Pure spirulina and natural superfoods from Hawaii

Pure spirulina and natural superfoods from Hawaii

Nutrex Hawaii is the world's leading producer of Hawaiian Spirulina, grown in Kona, Hawaii using natural deep ocean water. Their premium positioning and unique origin story were strong brand assets — but the website was not translating that story into conversion for new visitors.

The challenge

Why Nutrex Hawaii partnered with us

Why Nutrex Hawaii partnered with us

Spirulina buyers are health-conscious and research-oriented. Nutrex Hawaii needed to communicate what makes Hawaiian spirulina different — and why it's worth a premium — to an audience that had many lower-cost alternatives.

1

User Experience

The product story — Hawaiian origin, deep ocean water, sustainable harvesting — was buried below the fold on PDPs, leaving new visitors without the differentiation they needed to justify the premium price.

2

Experimentation

No systematic testing. Design decisions made without conversion validation.

3

Capabilities

Small team needed a full-service CRO partner to run experiments across the funnel.

4

Strategic Growth

Grow subscription revenue to build predictable recurring revenue alongside one-time purchases.
