SITE IT NOW Reviews & Testimonials
Web Design Review from Barbara Schmal
I decided to go with Site It Now because they are in Chicago IL and I am in Florida. I wanted a website developer in the US. I checked out their website and was impressed with the information I found. I am very pleased with my website and especially pleased with how they communicate with their customers. A real phone call, text, email all day every day until the project was completed.

Zealous System Reviews & Testimonials
Software Development Review from Grzegorz Grabczak
We worked with Zealous System on an AI-powered fraud triage solution for one of our clients in the Europe financial services sector. The project involved a complex fraud investigation workflow where analysts were handling a large number of alerts and gathering information from multiple systems. Zealous System worked closely with us to understand the requirements, existing processes and expectations of the end client before moving into development. The team developed an AI-powered fraud triage agent that brings relevant information together, helps prioritise alerts and provides explainable recommendations while keeping human analysts involved in important decisions. What I appreciated was the team's ability to understand both the business and technical sides of the project. Communication was consistent, and they were responsive when requirements evolved during development and testing. The solution helped streamline the investigation process and reduce the amount of repetitive manual work involved in reviewing fraud alerts. Overall, we had a positive experience working with Zealous System. They were a reliable technology partner for us on this project, particularly given the complexity of introducing AI into a financial services environment.
DIPAK VAIDH's Review Sourced from Google
I visited Zealous System on 16th June 2025 for the walk-in interview announced on LinkedIn for interns/freshers in Python, PHP, WordPress, .Net, and QA roles. Despite clearly stating it was open for freshers, upon arrival, all Python candidates, including myself and my sister, were told they only accept those with prior experience, as interns are directly placed on live projects. This information was never mentioned in the post. The company blamed the marketing team for the misleading post. This experience wasted our valuable time, energy, and travel expenses. I urge the company to coordinate better internally and post accurate job/internship information to avoid misguiding freshers who genuinely seek opportunities.
Ravi Prajapati's Review Sourced from Google
Zealous System is outstanding when it comes to AI development! Their team helped us build a smart, AI-powered software solution that completely transformed how we manage data and customer interactions. They explained complex AI concepts in simple terms and delivered a solution that works flawlessly. From planning to post-launch support, everything was smooth and professional. Highly recommended if you're looking for reliable AI experts!

Web Development Review from Kirill Kudymov
Oyova designed and developed a web platform that allows users to access and post information relating to MS. Without wireframes, their team developed much of the design on their own, taking into account that the interface needed to be very user-friendly for our audience.
Brittany Grunzinger's Review Sourced from Google
Oyova has continuously proven to be a fantastic partner to our team! They are knowledgable, easy to work with, and come to the table ready to collaborate. When seeking a business relationship, the hope is always that it’s seamless, and that’s exactly the experience we’ve had with them. Whether we have a simple question or a complex need, they remain a team that we can rely on. My primary point-of-contact is Beth, and she’s been wonderful! She’s not only great at keeping things on track, she’s also kind and approachable. In fact, I’ve collaborated with multiple members at Oyova and everyone has made it easy to build a long-term, trusting relationship with them. If you have the chance, work with them. You’ll be glad you did!
S. christian's Review Sourced from Google
We partnered with Oyova for outsourced development work, and the experience was outstanding. From the very beginning, their team demonstrated a deep understanding of our project needs and delivered high-quality work on time and within budget.A special shoutout to our account manager, Beth Rener, who always went above and beyond to ensure a seamless process. She was incredibly responsive, proactive, and always one step ahead in managing the projects. Whether it was addressing questions, providing updates, or making sure everything stayed on track, her attention to detail and commitment to our success truly stood out.Highly recommend Oyova and Beth!

Austin rebuilt our website from the ground up and helped turn Bespoke Tint & PPF into one of the top tint brands in Bellevue. The work started with a full redesign of our website, including branding, copywriting, conversion improvements, mobile optimization, and development. The new site immediately performed better and generated more leads after launch.After the website launch, we continued working together on SEO, AI search optimization, paid advertising support, analytics, A/B testing, and ongoing marketing strategy. He also helped improve our review visibility, local search presence, and overall positioning online.What started as a website project became an ongoing growth partnership focused on increasing traffic, leads, and customer acquisition.
Mark Manes's Review Sourced from Google
We needed a custom solution to parse various PDF formats, clean the extracted data using AI, and seamlessly store it in a database. A previous vendor failed to handle our document variety, but this team delivered flawlessly. They built exactly what we asked for—accurate parsing, intelligent data cleaning, and structured database storage. Highly recommend!
Md. Mirajul Islam's Review Sourced from Google
We were ranking well on Google but weren’t getting any clients from ChatGPT or other AI platforms. I reached out to them for help with AEO/SEO, and within a week of launching the changes, we started getting website traffic from ChatGPT. It has been about two months, and now we are also getting traffic from Grok and Gemini. Very thankful for the results.

Uncommon Joe built a beautiful website for us with a lot of content. They are very responsive to changes and updates. They also have a lot of technical expertise if you are using your URL hosting company for name servers for your email accounts. Joe can get that all set up for you too. Super easy!!
Monkey Around's Review Sourced from Google
We're so glad Joe was the one who designed our website! He was so patient will all our revisions, worked with everything we gave him, and operated really well under a time crunch. He also had good insight as to what would be optimal all the way around for presentation and visuals. As our business grows and expands, he's definitely who we'll ask to take any website needs and projects on!
Rimrock Electric's Review Sourced from Google
Joe took our very outdated and rather embarrassing website, and transformed it into something professional looking and one that we could be proud of. We are no longer ashamed when a client says they checked out our website. Joe is a pleasure to work with and has great ideas and feedback. Thanks, Joe!
