Coway turned Malaysians' dreams into data and sold $8 million of sleep products
A dream-visualizing website disguised a sleep survey as art; 5,278 dreams came in and 83% of dreamers bought a Coway product.
Coway Malaysia
The solution
A 2021 survey found nine out of ten Malaysians reported insomnia, a nationwide need Coway — known for water and air purifiers — had no natural claim on. The brand wanted to enter sleep and rest, but a conventional sleep survey would be invasive and ignored.
Grey Malaysia's solution reframed data collection as an experience: users submitted their dreams and received personalised works of art visualising them. Embedded in the submission flow were questions about pre-sleep routine, so every artwork doubled as a research response.
The campaign was effective as well as elegant. Of 5,278 dreams submitted, 4,379 people bought a Coway product — an 83% conversion — generating over USD 8 million in sales. It won the Innovations Kancil at the 2023 Kancil Awards, a Bronze at Cannes Lions 2024, and was praised as 'data collection done elegantly and subtly'.
Why it worked
- The dream-art framing made sharing intimate data feel like a treat, not a survey
- Every submission carried structured signals about habits, enabling genuinely personalised recommendations
- It positioned Coway as a sleep and rest expert instead of a white-goods maker
- The campaign itself generated earned coverage, multiplying its reach beyond the media spend
What can be applied
When the data you need is private or boring, make the collection itself the value; people will volunteer far richer information for an experience they want than for a form.
Aftermath
Coway Malaysia was named Advertiser of the Year at the Kancil Awards 2023 on the back of the work, and Grey Malaysia took Agency of the Year. The campaign went on to win a Bronze at Cannes Lions 2024 and became a frequently cited example of subtle, experience-first data collection; the $8 million in sales during the campaign period made it one of the Malaysian market's most-quoted effectiveness stories.
