Validating a new product in 30 days, so the expensive mistakes never got made

the brief.

Energizer, a global leader in battery innovation, was sitting on a new and experimental energy-storage concept in an unfamiliar product category. Before pouring money into full development, they needed to validate desirability and usability, accelerate the traditional innovation cycle with lean methods, and determine whether the prototype would resonate with real consumers.

the challenge.

Traditional product development would have spent months and a significant budget before anyone outside the building touched the concept. The challenge was to invert that: get a realistic prototype in front of real users quickly enough to make a confident go/no-go call, in a category where consumer expectations were unknown and the cost of guessing wrong was measured in R&D millions.

the process.

We ran a lean, iterative design sprint: rapid UX prototyping to simulate the product's interface and features, followed by real-world user testing to collect actionable feedback within a 30-day window. No internal politics, no committee: just a fast loop from concept to validated signal.

the solution.

a full-featured prototype, fast.

Rather than mockups, we produced a prototype real enough to test as if it were the product, then put it in front of target users. That fidelity is what made the feedback trustworthy: people reacted to something that behaved like the real thing, so the insights were the kind you can bet a roadmap on.

the outcome.

In 30 days, Energizer had data-backed direction on an unfamiliar product category: the ideal customer experience defined, and the go-to-market risk cut by validating product direction before full investment. The validation saved millions in R&D that the concept would otherwise have consumed on the way to the same answer.

Sometimes the most valuable result is a fast, early "no."
