Fortnight Collective has been working with Yasso Frozen Greek Yogurt for a year-and-a-half, and in that time it has helped build the company’s brand strategy, creative development, packaging and website. The short timeline of collaboration was even more condensed for the brand’s latest effort – new holiday flavor packaging.Fortnight Collective, based in both Boulder, Colorado, and London, collaborated with Yasso on brand strategy, creative development and creative refinement, and the work was all was done across a three-day ‘BrandSprint’ in Boulder. This technique, which Fortnight calls “swift and efficient” is where ad campaigns and rebranding strategies can be accomplished in as quickly as three days or under two weeks, which the agency says suits the current, ever-changing market.Yasso has now unveiled three new flavors for the fall and winter holidays – Pumpkin Cheesecake, Peppermint Crunch, and Sugar Cookie – the first seasonal lineup for the seven-year-old brand. Available in both bars and pints, the limited-edition flavors are in addition to Yasso’s current offering of 24 different flavors. Fortnight and Yasso wanted to reflect the joy Yasso yogurt products bring to its customers, so the packaging for the holiday flavors features spirited, colorful characters enjoying Yasso treats. Designed by Fortnight Collective, the snowman, smiling pumpkin, and Mrs. Claus on the packaging was designed to stand out in the freezer.CreditsAgency: Fortnight CollectiveBrand: Yasso Frozen Greek Yogurt
