Remember right before the election, when JetBlue promised Americans free flights out of the country if their candidate lost the election? It was a clever marketing stunt built around the cliched threats to move away if a certain candidate is elected. And the creative inspiration behind the campaign? Mullen.

The local advertising agency Mullen has been ranked 8th on AdAge’s prestigious A-List, the only Boston firm to make the top 10. Writes AdAge:

Mullen ended the year with a healthy 16% boost in revenue and a strong new-business track record that included Google creative assignments (including work for the new Nexus tablet and Play brand); creative for U.S. Cellular; creative for Grey Goose Vodka; media for National Geographic and public relations for Tropicana’s Trop50 brand. It’s also a dark horse in Honda‘s first review in more than 20 years, earning a spot as one of three finalists for the automaker’s account.

But more than any of those, the JetBlue campaign demonstrated the agency’s creative acumen, according to AdAge. And on the business side, Mullen’s success is due to diversification; they’re in just about every part of advertising, marketing, and PR.

With five U.S. offices and 680 employees, Mullen is a huge presence in the local media scene, and its success with JetBlue and others signals that its rise is likely to continue. Back in December, the company cracked Forbes’ Top 10 Agencies list, and in November, my colleague Lauren Landy wrote about what it’s like to work at Mullen. The gist was that the agency sees itself as constantly being in beta mode. So far, that seems to be working.
