Nina Oden

Nina Oden has 25 years of experience in developing brands. She spent the first 15 years of her career within Unilever, leading brand positioning, innovation and communication on global brands such as Persil, Comfort and Cif.


Working as a consultant with Entropy lets her focus on what she most enjoys: helping others think and do marketing better, through helping define briefs to business and marketing issues, designing and leading workshops and providing brand planning consultancy. She has also spent a large part of her time developing marketing frameworks and designing and leading large training programmes for Unilever.


Nina sees her role as unlocking new insights and providing clear direction by encouraging expansive thinking and always challenging the team to think and act beyond the obvious, well-trodden path. Her approach is to collaborate closely with the client team, other experts and companies to create the strongest team and delivery for every project, thereby keeping approaches and solutions fresh, nimble and fit-for–for-purpose.
