# 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.
