Clarity Project integrates open government data into user-friendly products with a focus on public procurement and register data integration, enabling government agencies and businesses to make informed decisions.  Clarity Project is a Ukrainian analytical online platform that provides access to more than 140 state registers, Prozorro procurement/auction analytics, and the Antimonopoly Committee's decision database and DASU monitoring. The platform has about 1,000,000 users per month, and the database contains about 37,000,000 files. The platform provides services for checking and monitoring contractors (individuals, legal entities, and local governments), Prozorro procurement and auction analytics, analysis of court cases, permits, licenses, and passports, as well as tools for increasing sales.  We believe that the history of the platform itself is a successful case study for a Ukrainian product company. In fact, over the years of its existence, the platform has evolved from a hobby of one of its founders to one of the main competitors and products based on open data in Ukraine. Throughout its existence, the platform has developed without attracting investment. In 2024 alone, the company's revenue grew 3. 5 times. Also in 2024, the company successfully developed an MVP version of its product for the Albanian Antimonopoly Committee.
