WooCommerce Review from Amanda Viviano
We hired Qolos to build our local florist shop's website on WordPress and WooCommerce, and we couldn't be happier with the results. From the start, they took the time to understand our business and created a site that's not only beautiful but easy for our customers to browse and shop.The WooCommerce setup was seamless, our online ordering works exactly the way we needed it to. But what really sets Qolos apart is their ongoing monthly maintenance. We never have to worry about updates, security, or technical issues because they stay on top of everything. Any time we've had a question or a small change request, they've been responsive and professional.As a small local business, it means a lot to work with a team that genuinely cares about keeping our site running smoothly. Qolos has been a true partner, not just a vendor. Highly recommend them to any local business looking for reliable web design and maintenance!
Web Development Review from Sanjay Singh
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.
Shopify Review from Sarah Nesheim
Working with QOLOS was the best decision I have made in regards to scaling my business. They are professional, so creative, they communicate every step of the way and their pricing is fair for the highest quality work. The designer of our logo and website did it well and I am so impressed and proud of the final product! the designer listened and knew exactly what I wanted which made the process so simple. Seriously could not recommend QOLOS more!

Clearly defined roles and responsibilities, communication is clearly and respectfully, very effective project methodology, trying to understand every time how their activities fits into mission of Modra zavarovalnica, respect each member of team, etc.
Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.
Web Design Review from Anonymous
Thanks to Infinum's website refresh, the client has seen an almost 100% improvement in their website's conversion rates. The team excels at project management, using the client's own proprietary tool and also Figma very well. Their proficiency in design, delivery, and client relations stands out.

The team was consistently proactive, professional, and transparent. I truly appreciated their structure and ability to keep things moving smoothly. I would highly recommend working with Tepia.
Mobile App Development Review from Robert Beknazarian
Working with Tepia Co has been an exceptional experience from start to finish. They played a critical role in developing our mobile app for RELI, and I can confidently say they exceeded our expectations on every levelFrom day one, Tepia demonstrated a deep understanding of both the technical and business sides of app development. They didnt just execute tasks they asked the right questions, challenged assumptions when needed, and helped us think through complex workflows in a way that improved the final product. Their team truly operates as a strategic partner, not just a development vendor The communication was excellent throughout the entire process. We always knew where things stood, timelines were clear, and any issues or changes were handled proactively and transparently. For a project as complex as ours involving pricing logic, user flows, financing options, compliance considerations, and scalability this level of clarity and responsiveness made a huge difference.What really stood out was Tepias attention to detail and commitment to quality. The app they helped build is stable, clean, intuitive, and built with long-term growth in mind. They were thoughtful about architecture, performance, and future enhancements, which is critical for a company like ours that plans to scale aggressively.They were also extremely flexible and patient as our requirements evolved (which happens in real-world startups). Instead of pushing back, they collaborated with us to find smart, efficient solutions that aligned with our vision and budget.If youre a founder or business owner looking for a team that:Truly understands mobile app developmentCommunicates clearly and consistentlyThinks strategically, not just technicallyDelivers high-quality, scalable workI highly recommend Tepia Co without hesitation. They have been a trusted partner in bringing RELI to life, and we look forward to continuing to work with them as we grow

Flowty is a blockchain-based platform providing various transaction services around NFTs. K-Optional wears many hats in support of Flowty including Front End, Back End, business strategy, SEO and more.The K-Optional team has been incredible to work with. They are proactive, supportive, smart, thoughtful and, most importantly, fit seamlessly into our team and company culture. To put it succinctly, we tried to hire them full-time...and then tried to buy their company to acqui-hire them.Some of their strengths include: reliability, responsiveness and creativity. There are many groups out there that can perform some version of the work we are looking for. There are not many groups that are responsive at all hours of the day, deliver consistently and able to present data-backed business strategies.

Yolanda Torres's Review Sourced from Google
RUN AWAY from this company! Supposedly located in California. They sold me a package to design the branding, website, and social media for my company for $1500.00. "EVERYTHING" for $1500.00. Have paid over $6000.00 and I have NO control over the material I paid for. They send you everything in formats you cannot use or convert. They want to keep a hold of you to keep asking for money!!!!!! NEVER send anything to print through them!!! Ordered some business cards and brochures and have never received the brochures. To this day I have not received a single invoice or receipt of anything of what I have paid, including the design of the logo, the purchase of the domain and many other things. DO NOT RECOMMEND.
David McCurrach's Review Sourced from Google
I believe this company is a criminal enterprise. They are also known as Creative Company and Sketch Profs. Creative Company made a $2,500 unauthorized withdrawal from my checking account. When I protested the transaction, Uptown Logo Design provided a fake receipt, fake transaction and activity logs and fake emails supporting the charge to my account. It was an elaborate and thorough fraud. I'm sure they've used similar fabricated documents before with other people they've ripped off. I reported them to the FTC and FBI.

They didn't just throw a website together for us, they helped us to reinvent ourselves. They go out of their way to get to know you and your business to the fullest extent, and that is a quality that is not often seen. If I were to recommend a web design/hosting company to anyone, Espresso Moon would be the one and only name I give. Thank you for your service and support!

I worked primarily with Scott, Tim and Doug to build a fairly complicated site: Paypal/credit card payments, video training modules, a graded quiz, and issuance of a completion certificate. They were the only website company that invited me to an in-person meeting and that was tremendously helpful in me understanding how they work and them understanding my goals. Large Animal Consulting & Education launched 2 days ago and the site is running smoothly. I'm very happy with the site they designed (they also designed my logos) and am looking forward to using them to support and add to the site down the road.

I would recommend Espresso Moon LLC to anyone in need of a new website or mobile application because they follow through with what they promise to do, on time and on budget.

AI Development Review from Oleg Sotnikov
Diffco built a complex, production-grade AI agentic system and backend for our client's fintech platform owning architecture, AI/ML components, and AI agents in a security- and compliance-sensitive environment. They delivered on time and within budget, communicated proactively, and operated like part of our own team, taking ownership and suggesting better solutions throughout. Deep AI/ML and senior backend expertise. We'd happily work with them again.

Software Development Review from Elizabeth Sheehan
Our main goal was to update our web presence to more accurately represent our proficiency in IT consulting and services. Our prior website was disorganized, had poor performance, and failed to adequately convey our expertise in customer relationship management (CRM), customer communications management (CCM), and content management systems (CMS). We required a highly functional, aesthetically pleasing, and scalable website that could captivate users, offer smooth navigation, and blend in seamlessly with our current technology stack.They have perfect attention to detail. They took care of everything, from making sure the font and color scheme matched our corporate identity to making every user interaction as efficient as possible. The outcome was a website that serves as a potent instrument for business expansion in addition to being aesthetically pleasing. They were always helpful and quick to respond when we had questions after the launch.
Big Data Analytics Review from Adam Leeman
A3logics main strength was their intuitive understanding of what I was looking for. They were highly communicative regarding updates and required almost no guidance or oversight. Moreover, they were extremely creative in areas I hadn't even considered, coming up with impressive solutions.
Software Development Review from Mubarak Muaz
A3logic provided software development based on the detailed briefing that we gave them, ensuring that every aspect aligned with our brand identity and user needs. They carefully analyzed our requirements, conducted research, and proposed design solutions that enhanced usability and engagement. A3logic was a very professional company. They managed the project well and delivered on time and within budget. They were very responsive and timely in their communication. I was impressed with how enthusiastic the A3logic team was about their work. They cared about my project and treated it as their own. They were a great team.

Software Development Review from Rick Tomsic
Global business segment growth is requiring technology to keep up with the increase. Our platform is designed to be scalable and able to be implemented across several nations. We collaborated with Closeloop Technologies to work with our staff in order to scale up the programme.An whole agile team is provided by Closeloop Technologies to participate in our programme. At first, we gave them the data in hopes that they would aid in our execution. They have combined Spring Boot, JavaScript, and AWS cloud technologies.The platform is a value stream and full-suite insurance lifecycle. It is an internal iterative software programme.Working with Closeloop Technologies is simple. They pick up new roles rapidly and possess agile team abilities that are industry standard. The staff not only fits right in, but they also contribute their knowledge and perspectives, making them a vital component of the programme.
Software Development Review from Henrique Dubugras
Services that had been slow or unavailable for weeks had to be brought back up. We must bring back our vital business role. After learning about our issue, the Closeloop project manager assigned a senior database specialist to address it. Our main programmer had a direct conversation with the database specialist of Closeloop after they listened to our problem and asked some follow-up questions. Within less than two hours, the solution to our issue had been verified and implemented.
Software Development Review from Bill Rogers
We occasionally utilize outsourced resources to increase our team's ability to satisfy the commercial demands of our clients. This time, my goal was to create and enhance the products we were providing to clients. Their engineers joined our own team to work on the project, creating MetaTrader-based software for our traders. They assisted us in creating and refining a suite of services that give our clients more functionality; up until that point, the solution had been erratic and unconventional. Their most recent endeavor was the development of an income trading module. We employed a scrum methodology with sprint deliverables and agile planning. Along with narrative points, we also used our in-house bug tracking application for project and task management. Everything was really accurate.

Mobile App Development Review from Konrad Korobowicz
Thanks to Wdi's expertise and dedication, the music app achieved a 400% increase in downloads within the first month of launch, demonstrating significant progress and success.
Mobile App Development Review from Abdelrahman ALMULLA
wdi took the vision we had and turned it into something even better. They built this incredibly detailed app that lets users filter hotels based on things like airport transfers, car services, or other specific amenities. Travelers can also quickly spot deals or limited-time offers with just a glance.One of the coolest parts is how the app keeps guests updated when theyre checked into a hotel - whether it's on-site events or nearby activities, theyll get notifications straight to their phone. The feedback system they added is a game-changer. Guests can send questions or share thoughts right from their rooms, and they get notified the moment theres a response.
Mobile App Development Review from Aaron Birkby
We had many very clear outcomes and timelines based on our needs that were identified before the project began. They provided regular updates and progress reports via email and virtual meetings throughout the project. Typically in two-week sprints.

Web Development Review from Jaroslav Tyman Jr.
We contacted Zero Negative about a two stage renewal of our company website with a very aggressive timeline for the first stage. Zero Negative worked and guided us through pulling off the first stage within our timeline while also ensuring that the content and ideas for that stage were readily applicable to the full design. When we got to the full design, they were fully responsible for corralling the various preferences and ideas from our team into a well executed cohesive site. We're now in a good spot and look forward to continuing to work with Zero Negative as our business and needs grow.
Web Development Review from Susan E. Roberts
Zero Negative did an exceptional job designing my website, roberts-communications.com. From the start, they understood that this wasn't just about aesthetics it was about positioning, credibility, and clarity for a senior-level communications brand.They translated a complex, high-stakes business into a site that feels polished, modern, and authoritative without being flashy or over designed. The process was collaborative, efficient, and thoughtful, and they were responsive to feedback while also offering smart guidance when it mattered.The final result reflects exactly how I want Roberts Communications to be perceived: strategic, sophisticated, and trusted. I would highly recommend Zero Negative to anyone looking for a design partner who understands brand, not just web building.
Web Development Review from Anonymous
These guys are the best! We engaged with Zero Negative to develop a comprehensive web-based system for our factory that allows for managing orders, processes, and inventory. This initiative was essential for us to secure a big ticket client. We truly could not have accomplished this without their assistance. They dedicated considerable time to on-boarding and collecting the requisite information, followed by prototyping the software, and ultimately developing it from scratch. Overall, we are very satisfied.

StatCounter reports that that iOS accounts for 59.56% of the American mobile market share, while Android is at 40.46%. As such, it’s valuable to develop mobile apps according to your target users.
Mobile app development costs in the US are about $100-$200+ per hour or $15,000-$30,000 for basic projects. Apps that require more complex features and functionalities can reach $150,000-$500,000+ per project.
