Software Development Review from Michael S.
We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

Azumo helped us migrate our existing UIs into a new framework, creating reusable components and the infrastructure needed for future development. The developer they assigned became a seamless part of our team, always punctual, responsive, and a great fit overall.

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

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.

From my initial consultation to the completion of the development process, the entire team at AppStem has been a pleasure to work with. With so many Mobile App Development companies to choose from, it's important to chose one who is willing to understand your needs and clearly outline a game plan before getting into development. If you're looking for more of a partner than just an agency, you're in good hands with AppStem.

Roberto Aponte's Review Sourced from Google
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.

Every person on their team is skilled, professional and has great communication. They helped me do a Photoshoot for my e-commerce products.

Working with Brandastic to build our businesses website was a seamless experience. As a legal professional, I needed a site that was not only visually impressive but also technically sound for SEO.
Their team excels at WordPress development and truly understands how to translate complex service offerings into a user-friendly interface.
Since launching, we’ve seen a noticeable improvement in our digital presence. If you’re looking for a top-tier digital marketing agency in Orange County, I highly recommend Justin / Sandy and the rest of the Brandastic team
