Zeta Global Joins OSI To Standardize AI Data

Zeta Global announced it is joining the Open Semantic Interchange (OSI), an open-source initiative led by Snowflake Inc. (NYSE:SNOW) to standardize data definitions across enterprise systems.

The initiative aimed to build a vendor-neutral semantic model that ensured consistent metrics across dashboards, notebooks, and machine learning tools.

It also focused on creating a unified, open format for semantic metadata to improve interoperability between systems.

Zeta said the effort was expected to simplify data exchange, reduce operational complexity and support broader adoption of AI and business intelligence tools across industries.

Zeta Global CTO Says AI Needs Trusted Data

CTO and Head of Product at Zeta Global, Christian Monberg, said, "AI is only as effective as the data it can trust."

He added that fragmented data definitions reduce confidence in analytics and AI systems, especially at scale.

Zeta said that as part of the Open Semantic Interchange, it would help develop a shared standard for semantic models to improve data interoperability and reduce integration friction for enterprise customers.

Josh Klahr, Director of Analytics Product Management at Snowflake, said the collaboration aimed to establish a unified semantic data standard to ensure consistency and clarity across the broader ecosystem.

Zeta Global Seen As Undervalued AI Play

Shay Boloor said the company is becoming more important as AI marketing still relies on accurate customer identity data, especially as third-party cookies disappear.

He added that Zeta's SuperGraph and Athena tools could become more valuable for large-scale targeting and personalization.

$ZETA matters in the AI era because AI can generate campaigns but it still needs to know who the customer is.

Lupton Capital CEO Jonah Lupton said Zeta could be 60%–80% undervalued, noting it trades at about 10x EBITDA but could justify a higher valuation if it maintains strong profit growth.

$APP is much bigger, better company but doesn't mean it's not worth owning $ZETA at 10x NTM ebitda… $ZETA is probably 60-80% undervalued… should be trading at 16-18x NTM ebitda if they're going to grow ebitda at 28-30% CAGR for the next few years.
