Creating platforms to
eliminate widespread toil from
society and inspire innovations

Message

Keep creating

A few years have passed since our company was established
and we have directly felt the drastic social and technological transformation in those years.

We, 3-shake, are on a mission to continuously create innovative products that support the foundation of society.
To this end, we need to build flexible and tenacious teams.
That's why we have established the following team policy.

“All members shall play a leading role, respect and value one another, and enjoy developing a new future through friendly rivalry.”

3-shake prides itself on its optimal corporate culture, where employees take pride and pleasure in their daily initiatives as professionals.
Needless to say, these teams do not create conventional products.
I am certain that they will create products that will surprise the world.

Stay tuned for our future initiatives!

CEO

Takuma Yoshida

After joining DeNA in 2011, Yoshida engaged in infrastructure projects for the payment service provider Paygent as an infrastructure engineer. He has been using AWS since it was launched in the Tokyo area, so he is keenly aware of the impact that cloud platforms have on society. He joined Poppin Games Japan Co., Ltd. during its startup phase in 2013. There, he oversaw the infrastructure layer and led all aspects of technology, business, and management during the venture company's startup phase as a game producer, the head of the business strategy office, etc. In January 2015, he founded 3-shake Inc. to create an infrastructure platform originating in Japan.
Born in 1987 in Tokyo, he graduated with a Master's in Quantum Engineering from the Graduate School of Engineering, the University of Tokyo.

Origin

Origin of 3-shake

3-shake was named after the three-way handshake, a network technology term.
Our mission is to continue to provide services that serve as the foundation of society and accelerate innovations,
just as this technological method serves as the foundation of the Internet.

Philosophy

3-shake's core values

  • 01

    Provide products and
    services that change society

    We will focus on whether the value we provide can fundamentally change social activities (engineering and life activities).
    It is not necessarily about becoming the first in the world.
    Sometimes, existing products or services are not transforming society for some reason (legacy technologies, UIUX, price, etc.).
    We will solve the problem to make sure the potential of these products and services is not wasted, thus leaving an impact on the world.

  • 02

    Turn technologies into value

    We will continue to be a group of tech professionals that turn technologies into profit and contribute to society.
    At the same time, we aim to make technologies (value) available to users at reasonable prices.

  • 03

    Our excitement is the key

    You cannot provide products and services that change society overnight.
    You need to analyze users for a long period of time and continue to tackle issues head on.
    To this end, it is important that we ourselves feel excited and enjoy working on the products and services.
    We will deliver our excitement to users as a sign of our passion.
