with sector-specific sourcing, coordinated the security clearance process with national intelligence services, and provided compliant employment through EOR across both jurisdictions. All positions filled within programme deadlines. Ongoing partnership across multiple classified programmes.
Multi-country payroll consolidation
A growing technology company was managing payroll through separate providers in four European countries, leading to inconsistent reporting, missed statutory deadlines, and duplicated administration costs.
Octagon consolidated all payroll operations under a single point of contact. We standardised payroll calendars, unified reporting formats across jurisdictions, and integrated pension and social security administration into one streamlined process. Single monthly invoice replacing four separate vendor relationships.
