Gain Total Trust in Your Data

Everyone has access to data, but few know what exists, what’s trustworthy and how to use it. Stemma makes finding trustworthy data easy and offers an always up-to-date view of your data’s usage at any time.
Stemma for Data Scientists & Analysts
Rather than being the last to find out when data gets shut off or delayed, Stemma users are always in the loop and have oversight on what’s changing with their data.

We keep users up-to-date through automated documentation based on common usage patterns.
Stemma for Data Engineers
Not knowing who or what a data change will affect means that data engineers simply have to spray and pray.

The volume of data that companies need to collect and process is growing exponentially. Stemma removes the complexity and stress of tracking and navigating the flow of new and ever-evolving data, through automated lineage tracking.
Stemma for Data Governance
Organizations often rely on Slack conversations and continuous shoulder-tapping to gain trust in data. This is error-prone and time-consuming.

Stemma uniquely augments your data with automated documentation, so you don’t have to document and curate every single data set.

Lower your Time
 to Value with Stemma

Stemma is a fully managed data catalog built on Amundsen
Stemma makes deployment and management a breeze. With a one-time implementation cost, getting up and running is simple.
Automated metadata powered by intelligence
Easily see common join and filter conditions on your data, derived from existing usage patterns. Slack integration makes tracking and following all related conversations simple. Stemma removes the need to curate every single data set. Curate only the most impactful data. Let automation take care of the rest.

Stemma prevents the wrong decisions from being made, while continuously reducing the total cost of ownership.

How it Works

01

Ingest metadata via push, pull & API methods

Ingest from:

  • Data warehouse
  • BI tools
  • Orchestration systems
  • Slack
  • Github, and more...

02

Automated metadata through intelligence

We use existing usage patterns, user’s role & recent activity to power:

  • Related conversations in Slack
  • Common join and filter conditions
  • Personalized experience

03

Accessible through Stemma User Interface & API
  • Access all the ingested and derived metadata through an intuitive data discovery experience in a UI
  • Power programmatic use-cases through the Stemma API

Catalog Use Cases

Discover Trustworthy Data

Enable your analysts and data scientists to discover trusted data on a topic, understand its nuances and the best practices on how to use it.

Faster Onboarding

Bring analysts and data scientists up to speed by sharing rich context about the most commonly used data within your team, populated through curation and usage patterns.

Understand the Impact of Changes

Help your data engineers to understand the full impact of changes through data lineage that is always up-to-date.

Debug Data Issues

Make it easy for your data engineers to understand where data is coming from and see recent changes that have happened on a table.

Data Governance

Define business terms and marry them with technical data.
Further remove the burden of managing your data by simply certifying your most impactful data sets. Receive automatically, augmented documentation for the rest.

Enable Data Mesh

Federate communication ownership across data producers and consumers. Enable consumers to report issues and request metadata directly from the producers, without being the bottleneck.
