Apttus, a San Mateo-based software company that offers a platform for companies to automate and optimize revenue, has announced that a former Kirkland & Ellis corporate partner is its new chief legal officer.

Omer Rafatullah.

Omer Rafatullah started as the top lawyer at the software company in the beginning of December, according to his LinkedIn profile. It was not immediately clear if he is the company’s first CLO or if he replaced someone. An email to a company spokesperson seeking further comment was not returned Monday.
