AI Startup Instinct Valued at $2.5 Billion After $250 Million Round
Personal AI assistant startup Instinct, founded by 23-year-old Noah Shinn, raised $250 million in a Series B round that pushed its valuation to $2.5 billion, even as the product remains in closed beta.

Instinct, the startup behind a phone-based AI assistant designed to handle everyday tasks on users' behalf, has raised $250 million in a Series B funding round. The round was co-led by Index Ventures and Benchmark, pushing the company's valuation to $2.5 billion.
Instinct operates as an assistant reachable by phone call and text message, rather than another chat app. Instead of answering questions, it's meant to carry out concrete tasks: replying to emails, coordinating a calendar, booking airport transport, hiring contractors for home repairs, comparing insurance offers, doing grocery shopping, or searching for a rental apartment.
From Zero to Billions in Months
The company was founded in 2025 by Noah Shinn, a 23-year-old former researcher at Sierra, the AI company co-founded by former Salesforce co-CEO Bret Taylor. Instinct's private testing only began in February 2026, yet the product had already gone viral in Silicon Valley before its public launch.
The pace of the valuation's growth is unusual even by AI industry standards. Investors are racing to fund personal AI agents that don't just respond to commands but independently take action on a user's behalf, connecting to their email, messaging apps, screen, audio, and location.
What Users Are Doing
According to the founder, early users have used Instinct for things like planning cross-country trips, weekly grocery shopping, buying concert tickets, and canceling subscriptions worth hundreds of dollars. One user reportedly even had the assistant help with buying a house.

Data and Security Concerns
The product's growing popularity has also drawn privacy criticism. Instinct's terms of service allow the company to use user data to train its own models, and the assistant itself requires broad access to sensitive information such as message content, screen images, audio, and device location. The company acknowledges that its security controls are still being developed as the service scales.
It's a recurring pattern in the segment of AI agents operating autonomously on users' devices: the broader the permissions an assistant is granted, the greater the risk of data leaks or unauthorized action taken in the account owner's name.
What It Means for the Market
Instinct's case shows how much capital is currently flowing toward consumer-focused AI agents, not just business-oriented ones. Venture capital funds that previously bet mainly on tools for developers and companies are increasingly willing to fund products meant to replace a personal assistant or secretary for the average smartphone user.
For the Polish market, this story remains geographically distant for now, since Instinct stays in a closed beta with no announced expansion beyond the United States. Still, it points to the direction competitors are heading: AI agents with access to a user's inbox, calendar, and payments are no longer an experiment but a product valued at billions of dollars before it's even publicly available.
