Tomoni is a closed-type empathy-community SNS where people who share the same circumstances and interests can meet with peace of mind. It is a mobile-first platform where you record your feelings through timeline posts and diaries, and connect via approval-based friends and one-on-one messaging.
A new-platform launch story: solving "no safe place to meet, no lasting record, no means to operate" by building in-house from scratch in 12 months.
The community app operator aims to build a closed community where people who share the same circumstances and interests can meet safely and support one another. Peace of mind, safety, and ease of continued use are at the core of its value.
On mainstream SNS, information spreads widely, making it hard to protect privacy and psychological safety. So we set out to build a dedicated, mobile-first community platform from scratch.

Mainstream SNS spread information widely,Psychological safety is hard to maintain.
Feelings and daily changesA means to keep and revisit did not exist.
Inappropriate posts and harassmentAn operational system to prevent it did not exist.
We built the mobile app, community platform API, diary/connections, and operator CMS in-house from scratch — designing a reassuring user experience and easy-to-sustain operations end to end.
