Epsilon3

Epsilon3 is the OS for spacecraft and complex operations. Put simply, it is about running projects, docs and workflows in one shared workspace.

Who is it for? Mostly teams that want fewer tools. Alongside the main category they mention Productivity Tools and Space Travel. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Epsilon3 is based in Los Angeles, California. You can read more at epsilon3.io.

Before you commit, look at automation limits, permissions, and per-seat cost at scale. Ask for a trial on your own data, not a canned demo.

If you have worked with Epsilon3, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
