Top 10 Offshore Staff Augmentation Companies
Every company on this list offers offshore staff augmentation, and they differ sharply in how much of their business it makes up. Clutch shows this directly. Each profile splits a company’s work into service lines with percentages attached, and for the 9 other firms compared here alongside us, staff augmentation runs from a quarter of the mix to an unquantified line next to web, mobile and AI development. For a buyer hiring engineers in India, Vietnam, Bangladesh or Ukraine, that share is a fast first read on how much of a provider’s daily work involves engineers who take direction from a client.
We run staff augmentation and Employer of Record work as our core business, placing engineers through our IT staff augmentation services in any country a client needs, with hubs in Europe and Israel as our base, so our row describes our own model. The other 9 rows come from each company’s Clutch profile and its own website as published in 2026, and where those sources disagree, the text says so. The order of the list carries no ranking. Distance is the second thread running through this list. An engineer in Ho Chi Minh City starts the day 11 hours ahead of New York in summer, and that gap shapes an offshore engagement from the first standup onward.
The other 9 companies come from a longer list of offshore providers we checked. Each one either shows staff augmentation on its Clutch profile or describes a client-directed team model on its own site, and each has its headquarters or its main engineering base in India, Vietnam, Bangladesh or Ukraine. Firms whose public profiles showed no staffing line at all were left out, even when they’re well known for offshore development.
10 offshore staff augmentation providers, by headquarters, offices and staffing share
| Company | Founded | Headquarters | Other offices | Staff augmentation’s share, per Clutch |
| Newxel | 2017 | No single headquarters named; offices in Warsaw, Florida and Tel Aviv | Hiring hubs across Europe and Israel | 60%, with HR outsourcing and IT consulting making up the rest |
| Bestarion | 2018, per Clutch | Ho Chi Minh City, Vietnam | Austin, Texas | 25% |
| Jellyfish Technologies | 2011 | Noida, India | Salt Lake City sales and marketing office | 20% |
| Saigon Technology | 2012 | Ho Chi Minh City, Vietnam | Da Nang, plus branches in Reston (Virginia), Australia, Switzerland and Singapore | 10% |
| Algoscale | 2014 | Noida, India | None listed on Clutch | 10% |
| Riseup Labs | 2010 per Clutch, 2009 per its site | Dhaka, Bangladesh | London, Dubai and New York | 10%, as one of 10 equal service lines |
| TatvaSoft | 2001 | Ahmedabad, India | Murphy and Dallas (Texas), Melbourne, London, Kawasaki and Toronto | Listed, no share given |
| Aalpha Information Systems | 2008 | Bengaluru, India, per Clutch | Hubballi and New Delhi per Clutch, plus Wilmington, Delaware and Sharjah per its site | Listed, no share given |
| Lemberg Solutions | 2007 | Lviv, Ukraine | Hamburg and Krakow | Listed, no share given |
| Zfort Group | 2000 | Kharkiv, Ukraine | None listed on Clutch | Mentioned in reviews, no share given |
The last column comes from the service-line breakdown each company publishes on Clutch. A percentage means the company assigns staff augmentation a share of its work. “Listed, no share given” means the service appears on the profile without a number attached.
Provider profiles
Newxel is the row we can describe from the inside. The client’s own lead sets each placed engineer’s priorities and reviews their work. On our side sit recruiting, HR, payroll, compliance, legal support and equipment, the parts that come with employing someone in another country. Our site puts a new team’s launch at 2 to 4 weeks from the first request, and our Clutch profile carries 10 reviews averaging 4.9. Because the hubs sit in European time zones, the setup lines up most easily with UK and European clients, while US East Coast teams share the morning.
Bestarion’s own site refers to more than 21 years of software development services, and Clutch gives 2018 as its founding year. Its staff augmentation page leaves clients “all the rights to manage the resource directly,” with Bestarion covering “developer retention, administrative support, and infrastructure” plus recruiting and onboarding. Clutch lists 3 reviews, all rated 5.0. Engineer location and working hours are the gap in that page, so confirm both directly.
Jellyfish Technologies leans toward AI projects, with staffing a fifth of its Clutch mix, which suits a buyer who needs machine learning or data experience added to an existing team. Its profile concentrates on services, offices and reviews, so day-to-day management, replacements and working hours are first-call questions. Clutch lists 28 reviews averaging 5.0.
Saigon Technology reports more than 400 software developers in Vietnam and describes a client-led model on its staff augmentation page: the client’s team “sets priorities, tools, and technical decisions throughout,” while an account manager handles commercial questions and stays “out of your delivery decisions.” It employs the engineers and covers HR, payroll, equipment and replacement. It also claims 10 to 12 hours of daily overlap with US teams, which at this distance means shift work, and a buyer can ask to see the schedule. Clutch shows 9 reviews averaging 4.8.
Algoscale describes a team of 80+ data and AI specialists on its own site, and its dedicated team model is “a full-stack AI and data team embedded in your operations,” sold alongside project-based and advisory work. That fits a buyer who needs data engineers or ML specialists folded into an existing product team. Day-to-day management of those specialists, and the hours they keep, belong in the scoping conversation. Clutch lists 12 reviews averaging 4.9.
Riseup Labs advertises the ability to “hire a team in 7 days” with “dedicated developers, engineers, QA, and IT experts,” though management and employment details are left for scoping. Dhaka runs 10 hours ahead of New York in summer, so overlap with a US team needs deliberate planning. Clutch lists 45 reviews averaging 4.9.
TatvaSoft is the largest company here, at 1,000 to 9,999 employees on Clutch, and custom software development makes up half of its Clutch mix. Its dedicated development team page gives clients “complete control” over hired resources and daily progress in Jira, Trello, Slack and Microsoft Teams, while a TatvaSoft project manager “oversees the entire project lifecycle” and the company replaces a developer if problems come up. Client control plus a vendor-side project manager is a setup to map out before signing. Clutch lists 48 reviews averaging 4.9.
Aalpha Information Systems reports 250+ developers on its site, Clutch lists it at 50 to 249 employees, and web development leads its Clutch mix at 45 percent. Its hire-dedicated-developers page says developers “integrate with your team” and work in the client’s Slack, Jira, Trello, GitHub and Zoom, with Aalpha handling screening, onboarding, developer performance monitoring and code reviews. With performance monitoring on the vendor’s side, agree early how that sits next to the client’s own management. Clutch shows 218 reviews averaging 4.9.
IoT development makes up half of Lemberg Solutions’ Clutch mix, which matches its site’s focus on embedded engineering and an offering it calls embedded staff augmentation. Its team extension page has the client define the skill set, stack, backlog and timeline, with setup taking about 3 to 4 weeks, and Lemberg handling recruitment, screening, interviews, onboarding and facilities. It says teams keep a 3 to 4 hour overlap with US time zones. Clutch lists 27 reviews averaging 4.8.
Zfort Group is the oldest company here and reports 18+ active dedicated teams on its own site. Its dedicated team page is clear about control: “product priorities, roadmap, and daily involvement remain under client control,” while Zfort handles recruitment, onboarding, infrastructure, retention, contracts, payroll, equipment and replacement. Clutch lists 23 reviews averaging 5.0. For a US client, Kharkiv runs 7 hours ahead of New York, so the working day overlaps in the US morning.
How these providers describe control over the engineer
Clutch’s service mix shows how much staffing a firm does. The providers’ own service pages show how they run it, and on that question the companies here sort into a few clear patterns.
Bestarion, Saigon Technology and Zfort put client control in plain words on their service pages, as quoted in the profiles above, and each also spells out the employment-side work it carries, from retention and infrastructure to payroll, equipment and replacement. For a buyer, those public descriptions are a useful reference when the contract gets drafted.
TatvaSoft and Aalpha pair client control with oversight on the vendor’s side: a project manager in TatvaSoft’s case, performance monitoring and code reviews in Aalpha’s. Some clients want that extra layer. It does mean the buyer and the provider need to agree, in writing, whose word counts when priorities conflict.
Lemberg and Algoscale describe the setup more than the daily reporting line. Lemberg’s team extension page walks through defining the team, stack, backlog and timeline, followed by a 3 to 4 week setup, and Algoscale describes its dedicated team as embedded in the client’s operations. Both leave the question of day-to-day management for the conversation.
For Jellyfish and Riseup Labs, the public pages checked for this list focus on services, offices and hiring speed, so engagement mechanics are a topic for the first call. Many firms keep contract detail for sales conversations.
Whatever pattern a provider follows, 3 lines in the contract settle most of it: who assigns the engineer’s tasks, who runs performance reviews, and who decides on a replacement. Some providers here already answer those publicly. For the rest, those lines are the ones to ask for before a proposal turns into a contract. If the answers on a call differ from what the provider’s own service page says, raise it before signing, since the page is what the buyer’s team will have read and will expect.
Team shape changes the picture too. A single engineer added to an existing squad needs the client’s lead and a few shared hours. A group of engineers working as one unit on its own roadmap is closer to fullstack dedicated development team services, and at offshore distances that unit needs its own lead in a compatible time zone, so handoffs happen inside the team instead of across a 10-hour gap.
What the staffing share on Clutch tells a buyer
Of the 9 other providers compared here, 5 publish a staffing share on Clutch, 3 list the service without a number, and 1 mentions it only through client reviews. The share is self-reported. Each company sets its own service-line split on Clutch, so the number reflects how a firm describes its business, and it can lag behind a change in what the firm sells today. It still separates 2 kinds of provider. A firm with a quarter of its work in staff augmentation sells that arrangement often, so its contracts should already cover replacement terms and HR support for people it doesn’t manage day to day, and that’s easy to confirm on a first call. A firm where staffing is an unquantified line next to project work can run augmentation well, but a request may end up routed through the project structure it uses most unless the buyer asks for the staffing setup by name.
Distance is the other half of the picture. Measured against New York in summer, Kharkiv and Lviv run 7 hours ahead, India 9.5, Bangladesh 10 and Vietnam 11. India, Bangladesh and Vietnam don’t change their clocks, so each of those gaps grows by an hour when the US moves back to standard time. A UK client sees a gentler gap: India is 4.5 hours ahead of London in summer and Vietnam 6, which leaves most of the Indian working day shared. That’s why offshore staff augmentation in Asia fits UK and European teams more easily, while US teams tend to build around a short shared window or an agreed shift.
West Coast teams face the widest gaps. Measured against San Francisco in summer, India runs 12.5 hours ahead and Vietnam 14, so the only shared time is the US evening, which is already the next morning in Asia. Teams in that position often work as a relay: the US side reviews and unblocks at the end of its day, the offshore side builds through its own day, and a short written handoff carries the context across. Ukraine sits much closer to the UK, only 2 hours ahead of London, so for a UK client a team in Lviv or Kharkiv works almost the same day.
Some offshore providers also sell offshore development center services, and moving from a few augmented engineers to a center with its own office, equipment and local management is a different purchase, with its own legal setup in the host country and a longer commitment on both sides.
Data, access and the law in the engineer’s country
An offshore engineer needs access to the client’s code, and often to production data or customer records as well. Where that data may go is first a legal question. A UK or EU company that lets an engineer in India, Vietnam or Bangladesh work with personal data is transferring that data out of the UK or EU under data protection law, and that calls for a recognized transfer mechanism, usually standard contractual clauses or the UK’s own version of them. A provider that regularly places engineers with European clients should have that paperwork ready and know who signs it on each side.
US clients deal with rules that depend on the sector. Health data under HIPAA and card data under PCI DSS carry obligations that follow the data to whoever handles it, including an engineer employed on another continent, so the provider has to show how its engineers’ access fits the agreements the client already has in place.
The simplest protection is to keep the data where it already lives. Engineers sign in to the client’s systems through the client’s own identity provider, build and test against anonymized or synthetic data, and reach production only through logged, time-limited access. Set up that way, the engineer’s country matters less, and offboarding means closing an account instead of recovering files from a laptop.
Local law shapes the employment side too. Notice periods, mandatory benefits and the rules for ending a contract differ between India, Vietnam, Bangladesh and Ukraine, and the provider carries them as the employer. A buyer doesn’t need to learn each system, but should ask how long it takes under local rules to release or replace an engineer, since that timeline decides how fast a team can shrink when a project ends.
Checking written communication before the offer
Across a 7 to 11 hour gap, most of the work is written. Tickets, pull request comments and short updates carry what a hallway conversation would carry in an office, so the ability to write a clear paragraph matters as much as the stack on a CV. A 30 minute call tells a buyer very little about that, because a call rewards fluency in speech, not precision in writing.
2 checks take almost no time. Ask the candidate to review a real pull request and leave comments, or to write a short plan for a task from the backlog, and read what comes back the way a teammate would. Ask the provider how it assesses written English rather than spoken English, since many screening processes test only the second. Providers that place engineers with UK and US teams regularly usually have an answer ready, and the ones that don’t tend to say the interview covers it.
The same check applies to the client side. A team that writes tickets as one-line reminders for itself will have to write them properly once an engineer 10 hours away depends on them, and that shift takes a few weeks to settle. Starting it before the engineer arrives turns the first sprint into work instead of a negotiation about how much detail a ticket needs.
A provider that sends a writing sample instead of a reassurance will usually be as concrete about the harder questions later on.
Holiday calendars and leave in offshore countries
Every country on this list runs its own calendar, and the differences are bigger than a US or European team expects. Tet closes offices in Vietnam for the best part of a week, and the days around it are quiet on both sides of the holiday. India’s public holidays vary by state, so 2 engineers at the same provider can be off on different days. Bangladesh and Ukraine each have their own set again.
None of that is a problem when it’s on the calendar before a sprint is planned. It becomes one when a release date lands in the middle of a national holiday nobody on the client side had heard of. Ask each provider for the holiday list for the engineer’s country and location, and ask how leave is approved: some providers manage it centrally, others leave it to the engineer to agree with the client. Then agree who covers what during those days: a week of Tet with nobody on call is fine for a team shipping every 2 weeks, and expensive for one running a service with paying users at night.
Common mistakes when hiring offshore engineers across a big time gap
One is reading the staffing share as a promise about a specific engagement. The number describes a company’s overall mix, and the engagement in front of a buyer depends on the proposal, the account team and the engineers assigned to it.
Another is assuming overlap will sort itself out. When a provider in Asia advertises long daily overlap with US teams, that overlap comes from shift patterns, so a buyer should know which engineers work which hours and whether late shifts are permanent or rotating.
A third is letting a vendor-side project manager become the main channel by default. Some dedicated team models include one, which suits some clients. For a buyer who wants engineers inside their own team, it helps to decide in the proposal whether that role exists at all.
A fourth is leaving all the interviews to the provider. Offshore hiring works better when the client’s own lead meets finalists live, even if that means an early or late call, since the lead is the person who’ll work with the engineer every day.
Planning only for the East Coast is a related one. A company whose engineering leads sit in California faces a 12.5 to 14 hour gap with India and Vietnam, and the only shared hours fall in the US evening.
Skipping a written handoff routine causes quieter damage. Across a 10-hour gap, a short end-of-day note on what’s done, what’s blocked and what’s next can save a day each time a question would otherwise wait for the next overlap.
The last is judging communication by the sales team. The account manager a buyer meets in the first calls usually isn’t the engineer who’ll join standups, so a short working session with the actual candidate says more about daily communication than any pitch.
Frequently asked questions about offshore staff augmentation
What’s the difference between offshore and nearshore staff augmentation?
Mostly distance and time zones. Nearshore usually means a neighboring region with a similar workday, such as Latin America for US companies or Central Europe for Western European ones. Offshore covers bigger gaps, like India, Vietnam or Bangladesh for US clients, where the shared part of the day is short or planned through shifts.
Can an offshore team in Asia work US hours?
Some providers arrange it through evening or night shifts, and a few advertise long daily overlap with US teams. Ask which engineers work shifted hours, whether the arrangement is permanent, and how the provider supports engineers who keep those hours over months.
Is offshore staff augmentation easier for UK and European companies?
Usually, because the gap is smaller. India is 4.5 hours ahead of London in summer and Vietnam 6, so most of the working day is shared, while US East Coast teams face gaps of 9.5 to 11 hours with the same countries.
Does a high Clutch review count mean more staff augmentation experience?
No. Reviews cover every service a company sells, and on this list the 2 largest review counts belong to firms whose Clutch mix is led by web or custom development. The staffing share, and individual reviews that describe staffing engagements, say more about augmentation experience.
How can a buyer check staff augmentation experience beyond Clutch?
Ask for references from staffing engagements specifically, separate from project work, and ask how many of the provider’s engineers currently work inside client teams compared with its own projects. The answers show how much of the bench is used to reporting to someone outside the company.
What kinds of roles work well across a large time gap?
Work with clear specs and review points travels best: backend services, data pipelines, QA automation and maintenance of existing systems. Roles that depend on constant back-and-forth with product or design, or on being on call during US business hours, need more shared time or a shift arrangement.
What does “listed, no share given” mean in the table?
The company shows staff augmentation as a service on its Clutch profile but doesn’t assign it a percentage of its work. The service exists; how often the company delivers it is a question for the first call.
Who employs an offshore engineer placed through these firms?
Where the providers spell it out, as Saigon Technology and Zfort do on their service pages, the provider carries the employment side, including contracts, payroll and HR, while the client directs the work. Details such as equipment, replacement and who covers onboarding time differ by provider and belong in the contract.
