Theorem Team

Theorem Team is a certified Shopify agency focused on helping ecommerce and DTC brands build better stores, improve conversion rates, and grow revenue. We specialize in Shopify design and development, conversion rate optimization (CRO), UX/UI, Replo landing pages, retention marketing, Klaviyo email marketing, SEO, analytics, and custom Shopify solutions. Our work sits at the intersection of strategy, design, technology, and measurable growth. Our team works with brands at different stages, from businesses launching or rebuilding their Shopify store to established DTC brands looking to improve conversion rates, customer experience, and retention. Our core capabilities include Shopify store design and development, Shopify theme customization, CRO audits and optimization, high-converting landing pages, product and collection page optimization, checkout and customer journey improvements, Replo development, Klaviyo flows and campaigns, ecommerce SEO, analytics implementation, and custom Shopify app development. We use a modern ecommerce technology stack including Shopify, Shopify Liquid, Replo, Klaviyo, React, Next.js, Tailwind CSS, Supabase, Google Analytics 4, and major paid media platforms. We are particularly interested in projects where we can have a measurable impact on the business, whether that means increasing conversion rate, improving average order value, strengthening retention, reducing friction in the buying journey, or creating a stronger foundation for scalable growth. Our philosophy is simple: traffic alone does not create a successful ecommerce business. The store experience, offer, customer journey, and retention system all need to work together. We combine data-driven analysis with strong design and technical execution to create Shopify experiences built for growth. Theorem Team is built to be more than a development vendor. We aim to become a strategic ecommerce partner that understands the commercial goal behind every project and builds toward measurable outcomes.
