Mobile App Development Review from Noah Petraitis
AgileTech excelled in supporting our project from initial mock-ups through to the final delivery on the App Store, incorporating data analytics that we could easily share with our customers. The scope of work included mock-up creation, UI/UX design, interactive prototyping, app development, rigorous testing, and setting up a secure production environment on AWS, culminating in the apps release on both iOS and Android platforms.
Software Development Review from Selva Jayaraman
Working with AgileTech has been an amazing experience, especially when it comes to creating a personalized e-learning program for our IT services business. We were pleasantly surprised by how adaptable and scalable the platform developed by the AgileTech Team was. Their proficiency with user-friendly course administration and community participation technologies enabled us to provide a thorough instructional resource catered to our customers' particular requirements. The platform has greatly improved our operational efficiency, and we are amazed by its capacity to manage heavy traffic with ease and offer comprehensive reporting and analytics. The platform remained successful and user-friendly because of the team's dedication to continuous support and their quick response to criticism. For any organization looking to create innovative and reliable digital solutions, we wholeheartedly recommend AgileTech as a partner.
Software Development Review from Preci Capiral
AgileTech provided a superb Learning Management System (LMS) that creatively and precisely addressed the intricate needs of our organization. Within a scalable, completely customizable platform, the LMS made it possible to create comprehensive courses, administer student tests, engage the community, and obtain real-time data insights. AgileTech's modular and agile approach made sure that every component, from the user-friendly course builder to the sophisticated analytics and communication tools, was customized to meet our demands despite the difficulties of developing such a feature-rich system. In order to guarantee perfect scalability and zero downtime, even with high user concurrency, AgileTech used a potent tech stack that included PHP, React, and AWS. Their post-launch assistance, which included frequent training sessions and upgrades, gave our staff the means to fully use the LMS's potential. This project was a testament to AgileTech's technical skill, rapid deployment, and dedication, making them an outstanding choice for educational technology development.

Applications Review from Anonymous
Working with A1QA has been exceptional since the very beginning. Their professionalism, efficiency, and quality of work often exceed what we’ve seen from much larger providers. From the early planning stages through test execution and continuous improvements, the team has shown strong expertise and maintained clear, reliable communication. Their dedicated focus on QA has given us an experienced group that manages the entire process with little need for oversight on our side. They are true experts in their field.

Highly qualified staff and quick search for new employees. The outstaffed guys have high technical expertise and are well-versed in the latest technologies. My overall experience with the service has been positive. Their guys have integrated well with our in-house staff and contributed significantly to projects.
Software Testing Review from Rick Fox
The team's clear communication and hardworking nature made them easy to work with. Tasks included writing and managing test cases and conducting various QA tests, such as feature acceptance and regression testing. Worked alongside internal teams to ensure we tested the priority each Day & Week of the project. Issues raised communicated out so any blockers were prioritised appropriately.

Web Design Review from Abraham Meidan
Our old website was stuck in time, clunky, outdated, and honestly didn’t do our work any justice. We knew we needed a complete overhaul. The goal was simple: create a modern, polished platform that reflects what WizSoft does today, helps potential clients quickly understand our products, and builds real trust from the first click.They redesigned everything from the ground up. full website design and development, clear and scalable layouts, product detail pages that actually explain things well, and a clean structure that’s easy to navigate. They gave us mockups for every screen, and we worked closely on content using shared docs. Revisions were fast, honest, and collaborative. Nothing ever felt like a hassle.The impact was almost immediate. Within weeks of launch, our traffic jumped over some unimaginable amount of percentage and that was without any real marketing push. Inquiries doubled. But more than just numbers, we noticed better leads. Real people, serious conversations, and more trust upfront. And for the first time, our brand felt aligned with the quality of our product.
Web Design Review from Paulina Sadlowska
Our website had grown tired. It was built over five years ago and no longer reflected the energy, diversity, or ambition of who we are today. It was hard to navigate, uninspiring to look at, and frankly didn't connect with our students or community the way it needed to. We wanted more than just a cosmetic upgrade, we needed a full redesign, one that would feel modern, intuitive, and purposeful.Within weeks of launch, we saw a measurable shift. Web traffic jumped by over 40%, inquiries from prospective students doubled, and event sign-ups started to rise steadily. But more than the numbers, the feedback changed. Students said it was easier to find what they needed. Parents could navigate with less frustration. Staff felt proud to share the site again. It was a transformation and not just in design, but in confidence.This wasn't just a web project. It was a turning point. We walked away with more than a new site. We walked away with clarity, pride, and a stronger digital voice for Calderdale College. If you're serious about building a site that truly reflects who you are and what you stand for, Hook UX is the team to trust.
Web Design Review from Rahul Aggarwal
We brought in HookUX to rebuild our site from the ground up. the old one just wasnt working anymore. it was slow. We needed a cleaner look. better user flow. stronger mobile experience. and something easier to manage in-house.they did everything. from auditing the site to helping us plan out every step. they redesigned the homepage and core pages to feel modern but still on-brand. made navigation simpler. added a better ecom setup so our community could use it with fewer clicks. cleaned up the backend. helped with seo too so more folks could find us. they even trained our team on how to use it all. felt like they thought of everything.

Steven Alessandro's Review Sourced from Google
BRK Global Marketing and Jack Burke’s creative team absolutely exceeded my expectations.From the very beginning, BRK designed and built an original, standout brand for Devon Creek Landscaping that truly set us apart in the landscaping community. They created our logo and carried it seamlessly across everything—vehicle wraps, uniforms, brochures, social media frames, swag, digital and print advertising, and even our trade show booth.What really impressed me was the depth of strategy behind the creativity. BRK developed our brand voice, brand personality, and comprehensive brand guidelines, which became the foundation of our franchise marketing strategy system when we launched the brand. Everything was thoughtful, consistent, and built for long-term growth.Afterward, we had the pleasure of working with BRK again to design my personal Steven Alessandro brand as a thought leader and consultant for franchise owners and business leaders across the U.S. Once again, they hit the target.Jack and his team were incredibly responsive, listened closely to what I needed, and delivered an end result that was truly beyond my expectations. Their originality, attention to detail, and ability to translate vision into a powerful brand is unmatched.If you’re looking to stand out and build a brand that actually works—not just looks good—BRK Global Marketing is the team to trust.
Brian Gates's Review Sourced from Google
I’ve had the pleasure of working with BRK Global Marketing on multiple initiatives, starting with branding and a new logo for MRC over eighteen years ago, and now continuing with the RubberBond Elements brand and marketing strategy.What truly stands out is the longevity and consistency of strong deliverables that Jack and his team provide. Every project is approached with creativity, originality, and a clear strategic vision. BRK doesn’t just meet expectations—they consistently overdeliver.Their ability to evolve brands while maintaining clarity and impact has made them a trusted partner. I’m excited to continue working together and are already moving forward into 2026 with a new brand awareness strategy. Highly recommend BRK Global Marketing to any organization looking for creative excellence and dependable results.

Anıl Ergez's Review Sourced from Google
I worked with Nova Era Agency, a San Francisco-based web design agency, for a full website redesign and couldn’t be happier with the results. From the beginning, their team was professional, responsive, and clearly experienced in building modern, high-performing websites. They took the time to understand my business goals and delivered a clean, visually polished site that’s fast, user-friendly, and optimized for conversions.What really stood out was their attention to detail and clear communication throughout the entire process from strategy and UX to design and launch. It felt great working with a local SF web design team that truly understands both branding and performance. If you’re looking for a reliable web design agency in San Francisco, I highly recommend Nova Era Agency.
Cevher Ersoy's Review Sourced from Google
i worked with Nova Era Agency, a San Francisco web design and SEO agency, to build a website for my online book business, and the experience has been outstanding. The site they designed looks great, is easy to use, and actually helps convert visitors into customers instead of just sitting there looking nice.I’m also using their ongoing SEO services, and the impact on my business has honestly been amazing. Over time, I’ve seen more organic traffic, better visibility on Google, and a noticeable increase in sales. It’s clear they understand SEO for online businesses, not just basic optimization.What I appreciate most is that they’re consistent and proactive. They don’t disappear after launch they keep improving the site and SEO month after month. If you’re looking for a reliable web design and SEO agency in San Francisco, especially for an e-commerce or online business, I highly recommend Nova Era Agency.

Junette Kearns's Review Sourced from Google
EZ Rankings is extremely disappointing.The services did not deliver the quality that was promised. The company charges premium prices for services such as website design, SEO, and SMO, but the results fell far short of expectations. Despite significant investment, I did not see the level of progress, performance, or return that was discussed during the sales process.Communication was another major issue. It often felt difficult to get clear answers, timely updates, or meaningful support when concerns were raised. The team did not appear well-coordinated, and resolving issues took much longer than expected.I also felt that expectations were set very aggressively during the sales stage, but the actual delivery did not match those expectations. Promises regarding growth, rankings, and overall project outcomes seemed much stronger than what was ultimately achieved.For businesses considering SEO, SMO, or web development services, I would recommend asking detailed questions about deliverables, timelines, and measurable results before signing a contract. Based on my experience, I would not choose to work with this company again.
