Who We Are

Caelo Software BV develops solutions for people who spend too much time managing their email. Caelo started one day several years ago when one of our founders got frustrated looking for an email message. Since that day we have worked hard at creating email technologies that really help people manage their email.

Caelo has developed patented technologies to automatically organize email - technologies that offer a fundamental improvement in how people use email. These technologies are showcased in our award-winning product, NEO Pro.

Caelo is pronounced "kay-lo" (rhymes with halo). Loosely translated, it means "the heavens" in Latin.
