We keep focus on understanding the needs of our clients and fulfilling them with top quality software products and professional services.

Let's get to know each other

Bulb Technologies is a software company focused on the digitalization of customer support and customer engagement through self-service applications. For years, we have been delivering business automation software solutions to automate and improve business processes through the use of advanced technologies.

Who are we?

Bulb Technologies was founded in 2006. in Zagreb and has been supporting digital transformations in large enterprises ever since.

Today we have more than 70 employees in Bulb, most of them engineers. Our strength is the excellent telco domain knowledge and system integration skills.

It is very significant to point out that we have secured two rounds of funding. 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 and Asia Minor.

We are committed to continuously invest 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.



What do we do?

Based on years of experience and proven capabilities to deliver complicated CEM projects, Bulb Technologies has developed the Cempresso CEM product suite.

We believe that Cempresso is definitely the only platform for customer support digitalization that a company needs. Moreover, our solutions cover the entire interaction lifecycle (from contact center to issue resolution) and enable:

  • Cross-functional process improvement and automation,
  • Digitalization and omnichannel adoption,
  • Process optimization and orchestration.

Our portfolio enables organizations to achieve various benefits such as higher productivity and cost reduction, greater accuracy, improved customer experience, higher employee satisfaction and revenue, and improved operational excellence.

Over the past 15 years, Bulb Technologies has earned a reputation as a leader in broadband service management.
The company has helped communications service providers – fixed, cable, and mobile – deliver a superior customer experience while dramatically reducing operating costs. Bulb Technologies has served more than forty clients across Europe, including operators of Deutsche Telekom, A1 Telekom Austria, Telecom Italia TIM, and United groups.

Bulb’s state-of-the-art solutions for service assurance, customer experience management (CEM), device management, and service analytics rival those of the largest global software vendors.
Bulb’s Cempresso Suite is a next-generation solution that offers a new approach to automated end-to-end diagnostics, guided troubleshooting, and analytics. Built on a comprehensive automation framework, Cempresso provides step-by-step guidance for customer service representatives and empowers end customers to troubleshoot issues themselves via a self-care interface on their smartphones.
