      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.

      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!

      I approached the Solvingo team without a specific idea. During our consultation, they presented several design options, from which my website was tailored to my individual needs. They also suggested design elements that would further enhance my site. I thank them very much for their fast and beautiful work, it exceeded all my expectations!

      Ritu M's Review Sourced from Google

      The worst company and the owner "Rahul" that we have come across in our life. Don't even feel like giving a single star. First he would quote you a lower price , and do lots of errors on your website, then would ask you for more money to correct those errors and would drag it further for 2-3weeks than the said time. Would never give you updates unless you ask for . No time limit for work completion. Very unprofessional and rude and has the audacity to ask for payment without even completing half of the work and if you don't pay him he locks your half done website from his end and doesn't give you access to your website and asks you to pay . Even if you put a review on his website, which we did as we didn't like his work he was furious and asked us to remove it else he would stop access to our website. That also means that all these good reviews here are "fake". Now finally when we are in the last stages of website completion which was supposed to be done 2 months back, he against asked us to make payment saying only then he would complete the work and we refused. So he again tried to bring down the website and tried to hack in the hosting that we bought for our website. We and our business have been suffering a lot because of this guy since March this year. Writing this review, so that no one else suffers because of such unprofessional people and we are definitely taking legal action against him and the company. Also he has a fake U.S. address and phone number on his website which we confirmed by calling and contacting the person in U.S. Also this.person has been lying to us constantly that he is working in a govt . office on a govt. project for sometime and told us he was busy from 9am to 9pm mon-fri which as it is left no time for our project. Whereas he is working as a Project Manager with Purelogics Rohini since April this year which was after he started our project. Please check his Linked In profile. BEWARE!!
