      Probey Services has truly developed and presented my presence as an artist. They created a stunning portfolio and website that beautifully showcases my music, albums, and artistic journey. The branding and logo design were crafted with precision, giving my identity a strong and memorable touch. Other than that I have outsourced my Social Media to them for a year, and their social media marketing strategies have expanded my reach, allowing me to connect with my audience more effectively. The team is professional, responsive, and exceptionally creative, making the entire process smooth and enjoyable. I surely recommend Probey Services to any artist, business or any brand looking to make an impact online. May this project and review bring you all the growth and recognition you deserve.I have attached the required photography as per your specifications. Wishing you and your team great success. Hope you achieve all your goals.Thanks again for your outstanding work. I look forward to future collaborations.

      Mobile App Development Review from Amanda Chalofsky

      My experience with Simpalm was very good. They made a full prototype of our neuro-wellness app so we could show partners and investors what our system looks like. It matched our brand and showed the flow in a simple way. Their communication was steady, they stayed on time, and they explained things clearly. The prototype helped people understand our idea fast, and it moved our project forward. I felt supported the whole time.

      Mobile App Development Review from Matt Rudnick

      Working with Simpalm has been a really positive experience. We hired them to handle the frontend development of our mobile app for iOS and Android, while our backend was already in place. From the start, their team communicated clearly, stayed organized, and met every deadline we set. They were flexible when we added new features, and their designer’s input really helped improve the look and usability of the app. I appreciated how reliable and easy they were to work with having a U.S.-based team made communication smooth and fast.

      Web Design Review from Steve Dickson

      Simpalm partnered with us to redesign, develop, and deploy our corporate website, providing strong value and creativity throughout the process. Their design phase was particularly impressiveusing Figma, they collaborated closely with us, provided creative infographics and visual assets, and delivered polished branding and wireframes that aligned with our goals. This allowed us to confidently defer much of the creative direction to them while still having opportunities to review, provide input, and iterate over alternatives.Project management was handled through a dedicated project manager, with virtual meetings and a collaborative project site keeping communication organized. From the outset, we agreed that achieving a high-quality design was more important than strict timelines, and Simpalm supported that approach. The design phase was timely and well-executed, and overall, they remained responsive and delivered the key milestones.Most importantly, the website is now fully deployed in production and reflects the design sessions and specifications we set. The end result is a responsive, user-friendly site that enhances our branding and capabilities. What impressed us most was the value Simpalm delivered: strong design and creativity, great collaboration, and a willingness to bring forward ideas while working with us to refine the final product.

      Mobile App Development Review from Angela Odden

      Partnering with ChopDawg was hands down one of the smartest moves I've made. From day one, Joshua and Leo Lopez treated my idea with the kind of care and creativity you dream of finding in a development team. What started as a simple concept quickly became something visually stunning beyond anything I imagined.They never made me feel like just another client. Every question we had big or small was met with patience and insight. Their feedback was always honest, their communication consistent, and their commitment unwavering. Weekly Zooms were productive and on point, and their follow through was exceptional. It's clear they don't just build products, they build relationships. And were so grateful for that.

      Mobile App Development Review from Jeff Gillis

      Chop Dawg did an amazing job on not only my app design, but my overall business plan when I hired them. Being a novice in the app world and coding world, they helped me understand what my business plan and app needed to be successful. When it is your baby, you get overprotective and think you are right, but they say when starting a business always surround yourself with experts in the field you are entering, because you are no expert. Chop Dawg and CEO Joshua are experts. They know how design a beautiful app and make sure it is competitive in the marketplace and show you all the intricacies of development to launch. They are great at what they do...just look at their apps! They walk you through the whole process, hold your hand and make sure you are happy with the final product. Any problems that do arise, they are always available and work side by side with you. Not only is your app your baby / business, but it is Chop Dawgs as well!

    • Terry Heller
      Terry Heller CEO at Preferred Roofing
      5.0
      Web Development Review from Terry Heller

      As a growing roofing company, we knew our old website wasn't doing justice to the kind of work we do at Preferred Roofing. It looked outdated, was hard to navigate, and didn't reflect the level of professionalism we bring to our projects. We wanted to change that. Our main goals were to create a new website that would clearly show our services, build trust with new visitors, and make it easier for people to contact us or request quotes online. We also wanted the site to work well on mobile phones because a lot of our customers use their phones to search for roofing services.So, we hired JanBask Digital Design to completely redesign and develop our website. We were looking for a partner who would not only build us a great-looking site but also guide us through the process and make sure the site helped us grow our business.They asked detailed questions about our services, customer base, and how we wanted people to feel when they visited the site.Scope of the work included:Designing a responsive website from scratchCreating unique pages for all our services (roof repairs, installations, gutter services, etc.)Adding a clean, easy-to-use contact form and quote request systemThe new website has made a real difference for us. We've received more calls and quote requests since the launch, and customers often mention how easy it was to find what they were looking for on our site. The new layout makes our services very clear, and the site feels clean, modern, and professional which is exactly what we wanted. It has definitely helped us build more trust with new visitors.Project management was excellent. JanBask kept everything organized and walked us through each step. They gave us regular updatesWhat stood out the most was their care and attention to detail. They didnt just build a pretty website they made sure it worked for our business. They didnt rush the process either they truly wanted us to be happy with the final product.

      Web Development Review from Jason Anish

      When we approached JanBask Digital Design, our companyAustin Financial Services, Inc.was going through a critical branding transition. While weve been around for over 40 years and have built a solid reputation in asset-based lending, our online presence didnt reflect the trust, speed, and flexibility we offer to our clients. We needed more than just a website redesignwe needed a digital experience that could communicate our value, streamline how potential clients learn about our services, and ultimately drive real business conversations.We specifically hired JanBask to help us accomplish a few main goals:Modernize our websites look and feel without losing the credibility and seriousness expected of a financial company.Improve the user journey for business owners and financial decision-makers who are looking for fast, flexible credit solutions.Create a strong foundation for future digital marketing efforts like SEO, paid ads, and client onboarding automation.Make the site mobile-friendly and easy to navigate, especially for busy executives browsing on the go.We had tried updating our site with internal resources and freelancers before, but it never really hit the mark. So we were cautious going inbut hopeful.JanBask started the project with a series of discovery calls where they really took the time to understand not just what we do, but why we do it and who we do it for. They dug into our client personas, our lending process, and even how our sales team follows up on leads. It felt like they werent just designing a websitethey were building a tool tailored to how we actually work.What stood out most to us was their ability to translate financial language into something both clear and client-friendly. Were used to dealing in technical lending terms, but JanBask found a way to keep things professional and easy to understand. Thats not easy to pull off.
