Digital Marketing Review from Lucy Saint-Antonin
I really enjoyed working with the Codedesign team. They have a very methodical approach, first analysing and understanding business needs and then proposing the most appropriate strategy to meet those needs. They were very responsive throughout the digital project that we worked on with them, and demonstrated strong expertise on topics such as Google and Meta ads, and SEO strategy, helping us to increase traffic and conversions. I wouldn't hesitate to recommend them for any project requiring digital marketing expertise.
Digital Marketing Review from Rita Corrêa Mendes
I chose to work with Code Design on the launch of Grupo Hug because I believe they possess essential characteristics that are extremely important to me in a digital agency: team qualitification, digital expertise, credibility, client results orientation, a holistic digital approach always with an interest in going beyond a simple objectives briefing. They are very responsive and collaborative, and we have a fluid and transparent communication. They are available, always seeking to meet our needs reactively but also proactively.

Email Marketing Review from Ramin Schultz
JP was a huge help in creating eye-catching designs for my email campaigns. He understood exactly what I needed and delivered polished, professional visuals that really boosted the overall look of my emails. His attention to detail and creativity made a big difference, and I'm very happy with the results!
Email Marketing Review from Jordan Lingohr
JP and he team at EcommerceBoost are such a breath of fresh air. We've wasted an ungodly amount of time, money and every into looking for a reputable email marketing agency for our e-commerce brands, but once we had the kick-off call with JP, we knew we'd found the right (and last) email marketing agency. That was a few years ago -- working with EcommerceBoost was one of the best choices/hires we've made in a while.
CRM Emailing Review from Luciano Viterale
JP and the team at Ecommerce Boost have been incredibly helpful. Not only did they map out our email funnels and help us convert more subscribers into paying customers they generated ideas for the copy and guided us throughout the process. They made it clear which strategy to follow, why it would work, and the results to expect. They were spot on and these sequences still drive revenue for our business! Thanks JP and team!

UI/UX Design Review from michelle G
The quality has been excellent. Working with Nurency has been really good. We come to them with ideas and they work through the processes. After some back and forth, they improve upon what we gave them. We dont have any quantitative data because we havent fully deployed the solution. The project management has been great as well. The person we dealt with was on top of everything. They kept up to date with timeline and budget concerns. We used some tools during the design process, but nothing was set.
UI/UX Design Review from Rohan S
We provided Nurency with our idea and vision of what we wanted to accomplish, who the users of our platform would be, what value we wanted to provide to each user, and what features we wanted to implement. After that, nurency held a series of workshops, where we put together a list of features, inputs, and outputs. Based on that, they were able to give us the flow and options for the UX, as well as what the screens would look like. Their team also engaged with our potential customers; they had interviews with them to validate our business plan, including the features and functions. They gave us feedback on the value that our customers were looking for as well. They were able to map everything out in the UI/UX using Figma.
UI/UX Design Review from Andreas Birnik
Nurency is providing us with UI/UX design services. They're optimizing our existing solution and all its underlying constraints. The team has worked with our technical and engineering teams to ensure they understand the challenges of our backend and then interpreted what we needed for the frontend design. We started with a UX research phase where we did outreach to existing customers, and they worked to go through our existing UX to map out all the essential features that needed to be deployed.

Web Design Review from Daniel Hudson
I first came across Navicosoft while searching for the best hosting company in London. Their strong presence on review platforms like Google, Trustpilot, HostAdvice, SuperbCompanies, and Clutch immediately stood out, and the consistently positive feedback gave me the confidence to get in touch.From day one, the team were professional, responsive, and clearly understood the needs of a construction and renovation company like ours. They registered our domain in under a minute, set us up with a solid and affordable hosting plan for a construction company, and managed everything through cPanel on their London-based Equinix servers giving us fast, secure, and reliable performance.The bigger project was designing and developing our new website. We needed something that truly reflected Cezar Renovations from our home extensions, loft conversions, and joinery work to our timber supplies. Navicosoft delivered a fully bespoke WordPress website with British English content crafted to speak directly to our local audience. The design was clean, modern, and perfectly in line with our industry.What impressed me most was the SEO strategy they built into the site from the start. Within just 34 months, we were ranking for over 526 targeted keyword queries in renovation, construction, external joinery, plumbing, and electrical services. This directly led to a 45% increase in local enquiries, bringing in exactly the kind of leads we were aiming for.The entire web design and development process was completed within 12 months, right on schedule, and the communication was excellent throughout from the WHMCS client portal to scheduled Google Meet calls and a WhatsApp group for quick updates.In short, Navicosoft has been a fantastic partner technically sharp, creatively skilled, and genuinely committed to delivering results.
Food and Beverage Digital Marketing Review from Faisal Usman
We partnered with Navicosoft to bring our "Mustakshif" Halal food scanner app to life, and the experience was outstanding. Our goal was to develop a user-friendly app for Android and iOS that could accurately scan barcodes to identify Halal food items. Navicosoft's expertise was evident as they seamlessly integrated complex features using Flutter and Dart, ensuring cross-platform functionality and a smooth user experience.What set Navicosoft apart was their deep understanding of our cultural values. They crafted a unique brand identity, including a logo in Arabic calligraphy that perfectly embodies the spirit of "Mustakshif," meaning "Let's explore." Their design team paid meticulous attention to detail, creating custom UX/UI designs that resonate with our target audience.Beyond app development, Navicosoft provided comprehensive digital marketing services that significantly boosted our market presence. They developed a robust website using the Laravel framework, with optimized content and intuitive design. Their SEO strategies, Google Ads campaigns, and social media marketing efforts led to a substantial increase in website traffic and app downloads.Navicosoft's project management was exemplary. With a dedicated team of professionals, they delivered all milestones on time and maintained open, effective communication. Their responsiveness to our needs and willingness to accommodate changes made the collaboration smooth and productive.What impressed us most was their ability to blend technical proficiency with cultural sensitivity. They didn't just build an app; they helped us create a platform that truly connects with our audience. Their holistic approach to digital solutions from development to marketing has positioned Mustakshif as a leader in the dietary food market.In just three months, we witnessed a remarkable ROI with Navicosoft. The "Mustakshif" app achieved over 10+ million product scans, and our website attracted millions of visitors.
Zahra Sheikh's Review Sourced from Google
Review: I cannot thank Navicosoft enough for the transformation they brought to my business. When I first started, I was overwhelmed with how to get my products noticed online. From day one, their team guided me with patience and clear strategies tailored to my brand.I worked with them as my go-to Pinterest marketing agency, and the growth in traffic from Pinterest alone was beyond my expectations. Their expertise as a Meta ads agency and Google ads agency helped me reach the right audience without wasting money, and the results showed in both sales and brand awareness. On top of that, their role as a Facebook marketing agency and Instagram marketing agency gave me consistent engagement and loyal customers who keep coming back.What I appreciate most is that they don’t just run campaigns — they build strategies. As a social media marketing agency, Navicosoft helped me craft a strong brand voice and connect with people who truly resonate with Zahra’s Natural.If you’re a small business owner like me, I highly recommend Navicosoft in Melbourne. They’re professional, supportive, and deliver real results. My journey with them has been nothing short of empowering.– Zahra SheikhOwner, Zahra’s Natural

Every challenge was met with a smart, efficient solution, and they consistently exceeded expectations.What really sets NerdCow apart is how different they are from other developer companies I’ve worked with in the past, more agile, more collaborative, and genuinely invested in delivering quality.Worth every penny. Highly recommend.

Wow!! What a great team and business to work with. We recently built a fully functional site with Nerd Cow and can honestly say it is one of the best experiences I've had in building a site. The collaborative prototype approach is innovative and agile in its design, the team are full of ideas and the quality of the end product is top of the line. The entire design and build from concept to live site took exactly 4 weeks, quick, efficient and of the highest quality. Thank you Nerd, if I could give 6 stars I would.
Helen Isacke's Review Sourced from Google
I was incredibly lucky to find Nerd Cow when I decided to embark on creating the Trusted Coach Directory. From the initial broad outline, they helped me to add flesh to the bones and used his expertise to develop my ideas into workable processes. The result is a professional looking, contemporary and easy to use website that I'm absolutely delighted with. Nerd Cow continues to help with the ongoing site maintenance and development, with their usual 'can do' attitude, patience and creativity.

Adding to my 5* review from 4 years ago to add that Atomic have continued to provide invaluable advice and support. They are very responsive and great at problem solving. Still 🌟🌟🌟🌟🌟 in 2025!I got quotes/design ideas from several agencies for my website. Atomic stood out from the start. They listened to what I wanted and produced a very comprehensive, detailed and competitive plan. They understood my needs as a small business owner and delivered exactly the aesthetic I was after. They were also incredibly patient with the many tweaks and changes needed along the way. They worked extremely hard to find solutions when challenges arose, their communication skills were exceptional and they were willing to train me up so I could make basic updates and changes myself. Very professional and approachable. I’m really glad I chose them!
