Why choose SumatoSoft for IT staff augmentation
Senior, vetted talent
70% of our engineers are senior-level. Every candidate passes technical screening, a practical task, an English check, and a culture-fit interview before we put a CV in front of you.
Fast start
You receive matching CVs within 1 business day. Interviews run as soon as the shortlist reaches you, and onboarding starts once the contract and NDA are signed. Traditional hiring for the same role runs for months.
An employed team rather than a gig marketplace
Our specialists are SumatoSoft employees on permanent contracts. That is what stands behind our 70% repeat-Client rate. When someone leaves your project, replacing them is our job and our cost.
EU nearshore from Warsaw
Our development center is in Warsaw. You get several hours of daily overlap with US East Coast working hours, plus GDPR-aligned data handling inside the EU. Senior engineers cost well below the equivalent US in-house hire.
Flexible terms
Start with one specialist and scale to a cross-functional team, then scale back after release. The minimum engagement is one calendar month. We do not require a twelve-month commitment.
A fixed, transparent rate
We agree on an hourly or monthly rate per specialist before work starts, and it does not move. No hidden fees, no unbilled coordination overhead. An NDA is standard, and we hold ISO 27001 certification.
Our vetting process
Every specialist you receive a CV for has already passed four stages.
After joining, our engineers continue through internal training and certification. You interview every candidate before they join and make the final call.
We recruit for permanent employment rather than per project, so we assess candidates against a long-term bar.
A live technical interview with one of our engineers, plus a practical task in the candidate’s primary stack.
Candidates speak with an assessor before they reach any Client-facing shortlist. We staff Clients who work in English.
We check how well the person works inside someone else’s team, because that is what augmentation asks of them.
Estimate your project cost here
Challenges you can solve with IT staff augmentation
Staff augmentation addresses shortages of people and gaps in specific expertise, and it covers the wait for permanent hires.
Resource or skill shortages
You lack the developers for a new project, or nobody in-house knows the technology it needs. Staff augmentation quickly fills in the gaps.
Scarce AI and ML skills
Your local market cannot supply AI or ML engineers fast or affordably.
Tight deadlines and workload peaks
A release slips or the backlog doubles. Extra specialists absorb the peak without permanent headcount.
Temporary projects
When you need a skill for one project, engaging a specialist costs less than hiring, onboarding, and later redeploying a permanent employee who no longer has that work.
Waiting on permanent hires
Recruitment is running, and the work cannot wait. External specialists cover the gap and hand over cleanly when your hire starts.
Business benefits of IT staff augmentation with SumatoSoft
Rapid team expansion
Expand your development team in days or weeks. Permanent hiring for the same roles takes months of sourcing and notice periods.
Cost control
You pay for hours worked. No benefits, vacation accrual, equipment, recruitment fees, or bench time between projects.
Access to rare expertise
Bring in specialists your market doesn’t supply: AI and ML engineers, IoT developers, predictive maintenance specialists.
Flexibility and scalability
Decide how many specialists and for how long. Scale up for a release, scale down afterward, with no severance and no idle capacity.
Control and integration
Augmented specialists work under your management, inside your processes, on your board. You set priorities and review the work.
Focus on core work
Your permanent staff stay on the work only they can do, while external specialists take the remaining tasks.

Engagement models for staff augmentation
Short-term expansion
Long-term expansion
Flexible scalability
How you’re billed
Short-term expansion
One month or longer, for an urgent release or a temporary workload peak. Specialists join quickly and hand the work back when the engagement ends.
Long-term expansion
Six months or longer, for products under continuous development. The same people stay on your product, so context stays in the team rather than in documentation.
Flexible scalability
Start with one or two developers, grow to five or seven through active development, then reduce after release. We adjust to your schedule and budget.
How you’re billed
Augmentation runs on a Time & Material basis: a rate per specialist, agreed in the contract before work begins, invoiced monthly against tracked hours. One calendar month is the minimum. Comparing this against our project-delivery options? See our engagement models, where Fixed Price, Time & Material, T&M with a budget cap, and Dedicated Team are set out side by side.
How staff augmentation works with us
Describe the skills you need, the seniority level, the start date, and how long the work runs. Send your role description if you have one. If you don’t, we help you define the role.
We send a shortlist from our bench and active pipeline, with real project history for each candidate.
You interview every candidate and choose who joins. Rejecting the whole shortlist is a normal outcome. We’ll send another.
We agree on the rate, start date, notice period, and replacement terms in writing before anyone starts.
We help your new specialists into your environment, your tools, your codebase, and your project context. They follow your schedule and join your ceremonies from day one.
Staff augmentation vs. the alternatives
Each model solves a different problem: a freelance marketplace works well for one fast placement on a bounded task; a managed service works when you want to hand over a whole function against an SLA.
Staff augmentation is a good fit when you need cohesive, retained specialists working within your team, under your management, for months rather than weeks. Permanent hiring remains the right answer for the roles that carry your product’s core knowledge.

How to choose an IT staff augmentation company
Relevant expertise in your industry
Staff augmentation should give you specialists with domain experience. A small vendor claiming deep expertise across every industry with ten in-house experts is overstating what they have. Look elsewhere.
Well-established processes
You can read process maturity from the first contact: how the intro call runs, whether the account manager holds to dates, and how smoothly the contract and NDA move. These early signals tell you what working with the delivery team will feel like.
NDA and data privacy
An NDA and documented data handling are standard for any augmentation engagement. Treat a vendor who calls either one optional as a serious risk to your code and your Client data.
Wide talent pool
A serious vendor has either a strong in-house team or a proven hiring process for building project teams. Either way, ask where the talent comes from and how skills and culture fit get assessed. A vendor who cannot describe their sourcing in specifics is describing a pool they don’t control.
Working hours overlap
Your time zones will differ. The vendor should commit to enough daily overlap for calls, code reviews, escalations, and quick decisions, and put those hours in the contract.
Evidence of AI governance
If you’re hiring AI or ML specialists, ask how the vendor evaluates model output and what they monitor in production. A vendor who can describe their evaluation practice in detail has run AI systems in production. Ours is documented in the Agentic Software Development Lifecycle (ADLC).
Case studies
AI integration of anti-fraud and underwriting for a fintech firm

Toyota custom ERP/CRM system
The system has produced a significant competitive advantage in the industry thanks to SumatoSoft’s well-thought opinions. They shouldered the burden of constantly updating a project management tool with a high level of detail and were committed to producing the best possible solution.
Nectarin LLC aimed to develop a complex Ruby on Rails-based platform, which would be closely integrated with such systems as Google AdWords, Yandex Direct and Google Analytics.
I was impressed by SumatoSoft’s prices, especially for the project I wanted to do and in comparison to the quotes I received from a lot of other companies.
Also, their communication skills were great; it never felt like a long-distance project. It felt like SumatoSoft was working next door because their project manager was always keeping me updated. Initially.
We tried another company that one of our partners had used but they didn’t work out. I feel that SumatoSoft does a better investigation of what we’re asking for. They tell us how they plan to do a task and ask if that works for us. We chose them because their method worked with us.
SumatoSoft is the firm to work with if you want to keep up to high standards. The professional workflows they stick to result in exceptional quality.
Important, they help you think with the business logic of your application and they don’t blindly follow what you are saying. Which is super important. Overall, great skills, good communication, and happy with the results so far.
Together with the team, we have turned the MVP version of the service into a modern full-featured platform for online marketers. We are very satisfied with the work the SumatoSoft team has performed, and we would like to highlight the high level of technical expertise, coherence and efficiency of communication and flexibility in work.
We can confidently say that SumatoSoft has put all our ideas into practice.
We are absolutely convinced that cooperation between companies is only successful when based on effective teamwork (and Captain Obvious is on our side!). But the teams may vary on the degree of their cohesion.
They are very sharp and have a high-quality team. I expect quality from people, and they have the kind of team I can work with. They were upfront about everything that needed to be done.
I appreciated that the cost of the project turned out to be smaller than what we expected because they made some very good suggestions. They are very pleasant to work with.
Rivalfox had the pleasure to work with SumatoSoft in building out core portions of our product, and the results really couldn’t have been better.
SumatoSoft provided us with engineering expertise, enthusiasm and great people that were focused on creating quality features quickly.
We’d like to thank SumatoSoft for the exceptional technical services provided for our business. It should be noted that we started our project’s development with another team, but the communication and the development process in general were not transparent and on schedule. It resulted in a low-quality final product.
SumatoSoft succeeded in building a more manageable solution that is much easier to maintain. Their project management reflects the excellence of a larger company. Their team delivers high-quality results, attentive service, and reasonable pricing.
When looking for a strategic IT-partner for the development of a corporate ERP solution, we chose SumatoSoft. The company proved itself a reliable provider of IT services.
Thanks to SumatoSoft’s can-do attitude, amazing work ethic, and willingness to tackle clients’ problems as their own, they’ve become an integral part of our team. We’ve been truly impressed with their professionalism and performance and continue to work with the team on developing new applications.
We are completely satisfied with the results of our cooperation and will be happy to recommend SumatoSoft as a reliable and competent partner for development of web-based solutions

Frequently asked questions
What AI roles can you provide through staff augmentation?
We supply AI engineers, applied AI engineers, ML engineers, data engineers, data scientists, MLOps engineers, LLM and GenAI specialists, and AI evaluation and safety specialists. You can hire one role or a matched pod covering model development, data infrastructure, deployment, and evaluation.
How much does staff augmentation cost?
Your rate depends on the role, the seniority you need, the engagement length, and the scope of the work. Describe your requirements, and you’ll have a written estimate within 1 business day. There are no fees beyond the agreed rate per specialist.
Who owns the IP and code produced by augmented staff?
You do. All work is produced on a work-for-hire basis, and rights in the code and documentation transfer to you on payment. The terms are set out in the contract, alongside an NDA covering everything your specialists see.
What are the risks of staff augmentation, and how do you handle them?
Managing an expanded team needs an experienced manager on your side. Unclear tasks and thin processes cause people to lose focus. Poor vendor selection creates communication and culture problems. Working without an NDA and access controls risks your data and code. A good provider reduces the first three through vetting, onboarding, active account management, and replacement. The fourth is eliminated contractually.
