Data analysts who understand HR, payroll, and workforce compliance. Not generic BI contractors, but specialists who know what the numbers mean in an employment context.
“Since our very first meeting, Octagon supported us with everything we needed in the HR field.”
The problem
Generic strategy consultancies sell decks. Pure-data agencies sell dashboards. Neither specialises in HR-operational analytics inside a regulated employer. When the dashboard shows a spike in sick leave costs, a CAO compliance gap, a 30% ruling miscalculation, or a payroll variance across three countries, a generic analyst does not know what they are looking at. Octagon's analysts come from HR, payroll, and workforce operations across our five service pillars in six European markets, and work inside the data-residency rules that apply to aerospace, defence, and international-organisation clients. Our 39+ years of operating experience and 35+ nationalities on staff shape the analytics patterns we build.
Why HR data is different
HR data is not like sales data or marketing data. It involves multi-country payroll with different tax regimes, sick leave obligations that span 104 weeks, pension contributions governed by sector-specific CAOs, and workforce metrics that must account for contract types, probation periods, and dismissal protections.
An analyst without HR domain knowledge will produce dashboards that look right but contain errors that surface first during an audit or a dispute. Octagon's data team brings 39+ years of HR operations experience to every engagement, and works inside the calculator suite that underpins our HR consultancy, so every number shown ties back to verifiable working.
From discovery through to delivery and handover.
The typical approach
No continuity. No domain knowledge. No accountability.
The Octagon approach
1 partner. HR expertise. Full accountability.
Playbook
Four phases from audit through to operational handover.
Discovery
1-2 weeksWe audit your current HR data sources, reporting gaps, and decision-making workflows. We identify what metrics your leadership needs and where the data lives today.
Recruitment
3-6 weeksWe source and recruit HR data specialists with the right blend of technical skill (Power BI, SQL, Python) and domain knowledge (payroll, workforce planning, employment compliance).
Employment and onboarding
1-2 weeksEvery analyst is employed by Octagon on a compliant contract. We handle payroll, pension, social security, and all statutory obligations. They start working inside your team from day one.
Delivery and handover
OngoingOur team builds, tests, and deploys your dashboards, reports, and analytics tools. We document everything and train your internal teams so the capability outlasts the engagement.
Employment and compliance
Every data specialist we place is employed on a compliant Dutch or European contract. We handle payroll, pension, social security, 30% ruling administration, and all statutory obligations. Your team gets the analyst; we handle everything else. For multi-country engagements, we provide the same employment quality across the Netherlands, United Kingdom, Germany, France, Italy, and Cyprus under a single contract.
Four specialist domains where we build and deliver HR data and analytics capabilities.
Workforce analytics, payroll variance, retention modelling, diversity metrics. Not general BI applied to an HR dataset, but analytics designed around the employment rules that govern the numbers.
Aerospace, defence, and international-organisation clients carry data-residency and handling rules that generic agencies fail on quietly. Our analysts work inside those rules by default.
Where Octagon runs your recruitment and EOR, the analytics pull from the same operational data stream we are already maintaining. One provider across sourcing, employment, and analytics, rather than three.
Our analysts understand wage tax tables, social security contributions, CAO obligations, holiday allowance calculations, and sick leave timelines. They read the numbers in their employment context.
Dashboard figures are reconciled against our in-house calculator suite for transition payment, WKR free space, pension contribution, and net pay under the 30% ruling. Every number shown is a number we can stand behind.
Every dashboard accounts for regulatory requirements: Wet Poortwachter timelines, GDPR data handling, pension fund reporting obligations, and Works Council information rights.
Every engagement has a named account manager who knows your programme, your people, and your HR priorities. Not a ticket system.
