Doğa Schools, or Arı İnovasyon ve Bilim Eğitim Hizmetleri Anonim Şirketi, is a chain of private educational institutions in Turkey that offers education from kindergarten through high school.

Şimsek had a background in running chains of preparatory schools for high school and university entrance exams, and English Time, a chain of English language courses.

[2] In 2019, the teachers in several different Doğa Schools protested because upper management had delayed paying their salaries one to five months.

As a result, in 2020 Istanbul Technical University bought the chain for 12 million TL.

The chain was later purchased by Can Education Group, which also owns the private Istanbul Bilgi University, in 2022.
