Over the years, Open Network Lab has helped hundreds of companies build their businesses and avoid common stumbling blocks, to fast-track their success.

All participating teams can receive around 10 million yen to fund their activities. It depends on the company’s situation and performance. The entire process leading to the investment, including interviews can be completed online. In addition, we provide ample support for subsequent financing.

Global Incubation Stream

We will make the best use of the global network that Digital Garage has built so far
to discover and incubate startups that can compete on the global stage.


Build value that will become the nucleus of your business

You can focus all your efforts on growing superficial metrics related to sales and marketing, but is this really “true growth?”

We have seen countless examples of companies that have failed because they were focused on the wrong things at the wrong time. Startups certainly have different engines for success, but what they all have in common is the need to be able to clearly articulate, “what problem are you solving for who”.

At Onlab, we help startups crystalize the value that is core to their businesses so that they can achieve sustainable growth in their operations, even after the program.

Idea verification

Systemically test your hypotheses to navigate questions such as, “do customers really need what we offer?,” and, “is this the correct solution?”, to build a strong foundation for your business.

Accountability and peer pressure

The three-month program consists of regular check-in meetings with mentors and a demo day at the end of the program, among other events. This set schedule motivates startups to grow faster than if they were on their own, due to higher accountability and peer pressure from other startups in the same cohort.

Community of entrepreneurs

This community includes startups in the same stage inspring each other to work hard, alumni who have already exited, and dedicated mentors who can provide ongoing advice. We also provide an environment where founders can easily interact with each other.

Continuous learning environment

Onlab Campus holds webinars and seminars based on startup needs and market conditions, which are open to our startups at any time. Startups also have access to templates that can be used in various situations.

Partners to bounce ideas off

It’s common for startups to slow down after graduating from the accelerator program. But at Onlab, startups can set up regular, one-on-one meetings with our team to discuss ideas and receive feedback— helping to maintain momentum after finishing the program.

Support from experts in various fields

The alumni incubation team is dedicated to supporting program alumni—providing professional services in areas ranging from finance, business development, traction, and product development.

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.
