    • Jimmy Caldwell
      Jimmy Caldwell COO at BedMatch Pro
      4.8★

      Web Development Review from Jimmy Caldwell

      Chop Dawg was the strongest development team I’ve worked with in 18 years of software implementation. They took our complex AI-powered senior placement platform and turned it into a functional marketplace with dashboards, business rules, CRM integration, and an AI assistant. The team listened, adapted, communicated often, and treated our vision with real care. The handoff had a few gaps, but overall, they delivered exceptional work.

      Design Services Review from Nathan May

      Chop Dawg delivered wireframes, high-fidelity screens, a logo, and Figma files while keeping each week’s work clear. They felt like part of our team, brought fresh ideas, and pushed back when needed. The experience was strong overall, though a more detailed final review would have been helpful.

      Web Design Review from Anonymous

      Chop Dawg turned our early idea for a visual polling and decision-making platform into a prototype we could confidently share with others. It made the product much easier to explain, gave us something real to test with users, and supported more productive investor conversations. The work also helped our team get aligned on the product direction, development scope, and MVP roadmap. Their team was responsive, organized, and easy to work with throughout the process.

      Mobile App Development Review from John Laporte

      Designli helped us define the requirements, features, and user experience for an app for our motorcycle organization. They produced technical documentation and a clickable prototype covering navigation, member tools, and safety features. They were responsive, delivered on time every time, and turned our broad concepts into something people could actually click through. The prototype got our stakeholders aligned, earned internal approval, and set us up for engineering, and working out design questions early should save us rework later.

      Mobile App Development Review from Brandi Heffner

      Designli built our SaaS product from scratch, using AI to speed up development, with AWS and Cloudflare in the stack, and they also handle our hosting and maintenance. We had a working MVP in just 30 days and have kept adding features since. In the first 60 days they went beyond what we expected, largely because they took the time to really learn our business and our market. Coordination through Basecamp and Google Meet has kept everything organized.

    • Thomas Simmons

      5.0★

      Mobile App Development Review from Thomas Simmons

      Designli took over app development and marketing for our driving school, with the goal of building a product we could eventually offer to other schools. Within two and a half months, the app was up and running in our own school. Their project management is excellent, and they push back constructively, thinking through what we actually need instead of building every request as-is.

      Kreante built our mobile and desktop app for a construction marketplace platform, handling UX/UI design and database setup from the ground up. What impressed us most was their expertise with no-code and low-code tools, combined with real flexibility when our requirements shifted. Their professionalism, responsiveness and communication were excellent throughout.

      Web Development Review from Chloé Fernagut

      We had a complex app to build and no technical lead, so Kreante helped define and deliver it—UX, a Bubble front end, a Xano backend, integrations and automations. They shipped on time, fixed the few small bugs fast, and frequently went beyond scope. Their integrity, quality and value for money really stood out.

      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.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

      UI/UX Design Review from Anonymous

      Azumo helped us migrate our existing UIs into a new framework, creating reusable components and the infrastructure needed for future development. The developer they assigned became a seamless part of our team, always punctual, responsive, and a great fit overall.

Frequently Asked Questions About Software Testing Companies

What services do software testing firms provide?

Software testing companies provide different testing services to identify errors, security risks, performance issues, and how the software behaves in real-life situations and across devices. As part of their software testing service, they also check if each feature works as expected, fix bugs, make improvements, and make sure new software development updates don’t break existing functions, so the software quality remains stable. 

Core services include: 

How much do software testing services cost?

Hourly rates for QA testing range from $25 to $200+. The final cost is determined based on the size of the software or application, its complexity, required testing type, tech stack (custom-built and older legacy systems cost more), and niche.  

The rate will also depend on the seniority of the software tester. Across the United States, junior quality assurance (QA) tester may charge $70 to $110 per hour, while the rate for a senior QA mentor and automation engineer can range from $130 to $200 per hour.   

Special software testing services such as QA audit goes from $5,000 to $25,000. 

How can businesses know what type of software testing do they need?

Businesses can determine what type of testing solutions they need based on the potential impact of failures and the likelihood of defects. Namely, if they encounter:  

  • Core functionality issues: Use functional testing to verify features work as expected 
  • Unstable code or new features: Use unit testing for individual components and integration testing for modules working together 
  • Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing features 
  • Performance and load issues: Use performance and load testing to evaluate speed and scalability 
  • Security issues: Security and penetration testing are commonly used across apps handling sensitive user data 
  • Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end users 
  • Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versions 

There is also the option to choose between manual and automated testing.  

Is automated testing more expensive than manual testing?

As an investment, automated testing is pricier than manual testing but offers a lower cost-per-test over time as it can run the same scripts repeatedly, without human intervention. Conversely, manual testing entails lower upfront fee, but its cost grows linearly as the project grows, as every test cycle requires paid hours from QA testers.  

So, for short-term projects or ones with shifting requirements, manual testing is considered a more economical option, whereas for maintenance and regression cycles, automated testing grants better return on investment. 

The main distinction between these methodologies is that manual testing relies on human observation and interaction to identify defects, whereas automated testing uses software scripts to compare outcomes against predicted results.  

Manual testing is best suited for exploratory testing, usability assessments, ad-hoc bug hunting, and minor hotfix verifications where script development would be inefficient. Automated testing, on the other hand, is primarily used for regression testing to make sure the new code does not break existing features. 

How do businesses measure the effectiveness of software testing?

The effectiveness of the software testing is measured via: 

  • Code coverage: The percentage of the code that has been tested 
  • Defect density: The number of defects found per unit of code 
  • Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective tests 
  • Time to detect and fix defects: The time it takes to identify and fix software defects and software bugs 
  • Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase
