Theom

Theom is a San Jose-based data security company building what it calls an AI-native Data Operations Center - a platform that discovers, classifies, tracks and protects enterprise data across cloud data lakes, warehouses, SaaS and generative-AI environments. Rather than guarding infrastructure or access alone, Theom takes a data-first approach: it maps who can touch which data, scores the financial value and risk of that data, detects breach behavior mapped to MITRE ATT&CK, and enforces policy in real time. Founded in December 2020 by former Cisco/Tetration and Google engineers, it raised a $20M Series A in May 2025 led by Wing VC with strategic backers Snowflake Ventures, Databricks Ventures and SentinelOne's S Ventures, and counts Fiserv, Grammarly, Tradeweb and JetBlue among its customers.
