We’re building the calmer way to meet
Semiora started because a Monday kept double-booking itself. Today we build scheduling software that treats attention as the scarcest resource it has.
Four ideas we build by
They are written on the wall, but more importantly they decide what gets merged.
Time is the product
Every feature is judged by the hours it hands back to the people using it.
Chat beats email
Context should live where the work happens, not in a thread nobody can find.
Default to open
Our scheduling core is public, hackable and documented — read it, fork it, ship it.
Craft over churn
We ship less, polish more, and keep the promises already on the page.
From a bad Monday to thousands of calmer weeks
Short version. The long version is best told over coffee, booked through a Semiora page, obviously.
2021
The double-booked Monday
Two cofounders, one client call, zero shared calendars. The idea showed up before the coffee did.
2022
Booking pages ship
The first release: one link, real availability, and a confirmation email that actually arrives.
2023
Team chat goes built-in
Channels landed next to the calendar, and the great tab-juggling finally stopped.
Today
High-concurrency infrastructure
From individuals to growing teams — zero race condition scheduling at global edge scale.
Engineered on modern standards
The architecture powering Semiora's booking pages, PostgreSQL advisory locks, and round-robin distribution is built on open standards, typed APIs, and strict data protocols.
- PostgreSQL advisory locks
- WorkOS SAML/SCIM
- Native WebRTC (Roadmap)
- Transactional advisory locking eliminates double-booking race conditions
- Native WebRTC browser video rooms in active development for zero-token conferencing
- Zero vendor lock-in with open webhook and REST API standards
