      Mobile App Development Review from Mica Palmer

      They helped us solve issues. They designed an app for us.High level/quality of client attention and interaction. All communications, information exchages, and client servicing were well-conceived and well-executed. They kept me on my toes to provide them the information they needed from me. They kept excited about the project and, because of that, kept me optimistic and driving toward the success of my project. The culture of coaching and support they provide start-ups. They don't sleep well unless they know you have all the tools and chops to obtain success. I've never seen any other company provide such rich and valuable deliverables along with ingenious and compassionate client support. Kodevent is a beacon of know-how and wisdom in an otherwise dark ocean for any start-up that is hoping for success.

      eCommerce Development Review from Devul Nahar

      We needed help designing the Frontend pages on my website. Also some design work. Everyday I would assign my Frontend developer some key tasks and deliverables. He would report back to me. An example of key deliverable he did was help design the logic of flow of grading when we have multiple types of questions. They were quick to respond and professional. They had great professionalism, good talent, and good support.

      Web Development Review from Peter Wallace

      Kodevent and their team were always great at communicating with our team. They worked very hard to finish tasks in the allotted time frame. When we had requests or changes, they were always quick to find a superior solution. Our project is still ongoing, but they are waiting on our side of things to complete and go live. I am appreciative of their great communication skills. They were always quick to respond and worked within our time frame.

      Web Design Review from Patrice Archer

      They developed a SaaS web platform with smart scheduling and automation tools for us at and built the platform's front- and backend and integrated a custom analytics dashboard and calendar integrations. But to be honest what impressed us most was how deeply they engaged with our vision. They didn't just write code they challenged assumptions, proposed better workflows, and contributed as if they were part of our internal product team. Their ability to think strategically and focus on user experience made them feel more like tech partners than a typical outsourced vendor.

      Startups Software Development Review from Justin Collins

      Our first engagement with Twenty Ideas was accurately scoped and allocated from day one, and that was impressive. Being on time and budget while exceeding expectations seems impossible for many vendors, but with Twenty Ideas, there were zero issues. They anticipated our needs and presented clear options when necessary.

      Mobile App Development Review from Rachel Efron

      The most impressive thing was the collaboration we established. I had been creating this app by myself for so long, and all of a sudden, I had a whole team of thought partners. Twenty Ideas really got in there with me, learned what I was trying to make, and collaborated with me on it. It was an extremely rewarding experience, and we're thrilled with the app!

      I started working with Twenty Ideas in a part-time consulting capacity, but I became so taken with the team’s passion, mission, and supportive culture, that I ended up applying for a full-time position. I’ve been with the team for three and a half years now, and it’s given opened doors to expand my skill set; work with smart, kind, and dedicated people, every day; and work with clients who truly care about making a positive impact, to create life-changing solutions together. It’s a great place to work!

      Bryan Pratt's Review Sourced from Google

      Mystic Media has been excellent to work with, offered great value, and their expertise and project management has been evident throughout the development process. We hired Mystic to take an idea and concept drawings through UI/UX and graphic design, programming and development, all the way to the market. They have met or exceeded all milestones, even with significant additions to scope along the way. We're currently in beta testing before release, and we are very satisfied with the entire experience. Mystic has earned my unqualified endorsement for anyone looking to develop their first app with them, as we have done.

      Igor Caleta-Car's Review Sourced from Google

      I worked at Decode for about a year, and during that time I had the chance to meet many wonderful colleagues who helped me grow professionally and learn new skills. Because of the nature of my role, I also had the chance to collaborate with clients across Europe, the USA, and the Middle East, and even visit some of them in person. The team I worked with was everything you could hope for - driven, proactive, and always willing to jump in and help. The development teams I was part of were well-balanced in both skills and personalities, led by highly experienced engineers who lead by example. Beyond the projects themselves, the company culture stands out. People are friendly, and the leadership is focused on sustainable growth while supporting employees development. Decode isn’t afraid to promote talent and encourage people to step outside their comfort zones in order to grow. The office is also in one of the best business neighborhoods in Croatia, with plenty of variety for employees nearby. Overall, I highly recommend Decode as a great place to work!

      Working with DECODE has been a great experience so far! Their team is skilled, flexible, and always open to collaboration, which makes the process smooth and enjoyable. Their modern design approach aligns well with our vision, and they show a real commitment to delivering a strong final product. What we particularly appreciate is their willingness to engage and adapt as the project evolves. While some aspects require additional clarification along the way, they are always receptive to feedback and ready to adjust accordingly. The overall working atmosphere is positive and professional, making them a great partner to work with. Looking forward to the second half of our project!
