Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.

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

AJProTech Reviews & Testimonials
Clayton Hoarell's Review Sourced from Google
AJProTech provided a feasibility study for my fitness startup. The team was responsive, attentive, and easy to reach. Alex is a great leader and pays attention to detail heavily. He stays actively involved in the process and is a pleasure to do projects with. Overall the feasibility study was very well done. They consider all real world factors like cost and mass production. The team also made sure that they were always in alignment with our organization's goals. The actual deliverables that they provided like 3D renders, engineering solutions, industrial design, and overall roadmap to production are very well done. I would highly recommend the firm to anyone looking to develop a product. Alex and the team's real world experience make them world class in delivering results and helping you navigate the complex space of product development.

I've had the pleasure of working with AJProTech for my startup, My Gun’s Been Moved. We initially connected while we were exhibiting at CES, and they immediately stood out for their professionalism and deep understanding of product development.Throughout the process, Alex and the team have been incredibly thorough and accommodating—from the feasibility study to refining our initial product design. They were especially helpful during a critical time when we were locking down our intellectual property, ensuring that our development process remained smooth and aligned with our long-term goals.Their team is genuinely invested in helping founders bring their vision to life. I highly recommend AJProTech to any founder looking for a reliable and innovative hardware development partner. I;ve loved working with them and am excited to go to market with our product!— Kayla Austin, Founder of My Gun’s Been Moved

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.
