Mobile App Development Review from Ewa Koltunczyk (Karabon)
I recently had the pleasure of working with Alty to develop our mobile app. We needed a developer who was able to translate my vision and provide technical guidance. The experience has been nothing short of outstanding. From the initial consultation to the final product, Alty's professionalism, expertise, and dedication have exceeded my expectations. Alty has demonstrated a deep understanding of mobile app development and was willing to go the extra mile. Their ability to translate my ideas into a seamless, user-friendly, and visually appealing app is truly impressive

eCommerce Review from Hanna Dobromyl
We brought Elogic in as an extension of our engineering team to help Akurateco scale integrations across Shopify Plus, Adobe Commerce, and custom commerce environments for enterprise merchants. Their senior engineers integrated smoothly into our workflows, covering integration development, platform customization, and technical consulting - with communication that stayed transparent, disciplined, and proactive throughout, from status updates to flagging risks early. Elogic's strength showed most in complex B2B commerce - account structures, merchant-specific configurations, and enterprise buying requirements - and in integrating our stack with ERP, CRM, PIM, and other backend systems. When priorities shifted, they adapted without friction, and for an engagement of this scope, the value was clear: their process lowered hiring risk and let us scale delivery without building that capacity in-house. The impact has been measurable: integration delivery accelerated by roughly 3040%, delivery capacity grew by about 50%, and we've been able to support enterprise merchant requirements faster without expanding headcount. This is an ongoing partnership, and Elogic continues to be a reliable technology partner as we scale.
B2B Review from Anna Korobkyna
Elogic helped us build and improve the digital experience around our enterprise cybersecurity platform, focusing on customer-facing workflows and a more scalable way for enterprise customers to manage their accounts and services. As our enterprise customer base grew, many processes still required manual involvement from our internal teams, which became difficult to scale. We needed a partner who could understand our business processes and help us build a more efficient and maintainable solution. Elogic supported us with customer portal development, account management workflows, API integrations with our existing systems, backend and frontend development, QA, and ongoing technical improvements. What stood out was their ability to understand the complexity of enterprise requirements and think beyond individual tasks. They focused not only on delivering functionality but also on creating solutions that could support future growth. Communication was clear and proactive throughout the engagement. The team adapted well as priorities evolved and worked closely with us to keep everything aligned. The result has been reduced manual effort in customer workflows, a stronger foundation for scaling enterprise operations, and more time for our internal team to focus on advancing our core security platform. This is an ongoing partnership, and I would recommend Elogic to B2B software companies looking for a technology partner to build scalable customer-facing platforms and complex integrations.
eCommerce Development Review from Julia Klotsko
We brought Elogic in to build a Shopify store from scratch for one of our clients - a project that required not just a clean storefront but deep integrations with NetSuite for ERP and Brightpearl for order management, alongside our full marketing stack. That combination of storefront and backend complexity is exactly where a lot of agencies fall short.Elogic handled it without missing a beat. The discovery phase was thorough - they mapped every integration touchpoint before writing a line of code, which eliminated the kind of mid-build misalignments that usually cost real time and money to fix. Both workstreams ran in parallel and came together cleanly at launch.The results were tangible: over 120 pre-orders in the first two weeks, 40% above target; order processing errors dropped by roughly 70% after Brightpearl automation replaced manual handling; inventory discrepancies between the storefront and NetSuite went to zero; and paid media ROAS improved by 25% in the first month simply because attribution was finally accurate.Project management was disciplined and transparent throughout - we always knew where things stood, and when requirements shifted mid-build, the team adapted without friction. After launch they stayed actively involved, optimising performance and flagging issues proactively rather than waiting to be asked.For a project of this complexity, Elogic delivered strong value for money. I would recommend them to any agency or business dealing with backend system complexity alongside a storefront build - that's where they genuinely stand out.

Flutter Development Review from Undisclosed
The company has a salesman who overpromised, but once the project started, he was never found to address the underdeliver. Since the first brief, I made clear our products two main selling points. Two years after, I have had to learn some code to look under the hood and discover a half-baked and improvised "solution". Now, I ended up with an incomplete product that fails to deliver the two main functions I requested (and was promised). On top of that, there is a lack of order in terms of naming, cleanliness, and hierarchy. I cant recommend them.

Sarosh and his team were top notch. I can't say enough about their thorough nature and attention to detail with my project. It really fetl like having an in house development team on my side rather than an outside hire. This team not only did what was asked but continually went above and beyond to make sure that my vision was realized. I would hire them again, without hesitation!
Nathan Gould's Review Sourced from Google
I have been working with Pendoah for AI staff augmentation since December 2025, and the experience has been excellent. Their team integrated quickly with our workflow and delivered high-quality work from day one. Communication has been smooth, and they’re very responsive whenever we need support. Highly recommend them if you're looking for reliable AI talent.

ISBX is a very professional and talented web development company. The overall experience I had with them in the redesign of our website was outstanding. They were extremely creative, provided viable options at all junctures, and delivered on time and on budget. ISBX also provided a very hands-on, and professional team who understood our need for brand engagement and outreach to a new audience with our website refresh. The team also optimized the new site for mobile usage which was very important to us. ISBX successfully executed our complex project efficiently, with excellent communication and attention to detail at every step. I wouldn't hesitate to work with them again.
Kim Farley's Review Sourced from Google
ISBX helped us from concept to launch without any issues. They were communicative, patient, and able to quickly implement solutions to project changes that came up along the way. We appreciate that they took the time to hold our hands with explanations and detailed questions to make the process as stress free as possible and to get a good understanding of our product.
Tony Alfaro's Review Sourced from Google
I've been a client of ISBX for nearly three years. They are hands down the best development firm I have ever worked with. They are on budget and on time consistently. They are trustworthy, highly communicative, and very versatile. Nothing is in the "too hard box" for them.

WOW! Working with Crema was a dream come true -- literally! Rarely have I had the opportunity to engage with a partner who so actively listens to its client's vision, considers ways address the request, then magically brings it to life with such finesse... that's exactly what Crema did. With a tight turnaround time and a very public launch, Crema created a beautiful user interface, backend database, and promotional display that activated my product and made it fun and easy to use while perfectly representing my brand. I am so grateful to Crema and will continue to seek opportunities to work with this innovative, creative, and positive group of professionals.
Evan Harmon's Review Sourced from Google
Every experience I've had with Crema has always been a positive one. And every employee I've met there have been incredibly nice, thoughtful, and great to talk to. They have a very cool office space in the Crossroads with great views of KC that just makes you want to hang out there! Crema seems to highly prioritize their company culture by putting on events and having a heathy work/life balance. In short, they seem to really care about people and that carries into their work, judging by how I was able to see their process for developing solutions for their clients at a workshop they held. Using the design sprint methodology, and healthy doses of design thinking, humanistic perspectives, diversity, and pragmatism, they clearly have spent a great deal of effort honing a highly efficient development strategy that makes finding creative solutions a reliable science. It gave me a lot of ideas to bring back to my own projects and meetings! I definitely recommend their design sprint workshop and can only imagine they would be a great company to have tackling your company's challenges.
Travys Keto's Review Sourced from Google
The Crema office is very cool. Lots of modern touches with a great view of the Kauffman Center for Performing Arts. I recently attended a Design Sprint workshop and had a great time! It was a unique experience and a great tool for solving even the most complex problems. I'm hoping to utilize it in my current role. Justin was a great facilitator and I would recommend using Crema for any Design Sprint needs or even attending the workshop yourself. It was also a great networking opportunity. Highly recommended!

Caring Gene's Review Sourced from Google
Troy Web took over the maintenance and service contract for our in depth healthcare career information and job posting website. Their ability to seamlessly take ownership, clean up and bring our site into a stable wordpress environment was done not only quickly, but also flawlessly. During our time with Troy Web, a number of updates and additional features were required to be built. They were not only able to build these aspects, but also to correct past build issues in the process making the site more reliable on a daily basis. In the last 6 months of their service we didn’t experience any unforeseen downtime with our website, which is extremely important to the function of our site for those that access and use it on a daily basis. Troy Web provides an exceptional service with a team that is always available and very knowledgeable.

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%).

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.

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:
