      Kanda proved to be an exceptional choice for our development needs. They were much more [of] a partner to our startup than a vendor. The entire team treated our project like it was their own company, and the results showed that. Our customers were extremely please[d] with the desktop and mobile applications. I would definitely recommend hiring Kanda for any and all of your development needs. (Verified via email)

      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 level From 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 development Communicates clearly and consistently Thinks strategically, not just technically Delivers high-quality, scalable work I 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

      denny stearns's Review Sourced from Google

      I bought the Carmela the other day. It is smoky, with burnt Carmel, marshmallow taste and smell. This is not my type of whiskey. I like smoke but there was something that disagreed with me. So this line is not my cup of... whiskey. Looking forward to trying their Bourbon and will update my tasting experience. The R6 distillery reached out to me which shows they care about their product. That goes far with me. Update... I have now tasted the R6 Distillery Bourbon Whiskey. Very pleasant to the nose with light vanilla. Taste is smooth and not sharp. The taste is in my wheelhouse of Bourbons. Sweet, smooth vanilla, light Carmel. I hear you can get a bottle at COSTCO and i saw one on the shelf at the local convenience store in Gundo. I would recommend it.

      Great quality! We received selection of bourbons as a splendid gift from our friend. That was a first time we tried this product. We tested and tested different ones and enjoyed it so much, but did not have even a hint of a headache next morning! Amazing!

      Victor Alpha's Review Sourced from Google

      Great speakeasy, fine spirits, nice atmosphere. Drawback is licensing restrictions - only one cocktail or 1.5 oz total in spirits. Beers are unlimited. Another flaw is when a private event is scheduled, no notice is posted on the website, meaning if you’re traveling here from afar, you will have to travel right back spiritless and hopless. Edit: When I checked the website I did not see the notice about the private event. If you say it was posted, then it was my fault for not being thorough. Also, the state did not want your missing stars and I have too many myself. They are all yours. And the gin was delicious. Cheers!

      I am thoroughly pleased with your companies ability to deliver an exceptional working relationship that has lead to an eloquently executed client experience. Isadora Digital Agency took a much-needed concierge approach to our relationship and helped us define our goals as well as align the expectations of the officers of our company. Our needs and vision were sophisticated but you helped us to achieve our vision through a multitude of legal and compliance challenges while still creating a warm and textured environment for our clients to engage with us. There have been multiple occasions the agency has gone exceptionally above and beyond to make this project a success – had we partnered with some of the other 9 design companies we were engaged with, I don’t feel confident that they would have provided the white glove service that we received from your firm. Let me summarize: Isadora delivers enterprise style service and results with the client engagement and human interaction of a boutique firm.
