About Anna Sladkowski’s Current Company
Lumen Technologies

Hansen Technologies (ASX:HSN) is a global software and services provider to the energy, water/utilities and telecommunications industries. We have hundreds of customers using Hansen software in over 80 countries, supported by a collaborative and diverse team. For connection and collaboration, we have offices and development centres located in every continent except Antarctica. Within the communications industry, 5G represents the next new frontier for our customers – that unchartered territory to create opportunities and capitalise on new business models and resulting revenue streams. In the energy sector, we are in the midst of a transition. The move to renewables and self-generated energy changes the traditional commercial model. Today, our customers are no longer in the era of supplying basic commodity services - they are in era of providing new energy services and related experiences. We help our customers traverse these challenges and opportunities and realise the next new monetisable experiences. And that is why our mission is to provide industry-leading software and expertise, that enables our customers to capitalise on commercial opportunities while upholding the highest standards of data privacy, cybersecurity, sustainability, and ethical practices; and contributing positively to the communities we operate in. We make this possible by providing highly reliable, mission-critical software and specific industry expertise to help our customers more easily innovate and sell new services and market offerings, comply with changing market regulation, and power new business models in areas such as emerging sustainable energy supply, IoT, and new next-generation connected services. We aim to achieve this through long term collaboration with our customers and partners and through a global workforce of skilled professionals that embrace challenges and are committed to positive outcomes for our company, employees, customers, and the planet.
