Stemma’s Story

Stemma was born from our co-founders’ shared experience of data problems relating to discovery, understanding and trust.

In his former role at Lyft, Mark witnessed and sought to rectify issues that caused data users to spend 25-30% of their time ascertaining what data exists, what data is trustworthy and how to apply it. With no existing solution in sight, Mark began a mission to make discovering and understanding trustworthy data easier.

Amundsen was a resounding success at Lyft, enjoying a rapid adoption rate with 80% of data analysts, data scientists and data engineers using it every week. When Amundsen became open-source, Dorian joined as a dedicated committer, having seen its promise at Heap and at other data-driven companies.

Following their achievements with Amundsen, Mark and Dorian looked to build on its success by bridging the gap between data producers and consumers. The pair founded Stemma in 2020 to provide a fully managed enterprise solution offering powerful data discovery tools and richer metadata. Today, Stemma is enabling a diverse range of clients to gain total trust in their data, from modern logistics companies to leading financial institutions.

Dedicated to Open Source

Stemma is rooted in open-source. Mark, Stemma’s co-founder and CEO, is the co-creator of Amundsen: the leading open-source data catalog, with the largest community and the most integrations.

Stemma's engineers are committers and contributors to Amundsen.
