Two problems. One team. One engagement.
We handle modernization and AI integration together same engineers, same timeline, one bill.
Modernize Legacy Systems
Your 10-year-old monolith is slowing down your team, blocking new features, and creating security risks. We decompose it into modern microservices, move it to the cloud, and set up CI/CD — so your team ships weekly instead of quarterly.
Build AI Into Your Products
Your competitors are adding AI-powered features. Your architecture needs to support it. We integrate LLMs, intelligent automation, predictive analytics, and AI agents directly into your modernized platform — not as a bolt-on, but as a core capability.
Scale Your Engineering Team
Need more engineers who understand both legacy systems AND modern AI? We embed dedicated teams (4-12 engineers) into your workflow, with a US-based technical lead, 4-hour timezone overlap, and 94% retention rate.
Real results. Real systems. Real numbers.

What our clients say
Real feedback from companies we’ve worked with some for nearly a decade.
Rich Christiano
“Hi, this is Rich Christiano from ChristianMovies.com. We’ve been selling Christian DVDs online since 1997 and recently had some issues with our Magento backend. It’s tough to find reliable, knowledgeable help—but then I found Steve Johnson and the i-Verve team through a customer referral. They quickly resolved our major issues, communicated daily with updates, and were very reasonable to work with. I highly recommend them and will definitely reach out to them again when needed. Great team, great experience!”
Bruce Warner
“Hi, I’m Bruce, IT manager for a small nutritional supplement company in Arizona. We don’t have in-house programmers, so we hired i-Verve for custom development. They assigned us a project manager who works on our schedule, responds quickly, and resolves our issues fast. They’ve done a great job, and I highly recommend them for any programming or e-commerce needs.”
Andy Alexander
“Hi, this is Andy Alexander from Onestone Biblical Resources. We’ve used Magento on our site for years and were initially cautious about outside help. After checking references, we started working with Steve Johnson and his team. For the past three months, they’ve handled updates and security fixes reliably. I’m very pleased with their work and highly recommend them for Magento projects.”
Ryan
“Hi, I’m Ryan from School Lockers LLC. We needed help customizing a complex shipping module in Magento, and i-Verve delivered exactly what we needed. They were professional, fast, and got it working perfectly. We’ve continued working with them for site maintenance and improvements and are very happy with their ongoing support. Highly recommend i-Verve!”
John Wills
“Hi, I’m John from eLogbooks. We’ve been working with i-Verve on mobile app development and are now on our third project with them. They stepped in after another company let us down and finished the job ahead of schedule. Their communication and project management are excellent. We’re very happy and plan to keep working with them.”
Mike Lacey
“Hi, I’m Mike Lacey, Director of Marketing at North Cal Wood Products. We hired i-Verve to migrate our site from Interspire to Magento. Jeff Harvey was professional, informative, and easy to work with. The team delivered great results at a fair price, and we’re so satisfied that we’ve continued with their maintenance services. Highly recommend i-Verve!”
Jeff Figley
“Hi, I’m Jeff Figley, owner of King Blossom Guitars. I needed a professional website to match the quality of my custom guitars, and i-Verve delivered exactly that. It looks great, works flawlessly across devices, integrates with my UPS account, and includes smooth animations. The team was highly responsive and easy to work with. I highly recommend Steve and his team!”
Tracy Davidson
“Aloha, I’m Tracy Davidson from Hawaii Sales and Marketing. I hired i-Verve to build a website, app, and mobile game—and they did a fabulous job! The app, Tracey’s Maps, turned out great. Steve Johnson and the team stayed in constant contact and were very diligent. I highly recommend them for web, app, or game development.”
Aziz Elia
“I have been working with a team of developers at i-Verve for a year. I can frankly tell you that my experience with the team has been amazing. They are responsive an timely on their delivery of the solutions I need. I recommend them highly.”
Brandon Schuchardt
“Worth Every Penny
Friendly, professional, great team. They did what I paid for them to do. Very excited. I see having them do work for me again in the near future. Thanks Steve.”
David
“We have been working with i-Verve since end of last year as an extension to our core team. We have steadily increased the team size at i-Verve which is a sign of our satisfaction with them. We experience a solid performance, little rotation and lot’s of fun interacting with the team while teaching our goals.”
Elisabeth Hoff
“I-verve have been creating a new website for me based on a detailed brief from me & my team. They are efficient, professional and extremely good at what they do.
I could not be happier with the service I have received and can recommend them highly.”
Frazer Cannadine
“The team at i-verve were great people to deal with. From our initial engagement, they gave me the confidence that they knew what they were doing. They took our old website and expanded on the existing content. They used a new theme to make it better presented, easier on the eye, more logical to get between pages, added new images and improved some of the page structure. They helped us with the go live and they made several tweaks to the content upon 2nd review. I would use them again without a doubt.”
Michelle Elia
“I-Verve is great to work with. The developers are fast and knowledgeable. We have been very pleased with their work over the last few months. I would recommend them to anyone looking to supplement their US-based development staff.”
Nadia Arain
“Dave and team, have done an absolutely mindblowing job with my store. I initially found them on a freelancing platform and they have been nothing but professional and supportive to my custom made store that I found very hard for people to understand, let alone design. Their rates are super affordable and I would return to them for any of my work.”
Nadia du Plooy
“We are happy with our choice of using iVerve. After a long and extensive search for the right agency, we decided on iVerve. We were not disappointed. A combination of good value, good communication, responsiveness, delivering on tasks, and having a single point of contact, all contributed to the success of our M2 migration. The webshop was up and running smoothly and the team’s technical knowledge ensured that the back and front-end were set up to our wishes.”
Nicholas Manske
“Solid Work at creating API for Interview Scheduling App
They did a great job of creating an API for syncing our interview scheduling app with our website. Good communication, reliable, highly recommend!”
Oliver Hinsenbrock
“We have been working with Peter and his team on various projects. We are always impressed by the quality and professionalism regarding communication and code quality. You will be receiving daily status reports and previews of tasks to come for the next day(s). The quality of code is definitely far above average. If quality is your first priority, Peter and his team should be definitely among your first choice. We are looking forward to projects to come.”
Richard Meredith
“Very quick and helpful! Still answering question i have even after the job is finished.”
Zak DeBrine
“I started working with I-Verve a few months back to finish out an SDK that was being built. The I-Verve team immediately started working and made sure to get the right developers working on our project. Not only are we getting the project finished, but the team went above and beyond to add some cool features that weren’t in the original scope. Highly recommend.”
Nikolas Rajkovic
“We worked with i-Verve to modernize our application and handle ongoing maintenance. Their team is technically strong, responsive, and flexible—even with our complex requirements. Performance, security, and UX all improved. While some communication challenges are expected across distances, they’ve been professional and efficient. Overall, we’re very satisfied and highly recommend them!”
Hafiz Ali
“I’ve worked with i-Verve for a few months and they’ve exceeded expectations. They were deeply involved in my WebApp development, offering valuable input based on past experience. The team was skilled, motivated, and incredibly responsive—often following up before I did! Great communication and dedication. I highly recommend i-Verve and will continue working with them.”
David Voute
“We have been working with i-Verve since end of last year as an extension to our core team. We have steadily increased the team size at i-Verve which is a sign of our satisfaction with them. We experience a solid performance, little rotation and lot’s of fun interacting with the team while teaching our goals.”
Ron Wilson
“Working with Peter and his team is an absolute pleasure. They are not only competent in IT, but also project management. Because of their continual interactions with me, the project was finished successfully and to a higher standard than expected. I will always work with this company for anything IT.”
Tero Juola
“I have been i-Verve’s customer since 2014 and they have done about dozen Magento 1 and Magento 2 projects for me. Never failed, always on budget and schedule. I can sincerely and warmly recommend this company for Magento projects.”
Ryan Russell
“The i-Verve INC team is great! They are timely, responsive and do great work. I have been using them for a year now and can’t see where I would be without them.”
Sharon Maister
“I was referred to this company after several thousands of dollars and numerous attempts to set up a basic website. Extremely skeptical but desperate for results I decided to give them a try. I am VERY impressed with how responsive, polite and professional everyone has been. I will DEFINITELY continue to use them and will gladly refer them out.”
Mark Food
“Peter & his team carried out everything we wanted in the migration of our e-comm site from M1 to M2. Although we did the design in the UK the guys implanted everything & were happy to amend to suit our requirements. They have also done an excellent job in helping post launch to iron out any niggles. Great job guys”
Mik Rub
“i-Verve worked on my project every day until it was finished. They use tools like Skype, Basecamp and email to keep in touch and make the whole project go down very well. They was right at my budget and do things even after the job was done.
I like these guys and gals they do not bull crap you and will do what is needed to get the job done and keep their customer happy. Even after job is done and fully paid they still go out of their way to help you.”
Bill Zielinski
“I have 2 complicated Magento E-commerce sites which required a great amount of attention to detail as well as some custom coding. I worked with a domestic (US based) company on one of the sites, and I-Verve on the other. While the domestic company produced a website full of errors, mistakes, and glitches, I-Verve produced a beautiful site that was, aesthetically, exactly what I wanted. The website works perfectly and I can trust the integrity and work ethic of the I-Verve team. They really do everything it takes to get the project done AND to make sure I am happy with the outcome.”
