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

Bradley Halvorson's Review Sourced from Google
Absolute crap company, I'm currently filing a lawsuit against them for defamation because they like to tamper with things on the website and are resentful little children. They give you attitude when you asked for what you purchased. Struggle to get my domain and are deleting reviews after I got it.

RUN AWAY from this company! Supposedly located in California. They sold me a package to design the branding, website, and social media for my company for $1500.00. "EVERYTHING" for $1500.00. Have paid over $6000.00 and I have NO control over the material I paid for. They send you everything in formats you cannot use or convert. They want to keep a hold of you to keep asking for money!!!!!! NEVER send anything to print through them!!! Ordered some business cards and brochures and have never received the brochures. To this day I have not received a single invoice or receipt of anything of what I have paid, including the design of the logo, the purchase of the domain and many other things. DO NOT RECOMMEND.

David McCurrach's Review Sourced from Google
I believe this company is a criminal enterprise. They are also known as Creative Company and Sketch Profs. Creative Company made a $2,500 unauthorized withdrawal from my checking account. When I protested the transaction, Uptown Logo Design provided a fake receipt, fake transaction and activity logs and fake emails supporting the charge to my account. It was an elaborate and thorough fraud. I'm sure they've used similar fabricated documents before with other people they've ripped off. I reported them to the FTC and FBI.

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

Victor Babenko's Review Sourced from Google
This would’ve been an amazing venue if there was any ventilation at all, and the entire space wasn’t instantly getting full of smoke from the smoking area. The amount or second hand smoke you’re getting here is insane. Ventilation here is basically “let’s just keep the doors open and get all the smoke back in”.

Holly Harris's Review Sourced from Google
The place is spacious. Get to the bathroom early as it is unisex and there are only three. The art displays are super cool with an interactive French one covering a wall and another heat sensitive one that is like the exploratorium.

Peter Donaldson's Review Sourced from Google
Had a really nice evening with some favorite music played. In a different way than I had experienced before, but it was a unique experience overall and one I would certainly consider again in the future. The skill level of the quartet was top notch and together they really produced a rich and magical performance, enhanced by the candlelight that illuminated the stage. It only lasted an hour, but that was enough to fit a lot of crowd-pleasing songs from both ABBA and Queen.
