## Summary

A small brunch gathering for people who enjoy the overlap between pure mathematics and computer science. The session is themed around a Mathematics Edition: attendees bring favorite theorems, proofs, or concepts to share and discuss, with conversation focused on the structures that underpin programming.

The format is intentionally low-key, a relaxed meal at the Beltempo restaurant inside Hotel Metropolitan Edmont Tokyo near Iidabashi. First-time attendees who RSVP and are confirmed on the attendee list have their meal covered. The group is small by design, so RSVPing is required to find them on the day.

## About the community

TechBrunch is a recurring small-group meetup that pairs casual brunches with technical conversation. Each edition picks a theme (this one is pure mathematics) and invites mathematicians, computer scientists, and curious developers to dig into it over a meal. The vibe is intentionally intimate rather than networking-heavy, and first-time attendees who RSVP get their meal covered as a welcome.
