Who We Are
There's a moment when a business stops wondering whether social media matters and starts asking what it's actually going to take. The budget is real. The goals are clear. What's missing is the right partner. You need a partner with the experience, the technology and the strategic depth to build something that’s proven to work.
That's the conversation we're built for.
A Bigger Room is a full-service social media marketing agency based in San Francisco, founded by Shannon Greevy, a social media strategist with nearly two decades of experience building programs for some of the world's most recognized brands.
We work with businesses that are ready to invest in doing this right: companies with serious clear growth ambitions and the sophistication to know that results require real strategy. We're selective about who we work with because the best client relationships are built on genuine fit, shared expectations and mutual respect.

From there, she moved to a luxury startup, NUDE Skincare, incubated within Benefit Cosmetics for LVMH, managing global social and digital marketing.
At BBDO she lead social media for the Wells Fargo small business and commercial banking account, After a promotion into communication strategy, she applied deep social media expertise to large-scale creative work for Wells Fargo, Mattel (Barbie and Fisher Price) and Mars Pet brands (Crave, Nutro).

Work that belongs to your business.
We build your infrastructure, your accounts and your data so that they're yours fully and permanently. You're investing in an asset, not a dependency.
A relationship worth having.
