Stemma enables a diverse range of clients to serve data-informed insights to all business users.
Data teams these days increasingly need to make data available to users throughout the organization. This new mission makes it all the more important that the data is trustworthy. Without a modern catalog to ensure this, new sources of data go undocumented, engineers cannot see the impact changes have on users, and platform adoption ultimately suffers.
Stemma gives our customers the tools to make sure their data can be trusted in a self-serve culture. We provide automated data stewardship, deep insight into data use, and seamless integration into existing user workflows.
The data catalog for the modern data stack
Data Discovery
Stemma integrates with best-of-breed tools and workflows to bring tribal knowledge into your data catalog. Users will find the data they need in Stemma while keeping the workflows they’ve built into habits.
Change Management
Data Analysts can now see the source of data and easily connect with data owners and get advanced warning from data engineers about impending changes. The people who draw insights from data no longer need to feel like they are the last to find out when data gets shut off or delayed.

Our Philosophy
Our team has watched data practices evolve at companies making some of the biggest bets on data. In our experience there are common approaches that have led to success for modern teams.



It is our mission to make your data program successful, not just sell you a data catalog. From scoping your effort to decentralize data all the way through onboarding your users, Stemma has experience to help.

Seamless Integration with Your Favorite Data Sources
Decentralize data with security in mind
We offer two ways of deploying Stemma, both of which are secure.
Our hybrid deployment model is ideal for customers who want the benefits of data residency without the cost of self-hosting. In this model, Stemma hosts the Control Plane while the Data Plane is hosted in your cloud environment.
In our standard deployment model, Stemma hosts both the Control Plane and the Data Plane.
