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.

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.

We are thrilled that we decided to work with Confianz to build our mobile app. They took the time and asked a lot of questions to truly understand why we wanted to build the app and who would use the app. The process was simple and after a few months we had a great looking and fully functional mobile app for iPhone and Android. We will definitely use Confianz to build our next phase for the app as we look to expand our market share.
Birgir Gislason's Review Sourced from Google
January 2020 Confianz took over the maintenance of our Odoo ERP system from our previous Odoo partner. Anoop put together a dedicated team who analysed our system and worked with us on a plan of improvements and upgrade of the whole platform.Our platform had been heavily customised over the years. Unfortunately lot of the custom code and apps had not been properly documented nor followed Odoo's best development practice, causing random issues and an unstable platform.The Confianz team removed poorly developed apps and website, and replaced customisation with new code following Odoo's development methodology.The result is a very stable and robust system.It is great working with them. We don’t have an inhouse development team, so we have worked with Confianz using dedicated fulltime resources. It is same as having your own highly experienced IT team with extremely good understanding of the whole Odoo platform.All work is well managed with weekly review meetings, where the team reviews progress and demonstrates work in progress. This is very useful setup because it enables direct communication with the development team and identifies quickly any gaps in requirements and the solution.I highly recommend Confianz. The development team is highly experienced and clever bunch. They will tell you if you are asking for customised features that can be achieved using core functionality instead. They will not lead you down a wrong path just because you think it is the way to go.The President of the company, Anoop, is truly exceptional character and honourable man. He has built a company with great team which you can trust.
Yuri Ahn's Review Sourced from Google
Confianz was selected to be VS America’s ERP implementation partner in 2018 after they had successfully completed a custom application to improve our internal document processing. We’ve hired several different companies prior to Confianz, but unfortunately, they left all on their own terms because they were not able to find a solution.I’ve worked alongside Confianz for almost three years now and I’ve been impressed with the level of talent this company brings. Their VP of Enterprise Solutions as well as his team of developers are extremely knowledgeable, patient, professional, and respectful. Every meeting and interaction we’ve had with Confianz was a valuable learning experience.We are extremely grateful that Confianz helped us successfully go live during the pandemic in April 2020. Since going live, we had some significant improvements in our processes and we continue to work with Confianz to fine tune details. I highly recommend Confianz!

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:
