Who Owns Diamond Brew Coffee? The Journalist Who Quit Reporting to Disrupt Instant Coffee

Douglas Yu was not a member of the coffee industry. When discussing Diamond Brew, that particular detail is often disregarded, but it is more important than it may appear. Yu was born in China, relocated to Boston in his early twenties to attend Emerson College to study journalism, and then moved to Chicago to cover venture capital in the food and beverage industry. He learned what worked, what didn’t, and why by sitting across from founders as they pitched their products for years. The questions were posed by him. He eventually came to the conclusion that he preferred to be on the opposite side of them.

Diamond Brew is registered and operated under Diamond Brew, LLC, and Yu serves as its founder and CEO. The company launched publicly in August 2024, but Yu had been quietly building it since early 2023 — spending several months searching for the right manufacturing partner before finding a coffee roaster in China with a proprietary freeze-drying process that he felt actually solved the problem he had identified. That problem being, as he put it, that not a single instant coffee in an American grocery aisle tasted like freshly brewed coffee. It’s a simple observation. But it took someone willing to act on it.

The investor roster behind Diamond Brew is worth noting, not because it changes what’s in the cup but because it says something about how seriously people outside the coffee world are taking the concept. Michael Costello, the CEO of GNC, came on board and has publicly described the product as solving a real consumer need. Dream Ventures, Entrepreneur Ventures, Kali Mata Family Office, G/7 Venture Studio, Cambridge Companies SPG, and Beckett Industries are also among the backers. Then there are the athletes — DeAndre Hopkins and Sean Clifford among them — who have invested. Professional athletes, institutional venture capital, and executives in the health sector make up an odd combination, but it reflects the type of customer the brand is targeting: one who seeks quality, performance, and convenience without the typical compromises.

Yu worked for three years at Springdale Ventures, a Chicago-based venture capital firm that specialized in consumer brands, prior to founding Diamond Brew. After his years in journalism, that position provided him with a different kind of education than most founders receive. He has compared it to a paid MBA, speaking with CPG innovators on a daily basis to learn why some brands endure while others quietly vanish from the marketplace. When he made the decision to launch his own business, he specifically sought out a market that was high-margin, widely consumed, shelf-stable, and simple to ship. Coffee fulfilled every requirement. In particular, he believed that the perception issue with instant coffee could be resolved with the proper procedure.

This place has something worthwhile to sit with. The tale of Diamond Brew’s ownership is also a tale of a certain kind of ambition, which Yu described as a blend of idealism and pragmatism. He didn’t want to create something trendy or specialized for its own sake. In addition to the company’s initial direct-to-consumer business model, he wanted something that would endure and eventually grow into B2B channels, corporate offices, bars, restaurants, and retail. It remains to be seen if that expansion takes place within the timeframe he has in mind. However, the company has sold more than a million pods, and it has been named one of SupplySide’s top ten food and beverage game changers and acknowledged by WIRED Magazine as a top gift for coffee lovers. Such early traction is not insignificant.

It’s difficult to ignore the comparison Yu makes on the Diamond Brew website: Satori Kato, a Japanese chemist working in Chicago in 1901, invented the first successful soluble coffee in the United States, and more than a century later, another Asian entrepreneur was reviving and elevating the brewless format in the same city. It depends on your point of view whether that connection is poetic or commercial. Most likely both. However, it points to a founder who carefully considers narrative, which makes some sense considering where he began.
