Lior Tencher
Founder & CTO
Lead technique Full Stack — plus de 12 ans d’expérience dans la création de systèmes logiciels évolutifs en cybersécurité, fintech et SaaS.
Lior joined his father's project after seeing the depth of data and analysis assembled over a decade and recognizing that it deserved a real platform — not a private spreadsheet.
His first task was rebuilding the entire statistical engine from scratch. The original models were accurate but not built for scale or speed. Lior redesigned the architecture to handle real-time data ingestion, automatic recalculation after each draw, and the kind of query volume that comes with a public platform serving thousands of players. That engine — the infrastructure that makes Lottorios fast and accurate — is entirely Lior's work.
Lior also built the real-time draw results pipeline: the system that pulls official results from lottery operator sources and triggers the full suite of statistical recalculations automatically. Before that pipeline existed, updates were manual. Manual entry means errors. Lior's goal was to remove the human step entirely and let verified source data flow directly into the platform.
Beyond the technical infrastructure, Lior focuses on how statistical information is presented. Complex probability outputs are only useful if players can understand them. He designs the interfaces, the data visualizations, and the explanatory copy that translate years of research into something a first-time lottery player can immediately use.
