Kaestria is a French software practice founded in June 2019 and based in Sainte-Suzanne, Réunion Island. Operating under NAF code 62.02A (IT systems and software consulting), we design, build, and run SaaS products focused on e-commerce productivity and SEO automation. RankingRider is Kaestria's flagship product line — an AI-powered SEO optimization toolkit available for Shopify, BigCommerce (soon), and Wix Studio merchants. The Wix version uses Google's Gemini AI to generate high-quality product titles, meta descriptions, long-form product descriptions, and focus keywords, then publishes them directly into Wix Stores via the V3 Catalog API on the merchant's explicit confirmation. Operating under French and EU law, Kaestria is committed to GDPR compliance, transparent data handling, and giving merchants full control over every change applied to their catalog. We do not sell, share, or use merchant data for training third-party models. Every optimization is generated on demand and published only when the merchant clicks "Publish".
