As a thriving healthcare company, we teamed up with the awesome folks at Buttercups for some serious React.js magic, and boy, did they deliver! From the get-go, their team was all about communication, making sure they got our vision and addressed any concerns we had along the way.Not only did they nail our project within the deadline, but their meticulous attention to detail really blew us away. The best part? They totally get the unique challenges of the healthcare industry, so they tailored their solutions to fit our needs like a glove. No cookie-cutter stuff here!Their commitment to ongoing support and maintenance gives us the peace of mind we need in this fast-paced industry. Long story short, if you're a healthcare organization looking for top-notch React.js services that actually understand your world, look no further than Buttercups. These guys rock!

Web Development Review from Olga Valodze
ScaleMeUp built a complete website for our company, with each page designed as a standalone landing page optimized for mobile, conversion-focused, and tailored specifically to the U.S. market. They also helped us improve overall conversion rates and integrated the site with key third-party tools to support our operations.In addition to the website, ScaleMeUp developed a multi-role iOS app that continues to evolve. Thanks to this solution, we are now able to effectively track our employees work and have fully automated our payroll process saving time and significantly reducing administrative overhead.Throughout the project, we've also worked together on optimizing user flows and integrating new features that support our business goals.We are satisfied with our collaboration with ScaleMeUp. There were challenging moments, as in any complex project, but we always managed to find a compromise and continue working together successfully to this day. I can confidently recommend ScaleMeUp as a reliable and proven partner, capable of solving even the most demanding technical and business challenges.

Anders Östlund Founder at Reppa AB

Web Development Review from Anders Östlund
CleverCrew is great to work with. I have known the company for four years now and worked together for a year and a half. My favorite is that you can tell them to fix anything, and they will. Not these closed boxes with specialities that have become common among certain developers but instead open minds and a "fix-it, and make it work" attitude.
Brigitte Granger Founder at Supporti, LLC

Mobile App Development Review from Brigitte Granger
CleverCrew was recommended to me by a fellow entrepreneur, and I'm so glad I took their advice. Over the course of building my startup, I worked with at least 10 other developers and agencies, but none came close to the professionalism, experience, skill, and friendliness that CleverCrew brought to the table.The lead developer Tonya was outstanding. She balanced understanding our needs with offering thoughtful recommendations to improve the project. Her communication was excellent, and despite major time zone differences, she ensured we were always aligned and informed at every stage. She also demonstrated strong leadership, managing her team with precision and proactively addressing any issues or questions.We ultimately had to make the difficult decision to shut down company. However, having CleverCrew by our side during this challenging time made the process far less painful. Tonya's support and guidance throughout the closure were invaluable, ensuring everything was wrapped up professionally and efficiently.For anyone looking for a reliable, skilled, and collaborative software development partner - especially a bootstrapped startup - I couldn't recommend CleverCrew more. They set the bar for what a development team should be, and I'm grateful for their role in both building and gracefully guiding me through the closure of our mobile app project. I look forward to working with them again in the future!
