My relationship with Troy Web Consulting began in 2019, and I am very proud to say it still continues. Their experience and expertise is second to none, and their incredible customer service makes communication between you and your project manager and the team something you look forward to. It has truly been an enjoyable experience growing my company with the help and abilities of such a great group. A special thanks goes out to Anthony and Mark, two of the best to work with.
Caring Gene's Review Sourced from Google
Troy Web took over the maintenance and service contract for our in depth healthcare career information and job posting website. Their ability to seamlessly take ownership, clean up and bring our site into a stable wordpress environment was done not only quickly, but also flawlessly. During our time with Troy Web, a number of updates and additional features were required to be built. They were not only able to build these aspects, but also to correct past build issues in the process making the site more reliable on a daily basis. In the last 6 months of their service we didn’t experience any unforeseen downtime with our website, which is extremely important to the function of our site for those that access and use it on a daily basis. Troy Web provides an exceptional service with a team that is always available and very knowledgeable.

Bradley Collins's Review Sourced from Google
Working with the guys at Espresso Moon (Scott, Doug, Tim and Dwayne) was truly a great collaboration and experience. They didn't just throw a website together for us, they helped us to reinvent ourselves. They go out of their way to get to know you and your business to the fullest extent, and that is a quality that is not often seen. If I were to recommend a web design/hosting company to anyone, Espresso Moon would be the one and only name I give. Thank you for your service and support!
Meredyth Jones's Review Sourced from Google
I worked primarily with Scott, Tim and Doug to build a fairly complicated site: Paypal/credit card payments, video training modules, a graded quiz, and issuance of a completion certificate. They were the only website company that invited me to an in-person meeting and that was tremendously helpful in me understanding how they work and them understanding my goals. Large Animal Consulting & Education launched 2 days ago and the site is running smoothly. I'm very happy with the site they designed (they also designed my logos) and am looking forward to using them to support and add to the site down the road.
Caleb Schallert's Review Sourced from Google
Doug Wheeler is the owner of Espresso Moon and he has provided my small business excellent IT technical support for our website. His team helped me out by removing malicious code that was affecting my site right after the Heart Bleed epidemic last year. He got my site back up and running so i could continue business and save my online reputation. I would recommend Espresso Moon LLC to anyone in need of a new website or mobile application because they follow through with what they promise to do, on time and on budget. They are truly a pleasure to work with!

Mobile App Development Review from Malik Boyd
Chop Dawg helped us turn our gifting app concept into a working prototype, handling wireframes, UI design, coding, data storage, and automation from scratch. Their team has been transparent, proactive, and highly responsive throughout the process. They provide clear schedules, flag issues early, and keep us informed at every stage. We’ve been very happy with the prototype so far and are excited to move into full iOS and Android development.
Mobile App Development Review from Anonymous
Chop Dawg took our iOS app from concept to launch, handling design, development, AWS, and App Store requirements. Their team was responsive, practical, and highly supportive throughout the process. They also stayed involved after launch with updates and fixes, and even helped promote the app through their network. Their support contributed to strong early growth and helped position the company for a later acquisition.
Web Design Review from Anonymous
Chop Dawg supported us with UX/UI design for a new fintech web application. They took the time to understand our users, product requirements, features, and overall vision before moving into design. Over a 6 to 7 week engagement, their team shared regular Figma reviews, incorporated feedback quickly, and stayed highly responsive. They finished ahead of schedule with no budget issues, and the internal response to the final designs has been very positive. Their attention to detail, professionalism, and ability to keep the process organized made them very easy to work with.

We recently completed a solution design project with Geeks, and I can not speak highly enough about the service we received. Geeks really are experts are making the complex appear (relatively) simple. Through a thorough and detailed solution design process, we created a prototype product that met all of our requirements. Geeks focus on producing visual representations of the product you are seeking - which is a far more efficient and helpful way of solution designing (as opposed to a written specification). Thank you very much for your support once again and I look forward to working together again in the future! Bradley (Associate Director)

Christine Ingram's Review Sourced from Google
I’ve thoroughly enjoyed working with the Spiral Scout team. I discovered Spiral Scout after having had negative experiences with two previous web developers. I’d worked with a designer on a Figma file and needed it to be translated to a Shopify site. From start to finish, the team demonstrated professionalism, creativity, and technical expertise.In terms of design, I couldn't be happier with the outcome. The team remained faithful to the original files. This was especially key given that a lot of time had gone into designing the Figma files. Where it was necessary to make deviations, they made recommendations that aligned with my brand and translated it into a beautiful online presence. Towards the end of the project, a particularly challenging design issue arose that was difficult to crack. The entire team, across functions, was committed to the process and ultimately figured out how to solve the problem.The communication throughout the entire process was also great. We had weekly meetings to review progress and troubleshoot any concerns. As someone new to web design and e-commerce, they took time to explain the process and were patient in answering my questions.I highly recommend Spiral Scout to other companies in need of building a Shopify site.
Bill Cummings's Review Sourced from Google
Working with Spiral Scout was a pleasure, and I am very happy with the results. As a non-technical solo founder, I relied heavily on their experience in and best practices for translating business ideas into prototypes, and they were consistently patient, creative and attentive as they guided me through the process. The professionalism of their final deliverable speaks for itself and I look forward to working with them again soon to start building the actual product.

Flutter Development Review from Undisclosed
The company has a salesman who overpromised, but once the project started, he was never found to address the underdeliver. Since the first brief, I made clear our products two main selling points. Two years after, I have had to learn some code to look under the hood and discover a half-baked and improvised "solution". Now, I ended up with an incomplete product that fails to deliver the two main functions I requested (and was promised). On top of that, there is a lack of order in terms of naming, cleanliness, and hierarchy. I cant recommend them.

They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

Software Development Review from Daniel Rondell
We are notably satisfied with the upshot. PMs and development team was very devoted to the tasks and encouraging. We had a stringent and fixed deadline. And we got it just in time! KitRUM helped us to create an entire software that absolutely meets our requirement. They had presented the system in a short-term after putting their hands on it. They also provide support after developing this software. We have a different project now and certainly will work with KitRUM again.
Software Development Review from Adelina Romanova
KitRUM expanded our team to shift software to a new platform. Using JavaScript and RESTful APIs, they improved interfaces and DevOps, and fixed bugs. The team has always been on time. Their ability to understand the business requirements and their communication was just perfect. I definitely will recommend KitRUM as a reliable partner.
Software Development Review from Daisy Skot
KitRUM made a variety of development services: conception, coding, and QA, which means almost a full software package for our company. We needed to develop a few tasks, for example, a desktop app for our store, a cloud app for administration and supervision, and a portable app for end customers. However, we had an in-house team, which is not enough for this project. So we had to find a dedicated team that could deliver all we needed. We found KitRUM as a top-notch software development company

Wearables Review from Issac John
A global OTT provider - Discovery+ earlier this year, had a breakthrough launch in a cluttered OTT market like India with a differentiated product targeted at lifelong learners and passionate communities. The team at Robosoft played a significant role in building this multi-platform experience spanning iOS, Android, Web and Fire TVs. Their team comprises an extremely dedicated bunch of folks with a keen problem solving approach and under the stellar leadership of Ravi Teja, Jay Shah, Srinidhi Rao and Pooja Bal, they have been the kind of dependable partners that a lot of brands would be fortunate to have. I wish them and their team the best for their future.

Mobile App Development Review from Deepak Porayath
Our experience working with Robosoft has been quite good in terms of product and outcomes. With our CapitaStar@Work app for India business, the end goal was to bring our customers and their employees onto a digital platform. The objective was to integrate our solutions such as visitor, parking, and ticketing system management into a single app. CapitaStar@Work caters to our requirements and surely will make life simpler for our users. I would recommend Robosoft to others because it is a good organization to implement technological interventions in any traditional manufacturing, real estate, or brick-and-mortar industry.

Software Development Review from Daria Stolyar
We hired Altoros engineers as an essential extension of our client-facing internal teams. This was a tough decision because our reputation as a brand depends on the overall efficiency of our processes and we needed to make sure all risks are mitigated when it comes to delivery. Altoros has not let us down.Together with Altorosians we successfully deployed a number of tough and technologically complex projects on time. So our collaboration is certainly set to continue.
Software Development Review from Victoria Lewis
We enjoy working with our team, Roman Yurkin, Tatyana Kobzar, Svetlana Kalchanka and Tatiana Anop. They bring expertise and immense value to our business with each piece of work they complete. They are a major part of our business development and delivery.
Ruby on Rails Review from Greg Lipper
In my 30 years in the software business, I have never had as positive an experience with an outsourced development services provider as I have with Altoros. Each Altoros engineer we have worked with has been strong technically, estimated development times accurately, completed projects on time, and delivered code and projects with high quality. Beyond that, they have helped improve our thinking and approach with suggestions and ideas that were better than the spec of instructions we supplied.

Olive Peterson's Review Sourced from Google
You can't beat the VLink guys when it comes to designing and developing. From the start, I hired them to build my website and gave them all my specifications and preferences. I was very happy with their work and they advised me on some better alternatives where possible. Their assistance with all stages of designing and developing our website, from the first interaction to the launch, was invaluable. All of the components of the project were delivered on time, with excellent quality, and they provided satisfactory support until the end. I would recommend them without hesitation.
Ajitabha Bose's Review Sourced from Google
I have found working with VLink to be an exceptional experience despite my initial trepidation regarding establishing a relationship with a company situated so far away.The VLink experts have strived for excellence, no matter how difficult it has proven to be. After receiving a product of the highest quality, my expectations had been exceeded. I was impressed by the professionalism, responsiveness, and patience of the project manager who dealt with my requirements. Even the amount that was quoted to me was in line with my expectations. Now I consider myself to have gotten more for my money than I expected.
Sarthak Anand's Review Sourced from Google
We experienced a breath of fresh air when we switched to VLink's Managed Solution. They carefully analyzed our entire ecosystem and offered multiple recommendations for improving our system (not just one). They also implemented various cost-saving measures. We incrementally upgraded our equipment and software solution as needed. You can choose from a variety of options, and they will work according to your timeline, your needs, your budget, and your staff's ability to change. I have not detected a lapse-in fact as far as knowledge is concerned, and I have learned much from them! Which is of particular importance since we work around the clock.
They help businesses reduce release risks, enhance user experience, and strengthen security posture by ensuring that the finished solution meets industry and business-specific standards.
In fact, research found that fixing bugs before product release results in 6.5x less cost than resolving the issue after launch.
Moreover, automating load and performance tests can accelerate the regression testing timeline by up to 90%.
Gartner’s study also found that the top reasons that organizations use automated testing are to improve product quality (60%), accelerate deployment speed (58%), and enhance department agility (41%).

Before hiring a US software testing firm, consider asking these questions:
Selecting the right testing partner requires careful evaluation beyond surface-level factors.
Common mistakes include:
When asked about the most significant challenges to automated software testing deployment, struggles with implementation (36%), automation skill gaps (34%), and high upfront costs (34%) were among the most commonly reported.
Per the State of Testing Report, these are the most common metrics businesses are using to measure a software testing team’s effectiveness:
Rated 4.8 on Google and 4.7 on Trustpilot, DesignRush Agency Directory is a reliable resource for finding software testing companies in the United States. We owe this to our executive selection team, which follows a strict screening process when featuring agencies on the platform, assessing key performance indicators, like portfolio, client reviews, and industry reputation.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
They provide a comprehensive range of services designed to validate and improve software quality through systematic evaluation and advanced tooling.
Core testing services include:
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.
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:
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.
Beyond project scope, complexity, and timeline, these are additional costs to consider when working with software testing agencies in the USA:
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 | 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.
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:
