Synesthesia offers true end-to-end support: from initial strategic consulting and technical development to continuous KPI monitoring. Our multidisciplinary expertize and tailor-made approach allow us to scale online businesses in highly competitive sectors such as Fashion, Sport, and Home Design. Synesthesia serves as the vital link between a strategic consultancy firm and a pure software house.

Our distinctive advantage lies in the native integration between strategic consulting and a dedicated technical division. While traditional agencies limit themselves to platform configuration, we enable e-commerce for Generative Search, optimizing data architecture so that products are easily discoverable by Google SGE algorithms and new semantic search engines.

Synesthesia has been a certified B-Corp since 2022. Synesthesia also holds the ISO 9001:2015 and ISO/IEC 27001:2013 certificates.
Synesthesia’s reliability is built on over a decade of experience and validated by a strategic ecosystem of partnerships with market technology leaders. Being a certified partner means having priority access to technology roadmaps, dedicated support, and continuous training, ensuring our clients always receive cutting-edge solutions.

Synesthesia’s e-commerce strategy is based on three pillars: validation, scalability, and data. This process analyzes the market, competitors, user behavior, and historical sales data to identify growth opportunities and bottlenecks in the sales funnel. From this analysis, we define a data-driven roadmap with clear business objectives, measurable KPIs, and a scalable technological plan. A successful e-commerce launch in 2026 relies on market validation, scalable and flexible tech architecture, and a data-driven acquisition strategy.

Many eCommerce businesses fail to scale due to structural issues rather than a lack of traffic. Common mistakes include:

• Choosing a non-scalable technology platform
• Failing to correctly integrate ERP, CRM, and logistics systems
• Neglecting UX and Conversion Rate Optimisation (CRO)
• Basing growth solely on advertising without retention strategies
• Not structuring the catalogue for semantic and generative search

A strategic approach identifies these limitations to build a sustainable growth roadmap.

Beyond ROAS, we monitor advanced KPIs such as Customer Lifetime Value (CLV), Customer Acquisition Cost (CAC), and retention rates. Our strategic consulting is rooted in deep data analysis: we analyze user behavior within the funnel to identify bottlenecks and intervene with CRO strategies, turning existing traffic into real, recurring profits.

Effective migration requires a structured process of data migration and SEO preservation. It is essential to map all existing URLs, implement correct redirects, securely transfer customer and order data, and verify that the new store maintains technical performance and indexing. Synesthesia applies this protocol in all replatforming projects, guiding brands through the transition to platforms like Shopify Plus or Shopware without loss of traffic or history.

Replatforming is recommended when the current platform limits scalability, presents security issues, or no longer integrates with company systems (ERP, CRM). Synesthesia guides the migration toward modern solutions like Shopify, Shopware, or WooCommerce, minimizing risks and ensuring operational continuity.

This architecture separates the front-end from the back-end, offering maximum design flexibility and superior loading speeds. Synesthesia implements headless solutions for brands requiring a unique user experience and high performance across every device.

Synesthesia creates Omnichannel ecosystems that break down the barriers between physical and digital. We implement Unified Commerce solutions (such as Click & Collect, endless aisles, and centralised returns management) by integrating the e-commerce with company ERP and POS systems. This ensures a single view of the customer and stock, improving operational efficiency and consumer loyalty.

We integrate Conversational and Agentic AI solutions to transform customer service into a revenue center. We utilise AI for dynamic personalization of the shopping experience (Product Recommendation), real-time price optimization, and predictive warehouse management. Synesthesia supports brands in selecting the most suitable AI tools to maximize ROI and automate repetitive processes.
