We are is satisfied with the engagement; Hexagon IT Solutions has delivered the web on time and within budget. The team excels in their communication and understanding of the requirements; they solve any issue that arises. Overall, they stand out for their quality work; customers can expect great service.
Software Development Review from Dominique Dujardin
The product was developed successfully and has been undergoing pilot usage. Hexagon IT Solutions managed the engagement effectively, delegating tasks and assignments between us and the team. They met timelines and communicated efficiently through Slack. Their resources also resolved bugs quickly.Hexagon makes it easy for people trying to develop software. Ultimately, Hexagon was and has been on the same page with us from the beginning. They knew exactly what we were looking for, and what we didn't want. Other software development firms jumped at us with marketing proposals, designers, and irrelevant business consulting. Hexagon IT Solutions took the time to understand who we are and offer us their services accordingly.

Thanks to Hexagon IT Solutions work, we have witnessed an enhanced performance in our software and received positive feedback from end customers.

Web Development Review from Mark Webster
Techforce working on the transition of our website name from Grande Exhibitions to Grande Experiences. The project involved the creation of a clone website where we could apply the new brand and update all content to reflect the name change before pointing the new and old domains at this new site. At the projects commencement, all details were scoped out and clarified to ensure that everything went according to plan. Through the entire project, Bhavin and the Techforce Team were professional,
Web Development Review from Fanny Gotschall
Bhavin is brilliant, and the project's success is largely because of his personal involvement.

While the client had a clear creative vision, Bhavin and his team at Techforce Global consistently executed it to perfection. For every scope change, Bhavin had the appropriate team and ensured all parties were aligned. (Verified via email)

Staff Augmentation Review from Sergey Novik
Were developing an internal image processing tool for our design team and needed two machine learning engineers, since our core developers were busy with other client projects. We required extra hands familiar with Python and computer vision, so after a developers market review, we hired them from SumatoSoft.The SumatoSoft developers joined our team and were able to swiftly adapt to our workflows, which resulted in them delivering the working models well before our hard deadline.Communication was straightforward throughout the engagement. We had video calls and exchanged brief text updates on a weekly basis. The delivered code is clean, and pull requests are well-documented.I appreciate that they pushed back on a few of our initial architecture ideas. They challenged our original approach and proposed a better method for handling the model weights. We plan to bring them back for the next phase of development.
Web Development Review from Domien Van Eynde
SumatoSoft is the firm to work with if you want to keep up to high standards. The professional workflows they stick to result in exceptional quality. Important, they help you think with the business logic of your application and they don’t blindly follow what you are saying. Which is super important. Overall, great skills, good communication, and happy with the results so far.
eCommerce Development Review from Alexander McCaig
The system has produced a significant competitive advantage in the industry thanks to SumatoSoft’s well-thought opinions. They shouldered the burden of constantly updating a project management tool with a high level of detail and were committed to producing the best possible solution.

Software Development Review from Daniel Rondell
We are notably satisfied with the upshot. PMs and development team was very devoted to the tasks and encouraging. We had a stringent and fixed deadline. And we got it just in time! KitRUM helped us to create an entire software that absolutely meets our requirement. They had presented the system in a short-term after putting their hands on it. They also provide support after developing this software. We have a different project now and certainly will work with KitRUM again.
Software Development Review from Adelina Romanova
KitRUM expanded our team to shift software to a new platform. Using JavaScript and RESTful APIs, they improved interfaces and DevOps, and fixed bugs. The team has always been on time. Their ability to understand the business requirements and their communication was just perfect. I definitely will recommend KitRUM as a reliable partner.
Software Development Review from Daisy Skot
KitRUM made a variety of development services: conception, coding, and QA, which means almost a full software package for our company. We needed to develop a few tasks, for example, a desktop app for our store, a cloud app for administration and supervision, and a portable app for end customers. However, we had an in-house team, which is not enough for this project. So we had to find a dedicated team that could deliver all we needed. We found KitRUM as a top-notch software development company

Software Development Review from Daria Stolyar
We hired Altoros engineers as an essential extension of our client-facing internal teams.

Ruby on Rails Review from Greg Lipper
In my 30 years in the software business, I have never had as positive an experience with an outsourced development services provider as I have with Altoros. Each Altoros engineer we have worked with has been strong technically, estimated development times accurately, completed projects on time, and delivered code and projects with high quality. Beyond that, they have helped improve our thinking and approach with suggestions and ideas that were better than the spec of instructions we supplied.

Software Development Review from Margaret N.
It was a pleasure working with Hivex. They quickly grasped the scope of our project and provided highly skilled developers within days. These engineers were efficient and integrated smoothly into our team. They built a robust remote work system that significantly improved our team's collaboration and productivity. The whole process was smooth, and the results were exactly what we needed.
Software Development Review from Olena Shabunina
We needed to quickly expand our dev team to build out a new feature set, and Hivex helped us find and bring on skilled remote developers to make that happen. The devs hit every deadline we set, sometimes even early. If we needed changes or had questions, they were super responsive - usually got back to us within a couple hours.
Software Development Review from Isammara Lourenço
We had a temporary gap in our technical team due to some transitions, and we needed to keep our development momentum going strong. Hivex provided us with skilled developers who seamlessly integrated into our team. They had the expertise we needed and filled the gap until we made permanent hires. Our collaboration with Hivex made sure our projects kept going without delay, we didn't lose our development momentum, and there wasn't any disruption. It was a huge help during a challenging time.

If I could leave 10 stars, I would! Working with 247Labs on our website was one of the best decisions we made. From day one, their communication was clear, consistent, and easy to follow. We always knew what was happening, what was next, and where input was needed.Their team was responsive, open to feedback, and quick to turn ideas into improvements. They didn’t just execute, they brought smart suggestions that made the final product far better than what we initially envisioned.On the technical and design side, they’re INCREDIBLE. Our site is fast, clean, modern, and built with real attention to detail. Every element was expertly crafted and feels unique to us.What stood out most was how supportive they were throughout the entire process. They were patient, proactive, and genuinely invested in getting the best result for us.Absolutely use 247Labs if you need a website. They deliver, and then they go beyond that!

Curious about another reviewer who looked older, a job applicant, who didn't have his call returned. Frogslayer slung cliche pablum his way. Apparently they hire Jr. Devs but do they hire over a certain age? Do they know the law? Their Senior Dev is under 30 and was hired from being a student employee. Curious and curiouser. Maybe Frogslayer isn't as woke as they appear. Friend of mine went through the ringer with them was told they'd get feedback either way. Instead they got the standard blow off rejection after devoting way too much time on a company that might not value "employees over a certain age." Heads up Frogslayer. There are laws.
