What Addenda Konverentsikeskus OÜ does

Addenda Konverentsikeskus OÜ (operating as Addenda) is a privately held Estonian professional training and continuing education provider headquartered in Tallinn, founded in 2011. The company delivers adult education across 14 vertical categories — construction, BIM, electrical, legal, labor law, accounting, public procurement, data protection, workplace safety, healthcare, social work, service/sales, and management/HR — to professionals and organizations in Estonia. It is registered in the Estonian Education Information System (EHIS) as an adult continuing education institution (notification number 209040), enabling it to award recognized continuing education credits (TP/academic hours) required for license renewal in regulated sectors.

The core product is the Addenda e-akadeemia, a 24/7 web-based learning platform (launched 2020) that provides asynchronous access to pre-recorded courses for one month after purchase, with downloadable materials and personalized certificates. This digital platform is complemented by open-enrollment in-person sessions held at modern conference facilities in Tallinn, custom on-site training (Tellimuskoolitused) for organizations, professional certification renewal programs (Kutse taastõendamine), a free training offering, and international study trips (Õppereisid). Course pricing is per-course, ranging from approximately 95 EUR (short courses) to 620 EUR (24-hour comprehensive courses), plus VAT, with payment terms of 7 days via bank transfer through payment processors Montonio Finance and Maksekeskus AS.

Revenue is generated primarily through one-time per-course fees covering materials and electronic certificates. The go-to-market is direct-to-consumer via the company website, email newsletters, SEO, and professional network referrals, with both individual professional buyers and organizational training buyers (construction, government, healthcare, education, professional services sectors). The company operates with 1–10 employees, holds a CreditInfo 2023 business certification, and is independently owned with no disclosed external investors or funding rounds. The only disclosed AI application is automatic generation of Russian-language subtitles for video courses, indicating limited AI integration.
