Tamr Secures $21 Million in Growth Equity Investment Led by Volition Capital to Accelerate AI-Native Master Data Management

Investment will fuel continued innovation in agentic data management as enterprises move AI initiatives from pilot to production

BOSTON, Oct. 14, 2026 /PRNewswire/ -- Tamr, the leading AI-native master data management (MDM) platform, today announced $21 million in growth equity financing led by Volition Capital, a Boston-based growth equity firm, with participation from existing investors. The new capital will help Tamr fuel product innovation and expand the platform's agentic data mastering capabilities.

AI agents today depend on clean, accurate data to operate effectively—yet many organizations still struggle with overlapping, incomplete, and inaccurate records across CRM, ERP, procurement, and other operational systems, as well as within their data warehouses and data lakes. As companies move from AI experiments to AI in production, the importance of a trusted data foundation increases dramatically. Tamr addresses this by unifying, cleaning, and enriching fragmented enterprise data—enabling organizations to work from a single source of truth and providing the context needed to power enterprise AI initiatives, improve decision-making, and drive revenue growth.

Dhesen Ramsamy, Group Chief Technology and Data Officer at Old Mutual, stated, "We are on the accelerated path to becoming an AI-led financial services organization, and that starts with having data that AI can trust. At our scale, mastering millions of records from multiple product systems, we chose Tamr with its AI-native approach as our group's real-time MDM platform. Tamr has partnered closely with Old Mutual Group over the years, delivering solutions to problems that the legacy systems could not facilitate, and we view Tamr capabilities as foundational to our group growth ambitions."

Originating from research at MIT's Computer Science and Artificial Intelligence Laboratory, Tamr was co-founded in 2013 by a team of academic innovators including Dr. Michael Stonebraker, winner of the 2014 ACM A.M. Turing Award; Andy Palmer, who now serves as chairman; Alex Pagan, Tamr CTO; Ihab Ilyas of the University of Waterloo; Daniel Bruckner; and George Beskales. The company holds 19 patents in AI/ML mastering, clustering, and data curation, and its platform is used by global enterprises across insurance, financial services, healthcare, life sciences, manufacturing, technology, retail, and higher education.

Led by CEO Anthony Deighton, Tamr enters this next phase of growth with strong momentum, having more than doubled its SaaS revenue in its prior fiscal year. This progress has been accompanied by continuous product innovation, with the company adding new, powerful AI agents to the platform and enhancing its unique Curator Hub, an agentic data curation capability that pairs AI agents with human expertise. Additional recent product developments include a "Bring Your Own Agent" architecture for low-code integration of custom AI agents; multi-domain mastering across products, locations, and custom entities; and enterprise knowledge graph functionality for identifying and leveraging cross-entity relationships.

With the new capital, Tamr plans to further advance its agentic capabilities, particularly around data curation and context delivery, while continuing to scale the platform's underlying AI and operational infrastructure.

"As enterprises put AI to work across more of their operations, data quality and reliability become non-negotiable," said Anthony Deighton, CEO of Tamr. "I believe the only way to solve the messy, siloed data problem in the enterprise is by using AI to prepare data for AI applications. This new investment and partnership with Volition enable us to accelerate development of the agentic capabilities our customers need to solve this problem at scale."

Tomy Han, Partner at Volition Capital, said: "Enterprise AI programs stall most often at the data layer, and budgets are increasingly shifting toward the data foundation as a result. But legacy rules-based engines won't solve the problem, and neither will AI bolted on to the side. Tamr is one of the very few data platforms that was AI-native before the term existed, where machine learning is the architecture and not a feature. That's what drew us in, and it's why blue-chip enterprises across industries have built their data foundations on Tamr."
