Startups Software Development Review from Hector Castillo
We engaged with aTeam with the goals of designing and building a web app for out customers to monitor and control their IoT devices as well as an admin panel for our team to manage users and devices.
I was most impressed by the fact that aTeam did some initial work and wireframing during initial discussions which gave us confidence that aTeam has a solid understanding of our goals and vision before hiring them.
I think the main area of improvement is how QA and testing was done and the impact on our timeline. aTeam was good about delivering milestone deliverables on schedule, but there were often issues that would arise in our own testing that were not caught earlier in their testing, which would create additional work. I think impacts to our timeline could have been minimized if their testing had been more thorough and tailored to the user experience, and if expectations were made clearer at the beginning that, after the final milestone was delivered, there would still be an additional debugging period. Otherwise, aTeam was very good about sticking with issues until resolved.
Overall, I would be very happy and willing to work with aTeam again in the future and to refer them to others.

Mobile App Development Review from Anonymous
It’s been pretty cool using this app for handling all our company’s accounting stuff. You just snap pics or upload your receipts and docs right from your phone, which saves a ton of hassle. On the other side, the accounting team can grab everything they need from the web dashboard, so no more chasing papers or emails back and forth. It’s made tax time way less stressful, especially since it’s tailored for the UAE rules and all that. Plus, the folks behind it don’t just drop the app and disappear, they actually keep checking in, throwing out ideas, and sometimes pushing us to think differently. Communication’s been smooth, and they’re not just doing what you ask but really getting into the project. Definitely a game-changer for us.

Web Development Review from Anonymous
We needed a fresh website that actually worked for us, something that could pull in new folks and keep our regulars in the loop without feeling like a hassle. These guys nailed it. The site looks great and runs super smooth, which honestly makes a big difference. Plus, they helped set up a way to grab emails from visitors, so we’re actually turning clicks into real leads now. They’re pretty chill to work with, always open to ideas and explaining stuff without the techy mumbo jumbo. Definitely made the whole process way less stressful than I expected.

UI/UX Design Review from Yuriy Husev
We hired DreamX to redesign our company website to better reflect DMTs modern approach to B2B lead generation and appointment-setting services. The DreamX team quickly understood our brands personality and transformed it into a sleek, fast, and conversion-focused digital experience. Their UX/UI team created user flows that made our content easier to navigate and optimized for lead capture. Communication was professional and consistent we always knew exactly what stage the project was in. The final result exceeded expectations: the new website not only strengthened our online presence but also positively impacted inbound lead quality. We highly recommend DreamX to any business looking for a creative and reliable design partner.

We worked with DreamX on developing a corporate website, and the results exceeded our expectations.
Their team demonstrated a perfect balance of creativity, technical expertise, and attention to detail.
From the very first step, they carefully analyzed our needs, created a modern and functional design, and ensured a smooth user experience.
What impressed us most was their ability to translate our brand identity into a digital format that feels both professional and engaging.
DreamXs communication was clear and proactive throughout the project, which made the entire collaboration smooth and efficient.

We couldn't be more pleased with our experience with TouchZen. They took over a bad situation left behind by our previous development team and have been able to continue to build new features while cleaning up the old project. We have been very pleased with their developers responsiveness as well as the project management. I would highly recommend working with them for any of your web or mobile app development needs.

B2C Apps Review from Brett Lassig
We have been extremely impressed with TouchZen's development team behind the Get Cover Mobile App. Their approach has been collaborative, and responsive to the needs of our warranty and claims environment.
The app is intuitive for end users while still delivering the robust functionality needed on the backend, especially around claims processing, and real-time updates.
Their diligence has made a significant impact. Features like streamlined claim submission, status tracking, have enhanced both customer satisfaction and operational efficiency.
Overall, this highly capable and professional development team has delivered quality work and stands behind it. We look forward to continuing to build and scale with them.

Mobile App Development Review from Dr Asa Frey
They worked on our app and continue to work on it to this day. We originally had a bad experience with various developers and ended up with a bunch of code and no functioning app - touchzen took the code and audited it and made it work and it work great now. Can't complain - still going to work with them and I would recommend to anyone who wants it done right.

Software Development Review from Kerry Cooper
We partnered with Softellar to modernize our patient records management system and improve overall healthcare delivery, and the results have been outstanding. The project was essential for us, especially during the pandemic, when remote care became a necessity. Softellar's team developed a comprehensive healthcare solution that seamlessly integrated a central patient records management system, telemedicine capabilities, remote health monitoring features, and full regulatory compliance.
Their deep understanding of our unique needs and workflows allowed them to customize the solution effectively, creating a user-friendly system that reduced delays and significantly improved patient care. The telemedicine functionality ensured uninterrupted care during the pandemic, while remote health monitoring provided us with valuable insights into patient conditions, enabling proactive interventions.
What impressed us most was Softellars flexibility and responsiveness. They delivered the project on time, made adjustments when needed, and ensured the system worked perfectly with our existing infrastructure. Their attention to detail and commitment to user experience made the system easy to adopt with minimal training for our staff.

Their engineers were not only highly skilled but proactive problem solvers, helping us tackle challenges in real-time data tracking and loan portfolio performance.

One standout project involved enhancing our platforms user experience for credit unions, banks, and lenders. Softellar's team went beyond mere implementation by offering valuable feedback on design and usability, significantly improving client engagement and satisfaction. They also provided comprehensive post-project support and knowledge transfer, empowering our team to manage and scale independently.

My experience at AgileSoft System, Inc. has been excellent. The management had been too supportive of every requirement for learning. Weekly meetings, fun activities, and brainstorming on new technology/projects make the workplace impressive and allow growth. Even your workmates are always ready to assist you in every doubt and make sure you follow the right path. Overall, the company is an incredible journey and a great learning place.

Agile Soft Solutions is a very good company to work in while enjoying it at the same time. The work culture is very amazing. Management is very supportive whenever there is some kind of support required. The company also encourages and recognizes the effort of every associate.

I have worked with AgileSoft Systems, Inc. for the last 2.1 years. I started my professional career with the company as a Fresher. The experienced seniors of the company provide excellent training and learning to Freshers. I got the opportunity to work with international clients that really upskilled my talent. Here are some of my personal experiences with them:
- On-time Salary and didn't lay off any employee during the pandemic.
- They provide complete flexibility to employees including break timings and shift timings
- World-class Infrastructure and facilities.
- Organize outings
- Supportive co-workers

What services does a software testing company provide for your business in the United States?
They provide a comprehensive range of services designed to validate and improve software quality through systematic evaluation and advanced tooling.
Core testing services include:
Quality assurance and testing strategy: Audits software and defines testing scope, priorities, coverage, approach, and reporting.
Functional testing: Verifies that software features work according to specified business and functional requirements.
Regression testing: Detects unintended issues introduced by system changes and releases.
Performance and load testing: Measures the application’s reliability and responsiveness during peak usage.
Security testing: Identifies and resolves security vulnerabilities and tests against compliance and governance requirements.
Usability testing: Assesses user experience, interface intuitiveness, and overall accessibility of the solution.
Integration and API testing: Validates how different system components and third-party services work together.
In addition to these services, software testing companies implement a mix of manual (often for exploratory and user experience-focused scenarios) and automated (repeatable checks throughout the development cycle for speed and consistency) testing models.
How much does software testing cost?
Software testing costs about 15%-25% of the development costs or 23% of the IT budget. In terms of hourly rates, US software testing companies charge an average of $100-$250 per hour, with more complex systems or specialized tests going beyond $300/hour.
The final rate will depend on solution complexity, testing coverage, quality requirements, project timeline, and current technical debt.
Here’s how much software testing costs as a percentage of the software development budget:
Critical systems and highly regulated industries: 40%-50%
Enterprise applications: 25%-35%
Consumer-facing applications: 15%-25%
Mobile applications: 20%-30%
In practice, basic one-time testing projects, such as a website penetration test, cost approximately $5,000-$10,000.
On the other hand, continuously evolving software solutions that require regular comprehensive testing can fetch between $20,000 and $70,000+ per month.
Are there any additional costs to consider when working with US software testing agencies?
Beyond project scope, complexity, and timeline, these are additional costs to consider when working with software testing agencies in the USA:
Tooling and platform fees: Software license or subscription fees for device farms, performance testing platforms, and security scanning tools may be billed separately from the company’s overall rates.
Device/browser lab coverage: For tests that require broad compatibility coverage, costs can increase based on access to real devices, operating system versions, and browsers.
Scope growth: New testing requirements, additional integrations, new platforms (mobile/web), or expanding acceptance criteria often require a change order.
Additional test cycles: Extra rounds of re-testing and regression tests beyond what’s defined in the service level agreement (SLA) incur additional costs.
Defect remediation effort: Fixing defects is often outside the testing scope and is billed as an additional engineering or development fee.
Compliance and security deliverables: If you require additional formal evidence (e.g., audit artefacts and traceability) or expanded security testing, expect incremental charges.
How long does software testing usually take?
On average, software testing takes around 20%-40% of the total software development time. However, the final timeline will depend on infrastructure complexity, test scope and methodology, and quality requirements.
Here’s an approximate software testing timeframe based on the typical software project schedules:
Full Release Schedule
Software Testing Timeframe
Small software builds (e.g., Landing platforms)
12-24 weeks
2-4 weeks
Mid-sized builds (e.g., Fully customized mobile apps)
16-40 weeks
3-4 months
Large builds (e.g., Multi-module platforms)
36-144 weeks
6-12 months
Notably, software testing is often integrated into the software development lifecycle (SDLC). As such, it’s common to see QA and testing done in 1-2-week sprints rather than a separate stage altogether.
What industries do US software testing firms typically work with?
US software testing providers work with a wide range of industries, as all digital solutions need to be tested in some capacity. However, these are the sectors that quality assurance (QA) and testing experts work in based on the State of Testing Report 2025:
Tech: 35.2%
Finance and insurance: 16.9%
Others: 12.7%
Healthcare: 10.9%
Business and information: 4.5%
Retail: 4.1%
Marketing: 3.7%
Transportation: 3%
Government: 3%
Gaming: 2.6%
Education: 1.9%
