Cyberhaven
Cyberhaven is a data security company that protects enterprises from data exfiltration and insider risk by tracing how information moves rather than just where it sits. Founded in 2016 by five PhD researchers with roots in the DARPA Cyber Grand Challenge, the company built a proprietary 'data lineage' engine and an AI layer, Linea AI, that combines Data Loss Prevention (DLP), Data Security Posture Management (DSPM), Insider Risk Management, and AI security into one platform. Reaching a $1 billion valuation in April 2025 after a $100M Series D, Cyberhaven serves customers such as Snowflake, Motorola, Reddit, and major law firms.
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.
