Direct to the CEO.
Write what you need to say. It goes to Mehadi Hasan Farhad, CEO and no one else. Every message is read.
We do not ask for your name, your email or your employee ID, and we do not record your IP address or your device. Nothing saved with your message points back to you.
What you write is up to you. If you describe something only a few people know about, that detail can identify you on its own.
