Building Cultural Food Brands.
We seriously enjoy every second of life. We just wanna be happy.
From concept, product and visual identity to retail, operations and growth. We don't just advise brands. We build them.
We collaborate with people who shape culture.
"Not simply as ambassadors. As partners. Co-Founder and Equity Partner."
We selectively invest in companies and venture studios around the world that share our belief in the power of culture and creativity.
At the end of the day, we just want to be happy — and have fun creating with people who inspire us. Culture makes people want something. Business turns that desire into value.
RUMBLE VENTURE STUDIO is a Food Venture Studio that brings together food, culture, creativity, and business to build brands, grow them, and carry them into the future.
At 21, Yumi founded a music label. At 24, she sold it. That was her first company — and her first exit. Since then, she has continued to build brands from the ground up, grow them, and, when the time is right, hand them over to companies with greater resources and capital to take them to the next stage.
As a serial entrepreneur, I have repeated this cycle of building, growing, and exiting brands. Throughout that journey, one principle has always been important to me: building brands together with the people who shape culture.
In the United States in particular, I had the opportunity to start brands with people who would later become powerful forces in global culture and soft power.
Culture has the power to attract people. Business has the power to turn that attraction into sustainable growth. When the two come together, a brand can become far more than a product — it can become something with meaningful enterprise value.
Every brand has its own timing. There is a time to create something from zero. A time when people begin to love it and the brand grows rapidly. And a time when greater capital, resources, and infrastructure are needed to take it to the next level. At the same time, no brand grows forever.
That is why understanding where a brand's true value lies, when to accelerate its growth, and when to entrust it to the right next owner is just as important as creating the brand itself.
As I gained more experience through my own exits, I naturally began angel investing in entrepreneurs and brands, while also advising founders on brand strategy, growth, and exits.
We build brands ourselves. We create value alongside the people who shape culture. We grow those brands. We take them to their next stage. And we invest in entrepreneurs and companies that, like us, are creating new value.
What were once separate activities have now become one integrated platform: RUMBLE VENTURE STUDIO.
We create food brands from the ground up — from product development, visual identity, and physical spaces to operations, strategy, and growth. We don't simply advise from the sidelines. We build hands-on.
We partner with people who shape culture — individuals with talent, creativity, influence, and the ability to move people. Together, we turn ideas and cultural relevance into brands with real business value.
We invest in entrepreneurs, companies, and venture studios around the world that combine the power of culture, creativity, and brand building.

We believe we are here to be happy. That's why, for us, who we work with and what we create together truly matter.
We want to build brands with people who inspire us — people who make us feel excited about what's possible. Together, we create something we genuinely believe in, grow it into a brand people love, and ultimately build lasting enterprise value.
I have founded and successfully exited three companies. Through those experiences, I've gained knowledge, opportunities, and relationships that I don't want to keep to myself. I want to share them with people I value, and create something meaningful together. That idea became RUMBLE VENTURE STUDIO.
With a particular focus on food, we partner with talented and influential people to create brands that don't yet exist — building them from the ground up and growing them into businesses with real value.
We build exciting brands with people who excite us. And we turn that excitement into lasting value.
Founders, partners and investors who share the same appetite for culture and craft — we'd love to hear from you.
