  • Mannix SportsSEOJul 30, 2025

    Working with Ayo and the team at Why Matters has been a game-changer for our business, Mannix Sports. From the outset, their team was professional, insightful, and genuinely invested in us. Thanks to their efforts and expert SEO work, we've seen a noticeable boost in organic traffic, search visibility, and overall user experience. If you're looking for an agency that really knows Shopify and how to get results, Why Matters is the one to trust. Couldn’t recommend them more highly.

  • Fans4lessTheme customizationJul 3, 2025

    Why Matters is alaways great to work with and consistently delivers amazing results. They complete every task I ask for, but they also identify other areas for improvement on my website. They always reach out to discuss these potential changes, ensuring my Shopify site is continuously optimized. I recommend Why Matters to anyone seeking shopify development work.

  • Cast Iron Coffee RoastersOngoing website managementJun 9, 2025

    Excellent service from Ayo and Marcus, they have a clear understanding of our needs and their level of service is fantastic. Definitely recommend them.

  • Laine Brew CoProduct and collection setupMar 20, 2025

    I couldn't rate the Why Matters team more highly. They have been an absolute pleasure to work with on a new section of our shop for a collaboration launch. They delivered on time, and in full, and took the stress out of everything. They were quick to respond and tweak things as required, and solved a number of issues that arose very quickly.

  • HOMETASTIC SOLUTIONStore build or redesignMar 6, 2025

    I have been working with Why Matter for many years and super happy with their work. They built 3 websites for us, including 2 eCom stores. Marcos always up for challenge, and we've never had any issues they wouldn't solved. What's very crucial for the startup like us, it's their affordable price range. I highly recommend this company!

  • HOLOS KombuchaTheme customizationJan 27, 2025

    We've now worked with the Why Matters team on several ocassions and they've been totally unphased and hard-working with every task thrown at them. Would highly recommended their services no matter how big or small the job is, they totally understand our every need.

  • West Chelsea MarketStore build or redesignSep 23, 2024

    Having worked as a creative director of several fashion brands, I decided to launch my own small collection. It didn't take long for me to realise I needed help to build my website, and therefore contacted several of the recommended Shopify experts. 'Why Matters' were the first to respond. Having had a conversation with the owner, I decided to go with them.... They didn't disappoint! Communication - excellent , technical ability - excellent, aesthetic understanding - excellent. The website/shop was built and launched on time and I am really happy with the result. I would not hesitate to recommend Why Matters, it was a pleasure to work with them. Plus I still have a 3 month period after completion to contact them with any queries.

  • geeAnalytics and trackingAug 1, 2024

    I'm really pleased with the quality and attention to detail in their work. They were quick to respond, and after two other developers attempted the same job, these guys got it done immediately and at a great price. I also appreciate the 3-month guarantee they offer with all their work - it really builds trust. Highly recommend!

  • Juno ClinicStore build or redesignJul 26, 2024

    I highly recommend Why Matters. This is the second time I have worked with them and I am planning to do so again. They are knowledgeable, creative, responsive, professional and hard working. I came across other overseas companies that were asking for £thousands up front that is a big risk for a small company. Why Matters is much more reasonable and did a fabulous job in building 2 websites for me.

  • crisskicksStore build or redesignJul 11, 2024

    It has been a pleasure working with the Why Matters team. We are a new business and needed a lot of guidance on all aspects of our site and e-commerce needs. Marcus allowed us to see our designs and ideas alongside recommendations to help guide us on our vision. No ask felt too big, and the revisions were done quickly. The project was delivered beyond expectations, and we continue to work with Why matters in the future!
