Our Heritage

Calculi was founded by a passionate, determined and capable group of Silicon Valley veterans who successfully drove large-scale transformations of software development, delivery and operations for several Fortune 500 companies.

Recognizing that there was no unified solution to help other companies achieve similar success, we started building Guide-Rails®, the platform for enterprise DevOps.
