The IronSource founders sold an ad tech company for $4.4 billion. Their next bet is that AI agents will replace the ad buyers their old company served.

Mobile ad veterans Tomer Kagan and Eyal Katz are pivoting from ad tech to AI-driven agent automation, betting that software agents will supplant human ad buyers in the $150 billion mobile app monetization market, a space they helped shape with IronSource's $4.4 billion sale to Unity in 2022. Their new venture, which leverages reinforcement learning and natural language processing, aims to streamline ad buying and selling through AI-facilitated negotiations. AI-assisted, human-reviewed.

Tomer Kagan and Eyal Katz, the founders of IronSource, have launched a new venture called Zyg, which aims to automate advertising, retention, support, and inventory forecasting for direct-to-consumer sellers using AI agents. The company has raised $60 million at a $500 million valuation, led by Accel, and is entering a category that barely existed twelve months ago.

Overview

Zyg is an agentic operating system for e-commerce scale, which automates business functions that direct-to-consumer sellers currently manage through a combination of human operators, fragmented software tools, and advertising agencies. The platform's AI agents are designed to replace the people who run e-commerce advertising, and are already running advertising campaigns on Meta's platforms.

What Zyg Does

Zyg's agents automate campaign creation and optimization on Meta and other platforms, customer retention, support, and inventory forecasting. The company's customer base includes businesses with between $2 million and $15 million in annual revenue, which is the segment of the e-commerce market large enough to need sophisticated advertising but too small to afford the teams that run it.

Tradeoffs

The incumbents in e-commerce advertising, such as Meta, Google, Amazon, and Shopify, are building AI automation directly into their platforms. Zyg's wager is that the multi-platform problem is unsolvable from inside any single platform, and that a DTC brand needs an agent that understands the business as a system, not a collection of channels.

When to Use It

Zyg's platform is designed for direct-to-consumer sellers who need to automate their advertising, retention, support, and inventory forecasting. The company's AI agents are designed to replace the people who run e-commerce advertising, and are already running advertising campaigns on Meta's platforms.

Pricing

The funding will be primarily used to hire AI talent in Israel, a market where the competition for researchers and engineers has intensified as global companies and domestic startups chase the same pool of specialists.

Bottom Line

Zyg's $500 million valuation is a bet on the company's ability to automate e-commerce advertising and replace the people who run it. The company has two months of post-stealth existence and $118 million in capital to find out whether its valuation was prescient or premature.

Zyg's founders have a proven track record of building successful companies, and their understanding of advertising infrastructure at a technical level gives them an advantage in the AI agent market. The company's AI agents are designed to understand the business as a system, not a collection of channels, and are already running advertising campaigns on Meta's platforms. Whether Zyg's valuation will hold up remains to be seen, but the company's potential to disrupt the e-commerce advertising market is undeniable.
