Chop Dawg Reviews & Testimonials

Web Development Review from Jimmy Caldwell
Chop Dawg was the strongest development team I’ve worked with in 18 years of software implementation. They took our complex AI-powered senior placement platform and turned it into a functional marketplace with dashboards, business rules, CRM integration, and an AI assistant. The team listened, adapted, communicated often, and treated our vision with real care. The handoff had a few gaps, but overall, they delivered exceptional work.

Design Services Review from Nathan May
Chop Dawg delivered wireframes, high-fidelity screens, a logo, and Figma files while keeping each week’s work clear. They felt like part of our team, brought fresh ideas, and pushed back when needed. The experience was strong overall, though a more detailed final review would have been helpful.

Web Design Review from Anonymous
Chop Dawg turned our early idea for a visual polling and decision-making platform into a prototype we could confidently share with others. It made the product much easier to explain, gave us something real to test with users, and supported more productive investor conversations. The work also helped our team get aligned on the product direction, development scope, and MVP roadmap. Their team was responsive, organized, and easy to work with throughout the process.

Sigma Software Reviews & Testimonials

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.

Alegnta Yimam's Review Sourced from Google
Definitely recommend! Integrated has been our most reliable partner for the last five years. They designed and deployed our dispatching software from scratch, followed up, and addressed all the concerns we had. They are also handling our marketing and providing all other IT support we need. Bryan is very well-rounded and trustworthy! I wanted to give them a sixth star... but Google came up short.
Lauren Bo's Review Sourced from Google
I would truly recommend utilizing Integrated IT solutions. The database that they have created for my business has done wonders. The team is always ready to help whenever I reach out and guides me step by step on how to resolve any issue that may occur. I would definitely recommend!

Integrated IT solutions have exceeded every hope and expectation! In partnering with them to create a Web platform for my agency's 25 employees to use, not only has my workload and stress been reduced, but the platform has received raves from my employees, who love using it! I can now dedicate more time and energy towards increased growth of my agency instead of tedious paperwork. Thank you to Bryan and the whole team, they never disappoint!
