Apsiyon is an internet start-up developed as SaaS intended to ease apartment and residence management while also serving as a closed social network for residents. It stands out among its rivals with features such as the integration of bookkeeping, monthly fee payments, staff follow-up, commercial agreements with third parties, meeting decisions, banks, e-state and e-municipality systems, dynamic websites for apartment or residences. Apsiyon started to be developed in 2010 to meet this demand in the sector and in June last year its beta version was released and currently there are more than 300 apartments that are actively using the website. Our aim is to reach as much apartments as possible in a short amount of time and to build a win-win based shopping infrastructure between the users in our system and companies.
