      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.

      Chop Dawg handled the UI/UX design for our upcoming mobile app and guided the project through a clear, organized process. We started by aligning on the scope, timeline, and expectations, then moved from low-fidelity layouts into detailed high-fidelity wireframes with refined copy and imagery. The team also helped us test the product and make final adjustments, resulting in a no-code demo we could use with investors, partners, and internal stakeholders. They were methodical, communicative, and even stayed ahead of deadlines.

      Due to past experiences, Latent AI is always cautious when hiring external engineering resources for a project. But collaborating with Admios is a breath of fresh air. The agencys account manager is nothing short of professional, attentive, and understanding of client needs. Furthermore, Admios seasoned and self-sufficient engineers fit seamlessly into the Latent AI culture. The team treats and trusts them as one of their own. (Verified via email)

      Off the Grid has had a longstanding developer partnership with Admios. Recently, the client trusted Admios with building a complex React Native POS system and a guest order-ahead app. Given the complexities of the project, Off the Grid wouldn't have chosen any other agency to work with. The Admios' developers did an excellent job, the management was proactive, and the software quality is exceptional. Admios is highly recommended. (Verified via email)

      For our project on food manufacturing, we hired Rushkar. This was made possible by the agency's outstanding support throughout the project, which included proactive problem-solving, innovative solutions, and meticulous attention to detail. At first, reaching a consensus on project objectives was the biggest obstacle, but Rushkar swiftly made plan adjustments and engaged in open communication to address problems. Our business was greatly enhanced by its solution, which also improved consumer involvement. Rushkar continues to be a reliable partner for our upcoming initiatives, even though it might further improve its excellent work with faster reaction times and more service options.
