Tamr, Inc.

Tamr, Inc. develops master data management software that uses machine learning to clean, unify, and enrich fragmented enterprise data. The company was founded in 2013 in Cambridge, Massachusetts, by Andy Palmer and Michael Stonebraker, a Turing Award-winning database researcher, growing out of earlier data-integration research at MIT.

The company's platform applies machine learning models and AI agents, combined with human review workflows, to match, merge, and standardize records across disparate enterprise systems, producing what it calls golden records for use cases such as customer data, supplier data, and product information management. Tamr has marketed its software to industries including financial services, life sciences, manufacturing, and the public sector, positioning its approach against traditional rules-based master data management tools from vendors such as Informatica and Reltio.

Tamr has raised more than $200 million in venture funding from investors including Google Ventures, New Enterprise Associates, ICONIQ Capital, MassMutual Ventures, and Hewlett Packard Enterprise, among others. The company has gone through several leadership transitions since its founding, with Nidhi Aggarwal named CEO in recent years after earlier stints by co-founder Andy Palmer and other executives.
