How do you build a brand equipped for today's marketplace—one that actively evolves with customers, as attention spans are short and channels are many? Yes, it may start in the C-suite, but true brand engagement happens every step of the way, by reaching customers at the very moments they're likely to make decisions. No one understands this better than Sullivan. That's why, for more than 20 years, many of the world's top companies have entrusted us to cohesively build their brands by connecting with their customers and audiences at the right moments, across the right channels—and drive measurable results for their business.


success stories



At a time of great organizational change for WebMD, Sullivan reimagined the company's brand story and executed it across multiple channels for WebMD's first-ever integrated campaign. Building off the unique sense of focus and follow-through that define WebMD users, Sullivan's work contributed to advertising sales reaching 8% above analyst projections in a recent quarter.


As the world's leading institutional equities marketplace, Liquidnet transformed an industry in 10 years; yet rapid growth left its story muddled. By capturing Liquidnet's unique marriage of scale and reliability, Sullivan rethought the company's identity and creative platform, and activated the new positioning across all channels. New website pageviews have increased 15%, and the average time a user spends on the site has risen 240%.

Duke University

Sullivan developed the university's "Duke Forward" campaign identity and execution to reach all audiences—not just traditional high-networth contributors. Our platform and identity present a more empowered Duke, and the campaign's homepage engages all donors by integrating social media to generate a real-time feed for the campaign. Duke Forward is on pace to exceed its fundraising goal by 22%.
