Zeta Global $ZETA Posts 114% Net Retention, 35% Revenue Growth in Q2 2025, Valued at 3.5x Sales

In the rapidly evolving landscape of marketing technology, companies that deliver exceptional customer retention and return on investment (ROI) stand out as prime opportunities for investors. Zeta Global Holdings Corp, a leader in AI-powered marketing solutions, exemplifies this by achieving a net revenue retention rate of 114%, signalling that existing customers not only remain loyal but also expand their spending. This metric underscores the company’s ability to provide a comprehensive, full-stack platform that addresses diverse marketing needs, ultimately driving superior ROI in an industry where efficiency and measurable outcomes are paramount. With shares trading at levels that imply a valuation of approximately 3.5 times forward sales—based on analyst projections for robust growth—this setup presents a compelling case for those eyeing sustainable expansion in the martech sector.

The Power of Retention in Marketing Technology

Customer retention serves as a critical barometer for success in the marketing technology (martech) industry, where platforms must continually prove their value amid fierce competition and shifting digital trends. A net revenue retention rate of 114% indicates that for every dollar of revenue from existing customers in the prior period, the company generates $1.14 in the current one, factoring in expansions, contractions, and churn. This figure is particularly impressive in martech, where average retention rates often hover around 100% or below for many players, according to industry benchmarks from sources like Gartner.

Zeta Global’s performance in this area stems from its integrated approach. The company offers a full-stack solution encompassing customer data platforms, marketing automation, and AI-driven insights, allowing brands to manage acquisition, growth, and retention seamlessly. Unlike fragmented tools that require multiple vendors, Zeta’s platform unifies these functions, reducing complexity and enhancing efficiency. This holistic model has proven especially valuable as businesses grapple with data privacy regulations and the phasing out of third-party cookies, forcing a pivot towards first-party data and personalised engagement.

Recent quarterly results highlight the tangible benefits. In its Q2 2025 earnings, Zeta reported revenue of $308 million, marking a 35% year-over-year increase, driven by a 21% rise in scaled customers and an 11% uptick in average revenue per user (ARPU). Such growth reflects not just new client wins but also deeper penetration within existing accounts, aligning with the high retention narrative. Analyst sentiment, as captured by ratings averaging a ‘Buy’ with a score of 1.6 on a scale where 1 is strong buy, reinforces confidence in this trajectory.

Delivering Industry-Leading ROI

At the heart of Zeta’s retention success is its focus on delivering the strongest ROI in the martech space. By leveraging artificial intelligence to analyse billions of consumer signals, the platform predicts intent and personalises experiences across channels like email, social media, and connected TV. This precision targeting minimises wasteful spending and maximises conversion rates, often yielding ROI multiples that outpace competitors.

For instance, case studies from Zeta’s operations show clients achieving up to 4x higher conversion rates through tools like Zeta Answers, an AI framework unveiled in mid-2025 that enhances marketing efficiency. A national furniture chain consolidated its lifecycle and acquisition marketing on Zeta’s platform, resulting in improved ROI and customer stickiness. Similarly, a hospitality brand expanded from growth to retention use cases, demonstrating the platform’s versatility. These examples illustrate how Zeta transforms from a point solution into an end-to-end partner, fostering long-term relationships.

Industry analysis supports this edge. According to a GuruFocus report on Zeta’s Q2 2025 earnings, the ‘One Zeta’ initiative is accelerating multi-use case adoption, leading to better ROI and retention. In a market where digital marketing budgets face scrutiny, Zeta’s data-driven approach positions it as a disruptor, with AI tools enabling smarter spending and measurable results.

Valuation Perspective: Attractive at 3.5x Sales

Valuation metrics further bolster the investment thesis. As of 12 August 2025, Zeta Global shares closed at $18.53, reflecting a market capitalisation of approximately $4.41 billion. With forward revenue estimates pointing to around $1.26 billion for 2025—based on company guidance and analyst models—this implies a price-to-sales ratio of about 3.5x. For a company exhibiting 35% revenue growth and expanding margins, this multiple appears undervalued compared to martech peers trading at 5x to 7x sales.

Looking ahead, management’s roadmap targets $2.1 billion in revenue by 2028, with adjusted EBITDA margins reaching 25% and free cash flow margins exceeding 16%. If achieved, this would represent a compound annual growth rate of over 20%, justifying a premium valuation. Forward P/E ratios stand at 25.04 based on expected EPS of $0.74, while the current year’s P/E is 28.20 on $0.66 EPS, suggesting room for expansion as profitability improves.

Comparative analysis reveals Zeta’s edge. While competitors in the AI marketing space face headwinds from market saturation, Zeta’s 44% penetration among Fortune 100 companies and net cash position of $160 million provide a buffer. The stock’s 52-week range of $10.69 to $38.20 indicates volatility, but recent performance—up 23.44% over the 50-day average of $15.01—signals building momentum.

Risks and Considerations

Despite these strengths, investors should note potential risks. The martech sector remains competitive, with players like Adobe and Salesforce vying for market share. Zeta’s public sector business is nascent, and continuous investment in AI and sales is required to sustain growth. A GAAP net loss of $12.8 million in Q2 2025, though improved, highlights the path to full profitability.

• Competition: Zeta faces rivals with deeper pockets, though its AI focus differentiates it.
• Economic Sensitivity: Marketing budgets can contract in downturns, impacting retention.
• Regulatory Shifts: Evolving data privacy laws could affect operations.

Nevertheless, with a ‘Buy’ rating from analysts and strong fundamentals, the risk-reward profile leans favourable.

Strategic Implications for Investors

Zeta Global’s blend of high retention, superior ROI, and attractive valuation positions it as a standout in martech. As brands increasingly demand integrated, AI-powered solutions, companies like Zeta are poised to capture share. Investors might consider this as part of a growth-oriented portfolio, particularly given the sector’s projected expansion to $500 billion by 2028, per Statista models.

In summary, Zeta’s 114% net retention rate and full-stack capabilities signal a business built for endurance, delivering outsized value in a data-centric world. At current multiples, it offers a timely entry point for those betting on AI’s role in marketing transformation.
