Agency
Big Day the Agency is a San Diego advertising and creative agency that helps brands defy ordinary. Founded here in 2021, we bring strategy, branding, design, campaigns, production, and social media together around the moments that matter to a business. We work with ambitious local companies and national brands that need ideas people will notice, remember, and act on.
San Diego Roots and Work That Travels
We are proud to call San Diego home. Our team has built campaigns, identities, and experiences for brands across the country, with the same care for a local launch as a national assignment. What matters is the opportunity: a crowded category, a pivotal product, or a brand whose creative needs to work harder.
Clutch has named Big Day among its best-performing advertising agencies in San Diego. Our work has earned seven One Club San Diego awards: three Gold, two Silver, one Bronze, and Best in Show for Casper’s “Dream Machine” commercial. The recognized work also included Guru, Royal Caribbean Group, and HexClad.
What We Do
Brand and marketing strategy. Research, audience insight, competitive analysis, positioning, and messaging that give the creative a clear job.
Branding and identity. Naming, visual identity, voice, guidelines, and systems built to show up consistently.
Advertising campaigns. Ideas and executions for out-of-home, digital, social, video, broadcast, and connected TV.
Creative design. Packaging, digital experiences, event and trade show materials, and the everyday touchpoints that shape perception.
Production. Commercials, brand films, photography, animation, CGI, and content in the formats each channel needs.
Social media. Channel planning, content creation, calendars, and campaigns that connect ongoing conversation to launches and live moments.
Why Defy Ordinary
Ordinary creative can be expensive: media dollars behind an ad no one notices, a message that fails to stick, and another strategy reset to make up for it. We look for the white space a brand can credibly own, then turn that thinking into work with enough clarity and character to break through. The ambition is creative that earns attention and helps the investment work harder.
Who We Work With
Our work includes Casper, HexClad, Royal Caribbean Group, Guru, Super 8, Earth Rated, Luna Grill, The Kebab Shop, and the BNP Paribas Open. The category and scale may change, but the assignment is familiar: understand what makes the brand matter and express it in a way people cannot mistake for anyone else.
We work with consumer and B2B brands, including teams in food and beverage, home goods, travel and hospitality, technology, sports, and events. A San Diego business looking to grow beyond the region and a national company seeking a more distinctive campaign both deserve senior thinking and strong execution.
How We Work
The right team and scope depend on the brief. We begin with the business problem and the audience, define what success looks like, and build a plan for the work. Our BD Process keeps clients involved and informed as decisions, budgets, and schedules evolve. We value direct collaboration, transparent communication, and creative that can hold up across real channels and formats.
