      Web Design Review from Rachel Nguyen

      After the first time partnered with Sota Tek, which was totally beyond my expectations and generated great results, Sota Tek has become our trusted agency for many later IT projects. This dedicated team of professional engineers has proved to have in-depth experiences in both blockchains and building scalable technical solutions. When working with Sota Tek, timing and efficiency were never my concerns as they were always ahead of the schedules with all the tasks. Moreover, any requested change f

      Samzzy Ayomide's Review Sourced from Google

      Unfortunately, my experience working with [SOTATEK GOLBAL] was not positive. While I always aim to deliver high-quality work, the project faced challenges due to unclear requirements, delayed feedback, and lack of timely communication. This made it very difficult to stay aligned on expectations and meet deadlines.Additionally, payment terms were not handled as agreed, which created unnecessary stress and delays on my side. As a freelancer, I value transparency, respect, and collaboration and I felt these aspects were missing in this engagement

      Mobile App Development Review from Dr. Lesley Kirkpatrick, MD

      I had a great experience working with Tepia. Abraham, the Founder and CEO, was available, helpful, and actively involved throughout every stage of the process. Kimmy, my assigned project manager, was organized, responsive, and clear in her communication from start to finish.They anticipated potential obstacles before they became issues and approached everything with a thoughtful, solutions-oriented mindset. The team was consistently proactive, professional, and transparent. I truly appreciated their structure and ability to keep things moving smoothly. I would highly recommend working with Tepia.

      Mobile App Development Review from Robert Beknazarian

      Working with Tepia Co has been an exceptional experience from start to finish. They played a critical role in developing our mobile app for RELI, and I can confidently say they exceeded our expectations on every levelFrom day one, Tepia demonstrated a deep understanding of both the technical and business sides of app development. They didnt just execute tasks they asked the right questions, challenged assumptions when needed, and helped us think through complex workflows in a way that improved the final product. Their team truly operates as a strategic partner, not just a development vendor The communication was excellent throughout the entire process. We always knew where things stood, timelines were clear, and any issues or changes were handled proactively and transparently. For a project as complex as ours involving pricing logic, user flows, financing options, compliance considerations, and scalability this level of clarity and responsiveness made a huge difference.What really stood out was Tepias attention to detail and commitment to quality. The app they helped build is stable, clean, intuitive, and built with long-term growth in mind. They were thoughtful about architecture, performance, and future enhancements, which is critical for a company like ours that plans to scale aggressively.They were also extremely flexible and patient as our requirements evolved (which happens in real-world startups). Instead of pushing back, they collaborated with us to find smart, efficient solutions that aligned with our vision and budget.If youre a founder or business owner looking for a team that:Truly understands mobile app developmentCommunicates clearly and consistentlyThinks strategically, not just technicallyDelivers high-quality, scalable workI highly recommend Tepia Co without hesitation. They have been a trusted partner in bringing RELI to life, and we look forward to continuing to work with them as we grow

      They delivery excellent results on the backs of hardworking vendors... which in turn, they do not pay. From a business ethics standpoint, it's worth looking into another agency who cares about their subs.
