Working with Amy and Marcus is an absolute pleasure, they are always so friendly and approachable and are an amazing extension to our team. Right from the start of our website build, Media Lounge have gone out of their way to help with any question I might ask (no matter how ridiculous!), and are always excited to take on new projects with us. Amy has gone above and beyond to bring new ideas to the table and help with our annual planning. I'm so grateful for your support!

CRO Review from Cormac Moylan
We (a large international e-Commerce site) wished to increase sales and revenue by improving our conversion rate. Because of the nuances of the market we operated in, It was important we partnered with an agency that understood our business and the relationship we have with our customers. Lauren, Grace, Jackson, and the entire team from Media Lounge understood this. Their tactics and optimisations were carefully tailored on improving the connection between our business and customers. Every opportunity recommended by Media Lounge was aligned to our business goals and demonstrated their expertise, knowledge, and abilities. I was impressed with their in-depth research, solutions, attention to detail, and most importantly; the resulting uplift from their efforts. They challenged us when we needed challenging, they addressed assumptions that previously impacted sales performance, and they introduced positive change for both our customers and our business. We couldn't be happier to have partnered with Media Lounge.

Web Design Review from Anthony
If you are looking for a web design company that is happy to go that extra mile, i would highly recommend Media Lounge. If you are like me and words like 'DNS' 'or CHRON' are another language to you, then you have found the right company, they appreciate not every one grasps the in and outs of how everything works in a website, so everything is explained to you easily and clearly. On top of this they build websites that not only look inspiring, but more importantly covert browsers to buyers at an incredibly impressive rate. Our's jumped from a fairly industry average at 2% to 6% - overnight.

Chris Freeman Marketing Assistant at Stopford
5.0★
Web Design Review from Chris Freeman
We selected Pixeltree to design and build a redesigned version of our website to bring it into the modern era. The site had been from around 2012 and wasn't doing us any favours in terms of displaying us as a market leader in our niche, so we looked towards James and his team to not only deliver a look and feel of a modern site but also expand on the fairly limited functionality we already had.Working with James and Luke was really positive. They worked with us in-person to understand our customers, what they wanted to achieve, the proposed layout and the components needed. It felt like they became part of the team so it was easy to communicate and get across ideas.We launched the new site in late 2019 and continue to use it to this day because of the range of components they built in, giving me and the team confidence in it's flexibility to achieve our objectives.

Email Marketing Review from Tom Eastman
Melusine Studio are a breath of fresh air. Over the two years we've worked together, they've helped us increase our turnover by +45% by building out a number of automated flows and running 8 campaigns per month. But that's just the end results.They're true professionals and genuinely great to work with. The whole process is very hands-off on our end, which is extremely helpful as my team and I are busy working on other areas of the business. They consistently find new ways of optimising our emails, pop-ups and other areas of our Klaviyo account, and I always feel confident they're squeezing everything they can from this side of the business.Because they're so nice to work with and deliver such great results, we've since partnered with them on a number of other projects too. They've become a core partner in helping us grow, and I can't see that changing any time soon. Thank you Melu and the rest of the team, we really appreciate everything you do!

Barri has a great understanding of marketing strategy and social media. I really valued his insights, particularly around using social platforms to generate leads, which led to more traffic and enquiries through my website. He also helped me set up analytics tools, which have given me a clearer view of what’s working in my marketing. I appreciated how responsive he was whenever I needed to talk something through, and he’s a genuinely nice guy who knows his stuff.

Barri is a great guy to work with. He really knows his stuff, and is very friendly and approachable too. Felt more like an extension of my team than a freelancer. We used him for some AdWords and Analytics assiastance, and customer acquisition strategy. He was very quick to respond and deliver, and very transparent and a great communicator throughout the project. I wouldn’t hesitate to call on him again. Thanks again, Barri!
