What Others Say

We met James Tan when he was one of the judges during our first public pitch at Startup Asia. He could see the potential in Vibease when most people thought it was just a toy. Since then, he has been very supportive and provided us with real feedback. His insights and connections in the China and Singapore startup ecosystems definitely help us a lot. We are really glad to have him as our investor and mentor.


QuestVC was very helpful in the setting up of our overseas office – hiring, fund-raising and connecting with the other portfolio companies, all of which have been critical to speed of execution in our overseas expansion.


The best kind of investors are those who are entrepreneurs themselves, and James is one of the best in that category – he is authentic, supportive and knowledgeable. He is both a great coach for founders, as well as a master tactician in execution, a combination that is rare and incredibly valuable to find in an investor.


Incredibly helpful, adds real value. Appreciates the drive.

QuestVC is China’s leading venture fund for technology companies that have scalability and replicability in large internet communities.



Our portfolio companies span the globe and are in different stages of development. Our investment thesis focuses on scalability and replicability in large internet communities.

What does that mean?  A thought on seamlessness:

The pace and breadth of change today is redefining market adaptation and adoption. In a world saturated with digital connectivity, anyone can be connected to anyone else, at any time, from anywhere. Map this to the multitude of market opportunities, from how a company buys or sells its products and services, to how it registers, queries or authorizes purchases. And take it even further, to how customers’ purchases and experiences could be shared with an audience of millions, at virtually no incremental cost. That’s seamlessness in transaction, administration and marketing.


Our Team

The QuestVC team comprises highly experienced individuals with deep first-hand industry expertise.  Leveraging our strong networks in China, Southeast Asia and the region, and our personal experience with start-ups, we deliver extremely valuable, reliable and innovative services to entrepreneurs.

We believe it takes an entrepreneur to understand another, and thus we have many successful entrepreneurs in our network who are always ready to lend a hand.  In addition, our affiliations with global partners provide inspiration and assistance in funding, mentoring and growing our portfolio companies.
