Sembit Reviews & Testimonials

AI Consulting Review from Bryan Beck
Shaun introduced us to some of the functions available in the ChatGPT Business plan. We discovered some very powerful tools that we will use in our lumber industry research and consulting work. Shaun was a great, knowledgeable tour guide and helped us get pointed in the right direction.

Web Development Review from Zach Gibbs
Sembit was fantastic to work with. They integrated our Zoho APIs and LIMS system seamlessly, and the dashboards they helped build have quickly become tools our teams use every day. The project went smoothly from start to finish, and the results have had a real impact on how we manage operations.

Software Development Review from Adam Kaufman
The team at Sembit and their work product has been nothing short of stellar. The team is a delight to work with. We have actively looked for more projects for them to work on because their deliverables are timely and of high quality. Sembit started out doing a mobile app project for us, then they grew to doing our Playground project for our effcc Compiler. They have also done a number of backend systems projects as well. The Sembit team are trusted advisors when we need to deploy a new system or work on a new project. Sembit will always be a go-to partner.

Event Management Review from Philip Cripe
During the Ethereum developers conference in Montenegro we organized an event together with Offchain and others. It was amazing, went really well. Would recommend working with Belkin Marketing for events in the future.

Event Marketing Review from Christian Dori
Working with Belkin Marketing has been a truly outstanding experience for Night&Day. From the very first interaction, Iaros and his team demonstrated a deep understanding of the music and entertainment industry, bringing strategic insight and genuine passion to every aspect of our collaboration. Their ability to connect us with the right people - from HNWI networks to key industry players - has been invaluable in expanding our reach and visibility. The team's responsiveness is exceptional; they are available around the clock and always ready to jump in with solutions, ideas, and support when needed. What sets Belkin Marketing apart is their "outside the box" mentality. They don't follow conventional marketing playbooks - they innovate, adapt, and consistently find new and effective ways to drive results. Their strategic advisory has helped us sharpen our positioning and approach major events with confidence. The quality of their work is top-tier, and the value they deliver far exceeds expectations. If you are in the music, entertainment, or Web3 space and looking for a partner who truly goes above and beyond, Belkin Marketing is the team to work with. Highly recommended.

Blockchain Review from MSc Nemanja Petrovic
Working with Belkin marketing is an ongoing experience. The most valuable thing about this partnership is their constant support and availability 24/7. We got high value leads, introductions and support during major events in our industry.

Web3 Development Review from Marián Čuprík
ORKA Systems did a great job for us. They delivered our website just as we wanted, and everything worked smoothly from start to finish. The team was easy to reach. Every time we had a question, they answered quickly and explained things clearly. We didnt waste time waiting for updates or chasing responses.Their technical work is solid. We asked for some custom solutions for our web3 development, and they handled even the tricky parts without any fuss. And they dont try to talk over your head with jargon. They keep things simple. The project cost was fair, with no hidden fees or surprise charges.We paid attention to the timeline, and ORKA delivered on schedule. The only delay we experienced was minor and well-communicated beforehand. I liked how the whole process was transparent. We always knew what was happening next.What stands out most is how willing they are to listen. If something was unclear, they fixed it fast. Our questions and suggestions were never ignored. Thats why I trust their team.In the end, our website looks good and runs reliably. It reflects what we wanted for our legal services business. If someone asked me to recommend a web development partner, I would mention ORKA without hesitation. No hype or big promisesjust honest work and good results.

IT Services Review from Jozef Semančík
Guys at ORKA systems helped my custom-bike building business not only by creating a very unique website for my company, but we are also using their own application (www.yeapp.app) for managing my business. Great cooperation - everything went perfectly!

Epic Apps Reviews & Testimonials
Jim G's Review Sourced from Google
As the owner of a commercial construction and maintenance company I have constant communication challenges…getting updates from the field, tracking materials, managing hours. It was eating up way too much time for everyone involved.We brought Epic Apps in to solve that, and they delivered on every front. They built us a custom private tablet app that our field crews use daily to order job materials, log hours, and submit job updates; and an internal website that doubles as an employee feedback hub, which has genuinely improved how we operate as a company.The whole team was professional and responsive from start to finish. If you're in the trades and looking for a development partner who actually gets your industry, Epic Apps is the real deal. I highly recommend them!Jim GagnonOwner – NorCal Construction & Maintenance Inc.
Elizabeth Stevens's Review Sourced from Google
After I had a false start with another developer, I found Epic Apps- they were ready to jump right in and were conscious of my budget. They made my dream come true of launching my own meditation app, Eyes Inward. Highly recommended!
TrustFall's Review Sourced from Google
I had an excellent experience working with this tech development company. They helped me create a unique app from scratch with creativity, collaboration, and thorough attention to detail. They truly understood my niche and provided a solid foundation I can expand on. Communication was professional and consistent throughout the process. I am very happy with the cost, service, and efficiency. The team's enthusiasm and commitment were also spot on, making the entire experience enjoyable and productive. Highly recommended! Truly, Epic!
