YUKA KISO AND CUCULI: SERENDIPITY AS A DESIGN PROBLEM, NOT AN ACCIDENT

Yuka Kiso is building Cuculi to engineer serendipity at scale — using technology to make real-life connection easier, not to replace it.

Social products often optimize for engagement metrics that correlate with addiction: infinite feeds, passive consumption, and parasocial relationships. Cuculi's philosophy cuts against that grain. Kiso believes technology should not replace human connection; it should reduce the friction of experiencing life together — the coordination tax that makes spontaneity feel impossible for busy adults.

Cuculi helps people discover and experience shared moments, turning spontaneous social connection into something you can plan for without draining it of joy. The paradox is intentional: serendipity sounds opposed to engineering, but in practice, people miss each other because scheduling is hard, not because they lack desire.

The company is Seed-stage with early revenue, suggesting users will pay when a product genuinely increases the frequency of meaningful in-person connection rather than merely simulating community online.

Cuculi is a bet that the next generation of social technology will win by respecting physical reality — helping people show up for each other, rather than optimizing them to stay inside a screen.
