In 2025, a 7% revenue jump for a major furniture retailer wasn't just a good quarter—it was a revolution. That spike came from Sequen, a startup founded by former Etsy AI lead Zoë Weil, whose work once drove a billion-dollar increase for the marketplace. Today, her company announced a $16 million Series A to bring the real-time personalization engines of tech giants to mainstream consumer businesses.

Sequen’s core technology, what Weil calls a Large Event Model, doesn't just analyze text. It interprets streams of live user behavior—hovers, conversations, clicks within a session—to predict intent instantly. "The tech isn't recommending anymore," Weil explains. "It's understanding desire as it forms. That’s why people sometimes think their phone is listening."

This approach aims to make the traditional tracking cookie obsolete. By focusing on anonymous, real-time events rather than stored user profiles, Sequen personalizes without persistent identity data. Decisions are made in under 20 milliseconds.

For clients like Fetch Rewards, the results are stark: a 20% net revenue increase in under two weeks. Sequen sells access via its RankTune platform, with pricing based on requests per second. Initial contracts are already in the seven-figure range, with customers frequently opting for the highest tier after a single successful test.

The New York-based team of fourteen, with alumni from DeepMind and Meta, is led by Weil and co-founders from Etsy and the AI research world. The round was co-led by White Star Capital and Threshold Ventures, bringing Sequen’s total funding to $22 million. In less than 18 months, they’ve processed 10 billion monthly requests, proving that the most potent tech in Silicon Valley can now run far beyond it.
