The first is that the good ones know electricians you will never find on a job board, and on a ramp that is worth real money. The second is that they charge a 25 to 75 percent markup on every hour those electricians work, and they show the same electricians to the contractor bidding against you. AI recruiting, our category, gets described in equally lopsided terms, so this is an attempt at a fair comparison from a company that sells one side of it. The short version: agencies win on sourcing people who are not looking; AI phone screening wins on speed and ownership for the people who are applying to you; most contractors and operators in this market should run both, and the split is not complicated. Quick answer A data center staffing agency sources candidates from its own network and charges either a 25 to 75 percent markup on every hour worked or a direct-hire fee of 15 to 30 percent of first-year pay, according to markup analyses from The Resource Company and Rinvio. Agencies are strongest on passive senior talent, such as a commissioning lead who never answers job posts, and on delivering traveler crews at short notice. AI recruiting tools work the opposite side: Joy, Classet's phone screener, calls applicants who come to a contractor directly, within minutes of the application, capturing license class, medium-voltage and switchgear experience, travel and per diem expectations, then writing a summary into the ATS for a flat monthly plan starting at $249. Agencies fill roles nobody applied to. AI screening prevents losing the applicants who did. ## What each one does A data center staffing firm (Data Center TALNT, The Birmingham Group, Kelly's digital infrastructure division, and dozens of regional shops) employs recruiters who work a network: journeymen they have placed before, hall contacts, LinkedIn, and the resumes of everyone who ever applied to one of their reqs. When you give them a req, they call that network, submit candidates, and either bill an hourly markup (contract) or a fee on hire (direct). The value is the network and the labor of working it. An AI recruiting tool does not have a network. It has your applicant flow. When an electrician applies to your posting at 9pm, Joy calls them within minutes, runs a structured interview in their language (license and class, voltage classes worked, UPS and switchgear, commissioning, travel and per diem, start date), follows up when they name specific gear, and writes a summary with the recording attached into your ATS. Your superintendent reads it the next morning and decides who to call. Joy does not grade or rank anyone. The value is that the first conversation happens the same night, for each applicant, without a recruiter's calendar in the way. Those are different jobs. The confusion comes from both being sold as "staffing." ## Side by side Dimension Data center staffing agency AI phone screening (Classet) Where candidates come from Agency network and sourcing; passive talent Your postings, referrals, hall, careers page Cost 25–75% hourly markup, or 15–30% of first-year pay per direct hire Flat plan: Starter $249/mo (50 interviews), Scale $999/mo (250), ATS Sync from $1,995/mo Speed to first conversation Days; recruiter works the req during business hours Minutes; 88% of candidates complete the screen within 20 minutes of applying After-hours applicants Wait for the recruiter Screened at 9pm or 6am; 55% of applications arrive after hours Who owns the candidate The agency; conversion fees to hire direct You; summaries and recordings in your ATS Consistency Varies by recruiter Same structured questions for each applicant Passive senior talent Strong Not the job Twenty travelers by Monday Strong Not the job Payroll and workers' comp Agency carries it on contract labor You carry it (they are your hires) Contract terms MSAs, guarantee periods, conversion fees Month-to-month on Starter and Scale; annual on ATS Sync The cost rows are the ones people argue about, so here are the sources. The Resource Company's [2025 markup analysis](https://www.theresource.com/2025/10/27/average-staffing-agency-markup-in-2025/) puts staffing markups at 30 to 75 percent overall and direct-hire fees at 15 to 30 percent of salary by seniority. Rinvio's [construction benchmark](https://www.rinvio.com/blog/data-center-electrician-crew-cost-benchmark) puts construction staffing markups at 25 to 75 percent. Classet's pricing is on the [pricing page](/pricing). The worked numbers for a 50-person ramp, including the case where the agency is cheaper, are in our post on [data center staffing cost](/blog/data-center-staffing-cost). ## Where the agency wins **The commissioning lead who is not applying.** Senior controls and commissioning people, critical facilities managers, and medium-voltage foremen mostly do not answer job posts. They answer a recruiter who placed them last time. An agency's network is the only way to reach them, and a 25 percent fee on a $150,000 hire that would otherwise hold a finished hall out of service for a month is a bargain against STL Partners' [$14.2 million per month](https://stlpartners.com/press/delays-in-data-centre-construction/) of delay cost. **Twenty travelers by Monday.** When a phase pulls forward and you need a crew from another market on per diem, an agency that runs travelers across states, under reciprocity agreements like the ones Texas expanded this year, can deliver. Your applicant flow cannot. **Payroll you do not want.** Contract labor keeps a six-month crew off your books and off your workers' comp. For subs who ramp and shrink by phase, that alone can justify the markup. ## Where AI recruiting wins **The applicants you already paid for.** A data center posting in Northern Virginia, Phoenix, or Dallas–Fort Worth pulls applications. Those electricians and technicians are the cheapest hires you will ever make, and most contractors lose them anyway because the first callback comes a week later. Kelly's [2026 Data Center Salary Guide](https://www.kellyservices.com/press-releases/kelly-releases-2026-data-center-salary-guide-highlighting-compensation-hiring-trends-driven-by-ai-acceleration) found 25 percent of data center staff get hired away annually; the same people who apply to you are applying to your competitor, and the one who calls first wins. Recruiting firm Data Center TALNT [says](https://www.datacentertalnt.com/speed) the industry takes 126 days to fill a role. Joy's first conversation happens the night of the application. **Ownership.** Applicants Joy screens are in your ATS, tied to your req, with the recording. When the next phase opens or the next campus breaks ground, you call them first. An agency's candidates are the agency's candidates, and a conversion fee applies if you want one on your payroll. **Consistency at volume.** A ramp generating 400 applications a month cannot be screened consistently by two recruiters, and it does not need to be. Joy asks each applicant the same job-relevant questions, in 25 languages, and a person reads the summaries and decides. We wrote about how this changes [AI recruiting for construction](/blog/ai-recruiting-construction) more broadly; data center ramps are the extreme case. ## How contractors run both The split most of our data center customers land on is simple. Joy screens applicant flow: every electrician, pipefitter, and tech who applies to a posting gets a call within minutes, and the superintendent starts each morning from a list of screened conversations. The agency gets the searches: the commissioning lead, the critical facilities manager, the traveler crew for the phase that pulled forward. The agency's recruiters spend their hours on the work only a network can do instead of screening the applicants a machine can, and the contractor pays the markup where it buys something. Two things make the split work. First, tell the agency. A firm that knows it is not being asked to work the job-board applicants will price the searches honestly. Second, write everything into one ATS, whether that is Greenhouse, Workday, Lever, Bullhorn, iCIMS, or Classet's built-in candidate management, so the superintendent sees agency submittals and Joy summaries side by side and the next ramp starts from both. The row-by-row version of this comparison is on our [compare page](/compare/data-center-staffing-agency), and the full picture for GCs, MEP subs, and operators is on the [data center hiring page](/use-cases/data-centers). ## Common questions Is a data center staffing agency worth the markup? For roles nobody is applying to (commissioning leads, critical facilities managers, medium-voltage foremen) and for traveler crews on short notice, yes; the alternative is a delay that costs millions a month. For the electricians and technicians already applying to your postings, the markup buys nothing you cannot do faster yourself with an AI phone screen. Can AI recruiting replace a data center staffing agency? No, not for sourcing. AI phone screening works a contractor's own applicant flow and has no network of passive candidates, so it cannot produce a commissioning lead who never answers job posts or deliver 20 travelers by Monday under a state reciprocity agreement. What it does replace is the agency's role in screening the people who already applied, which on a ramp is most of the volume: a 50-electrician build typically generates several hundred applications through job posts, referrals, and the hall. Screening those with Joy costs a flat monthly plan rather than a 25 to 75 percent markup on every hour worked, and the candidates stay on the contractor's own requisitions in Greenhouse, Workday, Lever, Bullhorn, iCIMS, or Classet's built-in candidate management instead of the agency's database, where a conversion fee applies. What do data center staffing companies charge? Contract and temp labor carries a 25 to 75 percent markup on every hour, with skilled trades at the high end. Direct-hire placements run 15 to 30 percent of first-year pay, or $12,000 to $24,000 on an $80,000 technician. Temp-to-perm conversions add a fee. Classet's plans start at $249 a month with published pricing. Which data center recruiting firms are there? Several national and regional firms specialize in the space. Data Center TALNT and The Birmingham Group both publish data center recruiting research and place trades and technician roles. Kelly runs a digital infrastructure division and issues an annual Data Center Salary Guide, the source of the widely cited figure that 25 percent of data center personnel are hired away each year. Regional electrical staffing firms place journeymen on individual ramps in each market, and craft-labor providers such as Sterling Infrastructure, MasTec, Quanta, EMCOR, and Comfort Systems supply crews at scale. Ask any of them three questions before signing: how conversion fees work if you hire a contract worker directly, whether the same candidate is presented to competing bidders on your job, and what the markup is on skilled trades rather than the blended average. How do AI recruiting tools screen data center candidates? Joy calls each applicant within minutes of the application, in the candidate's language, and runs a structured interview covering license class and issuing state, voltage classes worked, UPS and generator paralleling switchgear, commissioning experience, NFPA 70E and OSHA status, travel radius and per diem expectations, and earliest start date. When a candidate names specific equipment, Joy follows up on it rather than moving to the next scripted question. The output is a structured summary plus a recording and transcript on the candidate record in Greenhouse, Workday, Lever, Bullhorn, iCIMS, or Classet's built-in candidate management. Joy does not grade, rank, or rate candidates. A superintendent or hiring manager reads the summary and decides who comes on site, which keeps the hiring decision with a person and the paperwork with software. ## Key points - Agencies source; AI screening works your applicant flow. They are different jobs sold under the same word. - Agencies charge 25 to 75 percent markups or 15 to 30 percent fees and keep the candidates; AI screening is a flat plan and the candidates stay in your ATS. - Agencies win on passive senior talent, short-notice traveler crews, and payroll burden. - AI screening wins on speed (minutes versus days), after-hours applicants, and consistency at ramp volume. - Run both: Joy on applicants, the agency on searches, one ATS for the superintendent. ## Next steps Compare the two row by row on the [compare page](/compare/data-center-staffing-agency), or [see how Joy screens your applicant flow](/demo) alongside whatever agency you already use.
