      UI/UX Design Review from Yuriy Husev

      We hired DreamX to redesign our company website to better reflect DMTs modern approach to B2B lead generation and appointment-setting services. The DreamX team quickly understood our brands personality and transformed it into a sleek, fast, and conversion-focused digital experience. Their UX/UI team created user flows that made our content easier to navigate and optimized for lead capture. Communication was professional and consistent we always knew exactly what stage the project was in. The final result exceeded expectations: the new website not only strengthened our online presence but also positively impacted inbound lead quality. We highly recommend DreamX to any business looking for a creative and reliable design partner.

      UI/UX Design Review from Vlad Kozhulenko

      We worked with DreamX on developing a corporate website, and the results exceeded our expectations. Their team demonstrated a perfect balance of creativity, technical expertise, and attention to detail. From the very first step, they carefully analyzed our needs, created a modern and functional design, and ensured a smooth user experience. What impressed us most was their ability to translate our brand identity into a digital format that feels both professional and engaging. DreamXs communication was clear and proactive throughout the project, which made the entire collaboration smooth and efficient. I highly recommend DreamX to any company looking for a reliable partner in web and UI/UX design. They not only deliver on time but also go the extra mile to make sure the final product truly stands out.

      We partnered with DreamX to redesign our corporate website and improve its overall user experience. Their team approached the project with a clear strategy, focusing on both visual appeal and usability. From the very beginning, communication was excellent, every step of the process was transparent, and we received timely updates along with interactive design prototypes. DreamX demonstrated strong expertise in UX/UI, helping us simplify complex flows and create a design that looks modern, clean, and fully responsive. The final result exceeded expectations: the site now feels intuitive, fast, and visually consistent across all devices. Were very satisfied with the collaboration and highly recommend DreamX for any UX/UI design projects.

      Mobile App Development Review from DJA

      We paid $117,000 across two contracts $68,000 for development and $49,000 for marketing to Naked Development for a consumer-ready iOS and Android app and a full marketing funnel. They delivered neither. We originally requested delivery by Black Friday, the most critical sales window for a parent-focused consumer app. Naked Development proposed December as an alternative. That deadline was their own suggestion. They missed it. We extended to January, then February, then April, then issued a formal written Notice of Breach before giving them one final deadline the following June. Every deadline was missed. We were over 300% over timeline. When we finally handed the codebase to a second development firm, the app would not build on either iOS or Android. We paid thousands just to get it running enough to assess the damage. The contracted team was never fully assembled. Tickets were put on hold without explanation. Subscription management, the most critical feature of the app, was broken for months and never fixed by Naked. The commercial video Naked produced was unusable by launch, as cultural references had gone stale during the delay. We are software engineers who have led teams of over 100. These were not minor issues. They were basic, objective engineering failures. When we raised breach concerns with founder John Driscoll, his response was "let's just let our lawyers talk about it." We are aware of more than a dozen other former clients who experienced similar issues. Do not recommend.

      Mobile App Development Review from Mimi Bouchard

      I hired Naked Development in 2022 to build a new version of my mobile app. I paid $203,000 upfront (spread over six months essentially everything I had saved from my first year in business), and was told the app would be completed in five months, by Fall 2022. Instead, the project turned into nearly a year of delays, almost done updates, and declining involvement from their team. My very small internal team and I ended up doing much of the project management and QA work ourselves because progress had stalled so severely. Despite constant reassurances, no functional product was ever delivered. By mid-2023, I hired multiple external development teams to assess the code. Every single one independently concluded that the app was non-functional, unstable, not scalable, and could not be launched. They warned it would crash immediately and required a complete rebuild. I then hired a neutral third-party auditor with zero connection to any agency and his report confirmed the same findings. After paying over $200K, I had nothing usable. When I factored in delays, internal time lost, expert audits, and the cost of rebuilding from scratch, the financial impact to my business exceeded $500,000. After multiple attempts to resolve the situation privately were unsuccessful, I filed a lawsuit, which is now a matter of public record (Superhuman Inc. v. Naked Development). The case is set for trial in early 2026. While litigation is never something a founder hopes for, at a certain point it became the only responsible path given the evidence and the financial damage. I strongly recommend extreme caution when considering this agency.

      Mobile App Development Review from Jared Bossola

      Working with people that are as creative as I am is awesome. Receiving top marks across the board, Naked. is an innovative team of artists. The client praises them for their outside-the-box thinking and ability to connect on a creative level. Throughout the project, they’ve demonstrated attentive service and communication.

      Jessica Dally's Review Sourced from Google

      "We loved working with badpixel! We had already started talking with some potential locations and we needed to quickly establish our logo and branding. With the questionnaire that kicked off our discovery, we were able to capture what we were looking for and it was clearly understood as we went into our first review and really liked what we saw. After a few modifications, we had our logo and style guide allowing us to start working on our social presence while the badpixel team continued to work on our Square website setup. Once the site was ready, they walked us through everything and we were able to jump in and take control! Getting a website up just before the holiday season was huge, it lead to our first sales and profit!"
