Rudo Reviews & Testimonials
Joe Baratta Global Head at Blackstone
5.0★
Website Redesign Review from Joe Baratta
We didn't need just a redesign. We needed someone who would slow down and understand what Blackstone is trying to say online. That's where Rudo came in. From the beginning, they listened more than they pitched. They asked about our audience, our priorities, and the parts of the old site that weren't working. They got to work. The process was calm and steady. Wireframes, then design, then development. Feedback was handle with care. Nothing felt rushed, but nothing dragged either. The result is a site that finally feels aligned. It's clear, uncluttered, and it loads fast. Most importantly, it's easier for people to find what they came for. That's had a real impact on how we show up. They questioned things that didn't make sense. They suggested small changes that made a big difference. And they respected our brand without making it feel stiff.

Web Design Review from Joseph Gulbin
I hired Rudo to completely redesign our company website and I could not be happier with the results. We needed a site that could clearly communicate our HR and payroll solutions to decision makers, while also performing well and looking modern. Rudo understood that immediately. From the first call, the Rudo team took time to learn our audience, our product, and our brand voice. They built a site with conversion mind. The new web design is clean, professional, and mobile responsive. Navigation s now intuitive, which has made it much easier for prospects to find product pages, resources, and contact forms. I appreciated their focus on UX for B2B. They suggested clear calls to action and better to organize content for decision makers. Since the new site went live, we have noticed improved user engagement and more inquiries coming through contact forms.

UI/UX Design Review from Oleksandr Yaremenko
Rudo partnered with us on a highly complex DeFi and cross-chain bridge initiative, and their contribution went far beyond simple design work. From the very beginning, their team took time to understand our product vision and the technical challenges that come with building in the Web3 space. This gave us confidence that we were working with a partner who truly understood both the user and the technology side of things.One of the highlights of the collaboration was the strategic product design process they introduced. They didn't just focus on the visuals, but instead made sure that usability and clarity were at the core of every decision. Their user research helped us identify friction points early on, and their insights guided us toward solutions that we wouldn't have discovered on our own.Rudo also delivered a scalable component system and smart UX flows that made the platform intuitive, even for users who are new to DeFi. They balanced technical accuracy with user-friendly design in a way that is rare to find. Every element they produced was aligned with both user needs and our product objectives, which made the entire experience consistent and reliable.Their knowledge of decentralized technologies and Web3 standards really stood out. They were able to translate complex ideas into designs that feel simple and approachable, which is a huge advantage in such a technical industry. On top of that, their attention to detail and commitment to high quality work ensured that the final product not only looked great but also performed well.

Chloe Juyon Review from Google

Chloe Juyon's Review Sourced from Google
We recently worked with Enviral on the development of our first corporate sponsorship pack, and their support has been nothing short of exceptional.They took this on entirely pro-bono, within a very tight turnaround, and delivered work of an incredibly high standard. From the outset, they were responsive, collaborative and genuinely invested in helping us get this right. They quickly understood who we are as a charity and translated that into a clear, confident and beautifully designed document that truly reflects our values.What stood out most was their willingness to go above and beyond. Not only did they produce an outstanding design, they also transferred it onto our own platform so we can update and adapt it in the future — giving us long-term tools and greater self-sufficiency.As a small charity, their responsiveness, efficiency, understanding and generosity have been invaluable. Their support has made a real difference to us at a crucial time.We are deeply grateful and would wholeheartedly recommend Enviral.
