Waiākea Hawaiian Volcanic Beverages has added three professional athletes to its investor and impact partner roster: Carolina Panthers rookie wide receiver Tetairoa McMillan, New York Mets pitcher Devin Williams and Portland Trail Blazers forward Jerami Grant.

A company spokesperson told Refreshment that the latest round raised $11 million in total, with McMillan, Williams and Grant contributing alongside other investors. Individual investment amounts were not disclosed.

Waiākea said the partnerships reflect a shared focus on purpose-led business and environmental stewardship, aligned with the company’s sustainability positioning and B Corp certification. The athletes join the brand as both investors and advocates for its social and environmental initiatives.

The trio joins Waiākea’s existing group of athlete partners, which includes Aaron Judge, Myles Garrett, Klay Thompson and several Hawai‘i-born professional athletes across baseball, football, surfing and volleyball.

Ryan Emmons, co-founder and chief executive of Waiākea, said the company was “working with impact leaders who truly believe in our mission and community impact.”

McMillan said investing in Waiākea “puts culture and purpose first,” while Williams described the brand as “something special” he was proud to support. Grant added that Waiākea’s focus on family, philanthropy and environmental care made it “the perfect partner.”

In October, Refreshment interviewed Waiākea co-founder and CEO Ryan Emmons, discussing the company’s approach to tackling packaging sustainability challenges and its wider environmental commitments.
