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.

For example, with Yalantis' guidance, the client's developers explore the Go language. The primary reason the client chose Yalantis is its strong organizational and project management skills. It's not just about the developers; Yalantis provides a comprehensive support framework, ensuring that a project manager is consistently present. (Verified via email)

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!

Small Businesses Website Development Review from Kris Meyer
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.

Rebecca Larry's Review Sourced from Google
Had an Interview here and the old wrinkly man who interviewed me was extremely rude and passive aggressive. The best time that came out of the interview was that I did not get this job, if I had I would have 10000% quit because of the hostile and aggressive environment. do not use this company unless you enjoy talking to rude old people.
Krish Narsinghani's Review Sourced from Google
Tried to get one of my Pakistani artists studio time here but they are super selective about who they work with. We offered to do promo and pay for a few hours each week instead of booking their usual five hour minimum but extreme rules for a studio.
