Listen to the news

Oil prices are holding near US$100 a barrel after renewed conflict in the Middle East and fresh shipping disruptions. Higher energy costs can squeeze slow growing businesses. They often reward firms that are expanding quickly and run by leaders with serious skin in the game. This article breaks down three fast growing, heavily owner led stocks from our screener so you can see which profiles fit your watchlist.

The three stocks below are a small sample, and the full screen surfaced 1,301 more companies with equally compelling insider backed growth stories that are not covered here. To go straight to the source and identify your own highest conviction ideas, analyze the Fast Growing Stocks With High Insider Ownership screener.

Zeta Global Holdings (ZETA)

Zeta Global Holdings gives this screener a pure play on fast, data-driven marketing growth, using its AI tools to help big brands win and keep customers while analysts and management both discuss the longer term potential.

Zeta Global runs an AI-driven marketing cloud that helps enterprises use data to acquire, grow, and retain customers across channels, generating about US$1.57b in Internet Software & Services revenue. The business is valued around US$7.9b in the market.

"Zeta's AI-driven platform and unique data approach position it for market share gains, revenue growth, and strong customer retention as industry adoption evolves."

The key factor to watch is how one emerging pressure on future margins develops as this platform scales into larger customer budgets.

That margin pressure is only one piece of the story, and the full narrative for Zeta Global Holdings explains how Zeta Global Holdings could still convert its data edge into accelerating owner led upside.

AppLovin (APP)

AppLovin leans into this screener’s fast growth plus insider ownership theme through its AI advertising tools, which management and analysts both point to as the key engine behind its outlook.

AppLovin runs an AI driven advertising platform for app developers and brands, with its Advertising segment generating about US$6.8b of revenue and the group valued around US$107.3b in the market.

"Expanded rollout of the self-service AXON ads manager and Shopify integration is expected to open AppLovin's platform to a massive new base of small and mid-sized advertisers globally, dramatically increasing advertiser count and driving sustained uplift in topline revenue."

What really matters next is how one emerging constraint on growth efficiency shapes future returns on all that AI fueled ad spend.

That growth efficiency question is exactly what the full narrative for AppLovin unpacks, highlighting where AppLovin’s AXON engine could accelerate, stall, or quietly decouple results from ad spend.

Zscaler (ZS)

Zscaler gives this screener direct exposure to Zero Trust security and Security for AI, using its cloud platform to secure access to apps and data as enterprises push harder into digital transformation and AI tools.

Zscaler, a US$27.7b cloud security company, generates about US$3.35b from subscription and support tied to its Zero Trust SASE and related services, with customers across the US, EMEA, Asia Pacific, and other regions.

For investors looking at fast growing, insider backed stories, Zscaler offers a pure cloud security platform. Zero Trust SASE and AI driven security operations are central to the growth case rather than a side bet.

"Accelerating customer adoption of Zero Trust Everywhere and Data Security Everywhere solutions, particularly among Global 2000 and Fortune 500 firms, is fueling large upsell deals and higher ARR per customer, which should drive sustained double-digit revenue growth and improve net retention rates."

What could really shift the outcome for Zscaler is how one emerging cost and investment trade off eventually feeds through to margins and cash generation.

That trade off sits at the center of the full narrative for Zscaler, which maps how Zscaler’s spending today could accelerate or quietly cap tomorrow’s upside.
