What TSEK does

TSEK is the digital business information platform operated by Banking Information Systems S.A. (Tiresias S.A.), Greece's sole Credit Bureau. The platform, launched in 2014, provides online access to Tiresias's 30+ year proprietary database of financial behavior records — including bounced cheques, bills of exchange, payment orders, bankruptcies, mortgages, and seizures — sourced from the Default Financial Obligation System (DFO) and Mortgages/Prenotations System (MPS) and updated daily. Core products include the TSEK Platform (web self-service), TSEK Bi (a probability-of-default statistical model on a 1–9 scale with a 12-month forward look built on published balance sheet data), Alerts (automated company monitoring), Business Reports (Basic and Detailed), International Reports (covering 89 countries via the Creditreform partnership), and four API services (Instant Credit ID, Balance Sheet Flex, Fast TSEK, TSEK App) for enterprise system integration. In 2026, the company extended its offering with Tiresias Services Powered by Equifax, adding AI-driven identity verification and cyberfraud prevention services.

The business model is a multi-channel digital SaaS platform. TSEK sells annual subscription packages tiered by search volume — €375/year (100 searches), €680 (200), €1,100 (350), and €1,520 (500) — each bundling access to Tiresias Data, Financial Data, Alerts, Business Reports, Instant Credit ID, TSEK Bi, and International Reports. On-demand usage-based flexible packages complement subscriptions. API services, International Credit Reports (transaction-fee), and the new Equifax-powered fraud services represent additional revenue streams targeting medium and large enterprises. The company employs ~6 staff (per firmographic input), suggesting a technology-leveraged operating model, and reports 3,000+ Greek business customers, supported by ISO 9001:2015 certification and GDPR-compliant data processing. Leadership includes Chairman Dr. Solomon Berahas, CEO Mr. Ilias Xirouhakis, General Manager Dr. Petros Kapasouris, and Commercial Director Mr. Ioannis Paloglou.
