"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."

Paul S. Chun

Rivalfox GmbH

"The Rivalfox had the pleasure to work with SumatoSoft in building out core portions of our product, and the results really couldn’t have been better.

SumatoSoft supercharged our productivity by providing us with three team members whose technological expertise was surpassed only by their enthusiasm. Many times they found better solutions than were given to them, and with that alongside their excellent ability to communication, they made our product better, faster, which resulted in customers becoming happier sooner. SumatoSoft provided us with engineering expertise, enthusiasm and great people that were focused on creating quality features quickly."

"SumatoSoft succeeded in building a more manageable solution that is much easier to maintain.

Although they are a small team, their project management reflects the excellence of a larger company. Their team delivers high-quality results, attentive service, and reasonable pricing."

Damian Gevertz

Founder & CEO

"We tried another company that one of our partners had used but they didn’t work out. I feel that SumatoSoft does a better investigation of what we’re asking for. They tell us how they plan to do a task and ask if that works for us. We chose them because their method worked with us."

I was impressed by SumatoSoft’s prices, especially for the project I wanted to do and in comparison to the quotes I received from a lot of other companies.

Also, their communication skills were great; it never felt like a long-distance project. It felt like SumatoSoft was working next door because their project manager was always keeping me updated. Initially, I was afraid of going with an overseas company because they don't have to abide by US law, but I had a good project manager who made it seem like they weren’t an overseas company.

"SumatoSoft developed a new version of the MyMediAds service. When we turned to the SumatoSoft experts, we had already been using an MVP version, which we would like to improve.

Together with the team, we have turned the MVP version of the service into a modern full-featured platform for online marketers. We are very satisfied with the work the SumatoSoft team has performed, and we would like to highlight the high level of technical expertise, coherence and efficiency of communication and flexibility in work.

We can say with confidence that SumatoSoft has realized all our ideas into practice. In the future, we plan to continue working with SumatoSoft on improvements of the MyMediAds service. We will highly recommend SumatoSoft to those who want to successfully plan and implement a truly quality project."

"We are absolutely convinced that cooperation between companies is only successful when based on effective teamwork (and Captain Obvious is on our side!). But the teams may vary on the degree of their cohesion.

With SumatoSoft LLC, we feel like a bobsled team - together in the same cockpit, aimed at the same targets. And this feeling is off the chart.

We are sure that by aligning our efforts we will set new records and grab new medals."

"SumatoSoft was chosen to replace our previous development team and to work on relaunching our freight forwarding logistics web-service after careful research and several conversations.

From the start and throughout the project, all communications and project management were very professional and the quality of code was very good and consistent. SumatoSoft team managed to improve the existing service architecture, add important features to our new site and warehouse management system and quickly respond to troubleshooting requests related to both the older and the newly launched versions of our service.

Thanks to SumatoSoft can-do attitude, amazing work ethic and willingness to tackle client’s problems as their own, they’ve become an integral part of our team. We’ve been truly impressed with their professionalism and performance and continue to work with a team on developing new applications.

We would definitely recommend SumatoSoft as a reliable technology partner for demanding development web projects."

Michael Karbushev

Senior Director of Engineering

"They are very sharp and have a high-quality team. I expect quality from people, and they have the kind of team I can work with. They were upfront about everything that needed to be done.

I appreciated that the cost of the project turned out to be smaller than what we expected because they made some very good suggestions. They are very pleasant to work with."

Pratasevich Ivan

Chief Executive Officer
Ivanco-Media LLC

"We’d like to thank SumatoSoft for the exceptional technical services provided for our business. It should be noted that we started our project’s development with another team, but the communication and the development process in general were not transparent and on schedule. It resulted in a low-quality final product.

That’s why we were looking for a team, which would know how to be clear in their proposal, to be responsive to changes and to be on track of the schedule. SumatoSoft professionals met all the requirements we had. They managed to fix all the mistakes made by the previous team and to deliver the web solution of the highest quality within budget.

Creativity and excellent tech expertise of the team in combination with the transparency of working process make SumatoSoft the best company to work with."

Andrey Kubka

Product Technology Manager

"Nectarin LLC aimed to develop a complex Ruby on Rails-based platform, which would be closely integrated with such systems as Google AdWords, Yandex Direct and Google Analytics.

We were looking for a professional outsourcing company to extend our in-house team and help us to solve difficult technical problems.

We hold a large-scale tender to select a partner. Even at the tender stage, SumatoSoft team showed a desire to go deep into our project and suggested an architectural solution we liked. Other bidders, including top Moscow Ruby on Rails agencies, showed much less interest, sending formal business proposals with prices for their services. Therefore, we started to work with SumatoSoft.

SumatoSoft team not only knew well how to build a partnership-based working process, but also offered sensible suggestions and advice helping us to reach the long-term business goals.
We are completely satisfied with the results of our cooperation and will be happy to recommend SumatoSoft as a reliable and competent partner for development of web-based solutions."

Sumatosoft is great in every regard including costs, professionalism, transparency, and willingness to guide. I think they were great advisors early on when we weren't ready with a fully fleshed idea that could go to market. They know the business and startup scene as well globally.

They did a great job hitting cost estimates and are a bargain for quality. They also helped our business concept greatly. We are confident in our plan and future in the hands of SumatoSoft.
