TheirStack for staffing firms: what it does, where it stops, and alternatives
By Drippay, Inc.Published 8 min read
TheirStack sells job-postings data and technographic data. A staffing firm that sees a feed of new postings reasonably asks whether it is a lead source. Partly. It tells you which employers are posting roles in your niche. It does not tell you who owns the search, whether you have history with the employer, or what happened before the post went up.
Everything about TheirStack below comes from its own pages, checked on October 6, 2026. Disclosure: we build dreach, a managed service for staffing firms that already have employer clients. dreach flags past clients hiring again and employers about to hire, and names the hiring manager. It is not a job-postings database.
while you compare
dreach shows the client ledger.
Your team decides who to contact.
the short version
- Pick TheirStack if you have someone on the team who will build the workflow, and you want postings as data through an app, an API, or webhooks, filtered by title, location, and industry.
- Pick another job-data API if you want a different mix of sources, volume, or price. Coresignal and Fantastic.jobs both sell job-posting data by API.
- Pick Sales Navigator alerts if you work from LinkedIn and care more about people and job changes than about the posting itself.
- Consider dreach if you already have past clients and want a lead that arrives with the hiring manager, the dated evidence, and your warmest way in.
What TheirStack is
TheirStack describes itself as a tool for finding customers through technology usage and hiring signals. It says it analyzes 250M job postings from over 195 countries and tracks 33k technologies. Its hiring-signals page says it monitors 362k sources and can alert you to new and closed postings through webhooks, Zapier, N8N, or Make.
The product is aimed at software and marketing teams that sell to companies using a given technology. In the app you get job search, company search, company lookup by domain, enrichment of an uploaded list, CSV and Excel export, and email alerts on saved searches. An API, webhooks, an MCP server, and bulk datasets sit alongside it.
Where TheirStack fits in staffing business development
Three features line up with a staffing firm’s needs. The filters cover job title, location, seniority, salary, company size, and industry. The home page says alerts can automatically exclude recruiting and consulting firms, and the job dataset carries an is_recruiting_agency flag on the company, so you can screen out other agencies’ postings. And the dataset records when TheirStack discovered a job and when it detected the job closing.
Freshness is stated on its freshness page: it discovers 73% of new postings the same day, 91% by the end of the next day, and 97% within three days. That is quick, but it is still after the employer posted. The closed signal tells you a posting went offline, not that anyone placed the role.
Used well, it gives a researcher a daily list of direct employers posting in your niche. That is a better starting list than a job board, if someone is willing to turn it into calls.
What TheirStack costs, from its own pricing page
TheirStack sells two kinds of credits. Company credits are for the app: revealing or exporting a company uses one credit, and you can view that company and its jobs without limit for 90 days. API credits are for the API and webhooks: a returned job costs one credit, and a company or a technology lookup costs three. Unused paid credits roll over for 12 months, and the page offers a free start.
| Plan type | Smallest listed tier | A larger tier | Unit |
|---|---|---|---|
| App, company credits (one-time) | 1,000 credits for $109 | 10,000 credits for $299 | One company revealed or exported |
| API credits (monthly) | 1,500 credits for $49 a month | 20,000 credits for $240 a month | One job returned; three for a company lookup |
| Datasets | Talk to sales | Talk to sales | Jobs, technographics, or buying intents delivered to your storage |
Where raw postings stop short for a staffing firm
None of this is a flaw in TheirStack. It is a data product for a different buyer. For a staffing firm, five gaps matter.
- A posting is not a person. Its signals page says payloads include hiring manager details, but its data dictionary lists a fill rate of 5.88% for the hiring_team field. For most postings you still have to find who owns the req. We did not see an email or phone field in the job dataset.
- A posting is not a buyer. An employer posting many roles may have an exclusive vendor, need an MSP, or want roles you cannot fill profitably. Targeting every company with open jobs is a common funnel mistake.
- It does not know your history. A client you placed last year looks like any stranger in the feed. Your past clients, the people you placed, and the orders already in progress are not in its data.
- It starts at the posting. Funding rounds and headcount growth are company filters, but the product is organized around the job post. The signs before the post, such as a VMS switch or a hiring leader who moved from a client, are not its focus.
- It leaves the work to you. Someone has to score the feed, find the manager, check the contact, and write the call. At the volume a feed produces, that is a job.
The fix is not a bigger feed. Customers say: “It’s definitely not a volume thing. It’s a timing thing.” A firm that knows which five employers moved this week does better than one with five hundred postings in a spreadsheet.

TheirStack alternatives
The right alternative depends on what is missing. If you want a different postings source, compare the APIs. If you want people and job changes, look at LinkedIn. If you want the lead already assembled, that is a managed service.
| Option | What it gives you | What it leaves to you |
|---|---|---|
| TheirStack | Postings, technographics, closed-job signals, by app, API, or webhook | Finding the manager, the contact details, your history, and the call |
| Coresignal Jobs API | Page cites 482M+ postings, 85+ fields, and active jobs rescraped every 24 hours | The same: it is data, not a lead |
| Fantastic.jobs | Job feeds from career sites and ATSs by API, with hourly refresh and daily expiration checks | The same: it is data, not a lead |
| Sales Navigator alerts | Alerts on signals such as job changes and new content | Posting detail, manager confirmation, and a seat for each user |
| dreach | Past clients hiring again and employers about to hire, with the manager and the warmest way in | Not a database or a feed; your team makes the call |

Where dreach fits
dreach starts from the other end. You give it the clients to watch, with role types, locations, and anything to leave out. It reads roles from each employer’s own careers page and flags when a past client is hiring again, or when an employer like them is about to: a company switching its VMS, a hiring leader who just joined from one of your clients, a private-equity owner spinning off a company, a burst of openings, or a role still open after 30 days.
Each lead comes with the hiring manager, confirmed in the job, with a current email and phone, and the warmest way in through a current or past client, a person your firm placed, or a contact your team authorizes. Your team works each lead from its own accounts.
dreach is priced as a monthly minimum credited against a fee on results, only on orders that started with a dreach lead. If you only want raw postings in a spreadsheet, TheirStack or another API is the better fit.

A fair test on your own clients
Before you buy anything, run this check. Pick 20 employers you have placed with, or know well. For the last 90 days, count how many new roles each tool surfaces from those employers, how many days after posting you see them, and how many come with a named manager you could call. The tool that wins on your clients is the one to keep. This is a method, not a result: we have not run it against TheirStack.
TheirStack is a capable postings and technographics data product, priced openly. For a staffing firm it gives a list of employers posting roles, and the manager, the history, and the timing are still your work. If the employers are already your clients and the gap is knowing when they move, dreach is built for that.
