Customer Success Manager Recruitment Agency

Archetype recruits customer success managers for B2B companies, including tech businesses, that want to keep and grow their existing clients in Belgium and the Benelux. We first check that your need really is customer success, then assess each candidate on the real figures of their portfolio and with the KOAN test. The assignment runs on a retainer, with fees set before the search starts in a written proposal, and takes 12 weeks on average. A 6-month replacement guarantee applies, and we recruit in French, Dutch and English. Tell us about the role to receive a proposal within 48 to 72 hours.

Customer success manager in an account review with a client in a B2B office — A CSM is judged on the figures of their portfolio: retention, adoption, renewals.

Before you hire: CSM, customer support or account manager?

The title “customer success manager” covers very different jobs from one company to the next. Before we start a search, we check with you that your need really matches this role. Three functions look alike on paper and are often blurred in job adverts.

Role	Day-to-day work	What they must prove
Customer support	Handles incoming requests and resolves incidents	Response times, tickets resolved
Customer success manager	Tracks product usage, spots at-risk accounts, prepares renewal and expansion	Retention, adoption, expansion revenue
Account manager	Grows revenue across a portfolio, negotiates pricing and renewals	Portfolio growth, margin

If your priority is answering tickets faster, a CSM will not fix it, and we will tell you so on the first call. We set out that boundary in our article on the difference between customer support and a customer success manager. When the role leans towards pure selling, our account manager recruitment page is a better fit. A CSM is a farming role: they grow existing clients rather than hunt new ones, a choice to settle before you write the job advert.

Our first call isn’t about validating your brief. It’s about challenging it. Most agencies take the order, go sourcing, and come back with ten CVs. We put the requirement back on the table first: is the role properly defined, does the scorecard hold up, is the market aligned with your range? If the brief drifts, so does the sourcing. This discipline isn’t comfortable for everyone, but it’s what’s kept us in business for 33 years.

How we assess a customer success manager candidate

A CSM is judged on results achieved with their current clients. At interview, we ask for precise figures and how they got them. Our article on the essential KPIs for a customer success manager lists the ones we check: churn, net revenue retention (NRR), health score, adoption rate and expansion revenue. A candidate who does not know the numbers of their own portfolio has already told us something.

Every candidate we present goes through three stages:

an in-depth interview on their current portfolio: number of accounts, contact rhythm, renewals won and lost;
a competency analysis against the role scorecard, agreed with you at the start of the assignment;
the KOAN personality test, the tool we have used for thirty years. For a CSM, we look first at customer orientation, responsiveness, perseverance and influencing strategies.

For each candidate you receive a structured file: scorecard, interview write-ups and the KOAN reading. The same approach, with a role-play or case study built on your situation added, is also available outside a search assignment, when you are torn between two finalists: see our assessment for recruitment.

Timeline, fees and guarantee

We work on retainer only, never on contingency. You commit, and we see the assignment through, however long it takes. A typical assignment runs as follows:

Stage	When	What happens
Discovery call	Day 1	Needs analysis, the role is challenged, proposal promised within 48 to 72 hours
Assignment signed	12 days on average after first contact	Brief summary, scorecard, sourcing strategy, employer branding proposal
Candidate shortlist	During the assignment	Detailed candidate files: scorecard, interview write-ups, KOAN reading
Placement	12 weeks on average after signing	Candidate signs
Onboarding	First 3 months	Follow-up with the candidate and their manager. 6-month replacement guarantee

The fee is set before the search starts, in the written proposal you receive after the discovery call. The amount depends on the languages required, the management level, the technical complexity of your product and the complexity of the assignment. More than 75% of our assignments end in a placement; those that do not are stopped by the client.

Frequently asked questions about hiring a customer success manager

How much does a recruitment agency charge to hire a customer success manager?

At Archetype, the amount depends on the languages required, the management level, the technical complexity of your product and the complexity of the assignment. It is set before the search starts, in a written proposal sent within 48 to 72 hours of the first call. We work on a retainer, without a success fee, with a 6-month replacement guarantee.

How long does it take to hire a CSM?

Allow 12 weeks on average between signing the assignment and the candidate signing. The assignment itself is signed 12 days on average after the first call.

What is the difference between a customer success manager and an account manager?

A CSM tracks product usage and account health to secure renewal and open up expansion. An account manager leads the commercial negotiation and grows portfolio revenue. In smaller companies one person sometimes does both, which needs to be settled before the job advert is written.

What salary should you offer a customer success manager in Belgium?

It depends on seniority, languages, sector and the share of variable pay tied to retention. We set out the ranges and the package structure in our article on customer success manager salaries in Belgium. If your range is out of line with the market, we tell you before the search starts.

How do you assess a customer success manager at interview?

Ask for the figures of their current portfolio (churn, NRR, renewals) and how they achieved them, then put them in a scenario with an at-risk account. At Archetype, the in-depth interview is backed by a competency analysis against the role scorecard and the KOAN test.

What happens if the CSM leaves the company?

We offer a 6-month replacement guarantee. We also follow up with the candidate and their manager during the first three months, because that is when onboarding succeeds or fails.
