ALTR

ALTR sells automated data access governance for cloud data warehouses, with Snowflake as its primary and most developed integration. The core problem it targets is a real operational one: as organizations centralize sensitive data into platforms like Snowflake, the number of people and service accounts with query access grows faster than security teams can manually review, and native warehouse permissions are usually too coarse to enforce need-to-know access at the row or column level. ALTR sits alongside the warehouse to continuously discover and classify sensitive data, then apply and monitor fine-grained access policies without requiring the warehouse’s own admins to hand-build every rule.

The company markets itself as a Snowflake Premier Partner and has built specific integrations recognized within the Snowflake Horizon governance ecosystem, positioning ALTR as a governance layer that plugs into a specific cloud data platform rather than a generic, protocol-agnostic DLP tool. That focus is a real trade-off: it gives ALTR deeper, more automatable controls inside its supported platforms, but a narrower addressable footprint than data-security vendors that aim for cross-platform coverage from day one.

Founded in 2017 by James Beecham and Chris Struttmann and based in Austin, ALTR has raised roughly $55 million across three rounds, including a $25 million Series C in November 2023. The company reports data on its Snowflake Partner Connect activations growing sharply since 2021, though that figure is self-reported. ALTR’s early positioning leaned on blockchain-based data protection concepts; the current product and marketing have shifted to a more conventional data governance and access-control framing aligned with how enterprise data security teams actually buy.
