About the Client
The client is an innovative sports startup determined to modernize how recreational spaces operate. Together, we developed a solution: a mobile-first ecosystem that introduces 24/7, fully autonomous table tennis venues to the Ukrainian market. Their vision was to provide players with instant, automated access to professional facilities, accessible entirely through a smartphone. Devtorium is proud to support entrepreneurs who leverage technology to make sports more accessible and scalable.

Challenges
The core objective was to replace manual venue management with a reliable, staff-free system. To make this work, our team had to solve several core challenges:
Building a fully autonomous ecosystem that integrates mobile software with physical venue hardware (smart locks, access control, video systems) while ensuring seamless synchronization.
Ensuring a secure, 24/7 operational environment that guarantees data protection and prevents unauthorized entry without human supervision.
Creating a user experience simple enough that first-time users could navigate booking, payment, and autonomous door access without on-site support.
Creating sophisticated analytics engines to process massive datasets and generate actionable insights through Tableau, Power BI, and AI/ML technologies.
Designing for scalability from day one to support multiple locations, increasing user traffic, and future feature expansion across iOS and Android.

FAQs
What problem does this platform solve?
Traditional table tennis venues require on-site staff, have fixed working hours, involve manual bookings, and offer limited transparency. It eliminates these friction points by creating fully autonomous venues accessible 24/7 via a mobile app, featuring smart access control, digital payments, and automated game tracking.
How long did the project take from start to launch?
We moved from initial development in November to a live, stable release by March 1st. This timeline allowed the client to open their first autonomous location on schedule, backed by a fully integrated booking and access control system.
What’s the market potential for this concept?
Autonomous sports venues represent a growing trend globally. By eliminating staff costs while providing 24/7 access, the business model is highly scalable. The Ukrainian market, specifically, lacks similar technology-driven sports facilities, positioning it as a first-mover with significant growth potential.
How does the platform ensure security without staff?
Multiple security layers protect the system: doors remain locked by default and open only for users with confirmed bookings and payments; all access events are logged; the system uses secure authentication; and any suspicious activity can be monitored remotely through the backend.
How does the autonomous access system work?
Users book a table through the mobile app and make a secure payment. The system automatically grants them access to the door shortly before their scheduled game time. At the venue, they simply open the app and tap to unlock the door. All communication among the app, the backend, and the door locks is encrypted and secure.
What makes the user experience different from a traditional club?
Beyond the convenience of 24/7 access, the platform digitizes the game itself. By integrating physical table buttons and automated video recording, players receive instant match statistics and video highlights directly on their phones
