Quollio Technologies creates products that enable Enterprise Data Intelligence.

In this realm, Quollio aims to platformize essential information required for organizational decision-making and operational data utilization, starting from metadata management to overseeing data presence and flow across departments.

A pivotal aspect of Quollio's products lies in the concept of abstraction. From handling metadata, which represents data about data, to conceptualizing practices and behaviors in data analysis and engineering, and even abstracting individuals and organizations for promoting Data Intelligence in large enterprises through user interface/user experience (UI/UX) design, Quollio pioneers novel concepts in data utilization within their products. By offering these functionalities in a user-friendly manner, Quollio ensures that their solutions stand out as unparalleled in the realm of Enterprise Data Intelligence.

With the recent Series A funding, Quollio embarks on a journey to foster further growth both within the company and their products. Consequently, they are seeking new development team members who are eager to contribute to this shared vision of growth and innovation.
