High-profile venture firm Sequoia Capital has appointed Admob‘s founder Omar Hamoui as its newest partner.

Hamoui also founded startup accelerator Churn Labs, which was shut down in May 2012 after the entrepreneurs left for various startup jobs.

Hamoui sold his most recently company, a social polling startup called Maybe Inc., to LinkedIn. While building Maybe, he also made some strategic investments in early-stage startups such as Gigwalk and
