Case Study: O2 Slovakia achieves rapid self-service adoption and digital transformation with Liferay

A new self-care customer portal serving O2 Slovakia's fast-growing user base

O2 Slovakia, a challenger telecom launched in 2006, needed to reengineer its online presence to deliver simpler, faster customer service while integrating disparate internal systems, encouraging customers to adopt digital channels, scaling for growth, and recruiting developers. The company sought a single, scalable framework that would let both customers and frontline staff handle common transactions without shop visits or calls.

O2 chose Liferay in 2009 to build the responsive “My O2” self‑care portal, consolidating web content, authentication, SSO and role‑based access into one platform and bringing development in‑house. The portal drove major gains: logins rose ~20% month‑over‑month for a full year, customer self‑service and satisfaction improved, IT owns development, the platform now handles the vast majority of shop transactions, and it scaled with the user base from 0.5M to nearly 2M.
