IT Services Review from Taras Oliinyk
The project involved developing a mobile app for an e-commerce client, with U1CORE building the marketplace and WEZOM responsible for the mobile application. Both companies worked as partners on the same product, so the mobile app had to fit naturally into the marketplace's functionality. WEZOM brought solid mobile development expertise to the project and built the application around the marketplace requirements. Their team was able to work within the shared product setup and keep the mobile functionality consistent as the project progressed. We would be happy to work with WEZOM again on similar projects!

eCommerce Development Review from Ivan Usenko
We involved WEZOM to support the technical side of a U.S. e-commerce client's advertising setup. Our team handled PPC and marketing, while WEZOM implemented server-side tracking and profit-based ROAS attribution.Their technical work fit well into the client's existing setup and gave us a more reliable view of campaign performance. This made it easier to assess results and adjust advertising spend accordingly. Overall, we had a positive experience with WEZOM!

eCommerce Development Review from Max Zakhozhiy
For one of our jewelry e-commerce clients, WEZOM took care of the website development while our team handled its promotion. The teams coordinated well throughout the project, especially on technical requirements that could affect the websites future promotion. WEZOM was open to our input and made it easy to align development with the client's marketing needs. The finished website gave us a good foundation for ongoing promotion, and we were happy with how the two teams worked together. We'd be glad to collaborate with WEZOM again.

Mobile App Development Review from Matic Debelak
Workstream 1: research and product strategyWorkstream 2: ETP release Technology : Vendor use Flutter framework, which allows one programming language and one codebase to create two different apps (for iOS and Android). 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.

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!

Web Design Review from Patrice Archer
They developed a SaaS web platform with smart scheduling and automation tools for us at and built the platform's front- and backend and integrated a custom analytics dashboard and calendar integrations. But to be honest what impressed us most was how deeply they engaged with our vision. They didn't just write code they challenged assumptions, proposed better workflows, and contributed as if they were part of our internal product team. Their ability to think strategically and focus on user experience made them feel more like tech partners than a typical outsourced vendor.

Software Development Review from Harshal Chhajed
They have highly skilled support staff for faster resolution which leads to customer satisfaction. Also, it has many features including IoT and blockchain apart from regular software development. If there are any changes in the scope of the project at a later stage, it can prove quite costly and also difficult to accommodate last-minute client-side scripting changes. They are versatile, cost-effective, and offer quick customer support. They offer a very customized software development tool where business needs can be addressed. It is very cost-optimized and hence can help generate good returns for business investment.

Startups Software Development Review from Justin Collins
Our first engagement with Twenty Ideas was accurately scoped and allocated from day one, and that was impressive. Being on time and budget while exceeding expectations seems impossible for many vendors, but with Twenty Ideas, there were zero issues. They anticipated our needs and presented clear options when necessary.

Mobile App Development Review from Rachel Efron
The most impressive thing was the collaboration we established. I had been creating this app by myself for so long, and all of a sudden, I had a whole team of thought partners. Twenty Ideas really got in there with me, learned what I was trying to make, and collaborated with me on it. It was an extremely rewarding experience, and we're thrilled with the app!
Jana DiSanti's Review Sourced from Google
I started working with Twenty Ideas in a part-time consulting capacity, but I became so taken with the team’s passion, mission, and supportive culture, that I ended up applying for a full-time position. I’ve been with the team for three and a half years now, and it’s given opened doors to expand my skill set; work with smart, kind, and dedicated people, every day; and work with clients who truly care about making a positive impact, to create life-changing solutions together. It’s a great place to work!

Elliot Jacobs's Review Sourced from Google
We run a SaaS platform for PR reporting. It’s our first time working with an external development team after years of in-house. We made the shift to get more flexibility and to have dedicated capacity for building out a suite of new features on top of our product.The work is R&D by nature, so specs change, and priorities shift. Clockwise Software has always been flexible about that and scaled up when we needed more people involved. What else stood out is the team's experience. Our codebase spans multiple services with a fair amount of legacy code. They have people who've clearly worked across different codebases before, and it showed in how quickly they got productive.Our engagement is ongoing. We launched the new features, ran a beta, and opened it up to the full market. ARPC has increased since launch, a clear sign to us that the work landed well with customers.
Lukas Nchimbi's Review Sourced from Google
Hired them to build an AI feature on top of our internal system, basically an assistant so our team could ask questions and get info from our data instead of digging through it manually. Took about 8 weeks. Works exactly how we needed it to. Their team was upfront about the limitations early, which I actually respected.

As fellow Colorado Companies to Watch winners, our team met Amanda and her team in 2022 and its been a match made in heaven! We have our own in-house development team that is swamped with working on our web application, Kanso, and did not have the bandwidth to work on sub-applications and portals. Here's where AppIt came in to save the day!We are closing out our first project with AppIt, and we are more than impressed. The application is clean and beautiful. Their team has been a joy to work with and I look forward to our check-ins on progress. This project has been so successful we have lined up a handful projects to continue this business relationship.Kanso Software is very grateful for AppIt!

I have worked with AppIt Ventures on two different enterprise size solutions. Throughout my career and have worked with several development teams. AppIt Venture stands out above the rest.The extraordinary service provided by AppIt Ventures starts at the top, with their CEO Amanda, and is executed throughout the entire team. It’s clear their employees are empowered to make decisions, take care of their customers, and provide the customer service their leader promotes.Kayla, our outstanding project manager is creative, reliable and detail-oriented offering guidance and support to ensure all of our development’s needs are on track and being done with our greater vision and application needs in mind. If any bugs pop-up, which is bound to happen, AppIt's team is on it and has the issue quickly fixed or a solution put into place within hours. With AppIt's development team, I have peace of mind knowing we can quickly and easily adjust to our customer's requests and provide an unparalleled customer and participant experience.I highly recommend using AppIt Ventures and look forward to continuing my partnership with them.

Igor Caleta-Car's Review Sourced from Google
I worked at Decode for about a year, and during that time I had the chance to meet many wonderful colleagues who helped me grow professionally and learn new skills. Because of the nature of my role, I also had the chance to collaborate with clients across Europe, the USA, and the Middle East, and even visit some of them in person.The team I worked with was everything you could hope for - driven, proactive, and always willing to jump in and help. The development teams I was part of were well-balanced in both skills and personalities, led by highly experienced engineers who lead by example.Beyond the projects themselves, the company culture stands out. People are friendly, and the leadership is focused on sustainable growth while supporting employees development. Decode isn’t afraid to promote talent and encourage people to step outside their comfort zones in order to grow.The office is also in one of the best business neighborhoods in Croatia, with plenty of variety for employees nearby.Overall, I highly recommend Decode as a great place to work!
Marianne Van den Ende's Review Sourced from Google
Working with DECODE has been a great experience so far! Their team is skilled, flexible, and always open to collaboration, which makes the process smooth and enjoyable. Their modern design approach aligns well with our vision, and they show a real commitment to delivering a strong final product.What we particularly appreciate is their willingness to engage and adapt as the project evolves. While some aspects require additional clarification along the way, they are always receptive to feedback and ready to adjust accordingly. The overall working atmosphere is positive and professional, making them a great partner to work with. Looking forward to the second half of our project!

Fantastically positive and driven team who on every interaction you just know care deeply about a) what they do b) what they deliver and c) ultimately the experience the end user will have.Hugely impressed with their personal, creative and energy driven approach at the pitch stage, I commissioned 3SC to help us better scope an app. Their task was to take an in-house developed app prototype, and turn it into a fully fledged technical specification with user stories, MoSCoW prioritisation, costs, and an updated look and feel; all done with audience need at the heart.Myself and the wider team have nothing but very good things to say about 3SC. When reflecting on an agency to work with, loads say they can do it, some can actually do what they say they can do, even less do it in the spirit of real partnership and mutually respect/drive. 3SC do all of these excellently. I highly recommend them.

Cross-Platform App Development Company Hiring Guide
What is a cross-platform app development company?
A cross-platform app development company is a company that offers a seamless approach to mobile app creation. It goes beyond the traditional method of building separate apps for iOS and Android, opting instead for a single codebase that utilizes cross-platform frameworks like React Native or Flutter.
Businesses look for cross-platform mobile app development services because of these challenges:
- Low or declining brand visibility and sales
- App development using two code bases is slow and inefficient
- Updates are limited and slow to deploy
- Costly maintenance fees
- Limited app functionalities and features
With cross-platform app development companies, businesses can experience faster development times and potentially lower costs. Their framework experts ensure the app functions flawlessly on both iOS and Android devices, creating a flexible app that can reach a wider audience without the burden of maintaining separate codebases.

The team also integrated a proprietary AI engine alongside an off-the-shelf solution to create recommendation algorithms.
