Instinct Raises $1B at $10B Valuation for AI Agent

Instinct, the San Francisco startup behind a viral personal AI agent, raised $1 billion in a Series C round at a $10 billion valuation, with Sequoia Capital, Benchmark Capital, and Coatue investing, the company said Monday, according to Reuters' report on the round.

The speed is the headline. Instinct announced a raise at a $2.5 billion valuation only about a month ago, and its service has been available on an invite-only basis since August 2026, according to TechCrunch's reporting. The prior round was a $250 million Series B, per founder Noah Shinn's comments to the Wall Street Journal as cited by Reuters, which makes this secondary-reported rather than restated in Instinct's own release, according to Ultrathink's breakdown of the announcements.

Instinct is pitched as a personal agent that handles tasks from start to finish. Users communicate by text or phone, and the agent uses its own computer and phone to plan trips, order groceries, cancel forgotten subscriptions, make reservations, and place calls, according to Tech Startups' coverage. Reuters notes the company has also released a concierge service meant to handle bookings and phone calls. Shinn's statement framed the goal directly: "We're building Instinct to be the best personal agent that can handle the deeply personal nuances of everyday life."

Instinct has not shared user numbers, revenue, or any growth metrics, and TechCrunch notes the same. That matters because a $10 billion valuation is resting on investor conviction about a category, not on published traction. The company also declined interviews with Shinn alongside the announcement, offering only a written statement.

An agent that makes calls, spends money, and acts in a user's name needs a much higher level of trust than a chatbot. Instinct says it built isolated sandboxes, short-lived local credentials, and identity-signed tool execution into the product from the start, plus what it calls an "active detective system" to catch hallucinations before the agent acts, according to Tech Startups. Those are company claims that outsiders have not tested. Instinct's data terms have also drawn scrutiny before: our coverage of Ollie's raise noted Instinct was criticized for terms of service granting a broad license over user materials, a contrast Ollie used to market its no-data-sale model.

The round lands as Meta's Muse dominates consumer attention. TechCrunch points out that Muse can do much of what Instinct does, plus tasks such as summarizing Instagram DMs and watching Marketplace listings, and it has climbed to the top of the App Store, as we covered when Muse overtook ChatGPT in downloads. Muse is also targeting subscription cancellation, one of Instinct's headline tasks, as we reported in our look at how Muse is attacking the subscription economy. A startup with an invite-only product now faces a rival with nearly 4 billion existing users across Meta's apps.

For investors and founders, the round is a data point on how much capital is chasing consumer agents that complete tasks rather than answer questions. A fourfold markup in about a month reflects category fervor more than measured performance, so comparable valuations deserve skepticism until usage data appears.

For businesses that sell to consumers, the practical shift is that agents may soon place calls, book, and cancel on customers' behalf. Companies should plan for agent-driven interactions, including how their phone lines, booking flows, and cancellation processes respond to software acting for a person rather than the person themselves.

How much did Instinct raise and at what valuation?
Instinct raised $1 billion in a Series C at a $10 billion valuation, with Sequoia Capital, Benchmark Capital, and Coatue participating, according to the company's announcement.

What does the Instinct AI agent do?
It is a personal agent that users text or call to plan trips, order groceries, cancel subscriptions, make reservations, and place phone calls, completing the whole task rather than only suggesting steps.

Has Instinct shared how many users it has?
No. Instinct has not disclosed users, revenue, or growth metrics, and its service has been invite-only since August 2026.

Instinct raised $1 billion in a Series C at a $10 billion valuation from Sequoia Capital, Benchmark Capital, and Coatue, roughly a month after a round reported at $2.5 billion. The San Francisco company's personal agent texts and calls on users' behalf to plan trips, order groceries, cancel subscriptions, and make bookings, but it remains invite-only and has disclosed no user or revenue figures. It faces direct competition from Meta's Muse, and its security claims, including isolated sandboxes and short-lived credentials, are the company's own and untested by outsiders.
