Precision in global talent. Excellence in leadership.

Three principles govern every mandate. They are neither aspirational nor negotiable.

Absolute Discretion

Confidential search execution across sensitive board and C-suite transitions. GDPR-first architecture, PDPA and PDPL corridor discipline, no candidate representation to unnamed clients.

Direct Partnership

No account-manager shuffle, no proposal panels. You work with the principal who runs the mandate — from brief through onboarding, and through the first two board meetings.

Corridor Advantage

Access to passive technical leaders across European, Gulf and APAC ecosystems that local databases never surface — deployed into high-growth hubs without the local talent-scarcity premium.

The name means 'search' in Esperanto — a language built to belong to no single country. Neither does this practice.

Partners who author our research execute our mandates.

A small, focused team. The principals writing our insights are the same people conducting your search.

Sercxi's partners have led technology mandates across these corridors since 2000 — a quarter century of cross-border networks behind every shortlist.

Candidate SLA

We do not represent candidates to unnamed clients.

No professional data or CV moves without explicit, trackable written consent.

Harald H.R. Agterhuis

Founder · Amsterdam · Dubai

Who I serve

Works across all corridors. Thirty years placing technology executives across APAC and EMEA, personally, mandate by mandate.
Harald doesn't hand off a mandate — he signs it, works it, and closes it himself. Thirty years running cross-border technology searches across all corridors have taught him that most job briefs are wrong until tested; he reworks them before he starts. The discipline shows: a 35-day median shortlist and eight in ten placements still in role after a year. Clients call him one of the most trusted names in the search industry. Considering a mandate? Ask Harald what he'd change about the brief first.

Ir. Gerard Elkhuizen MBA

Partner · Business Technology & Transformation · The Hague

Who I serve

Forty years shaping, selling and delivering the large transformation programmes that decide whether new technology becomes new capability.
Gerard has spent forty years shaping deals that decide whether new technology becomes new capability — or an expensive shelf item. At Cognizant, the Benelux team he built generated roughly half the unit's revenue run-rate; at Deloitte, he ran a €100 million global transformation programme. Trained as a civil engineer before turning to consulting, he now leads Sercxi's Business Technology and Transformation mandates from The Hague, judging hires the way he once judged deals — by whether they hold up under scrutiny. Talk to Gerard before you write the brief.

Peter van de Graaff

Partner · Executive Hiring Lab · Amsterdam

Who I serve

Calm in crisis, sharp in strategy — most leadership problems are clarity problems dressed up as talent problems.
Peter spent twenty-five years as a COO, CHRO and board member learning that most leadership problems aren't talent problems — they're clarity problems wearing a talent problem's clothes. He's run people strategy at a twenty-billion-dollar agribusiness, sat on the board of a $1.6 billion investment group, and co-founded the Dutch career consultancy trusted by KLM, Heineken and ASML. Now he runs Sercxi's Executive Hiring Lab from Amsterdam, refusing to open a search until the brief survives scrutiny. If your last hire didn't work, start with Peter, not the job description.

Peter Post

Partner · Digital Talent Sourcing · Amsterdam

Who I serve

Old-school recruiting instinct, modern stack, engineer's discipline — pipelines built before the brief is signed.
Peter reads a CV the way an engineer reads a system diagram — which makes sense, since he spent thirteen years building logistics and telecom systems before search claimed him. Now he runs Sercxi's sourcing stack, a ten-platform pipeline spanning Greenhouse, Loxo and LinkedIn Navigator, the one that found Cloud, AI and cybersecurity engineers for a Gulf government-scale mandate at national-programme speed. He builds the pipeline before the brief is even signed. If your role calls for sourcing to already be underway, Peter is the one to speak to.

Tony Boersma

Partner · Business Development & Executive Recruitment · The Hague

Who I serve

He does not send a longlist, he sends the hire — Tier 2 and Tier 3 operators for the EMEA digital infrastructure build-out.
Tony doesn't send a longlist — he sends the hire. Twenty-five years building talent systems across thirty-plus countries taught him that growth always outpaces the operators needed to run it, especially in digital infrastructure. At Core42 he cut executive deployment from ninety days to ten; at Trivium Packaging he built a global talent function from nothing, twenty countries deep. Trained in law before recruitment claimed him, he now secures the Cloud Architects and Data Centre specialists EMEA's build-out depends on. Bring him the gap, not the job spec.

The Interval

The principal who takes your call is the principal who runs the mandate. No handoffs, no associates, no proposal panels.

Initiate Confidential Briefing

Secure calendar allocation — active or impending cross-border mandates only.

Three steps. No ambiguity. No handoffs.

Three phases. No mystery. The difference is in the depth of preparation, not the complexity of the framework.

Understand the Gap

Before we source a single candidate, we map the strategic context. What capability is actually missing? What technical debt is the hire meant to liquidate? Most briefs describe a role. We identify the economic problem the role needs to solve.

Work the Corridors

Our EMEA-APAC networks surface candidates the market hasn't priced correctly. We combine agentic systems with deep conviction - because algorithms find CVs, but judgement finds leaders.

Deliver & Measure

A placement without integration is a transaction. We measure success at twelve months, not twelve days. Faster timelines because deeper preparation - not because we cut corners.

Every mandate follows this framework. Every partner owns it start to finish.

The Brief Determines the Outcome.

Tell us what this hire needs to unlock. Not the job title, the organisational problem.

Three candidates, every one we would hire ourselves.
