What Others Say

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.


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.


When it comes to investors, QuestVC has to be on the top of any entrepreneur’s wish list. They are battle-hardened entrepreneurs who have achieved massive success in building a company, and their backing has given us great confidence. QuestVC has done an admirable job supporting and building a community of startups. Ubersnap has certainly benefited from being a part of this ecosystem.


We first met James in a pizza bar in Silicon Valley a few years ago and reconnected while working out of Plugin@Blk71. QuestVC was one of Burpple’s first angel investors and believed in the team right from the start. He constantly challenges us to think and swim bigger, and is always inviting to hear us out whenever we face problems. Helpful, friendly and down to earth.

yet high and low I’ll search with my will unbending.

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.
