Strategy + Marketing + Advertising + Startups + Smart = Me The writings, ramblings and insightful observations of Sean Bohan. I have deep experience with boutiques, large agencies (Advertising, Digital, Media, Direct and PR), and startups (digital, consumer, B2B). In the past 16 years I have gone from being the âtroubleshooterâ to the founder of my own agency where the work included strategy, startup product design, marketing, documentary films, live events, mobile, social and web.
