Coolmate secures Series C funding, marking a new growth chapter for a Vietnamese brand

Hanoi, November 3rd, 2025 

Coolmate, Vietnam’s pioneering D2C fashion brand, announced the completion of its Series C funding round led by Vertex Growth Fund, with participation from Cool Japan Fund, YoungOne CVC, and existing investors Vertex Ventures SEA & India and Kairous Capital. Vertex Growth Fund is a growth-stage venture capital fund anchored by Vertex Holdings, a subsidiary of global investment firm Temasek; Cool Japan Fund is a government-backed investment fund from Japan; and YoungOne CVC is the corporate venture arm of Youngone — one of the leading global manufacturers in sports and outdoor apparel. 

The participation of world-class investors and the continued support from existing shareholders is a strong vote of confidence in Coolmate’s execution capability and long-term commitment to sustainable growth, despite a highly dynamic investment landscape in Vietnam. 

“Made in Vietnam for the World” — A New Chapter Begins 

Founded in 2019 on a D2C business model, Coolmate has built an optimized technology-enabled local supply chain to deliver high-quality products at accessible

prices with exceptional customer service. Over the past 6 years, more than 5 million orders have been delivered across Vietnam — demonstrating the true value that a young Vietnamese brand can create. 

Entering the 2026–2030 horizon, this Series C round accelerates Coolmate’s three strategic priorities: Go Women – Go Global – Go Offline. 

Go Women — Unlocking the Next Growth Segment 

In March 2025, Coolmate officially launched its women’s activewear line — one of the fastest-growing apparel categories in Vietnam. The initiative expands Coolmate beyond “a men’s brand” to become “a performance lifestyle brand for all,” with a target of achieving 40% of total revenue from Women Active by 2030. 

Go Global — From First Wins to Long-Term Vision 

In 2025, Coolmate made its debut on Amazon US with a sports sock product line that quickly reached Best Seller status, surpassing 25,000 orders per month within just a few months. This success lays the foundation for regional expansion across Southeast Asia and the goal of 30% international revenue by 2030. 

Go Offline — Building Performance Lifestyle Destinations 

Coolmate’s offline retail strategy enables customers to experience the essence of Vietnamese quality through purposeful design, functional performance and meticulous attention to detail. Offline retail will become a critical growth pillar, contributing 40% of revenue by 2030. 

A Strong Foundation That Earns Global Investor Confidence 

Amid volatile startup conditions, Coolmate stays committed to real value creation through four strategic strengths: 

• Vietnam-based supply chain excellence 

• Capability in performance-driven product innovation

• A dynamic and deeply engaged consumer brand 

• A young, ambitious, Vietnamese talent team 

These pillars form Coolmate’s core competence and the reason global investors continue to stand behind the brand through multiple funding rounds. 

“Coolmate was founded with a simple belief — that Vietnam can create global-standard products, designed and produced with pride at home. This investment allows us to amplify that belief, expand to new markets, and keep building a brand that truly represents Vietnamese innovation.” 

— Pham Chi Nhu CEO & Founder of Coolmate 

“Coolmate exemplifies Vietnam’s new generation of consumer brands — digitally native, vertically integrated, and globally ambitious. The company’s disciplined execution and product innovation have set strong foundations for scale. We are proud to support its vision of becoming a leading performance lifestyle brand from Vietnam to the world,” 

- James Lee, General Partner, Vertex Growth Fund.
