X-ONE is a software house based in Poznań, Poland with over 10 years of experience building custom digital products. The company works across web applications, e-commerce platforms, B2B and B2C systems, and AI-powered tools. A notable 73% of X-ONE's clients return for additional projects, suggesting sustained satisfaction with both deliverables and working relationship.

The firm's stated focus is on custom software tailored to specific business needs rather than forcing clients into off-the-shelf constraints. Their backend work relies on PHP (Symfony, Laravel) and Python, with frontends built using JavaScript, TypeScript, Vue.js, and Nuxt.js. For e-commerce they use Shopware; for rapid delivery they employ Webflow and Bubble. They integrate existing systems and specialize in low-code and no-code implementations.

Services and capabilities

X-ONE organizes its offerings around several categories. Their AI solutions include X-TALK, an in-house communication platform that handles voice, chat, and email through a single knowledge base. X-TALK operates 24/7, responding in under a second; it routes simple questions to AI agents and escalates complex issues to human staff with full conversation context. The platform also surfaces analytics on frequently asked questions and customer needs.

Dedicated software spans web applications, Progressive Web Apps (PWAs), B2B platforms, and B2C systems. The e-commerce division covers online stores, headless commerce, and composable commerce implementations. System integrations are offered alongside their low-code/no-code services. On the AI side specifically, they list data analysis, customer service automation, predictive maintenance for machinery, logistics optimization, marketing personalization, and risk management as application areas.

For custom AI, X-ONE emphasizes data control (no external sharing), systems designed to your specific workflows without bloat, and ongoing technical support with regular updates. They position dedicated AI against open-source solutions, citing transparency and data security as differentiators.

Notable work

Three named projects appear in their portfolio. VOX—described as a platform for offer creation and order management—was expanded into Mexico and additional markets as part of their global digital strategy. The CIO of VOX Capital Group noted the platform enables omnichannel consistency and that X-ONE's partnership was "essential" to reaching international customers.

Dailyfruits, a food logistics and production firm, had their warehouse, order fulfillment, and sales processes optimized through dedicated systems. A route optimization system and a KURIER courier app improved delivery operations; warehouse integration enhanced inventory management. One system raised order-picking efficiency by 150%. X-ONE's team introduced an intuitive subscription model that recalculates package counts per delivery, improving customer purchasing flow and inventory balance.

CasparLine, an investment management platform by Caspar, lets clients monitor portfolios and analyze markets via direct access to portfolio valuations and monthly/quarterly reports. X-ONE's understanding of both technology and Caspar's business needs was cited as key to the system's design.
