      Software Development Review from Dennis Temko

      Dreamers was the only firm capable of building my ambitious vision for HyperCite. They transformed an unprecedented concept into a patented, production-grade legal technology platform designed for fact-checking. This included help in product strategy, and leading UX, algorithm development, AI, database and cloud architecture, frontend and backend engineering, scalability, observability, CI/CD, deployment, and ongoing maintenance. They delivered two California product versions and a dedicated Arizona implementation integrated directly with the appellate court, where HyperCite has operated for more than five years. Today, HyperCite not only automates hyperlinks between legal briefs and cited records; its AI fact-checking system compares claims against supporting evidence, flags contradictions and unsupported assertions, and takes judges and attorneys directly to the underlying source. The result is faster, clearer, and more reliable judicial review, delivered through close collaboration with HyperCite’s leadership and the Arizona court CIO.

      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.

      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.
