Helping 7Days Earn Its Place in the U.S. Grocery Aisle

Client: 7Days US, a Mondelez Venture brand

Mission Field Lead: Julia Wing-Larson, COO

Client Lead: Allison Monette, Head of Commercial, 7Days US

Client Overview

7Days is a well-known cakes and pastries brand across Europe, with strong brand recognition and a loyal consumer base overseas.

Bringing that success to the U.S. market was never going to be a copy and paste exercise.

The U.S. Cakes and Pastries category is crowded, competitive, and heavily shaped by nostalgia. Shoppers have long-standing preferences. Retailers expect proof. New brands have to earn attention quickly or risk getting lost on the shelf.

As a Mondelez Venture brand, 7Days had the opportunity to test before scaling. The goal was to use that window wisely and come away with clear answers about what would work in the U.S. and why.

The Challenge

At the start of the project, the team was focused on one central question.

Could 7Days succeed in the Sweet Baked Goods category in U.S. grocery?

There were real unknowns behind that question.

·         Would U.S. shoppers try a brand without nostalgia on its side?

·         Would pack size and pricing meet expectations for everyday grocery trips?

·         Could the brand move beyond immediate consumption and succeed in multipack formats?

There were internal points of view. But the team knew real world data would be the deciding factor.

The Approach

Mission Field partnered with the 7Days team to design a test that allowed them to answer all of their key questions with a high level of confidence.

Pack size, pricing, and positioning were intentionally separated into separate test cells so results could be compared and inform the go to market strategy and how to best optimize.

“From the start, the goal was to bring discipline to the learning process,” said Julia Wing-Larson, COO of Mission Field. “We wanted data that leadership could trust and act on.”

This approach allowed the team to move quickly while maintaining the level of rigor required to support future investment decisions.

What Was Tested

The live retail test examined three primary variables.

·         Price Pack Architecture – 2 different multipack counts and product sizes were tested

·         Trade Effectiveness – 3 different price promo strategies were tested

·         Marketing  - shelf talk, Catalina, and demos were tested

Special attention was given to brand introduction. Demos, storytelling, and education were treated as core components of the test, not supporting tactics.

That decision changed the outcome.

What the Test Revealed

Once the test started, several insights became clear from both the in-store interviews the team did with actual shoppers and the sales data that was analyzed.

First, the package design was limiting sales because it was recessive on shelf and the brand name and other front of pack imagery didn’t communicate the value proposition clearly enough. An ROI analysis revealed which marketing levers were most effective in driving sales.

“The test reinforced the critical role of brand introduction and product demo in driving trial and repeat,” said Allison Monette, Head of Commercial for 7Days US.

Second, pricing and price pack architecture clarity emerged. The test provided actionable guidance on what pack size and price point should be carried forward with confidence.

Third, high category incrementality and a shopper base made up of a consumer segment that was important to the retailer helped build a strong sell in story to use when expanding distribution.

Impact on the Business

As 7Days transitions from the Mondelez Venture portfolio into broader integration, the learnings from this test continue to shape its U.S. strategy.

The team carried forward clear guidance on package design and branding, marketing, pricing, and pack architecture. Just as importantly, the data helped align internal teams and reduce debate.

Decisions moved faster because the market had already weighed in.

“The partnership worked because it had the rigor needed to invest big budgets behind the learnings, while still maintaining the nimbleness of a smaller company experience,” Monette said. “That flexibility mattered, especially when our European production did not arrive on schedule.”

Why This Partnership Worked

This project succeeded because testing was treated as a strategic step, not a formality.

·         Mission Field brought structure without slowing momentum.

·         The 7Days team stayed open to learning and adjusting in real time.

·         Together, the teams created a clear path from test to scale.

For brands entering new categories or new markets, that combination matters.
