      Mobile App Development Review from Andrew Duggan

      Kanda proved to be an exceptional choice for our development needs. They were much more [of] a partner to our startup than a vendor. The entire team treated our project like it was their own company, and the results showed that. Our customers were extremely please[d] with the desktop and mobile applications. I would definitely recommend hiring Kanda for any and all of your development needs. (Verified via email)

Overall, we are very happy with Kanda's team! (Verified via email)

      The team at Isadora Agency is phenomenal to work with. They listened to our needs, addressed any questions quickly yet thoroughly, and made great recommendations throughout each phase of the project. They are incredibly transparent, responsive, and organized, which kept all deliverables of the project on-time and within budget. We felt the success of our project was a top priority for the team at Isadora Agency, which was woven throughout every deliverable.

      I have worked with Isadora Digital Agency across multiple projects including a full website redesign to providing ongoing support to for various digital projects. In each capacity I have found the entire team to be responsive, collaborative, and professional. They come prepared with new ideas and are always willing to try to find ways to advance our digital needs. I highly recommend.

      Roberto Aponte's Review Sourced from Google

      I am thoroughly pleased with your companies ability to deliver an exceptional working relationship that has lead to an eloquently executed client experience. Isadora Digital Agency took a much-needed concierge approach to our relationship and helped us define our goals as well as align the expectations of the officers of our company. Our needs and vision were sophisticated but you helped us to achieve our vision through a multitude of legal and compliance challenges while still creating a warm and textured environment for our clients to engage with us. There have been multiple occasions the agency has gone exceptionally above and beyond to make this project a success – had we partnered with some of the other 9 design companies we were engaged with, I don’t feel confident that they would have provided the white glove service that we received from your firm. Let me summarize: Isadora delivers enterprise style service and results with the client engagement and human interaction of a boutique firm.
