11 Testimonials

I like to express my appreciation towards Simon from themosse of what he done of our site. Simon is very experience and can do also every request I have requested. Highly recommanded for everyone for a great quality site.!



I have no hesitation in recommending Simon. From the outset Simon was a great communicator and responsive, he hit all his deadlines and commitments. I was new to e-commerce and I came to Simon with a "loose" brief. Simon was able to interpret my requirements and show me Shopify's capabilities and limitations. I was really pleased with the result that I got.
Simon was a great choice for me. He has a good eye for design and produces strong copy. I didn't realise how important this was until he showed me his draft work. His little touches really lifted the site.
I am still working with Simon. He is very responsive when it comes to "tweaks" and new ideas. It is very reassuring that I have an expert "on the team" when my business is so dependent on my website.

All for Love London

Simon was a pleasure to work with from the start. He was recommended to me by a mutual friend and fellow web developer so I already had great confidence in his work. He was patient, kind, always helpful and super efficient. I could not be happier with my website and I am very grateful for all of his hard work. I shall definitely always be using Simon to help with any future developments I want to make to the site. I would recommend him to anyone, including the Queen.

Blue Samovar

Working with themosse took all the hassle out of our Shopify and website setup. There was no geeky language or jargon that could have left us feeling excluded from the process - everything was clearly explained to us in simple layman's terms. He never missd a deadline and never complained when we changed our minds or needed extra support. Infact, he couldn't have been more helpful and friendly as well as being super-efficient. What more could you ask for? At Blue Samovar we'd happily recommend themosse to anyone in need of support with setting up Shopify and website services.

Simon was very helpful, and did the required work fast and efficiently. I would recommend him.

Outpost Gallery

I can't recommend Simon highly enough. Not only was he very knowledgeable, helpful and quick at his job, but in my opinion his fee was also reasonable. I will definitely be working with Simon again.
