AI-Powered DevOps Review from Cyril Tuzemen
We had an excellent experience working with Addweb Solution on the development of an AI-powered property assistant for Vesper Homes. Our goal was to make property searching more natural and intuitive. Instead of requiring customers to understand complex real-estate filters, we wanted users to simply describe their needs conversationally. The final result exceeded our expectations and fits perfectly with Vesper Homes' technology-driven approach to delivering a more personalized real-estate experience. We are very pleased with the outcome and would confidently recommend Addweb Solution to any company looking for a reliable development partner for AI, automation, and digital product solutions.
Software Development Review from Derick Lee
AddWeb came in clutch during a time when we were needing engineering and software development back in 2021. We worked with them for nearly 4 years with small to large contracts for full stack development. We highly recommend their team. Professional, smart, helpful and great people. We worked with them on smaller agreement all the way to $120K contracts. We highly recommend their vast levels of experiences.

Our experience with AddWeb Solution was excellent. The team built a modern, SEO-optimized WordPress website and a custom AI-powered SaaS platform for the US accounting industry.They helped automate key processes like bookkeeping, invoicing, and reporting, which reduced manual work by over 60% and improved accuracy. The platform is fast, scalable, and easy to use, and the website performs well across devices.Communication was clear, timelines were met, and the team was proactive in suggesting better technical solutions when needed. Both the WordPress site and the SaaS platform exceeded our expectations.We highly recommend AddWeb Solution for WordPress development, SaaS product development, and AI-driven web solutions.

Mobile App Development Review from Laura Waniuk
During my tenure at Beaver Creek Resort Company I was tasked with building and launching a guest-facing app for the hundreds of thousands of visitors to Beaver Creek Mountain. I worked very closely with Quartus Technology and their team to meet the budget, the timeline and all the required features for the project. The app launched early! It's been an incredible success and the app has continued into phase 2 and 3 with added functions. I highly recommend Quartus Technology if you are in search of a quality app, strong development team and transparent pricing.
Mobile App Development Review from Chris Caputo, PMP
After looking at multiple vendors to build an app to provide information on municipalities we selected Quartus. The scope included the development of the app (including designs) and integration to a service that our development team created. Quartus was successful. They delivered in a timely, cost-efficient manner and were easy to work with. When we decided to have a second app created, we did not look elsewhere and stayed with Quartus. This app involved the development of a calculator to calculate and email title insurance premiums. Like our first app, Quartus had to develop the designs (they were able to leverage a portion of the work from our first app) and integrate to a different service that our development team created. Once again, Quartus delivered. These apps were for Android and iOS. They are a good partner.

I kept getting negative reviews about my app for technical glitches, heating issues, functionality, loading time, crashing, and more bugs. So, I reached out to QOLOS after going through 2-3 renowned review platforms. I explained my app issue to the team, and they did tremendous work with their mobile testing solutions. Also, I wanted to build a website for my app. They created a feature-rich and seamless website.

Working with QOLOS was the best decision I have made in regards to scaling my business.

Our team can easily log into the CMS and update case studies without needing a web developer, which has been a huge advantage. Our primary concern was the seamless conversion of our old templates, and RichestSoft handled this flawlessly. They even suggested ideas like making the site multilingual, though we only needed an English version, so it wasn’t necessary in our case.

Sito Pons's Review Sourced from Google
We just wrapped up a several-month project with the team at Kodexo Labs Austin and they were fantastic to work with. The project was complex, but they stayed patient, responsive, and super professional the whole time. Their team made everything feel smooth and well-organized, and the end result really speaks for itself. Definitely one of the best software development companies in Austin and we're already planning our next project with them.
Sean Peterson's Review Sourced from Google
Worked with Kodexo Labs Austin on a custom app for our delivery service, and they really impressed me. We wanted to integrate some AI features to predict delivery times and optimize routes they not only made it happen, but explained the tech in a way that actually made sense. Communication was smooth, no BS, and they stuck to the timeline. If you need mobile app development in Austin, especially anything AI-related, I’d definitely recommend them.
Georgia Andrama's Review Sourced from Google
My project was complex, I knew that going in. But what truly amazed me was how Kodexo Labs tackled the challenges in my idea and brought it to life with precision and creativity. I deeply trust Kodexo Labs as a top-tier custom software development company in Austin. Working with their team has been an outstanding experience. Highly recommended.

We recently worked with Geeks to do a scoping workshops/Solution Design for the development of a application for streamlining our reporting and surveying processes.The process from opening meeting to final wireframing was seamless. The knowledge and approach of the Business Analysts and the whole team were excellent, they listened, advised and offered thoughtful suggestions for improvements.The end specification for the application met and in many ways exceeded my expectations.Professional, friendly and smart. Great experience
Bradley Ebsworth-Willis's Review Sourced from Google
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)

Software Development Review from Tanita Custer
The development team released the project on time, considered our suggestion, and made important correction. We are very grateful to ISHIR for their help and look forward to furthering fruitful cooperation!
Kelly Stark's Review Sourced from Google
Working with ISHIR was an incredible experience. We handed them a real challenge: launch a new website with a total rebrand in a little over a month's time for a major press announcement. Our non-profit volunteer group has many voices which slows the approval process, the ISHIR team was flexible and patient.I feel they truly cared about our cause and worked hard to ensure we succeeded, ultimately delivering the site ahead of schedule. ISHIR is responsive, expert, and felt more like a dedicated partner than a vendor. I can’t recommend them enough!

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%).

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.

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:
