Tepia Reviews & Testimonials

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

K-Optional Software, LLC Reviews & Testimonials

Software Development Review from Michael Levy
Flowty is a blockchain-based platform providing various transaction services around NFTs. K-Optional wears many hats in support of Flowty including Front End, Back End, business strategy, SEO and more.The K-Optional team has been incredible to work with. They are proactive, supportive, smart, thoughtful and, most importantly, fit seamlessly into our team and company culture. To put it succinctly, we tried to hire them full-time...and then tried to buy their company to acqui-hire them.Some of their strengths include: reliability, responsiveness and creativity. There are many groups out there that can perform some version of the work we are looking for. There are not many groups that are responsive at all hours of the day, deliver consistently and able to present data-backed business strategies.

Software Development Review from Jane Smarovozova
We collaborated with K-Optional to develop a custom inventory management dashboard tailored for real estate clients. We provided the creative vision and detailed designs, while their team focused on the software development, ensuring that every element was implemented perfectly. We worked hand-in-hand flawlessly, resulting in a sleek, user-friendly interface that not only looks great but functions seamlessly. The synergy between design and development allowed us to deliver a product that exceeded client expectations, combining aesthetics with powerful functionality.

FAQs About Software Development Companies in the USA
What services do software development companies in the USA provide?
They typically offer full-cycle software, mobile, and web development, UI/UX design, and cloud and development operations (DevOps) as part of their core services. Some companies also provide AI development and digital transformation services to support a business’s continued growth.Â
How much do custom software development services cost in the US?
Custom software development costs in the US start at $90-$160 per hour or $20,000-$500,000 per project, according to data from FullStack Labs. For more complex, enterprise-scale systems, the approximate cost is $500,000 to over $1 million per project. Â
The final cost of custom software development services in the US will depend on project scope, complexity, and integration and regulatory requirements.Â
What is the typical timeframe for custom software development services?
They can take 8-12 weeks for basic MVP development and over 3 years for production-ready enterprise builds. Estimated custom software solution timelines according to Goji Labs: Â
- Small builds: 8-12 weeks for MVPs and 12-24 weeks for full product releaseÂ
- Mid-sized builds: 8-16 weeks for MVPs and 16-40 weeks for complete productsÂ
- Large builds: 12-36 weeks for MVPs and 36-144 weeks for fully deployable productsÂ
What processes and performance benchmarks do top US software companies follow to ensure quality software?
To ensure quality solutions, leading software development companies in the USA perform code reviews, automated checks, clear documentation, and reproducible deployment environments. For instance, reputable companies aim for less than 2% defects before production and 99.5% uptime for system maintenance based on data from Shakuro and BlueGrid.io.Â
How do I check whether a US software development company can handle a company my size?
Primarily, look for case studies that name the client and the person who signed off. Vague, anonymized case studies hide the exact details you need to judge whether a vendor has handled a business like yours.
A good example of this in practice is Designli, which publishes named stories, including work for a mid-market firm with around $100 million in annual revenue.
