Zest’s new AI agent finds restaurants and books reservations over text

Zest, the restaurant discovery app that launched earlier this year, is already thinking about a future where mobile apps are no longer the primary interface. On Thursday, the startup introduced a new feature: a personal AI-powered “restaurant concierge” that lives in your text messages, similar to other popular AI agents like Instinct or Poke.

The launch reflects a broader shift in how startups are thinking about AI, as conversational AI agents take on tasks that had previously required users to launch standalone mobile apps. For Zest, that means bringing its restaurant recommendations into texts, then allowing users to immediately take the next step of booking a table.

“The agent is the product now,” explains Zest founder and CEO Mario Gomez-Hall. “You text it, and it answers from your own history and your friends’. It doesn’t need weeks of conversation to learn you because it starts from where you’ve actually been,” he said.

Originally founded in November 2024, with $1.8 million in pre-seed backing from Alexis Ohanian at 776 and Steve Jang at Kindred Ventures, the app’s unique feature is that it links up with users’ credit cards to track where they’re actually eating out to get a sense of their tastes and interests. With this data on hand, Zest can make tailored suggestions of what places you might like to try next, whether that’s in your own city or suggestions of places to try when you’re traveling.
