About Closed Loop, Inc

We're a paid media agency built on a simple belief: the agencies that consistently win aren't the ones that chase the newest tools — or the ones that ignore them. They're the ones with senior practitioners who know how to wield those tools at a level most teams never reach. That's what we've built at Closed Loop — and AI has made it more powerful than ever. Our team averages 12 years of paid media experience and four years of tenure here — in an industry where 18-month turnover is the norm. We've won Ad Age's Best Places to Work seven consecutive years, and our voluntary attrition is near zero. That stability shows up in the work: clients tell us we actually deliver what we promised in the sales process, keep the same team on the account, and treat their business as if it's our own. We work best with marketing leaders at mid-market and enterprise companies who are serious about growth and want senior expertise genuinely running their programs — not supervising them from a distance. Brands like Calendly, Calm, Clover, and Rakuten have trusted us to do exactly that. Founded in 2001. SOC 2 Type II certified. Headquarters in Northern California, with employees across the nation. If you're tired of agencies that overpromise and underdeliver, we'd welcome a conversation.
