Heseya - Enhanced e-commerce platform

Based in Warsaw, Heseya builds and maintains an open-source headless eCommerce platform aimed at online store owners looking to scale their operations. The company works with businesses that already run a store but are unsatisfied with their current setup, offering migration from other platforms, as well as with merchants starting new projects that require a flexible, integration-ready foundation. The team size is small, between one and ten people, and the agency positions its platform's source code as publicly available on GitHub. The core offering centers on a headless eCommerce architecture that separates the storefront from backend logic, allowing the same shopping experience to be delivered consistently across multiple sales channels and devices, including mobile. Heseya emphasizes site loading speed as a factor tied directly to search engine positioning and describes built-in SEO tools and a search-engine-friendly site structure as part of the platform. The company also lists numerous integrations with payment systems, sales systems, and comparison shopping engines to support the checkout and sales path. Additional described capabilities include access to customer behavior data for optimizing sales and reducing cart abandonment, promotion and up-selling functionality intended to encourage repeat purchases, and one-click data migration for stores moving from another platform. Declared service areas include SEO, e-commerce development, and mobile app development.
