Behind the Scenes of Slack Rail: Insights and Innovations from Giliita Co.

The Origins and Development of Slack Rail



Giliita Co., based in Kita-ku, Tokyo, known for its innovative "Core Awakening®" products, recently hosted its inaugural online meeting at the members-only community 'Isawo-chan Secret Laboratory', marking a significant milestone in engaging with its user base.

Sharing The Development Journey


During this meeting, Giliita's CEO, Yuuki Takashima, detailed the story behind the creation of Slack Rail, touching on various aspects of the development process, including:
  • - The inspiration and vision that led to Slack Rail's conception.
  • - Background stories of the prototypes developed during the innovation phase.
  • - The daily challenges and learnings encountered during product development.
  • - The philosophy infused into each product.

Participants found the sharing enlightening, with comments like, "It was fascinating to learn about the development process," "My perspective on the product has shifted," and "I felt like a part of the development journey."
This meeting proved to be more than a simple information-sharing session; it reaffirmed the community as a valuable space to collectively embrace Giliita's philosophy.

The Community's Focus: Sharing the Process


The 'Isawo-chan Secret Laboratory' is designed not only to showcase completed products but also to highlight the process and thinking that leads to their creation. Giliita's products often emerge from real-world feedback and experiences, involving numerous trials and unpublished ideas. This community offers an opportunity to experience the essence of manufacturing by sharing these insights.

The Meaning Behind 'Secret'


The term "secret" in the community's name does not imply exclusivity for the sake of withholding information, but rather serves as a means to cultivate a deeper dialogue in manufacturing. Members are encouraged to engage actively and understand the value of the creations shared.

Future Directions


Giliita plans to continue these online meetings, focusing on sharing in-development products, fostering discussions among members, and collecting feedback on prototypes. The aim is to bridge the gap between creators and users, enhancing collaborative growth in the community.
