Kevych Solutions Reviews & Testimonials
Vasco Rouw Founder at Mavelli
5.0★
Mobile App Development Review from Vasco Rouw
Weve been working with Kevych Solutions full-time for over a year, and the experience has been excellent. They handle the complete end-to-end development of our AI-powered mobile apps, including UI/UX, frontend and backend development, AI integrations, infrastructure, deployment, and ongoing support.What stands out most is the extremely high level of their technical expertise and execution quality. They actively use AI and modern development workflows to maximize efficiency and deliver results quickly. The team is highly responsive, proactive, and always goes the extra mile to meet deadlines.Since working together, we scaled from 0 to over 100,000 subscribers in just 8 months, and our apps are now generating more than $1M in monthly revenue. Whenever challenges came up, we solved them together efficiently, and Kevych Solutions continuously adapted and grew alongside our projects.We highly recommend them to anyone looking for a reliable, high-level mobile app development partner.

ELEK+RIK Reviews & Testimonials
Philip Wilson Managing Director at Premier Automation Ltd

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.
George McKerrow CEO at Ted's Montana Grill
5.0★
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.
John Riley Executive Vice President at MediaCentric

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 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!

Web Development Review from Sofia Juan
We recently had the pleasure of working with Small Projects Bureau Development on our new website for Show Kids, a company offering performing arts classes and after school programs for children in NYC. From start to finish, the experience was amazing.The team at Small Projects Bureau Development truly understood our vision and was able to bring it to life in a way that exceeded our expectations. Their creativity, attention to detail, and technical expertise resulted in a beautifully designed, user-friendly website that perfectly reflects the essence of Show Kids. The website is not only visually appealing but also functional and easy to navigate, which is crucial for our audience of parents.Throughout the process, they were communicative, responsive, and highly professional. They took the time to understand our specific needs and ensured that every element, from the layout to the content, was aligned with our goals. The final product showcases their commitment to quality and their deep understanding of web development.We couldnt be happier with the outcome, and were excited to share our new online presence with our community in NYC. So much so that we are now working with Small Projects Bureau Development again to create a new website for our upcoming location in Barcelona, Spain. If you're looking for a team that combines creativity with technical skill, we highly recommend Small Projects Bureau Development!Thank you for helping us bring Show Kids to life online, both in NYC and soon in Barcelona!

Daniel Pope Review from Google

Daniel Pope's Review Sourced from Google
Honestly, I didn't expect to be this impressed. Atomic Actions leveled up our processes and freed up a ton of our time. Before them, we were drowning in manual client onboarding and endless content creation - my team was spending a ton of time and energy on routine tasks that slowed us down and even worse...did nothing to actually help us grow.These guys came in, understood our pain points, and built out systems that blew our expectations out of the water. Now, with their AI-powered content agent, we can pump out all sorts of marketing assets in minutes, not days. Our strategists finally can focus on creative work instead of copying the same old emails and docs.And the best part? It all just runs quietly in the background, organizing everything and saving it right where it needs to be.On the onboarding side, Atomic Actions automated our whole process: from the client's first form to setting up everything in our CRM and other tools. What used to take us days (and no joke, a LOT of headaches) now clicks by in 10–15 minutes.Since implementation:- We onboard clients 95% faster- Create content 92% faster- Have 400% increase in client capacity without new hires- Freed up 40+ hours/month for the team,- And can save $18k/year by replacing manual laborThe team at Atomic Actions actually cares about the end result (a rarity, seriously).If you’re looking to free up your time, scale your operations, and take some serious stress off your plate — I can’t recommend Atomic Actions enough. Worth every penny!
