Moving entertainment and education
forward with software.

Miyayu Lab is a software studio building products for entertainment and education, founded in January 2025. Drawing on the founder's experience since 2018 — from viewer experiences reaching hundreds of thousands of people to programming materials for kids — we ship products that keep getting used, quickly, with a small team.

How we build

What we care about

  1. 01

    Start from the people who use it

    Creators and viewers, teachers and kids. We design around the experience of the people on the other side of the product.

  2. 02

    Ship small, learn fast

    We deliver the smallest useful version and improve quickly based on real feedback, actively adopting new tools including AI.

  3. 03

    Own it until it keeps being used

    Shipping isn't the finish line. We take care of maintenance and operations so products stay in use for the long run.
