In 2017. Venture Capital Fund invested in Bulb to support the global expansion of CEMPRESSO and Bulb’s product range.

In 2020. we secured an investment thanks to a strategic partnership with M + Group, the largest independent BPTO service provider (Business Process and information technology outsourcing) in Central and Eastern Europe.

We are committed to continuously investing in our products and competencies.


As a member of the TM Forum, we are proud to have participated in Catalyst programs and received an award for Open AI Business Assurance Marketplace – Phase II. This Catalyst demonstrated how digital service providers can apply AI, machine learning, and API-based revenue assurance, credit management, and fraud management to effectively protect the digital business.
