ELEK+RIK Reviews & Testimonials

Web Development Review from Philip Wilson
ELEK+RIK team provided a streamlined process that was both simple and enjoyable. They kept to the budget and communicated well throughout the project. ELEK+RIK comes highly recommended and we would work with ELEK+RIK again if given the opportunity.

Mobile App Development Review from George McKerrow
ELEK+RIK has worked on improving our React Native mobile app. We had the skeleton of an app, but they were able to do an end-to-end re-design of each of the main pages. Since then, they`ve successfully implemented around ~20 different features on our mobile app. We share a spec and design, they provide an estimate and occasionally some design options, then when completed create a PR on GitHub. Their code is well-organized, easy to follow, and rarely do we have to go back-and-forth about bugs. They are also excellent communicators - carefully following threads on Slack, effectively communicating design and engineering tradeoffs, and even producing a 10m Loom video walking through a diagram. Their communication is top-notch. They are super easy to work with even though we are on very different time zones. And, I am impressed at the speed and execution of their development.

Web Development Review from John Riley
ELEK+RIK was tasked with creating a website for our company from scratch. They were professional, communicative, and dedicated to delivering an exceptional website that perfectly captured the essence of our company while exceeding our expectations. They are a talented, reliable, and customer-focused web design and development company that I would highly recommend to anyone.

Software Development Review from Nikita Vershinin
We've partnered with Sigma Software for almost three years, and they proved to be a strong partner with whom we'll keep working. Their adaptability and willingness to get things done are unique, settingthem apart from other providers. Moreover, they demonstrate a strong sense of ownership.

Software Development Review from Michael Meyer
We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

Mobile App Development Review from Esther Howard
The client is incredibly happy with Sigma's services and work. It has referred 3 other clients who also say how much they really love the team and process to get set up with the agency. Sigma is a fantastic company with excellent experienced professionals. Its experts care about quality and customer satisfaction, and they operate like the internal team's extension.

SoftDoes Reviews & Testimonials
Yuliia Ten's Review Sourced from Google
I started working with SoftDoes when our product had already grown beyond the point where small fixes were enough. We needed to rethink several parts of the system and make sure the next stage of growth would not create even more technical debt.The team got into the project fast. Within the first few weeks, they helped us identify the main bottlenecks, clean up several fragile integrations, and improve the parts of the platform that were slowing us down the most.One practical result was that a key operation that used to take around 4-5 minutes now takes less than a minute. I also saw a noticeable drop in recurring technical issues after the release.What I liked most was the way they worked with us. Very little ceremony, clear communication, good technical judgment, and a strong sense of ownership.I’d be happy to work with SoftDoes again on another complex software project.
Ryder Mackey's Review Sourced from Google
My experience with SoftDoes has been extremely disappointing. Their communication is terrible, the people I dealt with were highly unprofessional, and their pricing is absolutely outrageous compared to the value of the work being delivered.One of my biggest concerns is the company’s lack of transparency. From what I’ve observed, their development work appears to be outsourced to people in Ukraine through another company called Come Back Agency. Even when I searched for SoftDoes online, its website appeared to redirect to Come Back Agency.Take a look at their LinkedIn yourself. They present themselves as a Kansas City-based company, yet I couldn’t find a single employee listed as being based in Kansas City. That raises serious questions about their business structure, where their team actually operates, and who you’re really paying to develop your software.My interactions with the CEO, Orest, were particularly unpleasant. I found him extremely arrogant, dismissive, and condescending. He speaks to customers as though they’re beneath him. Rather than addressing legitimate concerns professionally, his attitude made an already frustrating experience even worse.Their Google reviews also raised serious red flags for me. Several reviewer profiles appeared to have AI-generated profile pictures, and the reviews themselves read as though they were written by ChatGPT rather than genuine customers. Many of these accounts had only ever reviewed SoftDoes.After I confronted them about these concerns, I noticed that some profile pictures had been changed to what appeared to be stock images, and the accounts had gained an additional review of random places. I cannot independently verify who operates these accounts, but the timing and patterns made me seriously question the authenticity of their online reputation.Nothing about my experience with SoftDoes has inspired trust. If you’re looking for custom software development, do yourself a favor and look elsewhere. Verify who you’re actually doing business with, who will be developing your software, and what you’re paying for.
Kevin Parker's Review Sourced from Google
We had been running a large part of our business through spreadsheets and a mix of different tools for years. We've grown past spreadsheets now. SoftDoes built a custom platform around the way our team actually works. That's probably what we appreciated most about working with them.

Trish Brown's Review Sourced from Google
My experience working with CouveCreative has been excellent. The full scope of our work together included a complete website redesign, a transition to new hosting, and ensuring an A level security scorecard...they handled each part with professionalism and attention to detail. Communication has been clear and consistent, and the team has been friendly, knowledgeable, and quick to respond to questions or changes throughout the project. I also appreciated their willingness to go above and beyond, even taking the initiative to learn and install a new tool simply to help troubleshoot an internal on premise issue on our side. We will be continuing our partnership with CouveCreative, and I feel secure and confident that any future needs or issues will be addressed with the same level of responsiveness and care. It has truly been a pleasure partnering with your company.

He’s highly collaborative, responsive, and genuinely invested in finding solutions that work for our business. His can-do attitude and adaptability have made a huge difference for us.We truly appreciate having a partner like Doron who is not only skilled, but also committed to growing alongside our business.
Andrew Pierce's Review Sourced from Google
Doron and his team are amazing! One of the things I spoke to Doron about when first meeting him was my desire to understand the overall structure of SEO better and I asked him if he would be willing to A. Start with a baseline of all the metrics of where our website currently was for future comparison and B. To explain to me in layman’s terms what he was doing when we met at the end of every month to discuss the results. He agreed with no hesitation and so far has been a huge help in increasing my understanding of SEO and also with huge results!Our company brand is very important to us and Doron has been very cognizant of that and has consistently tried to match the feel we are looking for in his website design and blogs.Doron and his team have almost tripled my website viewership in the span of six months, brought us to #1 on several search terms and in the top three for several others as well as increasing our google business clicks by over 300% in 5 months! Any minor technical issue that comes up he deals with swiftly and efficiently. I highly recommend him, he’s awesome!
