How exactly does the hiring guarantee work?

We fill the agreed role - what "fit" means we define together in writing beforehand. If it does not work out, we keep going at no further agency cost, or we replace the hire. There is no money back, your ad budget keeps running with you. Condition: you interview promptly and do not turn down suitable candidates without reason.

What is this feasibility check?

Before we take on a role, we check whether it is realistically fillable in the current labour market - role, region, terms. We only accept roles that can be filled. That honesty up front is the basis for being able to guarantee at all.

Do you fill trade roles as well as salaried positions?

Both. From the skilled worker and foreman on site to the site manager and project manager in the office. For every role we clarify up front, in the feasibility check, what the market allows.

What is the difference from temp staffing or a staffing agency?

Temp staffing rents you people who never belong to you. We fill permanently - the person is employed by you, the system stays with you. No running charge rate, no dependency, but your own crew and your own recruiting channel.

How quickly is a role filled?

That depends on the role and region. The placement sprint starts right after the feasibility check. The construction market is tight - so we say honestly up front what is realistic, instead of promising a date that will not hold.

What does it cost - and when does it pay off?

The price depends on the package and the number of roles. A single filled trade role saves 60,000 to 100,000 euros over the vacancy, a filled site manager a multiple of that - the investment typically pays for itself with the first placement.

Industry: Construction & Development

Tradespeople and site managers who start.
And stay.

You fill open roles on site and in project management - with a hiring guarantee. No applicant treadmill, no agency retainer. A recruiting system that belongs to you.

Let's talk See services

No obligation - no lock-in contract

In construction, a role stays open for 273 days on average - almost a year in which the work still has to get done. An unfilled skilled role costs you around 9,400 euros per month, 60,000 to 100,000 euros over the full vacancy. A missing site manager runs to 8,000 to 25,000 euros per month in delay and extra cost - because without them, whole projects start to slip.

Most try the next social-recruiting agency. It delivers applicants, not hires - and a retainer that keeps running while the site waits. Applicant volume does not build a house. The foreman standing on site on Monday and still there in a year builds it.

Blacklyne fills your open roles - trades and project management alike - with a hiring guarantee. We only take on roles that are realistically fillable after a feasibility check, and we build you your own recruiting system along the way: a careers page, employer visibility into AI search, a channel that belongs to you. 290 businesses have trusted the Blacklyne group since 2024.

WHERE IT HURTS

What kills inquiries in your industry.

Industry-specific pain points from daily operations.

273 days with the role sitting open

That is how long it takes on average to fill a role in construction. Almost a year in which your people cover the gap, overtime piles up, and jobs are still meant to finish on schedule.

Every unfilled trade role costs five figures

Around 9,400 euros per month, 60,000 to 100,000 over the full vacancy - as lost output, missing capacity and expensive bought-in subcontracting. A number no one sees on an invoice and everyone carries anyway.

A missing site manager sends projects sliding

Without them, deadlines shift, variations explode, coordination is missing everywhere. An unfilled site-manager role costs 8,000 to 25,000 euros per month in delay and extra cost - per project.

An applicant treadmill instead of filled roles

The agency sends contacts, you run interviews, and the site stays understaffed. Applicant volume is not a result. The person who starts and stays is.

The retainer runs, the role does not

You pay monthly for activity, not for hires. When the contract ends, the role is still open and you hold nothing that belongs to you.

New hires drop out in probation

Hired, onboarded, gone again. Recruit for volume instead of fit and you fill the role twice - carrying the ramp-up cost every single time.

THE NUMBERS

10 minutes late = half of them gone.

Prospects are impatient. If you don’t reply in seconds you lose them to the next agency. With the right system in place, you reply in under 60 seconds - every day, including Sundays.

WHAT CHANGES

Here is what changes for you.

Filled, with a hiring guarantee

We fill your open role - guaranteed in writing. If it stays open, we keep working at no further agency cost, or we replace the hire. Not money back, but the person who starts.

Only roles that can be filled

Before we start, a feasibility check confirms whether your role is realistically fillable in the market. We promise nothing the labour market cannot deliver - which is exactly why we can guarantee.

Replacement at no further agency cost

If someone does drop out or it does not fit in the end, we keep going - within the guarantee, with no new agency cost for you. Your ad budget stays with you, unchanged.

A system that belongs to you

No retainer lock-in. You get your own careers page and a recruiting channel that keeps running once we are done - instead of a dependency that never ends.

Visible where tradespeople search

Whoever asks Google or ChatGPT about construction work in your region lands with you. Employer visibility into AI search - where the good ones look first today.

A placement sprint for the urgent site

A role has to be filled now or the deadline wobbles? The placement sprint solves that one vacancy - fast, guaranteed, without immediately committing to a whole system.
