The E-commerce CRM Consultancy.

Founded and built by Gymshark’s former Head of CRM, scaling the department as the business grew from £20m to £450m. Since then, we’ve worked with the likes of ASOS, Adanola, Represent and The Couture Club, unlocking their untapped potential.

Our approach is unequivocally customer-led. We map your data and customer experience to uncover the opportunities you're missing and the long-term wins worth building towards.

Every business, client, and brand is unique. That’s why we tailor our services to fit your brand and budget, delivering results that convert.

Trusted by the best.

    "Sarah has been incredible to work with, she hit the ground running and supported us exactly where needed. From an initial account audit to a loyalty migration and BAU support over peak - we have loved working with Sarah over the past 6 months, we would have been absolutely lost without her."


    Lily Thistlewood - Head of Digital Marketing

  • Represent Clothing.

    “Sarah has been instrumental in assisting us re-platforming onto our new CRM programme, Ometria, from Klaviyo, which was an absolute success. Sarah also has offered amazing guidance and support for all throughout the year – helping to implement a solid overall CRM strategy but also designing a very intuitive and highly engaging automation strategy which has done wonders for engagement. I would undoubtedly work with Sarah again."

    Ricky Jennings - Head of Ecommerce

  • Epetōme

    “Sarah wowed me from the start, with her exceptional project management, diligence and stellar execution to get Epetōme to launch. To work with an external agency/partner who is chasing YOU is rare and was extremely appreciated. No deadline slipped for CRM.”

    Chelsea Grosvenor-Hargreaves - Head of Growth

  • World of Books.

    “Working with Level Fifty Three has been an absolute pleasure. Their team quickly understood our challenges and worked collaboratively with us every step of the way. The quality of their work was outstanding, and the results speak for themselves—our email performance has seen significant improvements, driving real impact on our business. I was particularly impressed with their ability to not only deliver on our objectives but to uncover new opportunities we hadn't considered. Level Fifty Three's expertise and partnership have been invaluable, and I look forward to working with them again in the future.”

    Beccy Alford - Head of Marketing
