The marketer who built a better way to launch ads.
A decade scaling campaigns. Millions in ad spend. Now building the tools he wished he’d had.
Cedric Yarish is a Meta ads expert, performance marketer and co-founder of AdManage.ai. He combines a decade of hands-on media buying with the skills of a software builder. After leading growth campaigns at Photoroom, Nextdoor and MVF, he co-founded AdManage.ai with his brother Raphael to give marketers more time for the work that moves their business forward.

Before AdManage
The story
Cedric’s experience spans the full journey from making the creative to measuring the result. At MVF, he helped scale YouTube advertising from zero to £300,000 in monthly spend, managed a five-person video team and produced more than 100 ads that reached over 30 million views. His work also took him into native advertising across more than 40 countries, app development and conversion optimisation.
At Nextdoor, he managed international user acquisition across seven markets, from Europe to Australia and Canada. He launched and optimised iOS 14 Facebook campaigns, helping reduce overall costs by 30%, while building automated reporting and testing new acquisition channels.
As User Acquisition Lead at Photoroom, he managed a marketing operation spending more than $1 million a month across Meta, TikTok, Google and Apple. His team produced 400 creatives a month in 30 languages, pairing rapid experimentation with automated reporting and ad workflows. It was an education in what a small, technically capable team can achieve at scale.
Those experiences became the foundation for AdManage. Today, Cedric leads its product and engineering, turning the daily frustrations of media buying into practical software. The platform has helped 1,300+ teams launch 7.7M+ ads, with creative research, reporting and automation alongside the launch workflow.
His approach is simple: understand why people buy, make better creative, and build systems that let good teams move faster. He shares that thinking through product tutorials, interviews and practical writing for marketers.
