Web Design Review from Roshan
This is Roshan, CEO at NanoTherapX. Working with Probey Services for our CRM Development. What stood out most was their stability, consistency, reliability, and a smooth implementation.

Mobile App Development Review from Tejaswini
What stands out most about Probey Services is their discipline-no missed calls, no vague timelines, and no surprises. They built our mobile app with a level of professionalism that made us feel like a priority throughout the project. The delivery was on schedule, the code quality was excellent, and the final product met high standards. Since the app launch, we've seen consistent business growth, and managing customer orders has become much more efficient. I highly recommend Probey Services UK to any business looking for a dependable technology partner.

eCommerce Development Review from Kelly Johnson
Since partnering with Bilberry, we have seen a marked improvement in our websites stability and performance. Their team manages our backlogged issues with such efficiency that our monthly development spend has actually decreased. Estimates are consistently accurate, and we appreciate their proactive communication; if a projects scope evolves, they provide an updated estimate for approval before moving forward. Our monthly sprints are now seamless thanks to their reliable planning and ability to scale resources rapidly to meet even the tightest deadlines.

Web Development Review from Adam Ely, PMP
As Director of Operations at Sands Investment Group, I partnered with Bilberrry to lead the redesign and rebuild of our website, enhance our marketing operations, and streamline internal workflows. We chose Bilberrry for their strong technical capabilities, cultural alignment, and outstanding reputation.
The project followed a well-structured four-phase process: discovery, design, development, and launch. From the beginning, Bilberrry took a strategic and collaborative approach, conducting workshops and technical audits to define a scalable architecture and intuitive user experience. Their team went on to create custom designs for more than 20 pages, build a flexible design system, and ensure the site met key standards for SEO and accessibility.
On the development side, they customized a robust content management system tailored to our needs, incorporating dynamic listing features such as saved searches, email alerts, and early-access content for select users. The new site also connected seamlessly with our internal tools, enabling greater efficiency and automation across teams.
The impact was immediate and significant: we saw a dramatic reduction in manual processes. Our team is now better equipped to manage content independently, while the platform itself is built for long-term scalability and performance.
Throughout the process, Bilberrry was responsive, professional, and incredibly easy to work with. They communicated clearly, incorporated feedback quickly, and consistently brought thoughtful, strategic ideas to the table. Bilberrry's unique blend of strategic insight, technical depth, and design acumen made them an invaluable partner in creating a high-performing, visually polished digital platform tailored to our business.

Chop Dawg Reviews & Testimonials

CEO & Founder at Performance Feedback Platform
4.7★
Mobile App Development Review from Anonymous
Chop Dawg built our performance feedback app from scratch, from scope and wireframes through design and development. The platform allowed knowledge workers to invite colleagues to answer questions, then turned those responses into insights about strengths and workplace perception. Their team felt like a true partner, not just a vendor, and I trusted them to build the solution the right way.

Healthcare Review from Jazmine Dredd
Chop Dawg helped us digitize the staffing side of our healthcare services business by designing and developing iOS and Android apps for nurses and clients, including hospitals and nursing homes. Their team understood the ideas we had in mind and translated them into a clear mobile platform. Tesha was excellent, and the project managers kept every phase organized. They met deadlines, shared ideas we had not considered, and stayed professional throughout. After trying two other companies, Chop Dawg delivered the strongest prototype by far.

Mobile App Development Review from Anonymous
We hired Chop Dawg to build an AI-driven chatbot app that helps users identify the right lawyer or law firm through legal websites. From the start, their knowledge of AI and strong recommendations made them stand out. The project has been handled with a clear process, weekly progress updates, and detailed walkthroughs of each deliverable. They are ahead of schedule, highly engaged, and proactive about using the right resources to strengthen the product. Their enthusiasm, technical ability, and partnership have been excellent.

ANML Reviews & Testimonials
Manuel Colom
UX Director at Yummly
5.0★
Product Design Review from Manuel Colom
Working with ANML on the Yummly app experience and the Yummly Smart Thermometer (IoT) was an outstanding collaboration. Yummly combined personalized recipe discovery, meal planning, and guided cooking into a highly curated food experience, while the Smart Thermometer extended that ecosystem into connected cooking with real-time temperature tracking and assisted preparation workflows. As Director of UX at Yummly, I worked closely with ANML throughout both initiatives, and they operated almost as a seamless extension of our internal design team. Their work consistently demonstrated excellent design craft, strong product thinking, and a highly collaborative mindset. Beyond delivering high-quality UX and visual design, their contribution helped sharpen and strengthen the overall value proposition of the products by making complex cooking experiences feel approachable, premium, and intuitive for users.
Nathan Thornburgh
CEO at Roads and Kingdoms

Web Design Review from Nathan Thornburgh
As Anthony Bourdain's partners, we were approached by CNN to create an immersive digital site that would provide a beautiful home for each destination covered by Bourdain's show Parts Unknown. It was a huge task not least because there were already close to 100 destinations to integrate into a usable global site. But also because the site was meant to live up to the beauty and aesthetic of the television program. And it needed to be done in a way that satisfied both our mainstream luxury advertisers (like LandRover, ANA, and more) but also the famously high standards of Bourdain himself. ANML engaged in this 18-month design and build process with outstanding workmanship and creative decision-making. They navigated wildly different and demanding stakeholders. And in the end they built a site that still looks fresh even nearly a decade later. If you want to make lasting work, there is no one else I could recommend more.

Web Design Review from Alex Lacerda
We partnered with ANML to evolve our digital experience in a way that stayed true to our brand while modernizing how we present our products and story. As a company with a long history in music, it was important to find a partner who could respect that legacy while helping us move forward.
ANML took the time to understand our brand, our audience, and the role our products play for musicians. They built on our existing foundation and translated it into a more cohesive and intuitive experience that better reflects who we are today.
Their team brought strong thinking across UX and design, helping us improve how content is structured, how products are presented, and how users navigate the experience. The collaboration was smooth and highly responsive throughout.
The end result is a more polished and modern experience that still feels authentic to our brand. ANML was a thoughtful and reliable partner, and we would highly recommend them.

DDC has been an excellent partner since we engaged with them in 2023. The DDC team worked with us to completely redesign our website and work to provide ongoing digital marketing services. The DDC team has been responsive, proactive, and thorough with their work. They are also very transparent about how they operate and how much time special projects will require. We have referred DDC to several clients and partners thanks to their outstanding process and product. DDC is a very professional, creative, and well-organized team.

Web Design Review from Sapna Doshi, Ph.D.
My experience working with Design in DC was incredible. Everyone was friendly, approachable, and seemed to genuinely care about helping create the best possible website for my business. They were also invested in making sure the process was one in which I enjoyed and felt taken care of. The regular meetings made me feel like I was a priority and that progress was continually being made. I so appreciated the attention to detail in regards to the user experience. The collaboration in understanding my wishes and desires for the website and user experience was met with patience and paying attention to detail on my behalf. Not only were they taking my suggestions but offering their own to help me maximize the potential of my website. The design and functionality is more than what I could have imagined. I know, undoubtedly, that the work that Design in DC did for me will help my business grow. After wasting money in years past on website designers, I was worried I'd be doing hte same here. I was wrong. I don't think I'll ever need to search for another website designer group again. I would recommend this group to anyone I know. Thank you, Design in DC! It was an absolute pleasure working with all of you!
