The world needs more daring

The existing social system has many problems. It is thought that in order to solve these problems and create true impact to the society, many disruptive innovations will be necessary. However, the world has a deficiency of the mechanisms that would sustain the startups that provide that disruptive innovation and social impact.

We need mechanisms oriented toward supporting disruptive innovation and impact, ones that are not held back by existing frameworks.

Conditions necessary for mechanisms that support disruptive innovation and social impact

  • Efficient fundraising mechanisms that eliminate excess costs
  • Mechanisms for determining which ventures are truly innovative and have potentials to create great impact
  • Exit mechanisms that maximize benefit for investors and supporters, which has been difficult to achieve when investing in disruptive or impact ventures

What we do?

Hotaru is a venture studio that discovers talented teams with great ideas, nurtures their ideas, and connects them with those who want to participate in the innovation and social impact. Our vision is the decentralized world where the true impact innovations are supported by the power of the public.

Who we are?
