Alumni’s Voice

Batch 14

Gary Lo

Onlab mentors helped us improve our pitch and make a detailed business plan. What impressed us the most was that the mentors saw our business from different angles and they had highly specialized perspectives as entrepreneurs with track records of success.

Batch 17
Giftpack Co-founder

Archer Chiang

We learned how to advance business in Japan and the importance of connecting with many talented people and big corporations who can continuously help us even now.I can’t put everything into words because I’ve learned so much. I would definitely love to retake the program whenever I have the opportunity.

Batch 12 Co-founder

Our mentor treated us very well and was very patient. For example, in the beginning I thought 5 minute pitches were ridiculous, but he was able to help me understand from an investors’ point of view, why it made sense to do a 5 minute pitch, and what investors expect to see.
