Azumo Reviews & Testimonials
Software Development Review from Michael S.
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.
Software Development Review from Anonymous
Thanks to Azumo’s work, our product is now more scalable, optimized, and ready for a growing user base. Their team has managed the engagement effectively, keeping us updated and addressing any challenges along the way. We’ve appreciated their constant availability and proactive communication.

Chop Dawg Reviews & Testimonials
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.

Leanware Reviews & Testimonials
AI Development Review from Julia Antoci
Leanware built the mobile MVP of our AI fitness assistant for iOS and Android. It started with discovery workshops that sharpened the product vision and shaped an MVP roadmap prioritizing launch features while leaving room for expansions like avatars and real-time feedback. They developed a conversational AI engine with custom prompt and context engineering tailored to fitness conversations, one that keeps continuity across sessions, remembers user progress and preferences, and keeps health guidance within safety standards. On top of that they implemented photo-based food recognition, smart search that understands fitness intent, personalized recommendations, progress tracking with AI-generated insights and coaching suggestions, and gamified response formats that make AI answers easy to read, plus the scalable backend behind it all. Their consultation saved us an estimated 20 to 30 percent in costs by avoiding unnecessary complexity, and we launched a functional MVP across the app stores in under eight weeks, faster than planned. Project management was exceptional: clear timelines, on-schedule delivery, and proactive communication via Slack, with expert recommendations guiding decisions rather than every choice being pushed back to us. Their technical skill and creativity made the whole thing feel less like hiring a vendor and more like building with a co-founder.
Software Development Review from Anonymous
Leanware delivered two significant projects for our e-commerce platform along with a steady stream of smaller fixes and enhancements. They built a new employee management page in our back office so our customers can create accounts, set permissions, and link employees to entities on their own, and when our mobile app's chat functionality needed replicating in the back office, they built a custom chat and messaging React library from scratch, integrated seamlessly with our design system and existing bespoke solution. Along the way they worked comfortably across Next.js, React, React Native, Apollo, GraphQL, and Hasura, and adapted to our implicit conventions. We ran week-long SCRUM sprints with check-ins three times a week, and they consistently hit the sprint goals on time; even when we needed hard pivots mid-sprint, they adapted without losing pace. As the engagement progressed they increasingly took the lead, asking well-informed questions and offering suggestions on code, product, and design that genuinely enriched the outcomes. What impressed us most was how swiftly they onboarded: given incomplete product descriptions, they asked the right questions to fill the gaps and picked up our undocumented code patterns without getting stuck on minor details. It felt like one cohesive team working toward shared objectives, free of the friction that usually comes with a third party
Mobile App Development Review from Anonymous
Leanware has partnered with us since Q4 2023 on two cloud-based mobile apps for iOS and Android, one built in Flutter and one in React Native, handling development on both and the UI/UX design on one. For one project they staffed a team of five mid-level developers, a senior developer, an architect, and a UX designer available as needed. They also took over an app that was unstable and nowhere near production-ready and turned it into a stable, solid product I'm genuinely proud to show. Their processes leave nothing to chance and the code that comes out of them is excellent; they've been flexible and thorough throughout. They meet deadlines, keep their promises, and are careful about what they commit to. The whole team has been great, and Alvaro, their Technical Product Manager, deserves a special mention for being remarkable. I hired them because they were upfront about what they could and couldn't do, and that honesty, together with the tremendous quality of their work, is what separates them from other providers. Both are getting harder to find these days.

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.

Mobile App Development Review from Lucas Chatham
I had an excellent experience working with this engineering firm to build a React Native app. Oleg and Ihor were exceptional software engineerstheir technical skills were top-notch, and they consistently delivered clean, well-structured code on time.What really set this team apart was Volodymyr, their CTO. He was incredibly hands-on, maintaining clear and frequent communication throughout the project. 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!

Hiring Guide: How to Choose the Best Software Testing Company in the US
What do the best software testing companies in the US do for businesses?
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%).
How to choose the best company for your business?
To choose the best US software testing company for your business, evaluate its expertise and experience against your requirements. Here are some steps to guide you:
- Define testing requirements
Outline current software issues, testing goals and priorities, project scope, compliance requirements, budget, and timeline. - Search for relevant experience
Evaluate case studies and client references to find a company familiar with your industry-specific requirements, tech stack, and testing coverage and methodology. - Conduct due diligence
Assess the company’s certifications, vendor partnerships, awards and recognitions, and client reviews to confirm it’s trustworthy and credible. - Issue a request for proposal (RFP)
Provide a detailed project brief illustrating your business's current predicaments, so that the company can provide an accurate quote that aligns with your needs. - Schedule a consultation
Meet the team who’ll work on your project and request sample reports or pilot tests to further gauge project fit. - Make your decisions
Beyond technical proficiency, select an agency that aligns with your values and is capable of supporting your growing needs with flexible team sizes and service levels.

What questions should you ask a US software testing firm before hiring?
Before hiring a US software testing firm, consider asking these questions:
Relevant Background
- How familiar are you with our industry-specific requirements? What deliverables can you provide to help us comply with the regulations?
- Can you share projects similar to our testing coverage, methodology, and criteria?
- What testing tools and frameworks do you use?
Services and Processes
- What is your software testing process — from discovery and planning to execution and reporting?
- How will you set up/manage test environments and test data?
- How do you balance manual vs automated testing? What are your criteria for automating tests?
- How do you handle access control, credentials, and confidentiality?
Relevant to Your Project
- What test types do you recommend for us, and why?
- What are your SLAs for triage, retesting, and regression after fixes?
- How do you measure quality and progress (coverage, defect trends, escape rate, release readiness)?
What are common mistakes to avoid when hiring a software testing agency?
Selecting the right testing partner requires careful evaluation beyond surface-level factors.
Common mistakes include:
- Choosing based solely on cost: The cheapest option often leads to lower quality, missed defects, and costly rework. Organizations should evaluate "results per dollar" rather than "hours per dollar."
- Failing to define requirements clearly: Vague project scopes lead to miscommunication, scope creep, and budget overruns. Clear documentation of testing objectives, success criteria, and testing entrance and exit criteria is essential.
- Underestimating testing needs: Setting up additional testing environments and infrastructures beyond the agreed scope leads to longer project timelines and higher fees. One way to avoid this is to ask the company to conduct audits, so you can more clearly define the testing needs and strategies.
- Neglecting long-term maintenance planning: Testing isn’t a one-time launch task. Without ongoing QA as the product changes, defects and security gaps reach users and become far more expensive to fix after release.
- Ignoring communication and cultural fit: Testing teams need to integrate with development workflows. Time zone differences and communication barriers can impact collaboration quality.
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.
How to evaluate the effectiveness of a US software testing firm?
Per the State of Testing Report, these are the most common metrics businesses are using to measure a software testing team’s effectiveness:
- Test coverage (56%): Compares how much of the software has been tested to determine the thoroughness of the testing process.
- Defect metrics (54%): Measures the number of identified defects, organizes them according to severity, and the rate at which they’re identified.
- Test execution metrics (45%): Monitors the speed, progress, and outcomes of running tests through test execution rate, test pass/fail/block percentage, and cycle time.
- Escaping defects rate (34%): Tracks the percentage of defects or issues identified after a software has been released.
- Test effectiveness metrics (25%): Identifies testing process performance in identifying defects and ensuring product quality before launch.
- Test economics (8%): Determines if the business maximizes the return on investment (ROI) of software testing.

FAQs for Software Testing Companies
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 | 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%
