      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      Our old website was stuck in time, clunky, outdated, and honestly didn’t do our work any justice.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.
