Kevych Solutions Reviews & Testimonials
Vasco Rouw Founder at Mavelli
5.0★
Mobile App Development Review from Vasco Rouw
Weve been working with Kevych Solutions full-time for over a year, and the experience has been excellent. They handle the complete end-to-end development of our AI-powered mobile apps, including UI/UX, frontend and backend development, AI integrations, infrastructure, deployment, and ongoing support.What stands out most is the extremely high level of their technical expertise and execution quality. They actively use AI and modern development workflows to maximize efficiency and deliver results quickly. The team is highly responsive, proactive, and always goes the extra mile to meet deadlines.Since working together, we scaled from 0 to over 100,000 subscribers in just 8 months, and our apps are now generating more than $1M in monthly revenue. Whenever challenges came up, we solved them together efficiently, and Kevych Solutions continuously adapted and grew alongside our projects.We highly recommend them to anyone looking for a reliable, high-level mobile app development partner.

He was always responsive and proactive in managing the work, which made the entire process smooth and stress-free.The team was professional, reliable, and genuinely committed to quality. They understood my requirements and provided valuable input that improved the final product. Highly recommend this firm for anyone seeking skilled developers and excellent project management!

Web Development Review from Philip Wilson
ELEK+RIK team provided a streamlined process that was both simple and enjoyable. They kept to the budget and communicated well throughout the project. ELEK+RIK comes highly recommended and we would work with ELEK+RIK again if given the opportunity.
George McKerrow CEO at Ted's Montana Grill
5.0★
Mobile App Development Review from George McKerrow
ELEK+RIK has worked on improving our React Native mobile app. We had the skeleton of an app, but they were able to do an end-to-end re-design of each of the main pages. Since then, they`ve successfully implemented around ~20 different features on our mobile app. We share a spec and design, they provide an estimate and occasionally some design options, then when completed create a PR on GitHub. Their code is well-organized, easy to follow, and rarely do we have to go back-and-forth about bugs. They are also excellent communicators - carefully following threads on Slack, effectively communicating design and engineering tradeoffs, and even producing a 10m Loom video walking through a diagram. Their communication is top-notch. They are super easy to work with even though we are on very different time zones. And, I am impressed at the speed and execution of their development.
John Riley Executive Vice President at MediaCentric

Web Development Review from John Riley
ELEK+RIK was tasked with creating a website for our company from scratch. They were professional, communicative, and dedicated to delivering an exceptional website that perfectly captured the essence of our company while exceeding our expectations. They are a talented, reliable, and customer-focused web design and development company that I would highly recommend to anyone.

Karan Magu Founder at Emerge Intercontinental Pvt Ltd
5.0★
Mobile App Development Review from Karan Magu
It's been an absolute pleasure to work with Sunny and his team at Quokka these past couple of years on myweb - an interface for organizing personal digital activity. Couldn't have chosen a better technical partner to bring my vision to life. This compact yet extremely capable team are the ones who transformed a mere sketch on a piece of paper into a proper and performant software, which I would say works as well as any global software you may have installed on your device (often created by large venture funded team of engineers). I found Sunny after having a poor experience with the quality produced by a previous software development firm, and was instantly convinced by his professionalism and intelligence. I've worked with the team across multiple domains - whether it's iOS Swift and working on a complex share extension for iphones, or Kotlin for Android, or backend work for syncing data, or making a desktop client, even UI/UX design - and would wholeheartedly recommend them to anyone looking for a transparent, trustworthy and capable young team in the realm of software dev. One thing I really appreciated is the regular updates and check ins from their end at each step of the journey, which keeps things clear and transparent.

Yohami Zerpa CEO at NOWWA
5.0★
Mobile App Development Review from Yohami Zerpa
Our collaboration with Techtose was focused on developing a comprehensive web application aimed at enhancing our customer engagement and streamlining internal processes. The scope of work involved several critical phases, starting from concept to deployment. Requirement Gathering and Analysis: Techtose worked closely with our team to deeply understand our business objectives and user needs. This involved detailed workshops and interviews to gather functional and non-functional requirements.Project Planning and Strategy: They devised a robust project plan, outlining timelines, milestones, and deliverables. Their strategic approach ensured alignment with our business goals and efficient resource management.Development: The development phase included building a scalable web application using technologies such as React for the front-end and Node.js for the back-end. This phase was executed in iterative sprints, allowing for timely feedback and adjustments.Testing and Quality Assurance: Rigorous testing protocols were implemented to ensure the application was robust and bug-free. This included unit testing, system testing, and user acceptance testing.Deployment and Training: They managed the deployment to our cloud infrastructure and provided comprehensive training sessions for our team to ensure smooth adoption and operation.Post-Launch Support: Techtose provided ongoing support post-launch to address any issues and implement enhancements based on user feedback.Throughout the project, Techtose maintained excellent communication, providing regular updates and adapting quickly to any changes in requirements. Their dedication and expertise were evident in the quality of the delivered product, which met all our expectations and helped us achieve our strategic objectives.
Nenad Backovic Founder and CEO at Digital Version DOO

Software Development Review from Nenad Backovic
The Discovery phase spanned several weeks, during which the Techtose team guided us through a series of insightful and challenging exercises that deeply enhanced our understanding of our product's requirements. We conducted an in-depth analysis of both local and international competitors and examined the technical aspects of our product's vision, identifying the key areas that needed the most attention.The final deliverables included a comprehensive Scope document outlining the details of our Discovery phase, an initial UI/UX prototype, site maps, and an extensive user stories document.The professional was phenomenal, there was never a time we had to follow up with Techtose and the team for an update as they were always communicating with us regularly.It's hard to express in words how Techtose and the entire team truly feel as if they are part of our company. It is rare that an organization can create a feeling of not only extreme competence but even more importantly trust in such a short span of time. As a founder starting out, I was challenged, I was pushed and I was given support by Techtose Software Solution the same way my other co-founders have been throughout our journey.At times we truly felt that Techtose cared more about our success than maybe we did. Not only do they have a deep understanding in their field of software development, but they possibly have a deeper understanding of what a successful product should encompass. I can't recommend them enough; if you are at any stage of your journey you must reach out to Techtose Software solution pvt, you owe it to yourself.The final result gave us a clear, well-defined scope for our MVP, which will serve as the foundation for developing our platform. Each deliverable exceeded our expectations. We are excited to continue our partnership with Techtose as they assist in the development of our platform.

Web Development Review from Oleksii Shapran
Techtose helped us in developing our website as we embarked on a transformative journey by enlisting the expertise of a dedicated team to oversee the maintenance and enhancement of our WordPress themes. This strategic move not only involved meticulous care for our digital ecosystem but also encompassed a holistic approach, encompassing site migration, refining onboarding processes, bolstering post template enhancements, and optimizing the underlying codebase for enhanced efficiency.Techtose team are attentive to details, efficient and have good communication skills. I recommend partnering with them because they're a good team.

Software Development Review from Chaya Tanna
The company was taking over from another software company, and it was a lot of work for them to initially understand what they were taking on. The communication was great if I wasn’t happy about something, they would always try and do something to ensure they delivered exactly what I wanted. Sometimes when you are spending your own money, it’s hard to not have the scope creep they hold you accountable to ensure success. I would definitely work with Moby again.

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%
