Altair has acquired Cambridge Semantics, a modern data fabric provider and creator of one of the industry’s analytical graph databases. Cambridge Semantics’ graph-powered data fabric technology accelerates the creation of comprehensive enterprise knowledge graphs, integrating the web of structured and unstructured enterprise data together into a single, simplified view, Altair explains.

Bringing together Cambridge Semantics’ graph technology with Altair’s tools for data analytics and data science offers companies the capability to work with advanced analytics ecosystems that inject artificial intelligence (AI) into day-to-day business operations, according to Altair.

“Knowledge graphs are key pieces of data fabrics. They put the right data in the right hands at the right time. We believe Cambridge Semantics brings the fastest and most scalable knowledge graphs to organizations who have significant data volumes and deep questions,” says James R. Scapa, founder and chief executive officer, Altair. “Additionally, knowledge graphs are critical for successful generative AI applications as they provide the business context necessary to ground generative AI models, eliminate hallucinations, and dramatically improve response quality.”

Cambridge Semantics’ technologies will be integrated into the Altair RapidMiner platform, adding knowledge graph, data governance, data virtualization, and data discovery technology to the platform’s existing data preparation, ETL, data science, business intelligence, MLOps, workload management, and orchestration tools.

“Joining Altair is a natural transition for Cambridge Semantics as we seek to accelerate the pace of our technology adoption,” says Charles Pieper, chairman and chief executive officer, Cambridge Semantics. “Cambridge Semantics has historically been successful with Fortune 500 government, defense, life science and manufacturing organizations. Bringing Cambridge Semantics to Altair’s broad customer base through the Altair Units business model—and integrating it into Altair RapidMiner—is an exciting prospect for us and for our customers.”

Cambridge Semantics was founded in 2007 by an innovation and engineering team from IBM’s Advanced Technology Group with a shared belief that semantic graph data models were a technology made to help organizations exploit their data: fueling analytics, revealing new insights, and enabling competitive differentiation. 

“This acquisition adds deep data warehousing expertise to our already strong analytics and data science team, creating an enhanced core group of engineers that understand the entire data lifecycle—from data creation to real impact,” says Srikanth Mahalingam, chief technology officer, Altair.
