The agency is platform-specialised on Shopify and Adobe Commerce (Magento), holding Adobe Gold Certified Partner, Shopify Partner and Google Marketing Platform certifications, and has assembled a partner ecosystem (Nosto for AI personalisation, Reviews.io for review management, Mida.so for A/B testing, Dotdigital for email automation, Gorgias for customer service) that it resells and integrates into client engagements. Pricing is bespoke and not publicly disclosed; revenue is generated through professional services retainers and project-based fees, with bespoke quotes issued after consultation.
