Our values

01

Integrity

We manage a relationship, not a transaction. We tell a client what we know, not what they would like to hear.

02

Confidentiality

A closed process, an anonymous teaser, a signed NDA. Only the people who need to know that a sale is being discussed know it.

03

Precision

Every figure has a source and every document an owner. We answer the question a buyer will ask before they ask it.

Globalscope Partners

When your buyer is abroad, a member firm in its country works with us.

Orion is a member of Globalscope Partners, founded in 1987, which brings together independent M&A advisers around the world.

When the right buyer for a Turkish company is abroad, we work with the Globalscope member firm in that market; and the same for a buyer coming to Turkey from abroad.
