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

Mobile App Development Review from Ara Agopian

Mobile App Development Review from Makaila Malungahu
Working with Chris and Mystic Media was the best decision. They designed and built our peer-to-peer wedding and event rentals app from scratch, and it looks and works great! We're super happy with our project!
Makaila Malungahu's Review Sourced from Google
Working with Chris and Mystic Media has been great for our huge app development project and excited to continue working with them. Don't hesitate to reach out to them!
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.

INC4 Reviews & Testimonials

Software Development Review from Liudmyla Osadcha
From wireframes to production release, INC4 built all of our user-facing products. The initial concept validation, design, and prototyping was created by our organization, but INC4 helped us to refine our interfaces and ensure the application logic was solid. As a result, we have collectively built and released four interconnected user-facing software applications that all are integrated with blockchain technology.This suite of applications is integral to our business. INC4 made our software products world-class in terms of usability, functionality, and reliability. Working with INC4 ensured our products were built and released on time and on budget.INC4 has a multitude of world-class project managers that make our work easy and fun. The project manager's excellence in communication, technical mastery, and expectation management ensure our project's delivery is of minimal concern. Delivery roadmaps are always communicated clearly and met without fail. The only time deadlines shift are when we (the clients) introduce new development criteria or features that take more time to build. However, even when this happens, the INC4 team are unflinchingly eager to accommodate our changes and adjust delivery processes accordingly. INC4 is efficient, agile, and thorough.The most impressive aspect of INC4 is how they seek to become truly invested in the development and success of each project they work on. They go beyond what is typically expected in this relationship, and are true partners who want to see our company grow. This provides a deep sense of security and trust for us as their clients.We never have to even consider INC4 taking shortcuts during the development journey because that kind of behavior is so opposed to their core organizational ethics. No matter what obstacles this organization faces, they adjust their development capacity accordingly and keep working with consistency & happy attitudes.

Veronica's Review Sourced from Google
I agree with the other review. This company claims that they can build websites and that they are located in Modesto, California which is not true. I have been calling them for weeks and so far no response. When I told them that I wanted a refund, they quiclky put some items on the website. They are very dishonest
Aristides's Review Sourced from Google
Been waiting for my refund I’m happy to see that you don’t really care for clients. Anyone looking to work with you will disappointed and the quality of humans you are thanks for understanding. Thanks for replying to all my emails and text messages. I’ll make sure everybody knows.
