Headhunting, RPO or in-house: how to choose

The three modes, in plain terms

Before you can decide, you need to define what each mode covers. Three logics, three terrains:

In-house hiring: your Talent Acquisition team recruits with your own tools, your ATS and your employer brand. Everything happens internally, from defining the need to signing the offer.

RPO (Recruitment Process Outsourcing): you outsource all or part of the process to a provider who lends you their capacity and method for the length of an engagement. They work under your colours, usually at volume.

Headhunting (direct approach): a firm identifies and approaches rare profiles individually, people already employed who aren't actively looking. One role at a time, and confidentially if needed.

None is better in absolute terms. They answer different needs, and they lose all their effectiveness the moment you put them on the wrong role.

Why the choice of mode changes everything

Because the mode decides the timeline, the cost and the quality of the profile. The talent market has been tight for several years now:

12 weeks on average to hire a manager, up to 15 in industry (APEC, 2024)

One company in two that hired a manager in 2025 ran into difficulties, 15 points fewer than in 2022 (APEC, 2026)

The gap between applications received and the profiles sought is now the number one difficulty (75%), ahead of a shortage of applications (73%) (APEC, 2026)

So the market has eased, but the difficulty has changed in nature: it's no longer the volume of applications, it's the targeting. On the recruiter side, volume has in fact exploded without the relevance: a recruiter now handles around 5,300 applications a year, 77% of which aren't relevant, up 93% on 2021 (Welcome to the Jungle, 2026).

And for the most sought-after profiles, the job ad no longer cuts it: directly sourced candidates are nearly eight times more likely to be hired than inbound applicants, and direct sourcing delivers 11% of hires from just 2.6% of applications (Gem, Recruiting Benchmarks 2026, 165 million applications and 1.2 million hires analysed). Those profiles are already employed and only respond to a precise, personalised approach. That's exactly headhunting's terrain. Choosing the wrong mode means stretching the timeline and missing the best candidates.

No best mode, only a fitting one

The real question isn't "headhunting or in-house?", but "which mode for this role, in my context?". A team hiring ten junior profiles a year and a single strategic director don't have the same need.

Our conviction: AI has put mass outreach within everyone's reach, so the human, targeted approach becomes rare and decisive. AI for sourcing speed, humans for closing the profiles everyone's fighting over. The mode is chosen on criteria, not on habit.

When to choose what

In-house hiring. When you have steady volume, an employer brand that attracts and a tooled-up TA team. The cheapest per hire, provided you have the machine and the inbound flow.
RPO. When you have a volume spike over a set period (fundraising, scale-up, new site) without wanting to staff a full TA team. You're lent the capacity and the process, for as long as needed.
Headhunting / direct approach. When the role is rare, strategic, confidential or scarce, and the best are already employed. The most expensive per hire, the most effective on profiles you can't reach any other way.

The 5 decision criteria

Role scarcity. Common and available profile, or scarce and already employed? The rarer it is, the more headhunting imposes itself.
Volume. A single role, or ten hires this quarter? Volume points to tooled-up in-house or RPO.
Urgency and stage. A one-off critical need, or a flow to install over time? Your company's stage changes the answer.
Internal capacity. Do you have the team, the tools and the time? Without an internal machine, an ad alone won't convert.
Confidentiality. A sensitive replacement, an unlisted role: headhunting lets you approach without exposing the need.

The 3 modes in one table

Mode	Cost (order of magnitude)	Ideal for	Benefits	Risks
In-house	Structure cost: TA team salaries, ATS, sourcing licences, job boards, employer brand. Dilutes once the volume is there	Steady, predictable volume, common roles, already mapped job families, repeat hires on the same profile	Deep knowledge of the business, the culture and the managers; lowest cost per hire as soon as volume follows; compounding assets over time (talent pool, network, referrals, process data); full control of the candidate experience	Without an expert TA team, a structured hiring process and an employer brand, quality inbound doesn't work and conversion stays very low
RPO	Monthly flat fee or per hire, depending on the volume and length of the engagement	Volume spikes, scale-up, new site, ramping up over a few months without staffing a full TA team	Hiring capacity live within days; process, tools and reporting ready to use; cost per hire that drops with volume; a reversible commitment that follows the actual workload; method transferred to the team in place	Lack of stability and of trust towards an external partner
Headhunting	20 to 30% of the profile's annual package	Expert, rare, strategic or confidential roles, when the right candidates don't answer job ads	Access to passive candidates, who make up most of the qualified pool; individual and confidential approach; market expertise and salary benchmark; controlled timeline on profiles you can't reach any other way; replacement guarantee if the hire fails	Poor understanding of the business, support often limited to one or two hires

For reference: in-house, hiring a manager costs on average €5,000 to €12,000 in direct costs, covering ads, sourcing tools and the time spent by HR and operational teams, excluding firm fees. A headhunting engagement is billed around 20 to 30% of the hired profile's annual package (market practice). That price gap should always be weighed against the cost of a vacant role, or of a failed hire.

And often, it's a mix

Companies that hire well don't pick a side once and for all. They keep in-house for recurring roles, activate RPO on spikes, and bring in headhunting for expert, rare and confidential roles.

The decision is made role by role, based on priorities and on the bandwidth of the teams, and above all on budget.

Hence the need to plan a hiring roadmap, to anticipate and steer the workload on both recruitment and operational teams, especially in a growth phase.

That's exactly where a partner helps: putting the right mode on the right role, and installing the machine when it's missing.

Recruitment modes FAQ

Headhunting, RPO or in-house: what's the difference?

In-house hiring is your Talent Acquisition team recruiting with your own tools. RPO (Recruitment Process Outsourcing) hands all or part of the process to a provider who lends you their capacity and method, often at volume. Headhunting (or direct approach) targets rare profiles individually, people already in a job, through a specialised firm. Three different logics, for different needs.

When should you use headhunting?

When the role is rare, strategic or scarce, and the right candidates don't answer job ads because they're already employed. Directly sourced candidates are nearly eight times more likely to be hired than inbound applicants, and direct sourcing delivers 11% of hires from just 2.6% of applications (Gem, Recruiting Benchmarks 2026). For those profiles, posting an ad isn't enough, you have to go and find them one by one.

How long does it take to hire a manager?

In France, about 12 weeks on average, up to 15 weeks in industry (APEC, 2024). One company in two that hired a manager in 2025 ran into difficulties, 15 points fewer than in 2022 (APEC, 2026). The mode you choose (in-house, RPO, headhunting) directly affects that timeline and the quality of the final profile.

Can you combine several modes?

Often it's the best option. You keep in-house for recurring roles, activate RPO on a volume spike (fundraising, new site) and hand rare or confidential roles to headhunting. The point isn't to pick a side, but to assign the right mode to the right role.
