Stemma
Founding story
Stemma was born from co-founders Mark Grover and Dorian Johnson’s experience with data problems in their previous jobs. At Lyft, Mark saw data users wasting 25-30% of their time understanding what data exists, what can be trusted and how to use it. With no existing solution, Mark co-created the open-source data catalog, Amundsen, to great success and wide adoption.
Stemma brings the power of Amundsen to organizations everywhere, as a fully managed data catalog.
