Sintra - Digital Business. Poland

Sintra is a Poland-based software and e-commerce development firm founded in the early 2010s (exact year not specified). The company works with international clients across North America, Europe, and Asia—names like Vegamour, Eleo Zaun, Allies of Skin, and Balsamique appear in their portfolio. They describe themselves as "a team of creatives, developers, and managers" but don't publish headcount. Their work spans custom software, e-commerce platforms, and design-led product development. On Clutch, they maintain a Net Promoter Score of 82.

Services and capabilities

Sintra organizes its offerings into three pillars: ideation and design, e-commerce development, and custom software. On the design side, they emphasize data-driven problem solving and accessible interfaces. Their e-commerce work centers on Shopify Plus, Magento, and WooCommerce. They've handled migrations (Magento to Shopify for Allies of Skin), platform optimization, and ongoing maintenance for high-volume stores.

For custom development, they work across React, Node.js, WordPress, and hybrid tech stacks. The Eleo Zaun project illustrates their approach: they built a React-based product configurator for customized garden fences, bridged it with Magento's backend, and layered WordPress for content management. They also handle performance tuning—for Eleo they optimized page loading, adjusted CSS for Core Web Vitals, converted images to WebP/SVG, and fixed iOS compatibility issues.

Vegamour's Shopify Plus store shows sustained engagement: Sintra runs a dedicated team handling subscriptions, checkout logic, automated testing (hourly cart and checkout verification), and scaling across international markets. The store processes over 100,000 orders per month.

Notable work

Vegamour is Sintra's largest visible client engagement. It's an all-natural, vegan hair wellness brand operating at scale on Shopify Plus with international reach. Sintra's team manages a dedicated squad that handles consultation, feature development (subscriptions), monitoring, and multi-market expansion. Their work spans discovery (auditing the existing platform), development (major site revamp and new design), and ongoing maintenance.

Eleo Zaun (fences and garden pavilions, Germany and Austria) required Sintra to architect three parallel technical stacks—Magento for e-commerce, React for a product configurator, WordPress for content pages. They solved the challenge of bridging React to Magento's database so customer configuration data synced transparently. The result was faster load times and configurator responsiveness across devices.

Other named projects include Allies of Skin (lossless Magento-to-Shopify migration), Ombrelab (described only as "the future of self-care"), Balsamique (launching an online channel for a beauty brand), and Schmiede24 (Shopify migration and theme customization). Most clients operate in beauty, wellness, or home and garden sectors.

How they work

Sintra's engagement process follows a four-phase structure: evaluation (scope discussion), discovery (competitive analysis and strategy), ideation and design (high-fidelity mockups and UX standards), and execution (building to spec). For Vegamour, they deployed a dedicated development team with daily standups, QA testers, and a manager. For Eleo, they organized three parallel teams across different tech stacks and merged pre-launch.

They respond to inquiries within 24-48 work hours. Pricing is not published; estimates are offered on request. The company values flexible work arrangements internally but expects responsibility and on-time delivery.

Team and credentials

Sintra does not publish team size, founder names, or office locations on the public site. They list no formal certifications (ISO, SOC 2, etc.). Their strongest credential is the Clutch Net Promoter Score of 82. Client testimonials are brief: Allies of Skin notes "quality and timely work," Ombrelab highlights how Sintra "empowered internal stakeholders to use our Shopify store," Eleo GMBH references "agile development" and continuous learning together. Alba Thyment describes them as "knowledgeable, communicative, professional and honest."
