Leadstars ran the Job Acquisition Machine (candidate acquisition) for Bureau In Techniek, targeting Mechanical & Electrical Engineer in Gelderland, Overijssel, North Brabant during 22 May - 21 Aug 2025. The campaign ran through Meta Ads + AI sourcing + CV tool and recorded candidates 107, cost per lead € 30.51 and applications 59. These are campaign figures taken straight from the ad platform and funnel reporting for this campaign: reach, cost per lead and volume. They say nothing about placements, hires or revenue, and Leadstars does not report those.

We ran three channels side by side: Meta ads into an application funnel, AI sourcing, and a CV tool on existing databases. The ads produced 59 funnel applications, AI sourcing added 29 candidates at roughly a 35% response rate, and the CV tool a further 19. With almost three quarters of traffic on mobile, the funnel was built mobile-first. The first applications came in within 24 hours of launch.

Assumptions
- Applications in this case: 107
- Your placement rate: 10%
- Contract staffing (detachering) - gross margin per professional per year: € 30,000 (€ 30,000 × 1 year)
- Ad spend in this case: € 1,800
Source: A contract professional costs a client EUR 81.02 per hour on average (VvDN MarktMonitor Q2 2026). The contract staffing firm's margin commonly runs at 20-30% of that rate, or EUR 16 to EUR 24 per hour. At roughly 1,700 billable hours per year that is EUR 27,000 to EUR 41,000 gross margin per year, per professional. Contract staffing assignments often run longer than a year.
This is a model, not a realised result. Adjust the assumptions to your own margins and placement rate.
