Business Overview: Zeta Global Holdings Corp. (NYSE: ZETA)

---

Executive Summary

Zeta Global Holdings Corp. is an AI-powered, omnichannel marketing technology company headquartered at 3 Park Avenue in New York City. Founded in 2007 by David A. Steinberg and John Sculley (former Apple CEO), Zeta built its business around identity-resolved consumer data at scale and went public via a traditional IPO on the NYSE in June 2021. The company's core offering, the Zeta Marketing Platform (ZMP), combines a proprietary identity and data layer with AI-native infrastructure and omnichannel activation tools, letting large enterprises run data-driven marketing campaigns across email, display, and other channels from a single platform.

Zeta's model centers on migrating customers up an engagement curve: it signs enterprises to quarterly or annual subscription agreements, often layered with usage-based pricing, and then expands usage until a customer becomes "scaled" or, at the top tier, "super-scaled" (trailing-twelve-month revenue of at least $1 million). By FY2025, the company had 2,651 total customers, 602 scaled customers, and 184 super-scaled customers — and those super-scaled customers alone generated 87% of total 2025 revenue, the clearest evidence of how the business actually monetizes.

Why it matters: Zeta is one of the few scaled, profitable-at-the-EBITDA-level independent marketing-technology platforms competing directly against much larger incumbents (Salesforce, Adobe, Oracle) and against a long tail of point-solution vendors. FY2025 revenue grew 30% to $1.30 billion with Adjusted EBITDA of $278.7 million (21.4% margin), and management guided FY2026 revenue to $1.75-$1.76 billion (34-35% growth) with full-year GAAP net income turning positive — a rare combination of scale, growth, and improving profitability in the marketing-cloud category.

1. Core Business Model & How They Work

Zeta sells access to its Zeta Marketing Platform under subscription contracts, then grows revenue per customer as that customer adopts more of the platform's modules and increases usage-based activity (sending more messages, running more campaigns, activating more data).

                                                                                       |
                                                                                       v

                                                                                       v

This "land and expand" dynamic is the single most important driver of Zeta's economics: the company's growth strategy is explicitly built around moving customers up this ladder rather than primarily adding new logos, which is why management discloses customer-tier counts as a core operating metric (though it has signaled it will stop reporting scaled-customer counts in quarterly filings going forward, continuing to disclose only super-scaled figures).

2. Business Segments

Zeta does not report formal, discrete operating segments; it runs and discloses its business as a single integrated platform, broken out by product (ESP/Zeta Messaging, CDP+, DSP) and by customer industry vertical rather than by segment. 2025 revenue by vertical: consumer & retail (24%), travel & hospitality (11%), insurance (11%), telecommunications (10%), and financial services (8%), with the remainder spread across other industries. Revenue concentration is notable at the customer level — the top ten customers accounted for more than one-third of 2025 revenue, and a single customer exceeded 10%.

4. Competitive Landscape

Zeta's 10-K does not name specific competitors, describing the market instead as highly fragmented with most rivals offering narrower point solutions rather than a unified platform. Based on the publicly known marketing-technology landscape, Zeta competes against:

• Large enterprise marketing-cloud incumbents: Salesforce (Marketing Cloud), Adobe (Experience Cloud), and Oracle (Marketing Cloud/CX), which offer broader enterprise software suites with marketing as one module among many — larger balance sheets but often less unified identity data than Zeta's purpose-built platform.
• Dedicated customer-engagement and messaging platforms: companies such as Braze and Twilio/SendGrid, which compete most directly on the omnichannel messaging and CDP layer.
• Programmatic/demand-side platform specialists: competing for the same ad-buying budget that Zeta's DSP targets.
• A long tail of point-solution vendors: specialized tools for email, SMS, or data management that customers might otherwise stitch together instead of buying Zeta's unified platform — the fragmentation Zeta explicitly cites as its core competitive opportunity.

Zeta's differentiated position is its proprietary, identity-resolved data layer combined with a single integrated platform spanning data, AI, and omnichannel activation — a pitch aimed squarely at customers currently paying for multiple disconnected point solutions.

5. Strategic Strengths & Risks

Strengths / Moat Sources:

• Proprietary identity data and the Zeta Data Platform, built over nearly two decades, which is genuinely difficult for a new entrant to replicate quickly and underlies the entire ZMP value proposition.
• High customer switching costs once integrated: a super-scaled customer running campaigns, data activation, and attribution through ZMP has deeply embedded the platform into its marketing operations, evidenced by 87% of 2025 revenue coming from just 184 such customers.
• Land-and-expand economics: growth in scaled (527→602) and super-scaled (148→184) customer counts shows the platform's ability to deepen existing relationships, not just add logos — a durable growth engine if it continues.
• Improving unit economics at scale: 30% revenue growth paired with a 21.4% Adjusted EBITDA margin and 2026 guidance for full-year GAAP net income shows the model scaling toward sustained profitability.

Risks:

• Customer concentration: the top 10 customers drove more than a third of 2025 revenue and one customer exceeded 10% — a level of concentration that makes any single large-customer loss materially impactful.
• Competition from much larger, better-capitalized incumbents (Salesforce, Adobe, Oracle) that can bundle marketing tools into broader enterprise software deals and underprice a standalone vendor.
• Still-emerging AI layer (Athena): the company's forward AI-agent narrative is not yet a mature, proven product per its own disclosure, creating execution risk if AI-driven differentiation does not materialize as marketed.
• GAAP net losses persisting through FY2025 ($31.5 million net loss) despite strong Adjusted EBITDA, reflecting continued stock-based compensation and other non-GAAP add-backs that investors must look past to see the "real" profitability story.
• Reduced disclosure going forward: management's plan to stop reporting scaled-customer counts in quarterly filings reduces investor visibility into one of the company's most important leading indicators.
• Large international workforce (~2,000 of ~3,300 employees outside the U.S.) introduces geopolitical, data-privacy, and labor-cost-structure risk exposure beyond the core U.S. market.

7. Summary Conclusion

Zeta Global has built a genuinely differentiated position in a fragmented marketing-technology market: a single, AI-native platform resting on nearly two decades of accumulated identity data, monetized through a land-and-expand model that keeps pushing customers from standard tiers up to "scaled" and "super-scaled" status. The concentration of 87% of 2025 revenue in just 184 super-scaled customers is both the clearest evidence of the model's effectiveness and its most important risk factor — Zeta's near-term growth is tightly tied to retaining and further expanding a relatively small number of large relationships.

With revenue scaling past $1.3 billion at 30% growth, Adjusted EBITDA margins above 21%, and 2026 guidance calling for the company's first full year of positive GAAP net income, Zeta appears to be transitioning from a growth-at-all-costs marketing-tech challenger into a maturing, profitable platform business. The central question for the next few years is whether its proprietary data and AI-native infrastructure moat is durable enough to keep winning business away from far larger, better-capitalized incumbents like Salesforce, Adobe, and Oracle as the broader marketing-cloud market consolidates.
