Kreante Reviews & Testimonials
eCommerce Development Review from Stephane Baudry
Kreante handled the full design, development and SEO of our Shopify store from start to finish. I was especially impressed by their responsiveness and the quality of their communication, which kept the project moving quickly and made the whole collaboration easy to manage.
Mobile App Development Review from Xavier Vernin
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.

Designli Reviews & Testimonials
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.
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.

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%).

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?
