# Anthesia

> Anthesia LLC is an Ohio-registered holding company that builds independent
> software and services. We operate a small portfolio of developer APIs and
> consumer apps united by a shared philosophy: quiet, considered tools that
> respect the people who use them.

Anthesia was founded in 2026. We are not a startup chasing growth at any
cost — we build products to a single standard, ship them when they meet
that standard, and operate them for the long term. We do not sell user
data, run ads, or rely on dark patterns. Contact: hello@anthesia.io.
