Nvidia has confirmed it is acquiring Illumex, a Tel Aviv data-management startup that auto-builds semantic ontologies across enterprise databases for AI agents and analytics. Israeli reports peg the deal at $60 million, with some sources citing a higher $75 million figure.
The semantic layer Nvidia was missing
Illumex's software unifies the vocabularies, joins and governance metadata scattered across an organisation's warehouses and lakehouses, then exposes that as a single semantic graph an AI agent can query. Nvidia plans to bundle that layer into its enterprise-AI software stack and pitch it to large customers and cloud partners that already buy GPUs but struggle to operationalize agents against messy internal data.
$13M in, $60M out — and an Israeli AI run for Nvidia
Founded in 2021 by Inna Tokarev Sela, the former AVP and head of AI at Sisense, Illumex had raised about $13 million from investors including Cardumen Capital, JIBE and ICON. The exit deepens Nvidia's acquisition run in Israeli AI tooling: it follows the 2024 purchase of model-compression startup Deci, and lands as hyperscalers commit unprecedented capex to AI infrastructure.
Why the data layer matters for agents
The biggest blocker to enterprise AI agents isn't model intelligence — it's the ability to ground actions in trustworthy data. Adding Illumex to the Nvidia AI Enterprise stack mirrors the playbook used by hyperscalers and integrators racing to ship agent platforms, and complements Nvidia's recent fab-floor partnership with TSMC on physical AI.
Closing details
Terms have not been formally filed, and Nvidia did not state a closing date. Illumex employees are expected to roll into Nvidia's Israel operations, which the chipmaker has steadily expanded since its $7 billion acquisition of Mellanox in 2020.
