Most “top IT staff augmentation companies” pages are written by one of the companies on the list, which then appears at number one. We publish this one and we are on it, so treat that as a declared interest rather than a hidden one. What follows is a comparison built on facts each firm publishes about itself, with the gaps marked rather than filled.
Every fact is quoted from a page the company itself controls. Clutch, Wikipedia, Crunchbase and press coverage were deliberately not used.
Where a firm publishes no figure, the cell reads “not published” rather than an estimate.

How this comparison was built
Every fact in the table comes from the company’s own website, quoted from a page they control. Clutch profiles, Wikipedia, Crunchbase and press coverage were deliberately not used as sources of truth, because they are frequently stale and none of these firms controls what they say. Where a company does not publish a figure, the cell reads “not published” instead of an estimate.
Two consequences worth stating. First, some cells are empty that you would expect to be full: several large staffing firms publish revenue or recruiter counts but never an engineer headcount, and those are different quantities that should not sit in the same column. Second, one firm is missing entirely, explained below.
The comparison
| Firm | Headquarters | Self-reported size | Where delivery happens |
|---|---|---|---|
| Sthenos Technologies | Tysons, Virginia, with an office in North Bethesda, Maryland | Not published as a headcount | US, with a NeoSoft Tech partnership for additional engineering capacity |
| ScienceSoft | McKinney, Texas | “A team of 750+ architects of IT success” | Not stated. US HQ plus “representative offices in the UAE, KSA, Europe, and Mexico”; where engineers sit is not published |
| BairesDev | California (state only; they do not name a city) | “Our 4,000+ software engineers span over 20 countries across Latin America” | Nearshore Latin America, per that same statement |
| TEKsystems | Hanover, Maryland | Not published as a headcount. They state “100+ Locations worldwide” and “$7B+ Annual revenue” | “dedicated national recruiting centers across the U.S.” |
| Insight Global | Atlanta, Georgia | Not published as a headcount. They state “2,000+ recruiters” | “5 global delivery centers in the US, India, and LATAM” |
| Everforth Apex (formerly Apex Systems) | Glen Allen, Virginia | Not published | Not clearly stated as a delivery model |
| Andersen | Warsaw, Poland | “3,500+ in-house experts” | Development centres listed in Munich and Krakow; London is a representative office |
| Revelo | Miami, Florida | “over 250 remote employees” (this is Revelo’s own staff, not the size of its talent pool) | “distributed across United States and Latin America” |
Three things the table will not tell you
“Headquartered in the US” and “delivered from the US” are different claims
Several firms on this list hold a US headquarters while delivering from elsewhere, which is a legitimate model and often the cheaper one. It matters when your contract, your data residency rules or your security review assume otherwise. Ask where the engineers who will touch your systems actually sit, and get it in the statement of work rather than in a sales call.
Size figures are not comparable across firms
An engineer headcount, a recruiter headcount and an annual revenue figure answer different questions. A firm with 2,000 recruiters is telling you about its sourcing capacity, not about the bench. Compare like with like or not at all, which is why several cells here are deliberately blank.
The model matters more than the vendor
Staff augmentation, a dedicated team and project outsourcing fail in different ways, and choosing the wrong one is a more expensive mistake than choosing the wrong firm within the right one. Our comparison of staff augmentation, managed services and outsourcing covers where each breaks down.
Who is missing, and why
Toptal is absent. Their site returns an HTTP 403 to automated requests, so nothing about them could be verified from a page they control, and we would rather leave a known name off the list than publish facts we could not check. That is a limitation of this comparison, not a comment on the firm.
One name has also changed: Apex Systems now trades as Everforth Apex, and states on its own site that it “is part of the Commercial Segment of Everforth, Inc.” Comparison pages that still list it as Apex Systems have not been updated.
What to ask any firm on this list
- Where will the engineers physically be? Get the country in writing, not the head office.
- Who owns the code, the repository and the deployment credentials? Settle this before work starts, not at the end.
- What is the replacement obligation? Notice period, replacement window, and what happens to knowledge transfer during a swap.
- Who directs the work day to day? If the answer is “you do”, that is augmentation, and it only works if you have the management capacity to do it.
- What happens at the end? Handover, documentation and credential return should be defined at the start.
If you want to talk through which model fits your situation rather than which vendor, talk to our engineers. If you already know you need people rather than a project, our IT staff augmentation service explains how we run it.
