Find staffing agencies by vertical, size, and job volume

Staffing is one of the few industries that advertises its own activity. The count of live roles an agency runs says more about its size than any revenue estimate you can buy.

Posting volume is the honest size signal in staffing. A twenty-person agency running four hundred open requisitions is a bigger buyer of workflow software than a sixty-person firm placing a dozen executives a year. Start from what they advertise and work backwards to the firm.

TheirStack carries the posting side. Open Web Ninja and People Data Labs fill in the business: offices, headcount, founding year, and the brand behind a multi-office group. Blitz API runs the email column first, and LeadMagic takes the rows it could not resolve.

Posting counts move week to week, so the number belongs on the row with a timestamp rather than in your head. Re-run the column later and the table shows what changed instead of overwriting it.

Example searches

Ask for it the way you'd say it

Every search below runs on the same hosted Tables, with the cost previewed before anything is spent.

  • By what they place

    agencies placing healthcare and allied clinical roles, not general recruitment firms

    Vertical is derived from the roles actually advertised, so a generalist with two nursing ads does not read as a clinical specialist.

  • Volume over headcount

    staffing firms with more than a hundred live postings, any size of office

    The live count is written with the date it was measured, so a stale number is visible instead of quietly assumed current.

  • Multi-office groups

    staffing agencies with offices in at least three states, and show me each branch

    Branches arrive as rows linked to the parent, so a branch manager and a group owner never land in the same sequence.

Plays

Three motions you can run this week

Each one is a chain of Oxygen primitives — the same hosted objects your workspace already has, composed.

  • Volume-banded target list

    Agencies grouped by live requisition count, so pricing conversations start in the right place.

Who you can reach

Roles you can find at staffing and contract labor agencies

Reachability is per channel: a role marked for mobile is one the phone waterfall usually resolves, not a guarantee for every record.

Filters you can search on

  • Verticals inferred from posted roles
  • Live posting volume band
  • Permanent, contract, or temp mix
  • Headcount band
  • Number of office locations
  • State, country, or metro area
  • Applicant tracking system detected

Agencies that advertise on public boards resolve richly: verticals, volume, and often the recruiter named on each ad. Firms working from a private client list look almost invisible by comparison, and executive search boutiques barely post at all. For that slice, rank on headcount and office count instead and expect a shorter list.

Data sources

What the data actually comes from

Every value lands with its provider and cost recorded on the cell.

  • TheirStack

    Live and historic postings, which supply both the vertical mix and the volume band per agency.

  • Op

    Open Web Ninja

    Office listings with address, phone, and site, which is how multi-branch groups expand into rows.

  • People Data Labs

    Company and people records for headcount, founding year, and the staff at each office.

  • Blitz API

    Runs first on the email column and resolves most rows before any metered lane is touched.

  • LeadMagic

    Handles the residual and returns work email or mobile, charged when it finds one.

Run these on Oxygen's managed credits, or connect your own provider keys and pay the vendor directly — the same columns, the same runs, the same provenance either way. See every integration.

Limits

Where this stops

  • Posting counts include reposts and duplicate ads across boards. Treat the number as a band, not a requisition count, and re-measure before quoting it back to anyone.

FAQ

Questions people ask first

Why band agencies by posting volume?
It maps to operational pain better than revenue or headcount. A firm running hundreds of live ads has a coordination problem today, and that is the conversation worth opening.
How do you tell staffing from executive search?
By the roles advertised and the volume behind them. Contract and temp firms advertise constantly; retained search barely advertises at all. Both stay on the list, tagged differently, so each gets its own message.
Can I get a contact at each branch office?
Yes. Branches expand into their own rows linked to the parent, then the contact column runs per row. Suppress the parent domain once so the group is not hit from five directions.
Will I see which applicant tracking system they use?
Where it is visible on the careers site, yes, and it becomes a column. Many agencies run theirs behind a login, so the cell stays empty and counts as unknown rather than a negative match.
Is this list any use for partnerships rather than sales?
Yes. Filter to firms placing the roles you hire for and run a partnership sequence instead of a sales one. The table, the columns, and the enrollment work exactly the same way.
What is free here and what draws credits?
Building the table, writing column definitions, and drafting the sequence are free. Running columns, enrichment, AI steps, and the workflow actions around them draw credits, and every one of them previews its cost first. Connecting a sending mailbox needs a paid plan.
